Order Book Trading Platforms

Coinstore is a centralized crypto-to-crypto exchange founded in Singapore in 2021 that operates an orderbook-based spot market covering more than 1,100 listed tokens and over 410 trading pairs. Spot fees are set at a flat 0.2% for makers and takers, with periodic zero-fee campaigns for selected pairs. CoinCodex places the exchange's reported 24-hour spot volume at approximately $1.9 billion, ranking it around 57th globally, though verified volume figures from other sources are materially lower. The platform has been an active early-listing venue for Solana ecosystem projects, adding 15 to 20 new tokens per month and partnering with Waterdrip Capital in 2024 on a Solana-focused event in Dubai. Coinstore does not support native fiat on-ramps and restricts access from residents of the United States, Mainland China, Hong Kong, Singapore, and sanctioned countries.

CoinW operates a centralized orderbook exchange with a spot market covering more than 500 listed cryptocurrencies and over 400 active trading pairs, including major assets such as Bitcoin, Ethereum, and Solana alongside DeFi tokens, meme coins, and smaller-cap altcoins. The platform's matching engine, upgraded to a 2.0 architecture in 2021, supports microsecond-level trade execution designed to reduce slippage and improve order fill quality during high-volume periods. Spot trading fees follow a tiered VIP structure beginning at 0.2% for both makers and takers at the entry level and scaling down to 0.01% at the highest tier, with CWT token holdings determining tier placement. The exchange reports daily trading volumes that routinely reach several billion dollars, with peaks above $8 billion during active market conditions, across a user base of over 20 million registered accounts spanning 200+ countries.

Foxbit is Brazil's longest-running centralized cryptocurrency exchange, founded in October 2014 and serving more than 1.5 million registered users across the country. The platform operates a full-featured spot trading venue supporting over 100 cryptocurrencies across 106 trading pairs, all denominated against the Brazilian real. Foxbit's fee structure charges 0.50% for takers and 0.25% for makers, with a VIP tier program offering discounts for high-volume participants. The exchange provides robust API infrastructure through a v3 architecture with REST and WebSocket endpoints, enabling algorithmic traders and developers to interact with the platform programmatically. Brazilian residents can fund accounts using PIX, Brazil's real-time payment network, or credit cards, providing frictionless BRL on-ramp access to Solana, Bitcoin, Ethereum, and over 100 other supported assets. With cumulative transaction volume exceeding 50 billion Brazilian reais, Foxbit handles a substantial share of BRL-denominated crypto trading activity in the country.

Rain Pro is Rain's advanced trading interface for active traders in the MENA region, providing a full order-book environment with live charts, technical indicators, and support for market and limit order types. It operates on a maker-taker model where makers pay zero fees and takers pay 0.05% per trade — well below the 0.5% spread on Rain's standard brokerage interface. More than 150 cryptocurrencies trade across eight regional fiat currencies including BHD, AED, SAR, and KWD, all within a licensed, CBB-regulated venue. Rain holds a Category 3 crypto-asset services license from the Central Bank of Bahrain — the first of its kind issued in the Middle East — plus a Financial Services Permission from Abu Dhabi Global Market and in-principle approval from Dubai's VARA. An OTC desk complements Rain Pro for institutional and high-volume clients, while a partnership with Kraken enables trading of tokenized equities in eligible jurisdictions.

VALR operates a full-service spot order book across more than 100 digital assets and is Africa's largest cryptocurrency exchange by trading volume. Its deepest markets are ZAR-denominated pairs including BTC/ZAR, ETH/ZAR, XRP/ZAR, and SOL/ZAR, offering local currency order book depth that global platforms historically lacked for South African traders. The platform also supports spot margin trading with up to 5x leverage on major pairs. VALR uses a tiered maker-taker fee model with 0 percent base maker fees and taker fees starting at 0.05 to 0.1 percent. Traders in ZAR-denominated markets receive a negative 0.01 percent maker rebate, earning a small fee for adding liquidity to the book. The exchange serves approximately 2 million registered users and over 1,900 institutional clients, has processed more than 23 billion USD in cumulative volume, and operates an institutional OTC desk for large-block trades outside the public order book.

