Matcha

Matcha is the consumer-facing trading interface built by 0x Labs, the team behind the 0x Protocol that has been routing trades across Ethereum decentralized exchanges since 2017. Launched in March 2020, Matcha functions as a DEX aggregator: rather than routing every swap through a single exchange, it queries over 130 liquidity sources simultaneously — AMMs, order books, RFQ systems — then splits and routes the trade across whichever combination yields the best net price after fees, slippage, and gas. As of April 2025, the platform had facilitated more than $62 billion in trading volume across 6.5 million trades.

Core Technology

The routing engine powering Matcha is the 0x Argon router, introduced with the 0x v2 upgrade in July 2024. Argon combines multiplex routing with multi-hop functionality: a single swap can be divided across multiple venues in parallel, and each leg can pass through intermediate tokens before reaching the destination asset. This means a trade from DAI to WBTC, for example, might split into several paths, some routing through USDC or ETH as an intermediate step, if the combined route beats a direct swap. 0x Labs has benchmarked Matcha as offering the best swap price 93% of the time across trade sizes from $5,000 to $10,000,000+.

Matcha also shows users the actual amount they will receive in their wallet — accounting for network fees, slippage, and other on-chain variables — rather than an idealized pre-fee figure. This is a deliberate design choice: the quoted price is the price you get.

Solana and Cross-Chain Support

Matcha expanded to Solana in April 2025, making it one of the first DEX aggregators to support trades across both SVM and EVM-compatible chains through a single interface. Users can connect Solana and EVM wallets simultaneously. The platform supports cross-chain swaps between Solana and any of the 13+ EVM chains it already covered — Ethereum, Base, Arbitrum, OP Mainnet, Polygon, BNB Chain, Avalanche, Unichain, and others.

Since the Solana launch, Matcha has also extended to newer networks including Monad (an EVM-compatible parallel execution chain) and Plasma, a high-throughput EVM Layer 1 designed for stablecoins. Both integrations launched with gasless trading active from day one.

Total supported chains now stands at 17, with access to more than 9 million tokens.

Features

Matcha Auto and Gasless Trading

Matcha Auto is the platform's default swap mode. It submits orders through the 0x Gasless API, which acts as a relayer and pays gas upfront, deducting the fee from the output token rather than requiring the user to hold a native gas balance. This lets traders on Solana, Monad, Plasma, and other supported chains execute swaps without holding the chain's native token for gas. Auto mode also provides MEV protection and roughly doubles the odds of next-block inclusion compared to standard submission.

Limit Orders

Matcha supports gas-free limit orders. Users set a target price and the order executes automatically when the market reaches it, with no upfront gas required. Market orders and limit orders are both available across all supported chains.

Permit2 Security

Since the 0x v2 upgrade, Matcha uses Permit2 for token approvals, issuing one-time allowances per swap rather than the unlimited approvals that older DeFi interfaces used by default. Unlimited approvals had historically exposed accumulated capital to risk if a contract was later exploited. One-time approvals eliminate that surface.

Token Security and Rug Pull Detection

Matcha includes several features designed to surface token risk before a swap confirms. The Security Audit feature flags contract vulnerabilities — including honeypot mechanics — using data from Go+ Security. A Liquidity Score metric measures how much of a token's supply can be sold with less than 2.5% price impact, giving traders a quantitative sense of exit liquidity before they enter a position. Additional market stats shown per token include issuance date, holder count, and tax information.

These tools are particularly relevant on Solana. According to validation data cited at the time of Matcha's Solana launch, 66% of Solana-based tokens have been identified as malicious. Matcha's risk scoring and audit warnings apply to Solana tokens, with the Liquidity Score in active development for the chain at launch.

Liquidity and Professional Trading

Beyond retail-sized swaps, Matcha sources institutional liquidity through a Request for Quote (RFQ) system. RFQ connects large trades directly with professional market makers, who can provide zero-slippage fills at firm quotes that are not available on open AMM pools. The system activates automatically for trades above certain size thresholds, so the same interface serves both smaller retail swaps and large block trades without requiring the user to select a mode.

Liquidity coverage on the major EVM chains reached 97% on Base, 98% on Ethereum, and 99% on Arbitrum One and Optimism at the time of the 0x v2 launch.

Fees and Governance

Matcha charges no platform fee on most swaps. The 0x Protocol and the broader ecosystem are governed by the ZRX token.

0x Labs Background

0x Labs developed and maintains both the 0x Protocol and Matcha. The 0x Protocol has operated as DeFi infrastructure since 2017, and Matcha was launched in 2020 as its consumer product — a front-end designed for traders who want the best execution without building their own routing logic. The protocol powers a range of applications beyond Matcha itself, and the Argon router introduced in v2 is available to any developer building on top of 0x.

Matcha's addition of Solana support in 2025 marked a meaningful step in the platform's evolution from an EVM-focused aggregator into a genuinely multi-chain interface. The ability to hold Solana and EVM positions through one connected session, route cross-chain swaps, and access Solana token security data within the same interface reflects the aggregator's current positioning as a unified entry point for on-chain trading across ecosystems.
