Build with Ring

Choose an integration method based on who should discover the route, build the transaction, and submit it.

Method	Best for	Your responsibility	Start here
Smart contracts	Protocols that need Ring Swap inside an onchain workflow	Select the network and router, manage approvals, set limits and deadlines, and test the complete call path	Smart contract quick start
Ring Swap SDK	TypeScript applications and services that build their own quotes and trades	Fetch pool state, construct the route and trade, then submit through the selected router	Ring Swap SDK
Routing API	Approved partners that want a hosted quote with proposed transaction calldata	Authenticate requests, decode and validate the response, simulate it, and submit only an approved transaction	Routing API

Before you build

All three methods use chain-specific addresses. Start with the maintained contract deployments, then use Pools by Network for pool discovery. Verify addresses and contract relationships onchain before use.

Ring Swap routes use FewToken addresses. Resolve and validate wrappers through the published, independently verified FewFactory for the selected chain. Do not rely on a symbol, token list, or third-party pool alone.

Read Security and Risk before building a flow that can move user funds.

If your integration directly targets Uniswap v4 PoolManager, PositionManager, or hooks, use the Uniswap v4 Integration section instead.
