- We are proud to be launching support for Swap API on Polygon alongside our initial partners Matcha, DexGuru, DexKit, Dodo, MyCrypto.com, Set Protocol, Zapper and Zerion.
- Check out our documentation and start building on Polygon with Swap API today!
The 0x Swap API is designed to make it easy for DeFi developers to tap into DEX liquidity in a fast, reliable, and easy to use way so you can focus on what matters: your product. Since launch, Swap API has facilitated over 1.5M trades from nearly 300K unique traders that in total represent more than $27 billion in volume traded across Ethereum and Binance Smart Chain.
Swap API powers the top DeFi teams on both Ethereum and Binance Smart Chain, and today we are incredibly excited to continue expanding the reach of our product by bringing the experience our integrators know and love to developers building on Polygon. With this, we want to help our integrators and the Polygon developer ecosystem onboard the next 1,000,000 users to crypto.
Why Polygon?
0x Labs’ mission is to create a tokenized world where all value can flow freely. We believe that exposing the broadest set of users to smart contracts, self-custody wallets, and DEX markets is key to achieving that mission.
We shared our framework for evaluating new networks in October 2020 and our phased approach for rolling out support in other Layer 1 and L2 networks back in February this year. Given the role of 0x protocol as a middleware protocol that sits in between the blockchain consensus layer and the application layer that’s exposed to end users, the needs of users and integrators weigh heavily in the evaluation.
Polygon has demonstrated significant growth a. Over the past 3 months, Polygon has developed a vibrant ecosystem. Earlier this month it processed almost 3X as many transactions as Ethereum and today 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 launch Swap API support for Polygon alongside our initial launch partners Matcha, DexGuru, DexKit, Dodo, MyCrypto.com, Set Protocol, Zapper and Zerion.
We are excited about this step in our mission to create a tokenized world where all value can flow freely, and we have a lot more coming! In the coming weeks we will continue adding support for more L1 chains and L2 solutions and we look forward to working with more teams that want to help their users explore decentralized exchange in this growing multichain world.
Start building on Polygon with 0x Swap API
If you are looking to add Polygon trading to your product, Swap API is the best place to start. Swap API currently aggregates all existing liquidity sources on Polygon — including QuickSwap, SushiSwap, Curve, Dodo, mStable, Dfyn, Cometh and more.
You can find our updated docs here. If you are familiar with Swap API /swap on Ethereum or BSC, you will notice the integration process is very similar. Here’s an example quote request.
Support for 0x RFQ and open order book orders is not yet available, but it is coming in our next iteration of Swap API on Polygon. Stay tuned!
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.
