Integrating with Ring Protocol

Ring keeps compatibility with Uniswap v2-style 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 Uniswap-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 currently operates Ring Swap (v2) as its native AMM.

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 Ring 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.
