Contract Map

Start with Ring Swap unless your integration explicitly targets Uniswap v4.

Native Ring contracts

Component	Responsibility	Use it for
FewFactory	Resolves the canonical FewToken for an original ERC-20	Wrapper discovery and validation
FewToken	Wraps an original asset for use in Ring systems	Manual wrapping and unwrapping
Ring Swap Factory	Creates and indexes Ring Swap pairs	Pair discovery and validation
Ring Swap Pair	Holds two FewToken reserves and executes swaps	Reserve reads, LP accounting, and direct pair integrations
Ring Swap Router	Coordinates normal swap and liquidity flows	Smart contract integrations
Universal Router	Executes command-based routes across supported paths	Interface and advanced routing flows
Permit2	Provides shared allowance and signature-transfer flows	Router approvals

Use Contract Deployments for network-specific addresses and Pools by Network for published pair addresses.

External integration contracts

The Uniswap v4 Integration section covers PoolManager, PositionManager, hooks, and related contracts used in Uniswap v4 environments. These contracts are not a separate native Ring AMM.

Choose the correct entry point

Task	Entry point
Resolve a FewToken	FewFactory
Find or validate a Ring Swap pair	Ring Swap Factory
Execute a standard swap	Ring Swap Router or Universal Router
Provide Ring Swap liquidity	Ring Swap Router
Build a TypeScript route	Ring Swap SDK
Request executable calldata	Routing API
Build a Few hook or use a Uniswap v4 pool	Uniswap v4 Integration

Do not select a contract from its name alone. Select the network and workflow first, then use the official address published for that path.