UzNEX operated as a centralized spot exchange serving traders in Uzbekistan and across Central Asia, executing trades across pairs including BTC/USDT, ETH/USDT, BTC/USD, ETH/USD, and ETH/BTC. It distinguished itself from regional alternatives by accepting the Uzbek som (UZS) alongside US dollars and credit cards, making it the first exchange in Central Asia to offer fiat on-ramps denominated in the national currency. The platform held Uzbekistan's inaugural crypto exchange license, issued in December 2019, and renewed its authorization in February 2024 as License No. CE#0003. By 2024, UzNEX had accumulated cumulative trading volume of approximately $1.38 billion, growing from a niche non-resident venue into Uzbekistan's dominant regulated trading platform before closing in May 2026 after its parent company, KOBEA Group, requested cancellation of its license.

Upbit is the largest spot cryptocurrency exchange in South Korea, commanding approximately 90 percent of domestic crypto trading volume and ranking among the largest exchanges globally by spot volume. The platform lists approximately 200 cryptocurrencies across Korean Won (KRW), Bitcoin, and USDT markets, with the KRW pairing dominant by volume. Upbit offers no futures, perpetuals, or margin products, restricting itself to direct spot transactions that align with South Korean regulatory expectations and serve a retail-focused user base. Fee structure is transparent: KRW-market trades carry a 0.05 percent flat maker-taker fee; BTC and USDT market trades are 0.25 percent; high-volume traders with 5 million USD in rolling 30-day volume receive 0.04 percent across all markets. Solana (SOL) trades in the KRW market, giving Korean retail investors direct fiat access without needing BTC or a stablecoin as an intermediate currency. Upbit also applies an active delisting policy, removing assets that fall below liquidity thresholds or present security concerns.

Bitso's core exchange supports spot trading across more than 100 cryptocurrencies, with pairs against Mexican Peso, Brazilian Real, Colombian Peso, Argentine Peso, and US Dollar. Bitso Alpha is the platform's professional trading layer, offering advanced order types and deeper market data for active and institutional traders on the same underlying infrastructure. In 2025, Bitso launched Bitso Onchain, a self-custody DEX supporting over 17,000 tokens across 14 blockchain networks including Solana, Ethereum, Arbitrum, and Base, with cross-chain swaps executable in a single transaction. Gas fees are covered by Bitso and seed phrases are not required, removing the two largest technical barriers that have historically kept retail users away from on-chain trading.

PDAX operates genuine peso-denominated order books that let Philippine users buy and sell over 50 cryptocurrencies directly against the Philippine peso, rather than routing through broker-quoted prices. Spot trading uses maker and taker fee structures of 0.40% and 0.50% respectively, with full limit order functionality available through the web-based exchange for users who want precise control over entry and exit prices. The exchange's order book infrastructure extends beyond its own platform, powering GCrypto inside GCash, the Philippines' largest mobile wallet with tens of millions of active users. In July 2025, GrabPay users also gained the ability to fund wallets using cryptocurrency through PDAX, making the platform's pricing engine one of the most widely distributed in the country.

MAX Exchange is MaiCoin Group's professional trading platform, launched in 2018 and listing more than 50 digital assets against New Taiwan Dollars and major stablecoins. The exchange operates a maker/taker fee structure of 0.05% and 0.15%, with fee discounts available through the platform's native MAX Token. Recent asset additions include NEAR, ONDO, AAVE, TAO, UNI, and XLM, alongside Solana and SPL tokens GMT and USDC. The platform extends beyond standard spot trading to include strategy bots, grid trading, and crypto borrowing. MAX Exchange is registered with Taiwan's Financial Supervisory Commission for AML compliance and implements the FATF Travel Rule. With over one million registered users and more than $12 billion in average annual transaction volume across MaiCoin Group, MAX serves as Taiwan's primary regulated venue for professional digital asset trading.

