FewToken Integration

Ring Swap (v2) keeps compatibility with v2-style AMM integration patterns while introducing Few Protocol as a wrapping layer.

Integration Overview​

To integrate Ring Swap (v2) for swap and liquidity flows, replace your existing v2-style integration points with Ring deployments:

  • Ring Swap Factory
  • Ring Swap Pair Init Code
  • Ring Swap Router
  • Universal Router

Key Difference: Few Protocol Wrapping​

Few Protocol wraps original ERC-20 tokens into FewToken.

Ring's native swap system, Ring Swap (v2), uses wrapped assets in pools and routes.

When integrating:

  • quote prices with FewToken addresses
  • construct swap paths with FewToken addresses
  • resolve wrapped token addresses via FewFactory

Important note​

Ring Swap (v2) is a native Ring product line. The v2 label describes the compatible AMM design; it is not part of a public Ring product-version ladder.

If you are integrating with v4-related workflows elsewhere in these docs, that should generally be understood as FewToken integration with Uniswap v4, not as a separate native v4 protocol.

Swap Path Example​

If your intended route is:

[tokenA, USDC, tokenB]

Use this path for Ring Swap:

[fwTokenA, fwUSDC, fwTokenB]

fwTokenX means the FewToken mapped from original token tokenX.
