OK Exchange

OK Exchange is a centralized cryptocurrency exchange (CEX) based in Iran, operating at ok-ex.io. Founded in 2017 by three web programming enthusiasts under Amatis Company, the platform was built to serve Persian-speaking users seeking access to digital asset markets in a region where international exchanges are largely unavailable due to sanctions. Over roughly eight years of operation, OK Exchange has grown into one of the more established local crypto trading venues in the Iranian market, listing over 700 cryptocurrencies and tokens.

How It Works

OK Exchange operates as a standard centralized exchange: users register, complete identity verification (KYC), deposit Iranian Rial or supported digital assets, and trade via the platform's web or mobile interfaces. The exchange holds user funds in its custody system, matching buy and sell orders on its internal order books for spot markets, or executing instant swaps through its quick-exchange (OTC) desk.

Beyond the basic trading interface, OK Exchange offers a REST API and WebSocket data feeds, enabling developers to build automated trading systems, retrieve real-time market data, and manage accounts programmatically. Ready-made SDK libraries are available for popular programming languages, lowering the barrier to integration for technical users.

Core Product Suite

Spot Trading is the exchange's primary offering, covering a broad selection of cryptocurrencies including Bitcoin (BTC), Ethereum (ETH), Tether (USDT), Solana (SOL), DOGE, XRP, Tron (TRX), and hundreds of altcoins and tokens. Pairs are denominated primarily in USDT and Iranian Rial.

Futures Trading allows users to take leveraged positions of up to 150x on supported assets. This product targets more experienced traders seeking exposure beyond spot prices.

Quick Exchange (Fast Swap) provides an OTC-style instant conversion service for a curated set of major cryptocurrencies. Users can buy or sell without manually placing limit or market orders, making it accessible for less experienced traders.

Built-in Wallet integrates directly with user accounts, supporting deposits and withdrawals across multiple blockchain networks. OK Exchange supports assets on Bitcoin, Ethereum, Tron, Solana, and additional networks, allowing users to send and receive funds on-chain.

Treasure Island is a gamified yield feature that enables automatic earnings when users maintain minimum balances of $10 per cryptocurrency. The mechanism resembles a savings or staking product, though the underlying yield source is not detailed in public documentation.

Fees and Accessibility

Trading fees are set at 0.1% for maker orders and 0.11% for taker orders, which are competitive with regional and global peers. The platform claims zero withdrawal fees for fiat conversions involving Iranian Rial, reducing friction for local users moving between crypto and their national currency.

Mobile applications are available for both iOS and Android, complementing the web interface. Customer support operates around the clock in Persian, reflecting the platform's primary audience.

Solana Integration

OK Exchange lists Solana (SOL) in its quick-exchange section alongside Bitcoin, Ethereum, and other major assets, and publishes daily price updates for SOL through its Telegram channel and blog. The exchange supports on-chain SOL deposits and withdrawals, meaning users can transact directly on the Solana network. OK Exchange does not operate Solana-native programs or on-chain smart contracts; its connection to Solana is as a supported network for asset custody and trading, similar to how it supports Bitcoin and Ethereum alongside other chains.

Team and History

According to the company's own statements, OK Exchange was founded in 2017 by three individuals with backgrounds in web programming, incorporated under Amatis Company. The founders' names are not disclosed in public-facing materials. The exchange claims over eight years of continuous operation, which, given the hostile regulatory environment Iranian crypto businesses face internationally, represents a meaningful track record for a local platform.

Security and Compliance

OK Exchange states it requires KYC identity verification for all users. Security measures cited include two-factor authentication (2FA) and encrypted wallet infrastructure. The platform positions itself as compliant with Iranian financial regulations, which is a distinct compliance context from international exchange standards — Iranian users face a legal patchwork that differs significantly from Western regulatory frameworks.

There are no third-party security audits or proof-of-reserves attestations disclosed in publicly accessible documentation. Potential users should evaluate custodial risk accordingly, particularly given Iran's isolation from global financial infrastructure.

Asset Listings

The platform lists 700+ cryptocurrencies. Its blog and Telegram channel regularly announce new listings and delistings as part of periodic review processes. Recent additions have included smaller-cap altcoins such as ANSEM, VSN, ALLO, ZAMA, and BANK to the quick-exchange section, while periodic delistings have removed assets like MUBI, AERGO, and SWEAT based on liquidity or activity reviews.

Positioning

OK Exchange serves a market niche that few international exchanges can reach: Iranian retail investors and traders who cannot access global platforms such as Binance, OKX, or Coinbase due to sanctions-based restrictions. The platform's Persian-language interface, Rial on-ramp and off-ramp capabilities, and local customer support make it functionally distinct from global CEXs even where the underlying trading mechanics are similar.

Its developer API suite suggests ambitions beyond a pure retail audience, positioning it partly as infrastructure for domestic Iranian fintech applications and automated trading operations. The Treasure Island yield feature indicates some effort to compete on holding incentives beyond pure trading volume.