Indodax is Indonesia's oldest and largest cryptocurrency exchange, operating a real-time limit-order-book engine where users trade more than 500 digital assets directly against the Indonesian Rupiah (IDR). Founded in 2014 as Bitcoin.co.id, the platform now serves over 10.1 million registered members and processes an average of 10 trillion IDR in monthly volume. It supports market, limit, and stop orders across its full asset catalogue. Trading fees follow a maker-taker model: IDR market trades carry 0.1% maker and 0.2% taker fees, while USDT market trades cost 0.03% maker and 0.06% taker. With a minimum trade size of Rp10,000 and integration with Indonesian bank transfers, e-wallets, and virtual accounts, the exchange is designed for domestic retail accessibility. Licensed under OJK's PAKD framework, Indodax is the primary regulated order-book venue for Indonesian retail participation in crypto markets.

Fiahub's trading platform offered a Basic tier covering approximately 22 cryptocurrencies and a Pro tier spanning more than 100 digital assets and over 300 trading pairs. Available assets included Bitcoin, Ethereum, Solana, USDT, BNB, XRP, and DeFi tokens such as Chainlink, Aave, and Uniswap. The exchange ran a VIP membership program that reduced trading fees by up to 60 percent for higher-tier users, alongside customer support structured to resolve queries within one business day. Operating as a bootstrapped business incorporated in Singapore, Fiahub served Vietnamese retail users from April 2018 until its suspension on July 31, 2026, following the introduction of Vietnam's crypto licensing regime.

Bitlo is a centralized order-book exchange headquartered in Istanbul, Turkey, serving over two million registered users since its 2018 launch. The platform maintains dedicated Turkish Lira (TRY) order books across more than 280 digital assets including Bitcoin, Ethereum, Solana, and a broad range of altcoins, giving local investors direct price discovery without foreign-currency conversion. Bitlo's trading engine supports both a Basic interface for newcomers and an Advanced charting environment for experienced traders. A tiered maker-taker fee model rewards higher-volume accounts with rates as low as 0% for makers, and the native BTL token provides additional fee discounts across all trading pairs.

SAFEbit is Turkey's regulated cryptocurrency exchange rebuilt from the legacy Bitci Teknoloji platform following a full corporate acquisition in May 2025. At its core, it operates a centralized exchange with an order-book spot market supporting approximately 139 listed coins and 170 trading pairs. Users fund accounts via 24/7 Turkish lira bank transfers after completing KYC verification, enabling seamless domestic on-ramping for Turkish retail investors. The trading interface includes percentage-based order shortcuts for position sizing, delivering a structured spot-trading experience in one of the world's most active crypto adoption markets. The exchange holds SPK (Capital Markets Board) authorization with 500 million TRY in disclosed paid-in capital and lists major Solana ecosystem tokens including SOL, JTO, and PUMP alongside USDT pairs. Security infrastructure includes cold wallet storage for the majority of user funds, mandatory two-factor authentication, and independent security audits. Reporting approximately $71 million in 24-hour trading volume across 170 active trading pairs, SAFEbit operates at meaningful scale for a regional CEX and represents the institutional face of regulated crypto spot trading in Turkey's rapidly formalizing environment.

CoinTR operates a centralized order-book spot exchange supporting over 200 cryptocurrencies and more than 280 trading pairs denominated in Turkish Lira (TRY) and USDT. Its proprietary third-generation trading system offers two interfaces: a simplified buy/sell module for beginners and an advanced view with full order-book depth, limit and market orders, and integrated charting tools. All spot trading is offered on a commission-free basis. The platform also provides a spot grid trading bot that automates range-bound strategies by executing buys and sells within user-defined price levels and grid increments, giving traders systematic exposure without active order management.

