I would like to request the addition of support for the Canto blockchain in the 0x Swap and Price API. Canto is a permissionless, general-purpose blockchain running the EVM. It was specifically designed to fulfil the promise of decentralized finance (DeFi) by creating new systems that are accessible, transparent, decentralized, and free. Key Features: Uniswap V2 DEX: Canto has a robust DEX built on the Uniswap V2 protocol, which is widely recognised and trusted in the DeFi community. Solidly for Stable Pairs: For stable pairs, Canto integrates Solidly, providing efficient and reliable trading mechanisms for stable assets. Ambient Pools: The Canto ecosystem also supports ambient pools, further enhancing liquidity and trading efficiency across various asset pairs.
