Motoswap pools are now live on 0x, making Motoswap liquidity available across every app built on 0x. The integration lets 0x integrators reach Motoswap's markets through the existing 0x API without a separate connection, adding another liquidity source to 0x's routing network.
Paxos has tapped 0x to power PAXGy, a yield-bearing tokenized gold asset, from day one of its launch. The move positions 0x as the onchain routing rails for the token, letting integrators surface 'gold that grows' (gold accruing yield) through the 0x API without a separate integration.
0x integrators can now reach Aerodrome's Aero Lite liquidity on the Arc Mainnet — including USDC, EURC, and cirBTC depth — one click away. The move follows Arc's day-one support via 0x's Swap API and Cross-Chain API, extending 0x routing to Arc's tokenized finance ecosystem.
0x analyzed over 84,000 Uniswap v4 hooks and found only 19% to be safe, reiterating that a malicious hook doesn't need a deceptive UI to scam users — it just needs to appear as the best quote. The finding underscores the risk surface of Uniswap v4's hook architecture, where hooks execute custom logic during pool operations.
0x says it will begin using v3 pools on bankr for Arbitrum starting this week to test a new fee structure and new features. The move signals a shift in how 0x routes/constructs liquidity on Arbitrum as it experiments with v3 pool mechanics.
0x is routing trades across Coinbase Tokenized Stocks — including NVDAc, AAPLc, and METAc — from day one of their launch on Base. The stocks are backed and redeemable by Coinbase and are swappable onchain via the 0x API, so integrators can give users access with a single integration.
0x says running its Swap API on @QuickNode cut p90 latency by 70% on Solana, delivering fresher account state and less drift between quote and fill. The move marks the first time the nine-year-old routing API has left the EVM: on Solana there is no ready-to-sign transaction, so each trade is priced and constructed differently than on EVM chains.
0x is hardening its swap infrastructure around the contracts that hold users' token approvals. Its AllowanceHolder contract has been formally verified by @bailsecurity on the Certora Prover, mathematically proving the contract is correct — the same assurance used by Aave and Uniswap. Few other swap aggregators claim this level of verification.
Per the verification, approvals cannot outlive the transaction even against a hostile callee, an allowance is scoped to exactly one (operator, owner, token) and cannot be over-spent, and failed calls roll back atomically. bailsecurity has also confirmed it is currently conducting an audit for 0x, alongside the Immutable Settler contracts and audits by Trail of Bits, OpenZeppelin, Dedaub, and Ouroboros, plus 0x's SOC work, as part of a broader security posture for its swap infrastructure.
Coinbase-wrapped HYPE and ZEC (cbHYPE, cbZEC) are now available through 0x. Integrators building with the 0x Swap API get automatic access to both tokens on day one, with deep liquidity and 0x's routing, targeted at Coinbase-wrapped assets on Base.
0x announced that its SOC 2 Type 1 audit is complete, with the Type 2 audit now underway. The company frames the milestone as independent assurance for teams building on the 0x API, covering the operational controls behind its routing infrastructure.
Will Warren transitioned out of the co-CEO role, remaining as board member and shareholder. Co-founder Amir Bandeali assumed sole CEO leadership, citing the need for faster decision-making in a hyper-competitive market.
The U.S. Commodity Futures Trading Commission charged 0x alongside Opyn and Deridex. ZeroEx settled by paying a $200,000 civil penalty and agreeing to cease the violations.
The round included Pantera, OpenSea, Coinbase, Sound Ventures, and Jared Leto. Funding targeted team expansion and scaling Matcha, 0x Swap API, and the 0x Protocol across seven blockchains.
An on-chain binding governance system was deployed, giving ZRX holders direct control over a treasury seed-funded by 0x Labs. The DAO marked the first major step toward full protocol decentralization.
The equity round included Jump Capital, Blockchain Ventures, and Coinbase Ventures. Funds were earmarked for expanding Matcha globally, the 0x API, and the Periscope Trading desk.
Approved by a vote of 2,362 ZRX holders with 11.6M ZRX, v4 delivered up to 70% gas savings for RFQ liquidity, plug-and-play on-chain liquidity, and automatic upgradability via governance.
0x Labs released Matcha, a consumer-facing DEX aggregator using the 0x API to smart-route orders across multiple on-chain liquidity sources including Uniswap, Curve, and Kyber.
V3 introduced ZRX staking for market makers, protocol fees, and ERC20BridgeProxy contracts enabling aggregated liquidity from Kyber, Uniswap, and Oasis. Approved via on-chain governance vote.
Security researcher samczsun disclosed a flaw that could allow attackers to fill orders with invalid signatures. The v2.0 Exchange contract was immediately shut down; no user funds were lost and a patched contract was deployed.
After over a year of development and multiple security audits, v2 introduced ERC-721 (NFT) support, a modular architecture, and a new order format enabling broader asset exchange use cases.
The token sale ran August 15–16, 2017, raising $24 million in ether from 12,000 backers at $0.048 per ZRX. The protocol's first smart contracts were deployed to Ethereum mainnet simultaneously.
