Stableswap NG

Permissionless deployment of Curve Stableswap plain and metapools. Supports up to 8 coins for plain pools and 2 coins for metapools. Supports: rate-oraclised tokens (e.g. wstETH), ERC4626 (sDAI), rebasing (stETH), and plain (WETH:stETH) pools. Does not support native tokens.

For integrators: check exchange_received. That should improve your pathing significantly. Be aware that if a pool contains rebasing tokens, this method is intentionally disabled.

Overview

The metapool factory has several core components:

• Factory is the main contract used to deploy new metapools. It also acts a registry for finding the deployed pools and querying information about them.
• New pools are deployed via blueprints. The implementation contract targeted by the proxy is determined according to the base pool.

See the documentation for more detailed information.