Panora's limit order system allows traders to specify a target price at which a swap should execute, with the order running fully on-chain and no intermediary holding assets between placement and fill. Users retain custody of their tokens until the moment of execution, making this a non-custodial alternative to market orders for participants who want precise price control. A dollar-cost averaging mode extends the automation further, enabling recurring purchases at preset intervals without requiring manual monitoring. The platform also incorporates on-chain order book venues (CLOBs) as one of several liquidity sources within its meta-DEX routing engine, treating them alongside AMMs and concentrated liquidity pools when computing best execution. This dual role — offering native non-custodial limit orders while aggregating CLOB liquidity for spot routing — positions Panora as a comprehensive order-management and execution layer across the Aptos trading ecosystem.

Stillman Digital is an institutional algorithmic market maker supplying two-sided liquidity across centralized limit order books through direct exchange partnerships. The market-making desk manages approximately $400 million in monthly volume, with infrastructure co-located in NY4 and LD4 Equinix data centers to minimize latency and co-integrated into Finery Markets' ECN, streaming firm quotes to payment companies, OTC desks, and brokers. Clients access a 24/7 streaming price feed aggregated from over 30 global exchanges, executable via web portal or API with support for TWAP and VWAP order types. Monthly electronic trade execution volume exceeds $500 million, and the firm crossed $30 billion in lifetime trading volume by April 2025 — scaling sharply after its October 2024 acquisition by Nasdaq-listed DeFi Technologies and its integration into DeFi Alpha, the group's arbitrage desk targeting on-chain venues including Solana.

NDAX is a Calgary-based, CIRO-regulated cryptocurrency exchange delivering a full-featured order book trading experience for Canadian retail and institutional investors. Supporting more than 65 cryptocurrencies at a flat 0.2% fee, the platform provides limit orders, stop orders, trailing stop orders, and fill-or-kill orders alongside TradingView-powered charting. An Auto-Invest feature enables scheduled accumulation, while CAD deposits via Interac e-Transfer, EFT, and wire transfer lower the on-ramp friction for Canadian users. With over $17.5 billion in cumulative trading volume and roughly $1 billion in assets under custody, NDAX has built one of Canada's most established crypto trading venues. An OTC desk and API access extend the platform to high-volume and algorithmic participants. As the Official Crypto Trading Platform Partner of the NHL's 2025 Stanley Cup Playoffs — the first such partnership in league history — NDAX combines mainstream consumer visibility with a compliance profile that few exchanges in the country can match.

Independent Reserve is an Australian cryptocurrency exchange that has operated a regulated order-book trading platform since 2013, making it one of the longest-continuously-running digital asset venues in the Asia-Pacific region. The platform supports spot trading across approximately 30 cryptocurrencies and stablecoins, including Bitcoin, Ethereum, Solana, and Solana-ecosystem tokens such as Bonk and Dogwifhat, with tiered fees ranging from 0.02% to 0.5% based on 30-day trading volume. Advanced charting is delivered through an embedded TradingView interface that gives traders access to technical indicators and drawing tools directly alongside the live order book. A full trading API covering order management, market data, and account operations is available for developers and algorithmic traders. Beyond standard order entry, the platform extends its offering with AutoTrader, a suite of three rule-based investment tools covering recurring purchases, calendar-scheduled execution, and systematic basket allocation across multiple assets. Leverage trading of up to 5x is available on Bitcoin, with a 0.1% daily interest fee on borrowed funds. For institutional and high-net-worth counterparties, a dedicated OTC desk processes trades from A$50,000 up to A$50 million per transaction, providing large-block execution outside the public order book with direct settlement, competitive pricing, and a dedicated relationship manager who can access deep global liquidity.

CoinJar Exchange is a professional-grade trading platform offering 200+ trading pairs across AUD, USD, and GBP fiat currencies alongside crypto-to-crypto markets. Traders access limit orders, stop orders, and time-in-force order types, with API access for algorithmic strategies. The matching engine is described as among the fastest in the world. The fee structure follows a tiered 30-day volume model, with standard crypto/fiat pairs priced at 0.06–0.10% taker and 0.02–0.10% maker. SOL trades against AUD, GBP, and USD fiat pairs on the professional exchange at standard maker/taker tiers. Crypto-to-crypto pairs carry a 0.06% taker fee with zero maker fee, while stablecoin pairs can be as low as 0.001% taker. The platform also provides an OTC trading desk for institutional or high-net-worth clients requiring large-volume execution without market impact. Founded in 2013, CoinJar brings over a decade of exchange operations to professional traders across Australia, the UK, and the European Union.

