- 0x Swap API is live on Optimism, aggregating liquidity across Uniswap and Synapse
- Initial integration partners include Matcha, DexGuru, DexKit, Mean Finance, Metric Exchange, Coinbase Wallet, Set Protocol, Zapper, and Zerion
- Check out our documentation and start building on Optimism with Swap API today!
0x Swap API lets developers easily and reliably tap into aggregated, multi-chain DEX liquidity so they can focus on what matters: their product. It powers a growing list of top DeFi apps on Ethereum, Binance Smart Chain, Polygon, Avalanche, Fantom, and Celo. Today, we are bringing the industry-leading liquidity API to the Optimism ecosystem!
While Ethereum is the platform on which most tokenized value has emerged in the past few years, transactions have become prohibitively expensive, pricing out potential users and use cases. Optimism, an EVM compatible optimistic rollup chain, aims to increase the throughput of the Ethereum network and reduce gas costs. By improving scalability, optimistic rollups make it cheaper and easier for users to transact on top of Ethereum. Optimism represents an exciting opportunity to expand the reach of 0x Protocol and that of our Swap API partners to a large and growing global user base.
We are proud to be launching support for Swap API on Optimism alongside our initial partners Matcha, DexGuru, DexKit, Mean Finance, Metric Exchange, Coinbase Wallet, Set Protocol, Zapper, and Zerion. We expect many more integrations to follow in the coming weeks!
The role of 0x in a multi-chain world
The 0x mission is to create a tokenized world where all value can flow freely regardless of the blockchain it lives on. We believe that exposing the broadest set of users to smart contracts, self-custody wallets, and DEX markets is critical to driving multi-chain adoption, and we are excited to see what Optimism support on Swap API unlocks.
As core exchange infrastructure for the internet, we will continue to add support for new L1 chains and L2 solutions and help our integrators to onboard the next wave of crypto users to their products.
Start building on Optimism with 0x Swap API
If you are looking to add trading on Optimism to your product, Swap API is the best place to start. Swap API currently aggregates liquidity across Uniswap and Synapse on Optimism. Support for 0x RFQ and open order book orders will be rolled out gradually.
You can find our updated docs here.
If you are familiar with Swap API /swap on Ethereum, BSC, Polygon, Avalanche, Fantom, or Celo, you will notice the integration process is very similar. Here’s an example quote request.
If you are new to building with Swap API, don’t hesitate to reach out on StackExchange for developer support (tag your question with ‘0x’ so we are properly notified). For general inquiries, you can always find us on Discord.
