Few Protocol

Few Protocol is the core asset layer of Ring.

It wraps original ERC-20 assets into FewToken, which are then used across Ring products and external integrations.

Why Few exists​

The purpose of Few Protocol is to expand usable liquidity and improve capital efficiency.

In practice, Ring uses Few so that:

  • liquidity can be organized around wrapped assets
  • trading systems can work with FewToken instead of only original ERC-20 assets
  • Ring can compete more effectively in routing, quoting, and execution

Where Few is used today​

Today, FewToken is used in two main places:

  1. Ring Swap (v2), which is Ring's native AMM and routing system
  2. Uniswap v4 liquidity environments, where FewToken can also be deployed through integration flows

Important distinction​

Few is the core Ring mechanism.

But Few should not be confused with a separate "Ring v4" protocol.

  • Ring's native swap protocol is Ring Swap (v2)
  • v4-related documentation in the current stack refers to FewToken integration with Uniswap v4

In this section​

This section covers:

  • how to integrate with Few-based token wrapping
  • how to resolve FewToken addresses
  • how to map FewToken back to underlying ERC-20 assets
  • deployment information for Few-related contracts