Definitive brings institutional order-book-style execution discipline to on-chain DeFi, offering limit orders, stop loss, take profit, TWAP, DCA, and bracket orders that are largely absent from standard retail DeFi interfaces. All order types execute through audited smart contracts across nine blockchains, delivering algorithmic sophistication usually reserved for centralized prime brokers while preserving the non-custodial guarantees of self-custody. The platform co-founders come from the Coinbase institutional trading desk and designed the product to replicate professional CeFi order management without requiring KYC or custody transfer. The Flash API extends this order infrastructure programmatically, allowing quant funds, developers, and AI agents to integrate Definitive routing and algorithm engine directly into their own systems. Execution metrics validate the professional positioning: a 47-millisecond average latency and a 99.4% fill rate across 4.2 billion dollars in lifetime volume, powered by routing across 200-plus DEXs and 15-plus off-chain private market makers including block-trade venues suited for large orders. A May 2025 partnership with BlockFills further strengthened the automated trade-execution capabilities available on the platform.

Dex-Trade is a centralized exchange founded in 2017 that operates through a traditional order-book matching engine, connecting buyers and sellers via a central system rather than on-chain smart contracts. The platform supports over 500 coins and more than 1,000 spot trading pairs, with USDT, USDC, BTC, ETH, and TRX as quote currencies. Solana (SOL) is among the listed assets, giving traders centralized access to SOL exposure without on-chain wallets. TradingView charting with 13 timeframes and over 100 indicators supports technical analysis for active traders. Fees start at 0.1% for makers and 0.2% for takers, with a VIP tier system that progressively reduces rates for high-volume traders or DXU token holders. At the top VIP 4 tier, maker fees fall to 0.06% and taker fees to 0.12%. A demo mode mirrors live conditions for risk-free strategy testing, and API access plus iOS and Android apps extend trading to algorithmic and mobile users.

Finery Markets operates an institutional Electronic Communication Network that aggregates liquidity through three complementary execution modes: a firm-quote order book with zero rejection rate, continuous two-way quote streams from top liquidity providers, and a Request for Quote engine that solicits competitive real-time bids from multiple counterparties simultaneously. The platform connects over 150 institutional participants across more than 41 countries, including OTC trading desks, hedge funds, prime brokers, asset managers, and stablecoin issuers, with cumulative trading volume surpassing 60 billion dollars as of mid-2026. Finery Markets is non-custodial by design, functioning as a software infrastructure layer rather than a trading venue and never holding client assets. A single API gives institutional clients simultaneous access to all three execution modes, and SOL is among more than 200 supported trading pairs on the network. Key liquidity partnerships include Wintermute, GSR, and Enigma Securities, and the FM White Label product enables prime brokers and exchanges to embed the ECN technology into their own platforms under their own brand.

Swissquote launched SQX — its proprietary crypto exchange — in October 2022, built on a central limit order book that aggregates liquidity from multiple market-making hubs. CEO Marc Bürki framed the launch as a step toward deeper liquidity and faster execution, with tighter bid-ask spreads than routing through individual exchanges independently. SQX operates continuously within the bank's regulated environment and extended its market depth further in May 2024 through a partnership with institutional liquidity provider B2C2. The platform serves both Swissquote's retail client base and professional market participants matching larger institutional orders, all within the compliance perimeter of a FINMA-licensed Swiss bank.

