Contracts Overview

If you are new to Ring, the contracts documentation should be read in this order:

1. Ring Swap (v2)
2. FewToken Wrapping
3. Uniswap v4 Integration

How Ring's contract stack is organized

Ring's public contract stack is organized around a native swap product and the FEW asset layer behind it.

• Ring Swap (v2) is Ring's native AMM and router product line.
• FewToken Wrapping covers the FewFactory/FewToken layer used inside Ring Swap pools and routes.
• Uniswap v4 Integration documents how FewToken and Few hooks are used in Uniswap v4 environments.

This distinction is important:

• Ring Swap (v2) should remain visible as a top-level Ring product.
• Ring docs should not imply additional native AMM product lines.
• v4-related material in these docs should be understood as integration with Uniswap v4, not as a separate native v4 product line.

Uniswap v4 Integration

Start here if you want to understand how FewToken interacts with Uniswap v4 liquidity and related infrastructure.