LBank is a centralized cryptocurrency exchange founded in 2015 that operates via a traditional order-book model, pooling liquidity from over 20 million registered users across more than 210 countries. Traders deposit cryptocurrency or convert fiat via on-ramps, execute orders through the exchange's internal matching engine, and withdraw to external wallets. The platform lists over 800 cryptocurrencies at a spot fee of 0.10% for both makers and takers, below the industry average of roughly 0.20–0.25%. An Innovation Zone provides early price-discovery listings for newly launched altcoins—particularly Solana-native tokens—before they reach Tier 1 exchanges. LBank's order-book model serves traders who prefer a centralized interface over decentralized venues such as Raydium or Jupiter, avoiding the need for self-custody wallets and smart contract risk. The exchange's permissive listing cadence targets emerging altcoins that do not yet meet the standards of exchanges like Binance or Coinbase. Copy trading is supported through over 1,350 lead traders, with followers mirroring strategies proportionally. Grid trading bots and spot margin trading extend the platform's functionality for active traders seeking automation and amplified exposure within a custodial environment.

At its core, Orderly Network operates a single shared orderbook that more than 400 trading venues access simultaneously. This pooled approach means each venue inherits real market depth from the entire network rather than operating in isolation with fragmented liquidity. The matching engine runs off-chain for speed competitive with centralized exchanges, while settlement happens on-chain at intervals, preserving self-custody guarantees. The architecture is intentionally headless: Orderly handles the backend matching engine, smart contract settlement, and real-time order routing, while builders own the frontend interface, brand, and customer relationship. Traders deposit assets on-chain as collateral, and the system uses Ed25519 key-based authentication with a full REST and WebSocket API suite covering order placement, account management, real-time market data, and position tracking.

Gate lists over 4,900 cryptocurrency assets for spot trading via a traditional order book model, making it one of the widest asset catalogs among major centralized exchanges globally. Spot volume reached approximately 1.8 trillion USD in 2024, underpinning Gate's standing as a top-tier venue for liquid spot markets across a vast range of digital assets including SOL. The platform serves a user base that grew past 30 million registered accounts by mid-2025 and exceeded 59 million by mid-2026, reflecting the scale at which Gate's order book markets operate. For Solana holders, Gate provides one of the deepest global SOL spot trading markets, alongside support for hundreds of Solana-ecosystem tokens across its comprehensive asset listing.

BTCC operates as a centralized order-book exchange, acting as the counterparty clearinghouse for all trades and maintaining internal custody of user funds. Spot trading covers over 360 assets with maker fees of 0.2% and taker fees of 0.3%. An asset conversion tool supports instant conversion of 200 or more cryptocurrencies into USDT, enabling seamless funding transitions between spot holdings and futures positions. TradingView charting is integrated directly into the trading interface. Founded in June 2011 as BTC China, BTCC is the world's longest-operating cryptocurrency exchange, having processed trades through multiple market cycles including the 2013 peak and the 2022 collapse of several major competitors. The platform reported 431 billion USD in spot trading volume in 2025 and serves over 11 million registered users across more than 100 countries. New users receive a 100,000 USDT demo account to explore the interface before committing real capital.

The Pye Exchange is a dedicated order book marketplace for Principal Tokens (PT) and Reward Tokens (RT), the two SPL tokens produced by the Pye protocol's Programmable Stake Account system. PT trading enables buyers to acquire discounted SOL exposure by purchasing principal tokens below par and redeeming them at maturity for the full SOL equivalent. RT trading lets participants take positions on Solana staking yield without holding stake accounts directly. The exchange settles at fixed quarterly dates, creating a structured secondary market for otherwise illiquid staking exposure. Order book mechanics on the Pye Exchange are purpose-built for fixed-term staking instruments, where price discovery reflects both time-to-maturity and expected validator APY. Stakers use the exchange to exit yield positions early or hedge against APY fluctuations before term end. Five security audits from Zellic, Sec3, and Neodyme verify the safety of the underlying smart contracts. Pye launched the exchange in private beta in Q1 2026 with validator partners Solstice, Meria, and Stakin.

Uranium Digital's trading engine is built on a central limit order book (CLOB) that supports live bid-ask spreads and near-instant settlement for physical uranium tokens. The platform allows physical delivery participants and cash settlement traders to trade against the same order book, unifying the historically siloed sides of the uranium market in a single venue. This design mirrors how established energy commodity markets operate, supporting continuous 24/7 price discovery that the traditional uranium market entirely lacks. Orders settle through either physical delivery via licensed custodians or cash settlement for participants seeking price exposure without handling uranium. Built on Solana for its throughput and low costs, the orderbook is designed to meet institutional-grade performance standards while remaining accessible to smaller cash market participants.

Worm uses an order-book pricing model to aggregate liquidity across multiple platform sources rather than an automated market maker curve. The team cites this design choice as producing tighter spreads and more accurate price discovery, particularly significant given the 1x to 3x leveraged positions the platform offers on prediction market outcomes. Each market covers a verifiable event with resolution criteria drafted via an AI copilot, and the order book handles matching across this layered capital structure. Permissionless market creation is open to any wallet at no cost, with creators earning 50% of all trading fees generated on their markets as transactions occur. Professional market maker liquidity pool infrastructure is listed on the project roadmap, indicating plans to deepen the order-book layer beyond the current baseline. Worm launched on Solana in October 2025 following a $4.5 million pre-seed raise, and has since expanded with WormCup, a Telegram Mini App for World Cup prediction markets.

Archer Exchange is a fully on-chain spot orderbook DEX on Solana that replaces the continuous limit order book (CLOB) model with dual flow batch auctions (DFBA). Rather than executing trades on first-come-first-served time-priority, Archer accumulates orders over short fixed batch windows and clears them at a single uniform price — eliminating the latency arms race that benefits high-frequency traders at the expense of ordinary participants. The DFBA mechanism separates maker and taker order flows, running two simultaneous auctions per batch: maker buys against taker sells, and maker sells against taker buys. Every participant in a batch receives the same clearing price regardless of when their order arrived within the window, making sandwich attacks structurally impossible and reducing adverse selection for market makers. Messari began formally tracking Archer as one of two fully on-chain orderbook DEXs on Solana in July 2026.

Excoino was a centralized cryptocurrency exchange founded in 2017 in Tehran, Iran, offering spot trading, P2P exchange, and OTC services across more than 400 cryptocurrencies including SOL, BTC, ETH, and USDT. The platform was operated by Tofad, a subsidiary of Ernica Holding, and served over one million Iranian users before becoming inaccessible in March 2026. The exchange held a knowledge-based license from Iran's Vice Presidency for Science and Technology, though the Central Bank of Iran noted it lacked an official financial services license. Excoino is now defunct with no recovery timeline announced, and thousands of users whose funds were frozen pursued legal remedies following the platform's closure.

OK Exchange is a centralized order-book exchange serving Persian-speaking users in Iran, offering spot and futures trading across 700+ cryptocurrencies including Bitcoin, Ethereum, Solana, USDT, DOGE, XRP, and Tron. Founded in 2017 and operating continuously since, the platform matches buy and sell orders on internal order books with trading pairs denominated primarily in USDT and Iranian Rial. Maker fees are set at 0.1% and taker fees at 0.11%, placing it competitively against both regional peers and global exchanges. Beyond retail spot markets, OK Exchange supports leveraged futures trading with positions of up to 150x on supported assets, targeting experienced traders who require exposure beyond spot prices. A REST API and WebSocket data feeds allow developers to build automated trading systems, retrieve real-time market data, and manage accounts programmatically, with ready-made SDK libraries lowering the barrier to integration. This combination of order-book depth, futures capability, and developer tooling positions OK Exchange as one of the more fully featured domestic trading venues available to Iranian retail and technical users alike.

Xyra Labs distinguishes itself within decentralized trading through its fully on-chain Central Limit Order Book model, bringing an execution paradigm typically reserved for centralized exchanges into the Solana-adjacent DeFi landscape. Xyra Perps matches buyers and sellers directly via a live order book rather than relying on price oracles or pooled liquidity, resulting in tighter spreads and more predictable fills that rival the trading experience on major centralized venues. The platform also offers Hedge Mode — simultaneous long and short positions on the same asset — a function rarely available in decentralized settings and one that appeals to sophisticated traders managing complex position structures. Launched in Q2 2025, the CLOB-based perpetuals platform surpassed $2 billion in cumulative trading volume by year-end 2025, with over 12,000 unique users and peak daily activity of 175,000 trades. The order book infrastructure operates across multiple chains, with Xyra Perps V2 planned to extend multi-chain trading capabilities further with a redesigned interface and copy trading features. An independent audit by Movebit, a security firm focused on multi-chain and Move-VM protocols, has reviewed the core order book and smart contract infrastructure.

Hodl Hodl is a non-custodial peer-to-peer Bitcoin exchange built around an order-book model where sellers post offers specifying price, payment method, and acceptable currencies, and buyers fill those offers directly. Every trade is secured by a 2-of-3 multisig escrow—the platform holds one key but cannot move funds without a co-signature from a trading party. The exchange supports more than 100 payment methods including bank transfers, digital wallets, mobile money, and in-person cash, and accepts more than 100 fiat currencies. Since its founding in 2016, the platform has processed more than 100,000 completed deals across 300,000 registered users. No identity documents or account registration are required to trade beyond an email address and a payment password. The standard fee is 0.75 percent per party, reduced to 0.5 percent for referred users, and is collected only on successfully completed contracts. In May 2026, Hodl Hodl added Lightning Network settlement through an ArkadeOS integration, enabling near-instant finality for users who opt into the Lightning trading path. Broad payment coverage and no-KYC access have made the platform particularly active in markets with limited formal financial infrastructure, including sub-Saharan Africa and Southeast Asia.

BTSE operates a centralized order book exchange that consolidates spot trading across 150+ digital assets and 300+ trading pairs into a unified interface called the All-in-One Order Book. Solana (SOL) is one of the platform's three featured assets alongside Bitcoin and Ethereum, with a direct SOL/USD spot pair available for retail and institutional traders globally outside the United States and Canada. The exchange's matching engine is rated to handle one million orders per second, supporting professional-grade execution for active traders. Standard spot maker/taker fees begin at 0.20%, which can be progressively reduced—and eventually inverted into a maker rebate—through the BTSE token staking program. The platform reported $211 million in 24-hour trading volume and operates continuously since its September 2018 launch, serving a global user base across more than 210 countries.

ZebPay operates a centralized order book exchange supporting 400+ cryptocurrency pairs, including SOL and Solana-ecosystem tokens. Users can place limit orders and stop-loss orders while using real-time charting tools to manage spot trades across major assets. The platform's order book infrastructure also underpins OTC services for institutional clients requiring large off-book trade execution. For retail users in India and Australia, ZebPay's order book provides a regulated trading environment with SOL available alongside major Layer-1 assets such as Bitcoin, Ethereum, BNB, and XRP. The exchange holds formal regulatory registrations with India's Financial Intelligence Unit and Australia's AUSTRAC, making it one of the few compliant order book venues in these two fast-growing markets. Its mobile-first iOS and Android interface allows live order management without relying on desktop trading software.

Blynex is a centralized exchange built around a high-speed matching engine designed for low-latency order execution across spot markets. The platform supports over 300 trading pairs spanning crypto, forex, equities, commodities, and indices, consolidating what would otherwise require multiple specialized accounts into a single interface. SOL/USDT is actively listed with daily volume in the $500,000 range, providing traders seeking Solana exposure a familiar orderbook-based structure within a custodial venue. The exchange reports daily spot volume of $30-40 million and is ranked within the top 100 globally by volume on CoinMarketCap. Bitcoin, Ethereum, XRP, and BNB figure among the highest-volume pairs on the platform. Blynex targets retail participants across 170 countries who prefer the depth and price discovery of a centralized orderbook over non-custodial alternatives.
