🚀 New Features

  • Buy/Sell Tax Support: Added support for Fee-on-Transfer tokens, which are subject to buy/sell taxes. Previously, users needed to adjust slippage tolerance manually to account for these taxes, often leading to errors. With the new fee-on-transfer accounting, slippage tolerance adjustments are no longer necessary. Additionally, the buy and sell tax are now returned, allowing users to utilize this information as needed.
  • Smart Contract Wallet Support: Added support for Smart Contract Wallets in Swap API v2’s Permit2 flow.
  • Gas Optimization: Implemented gas optimizations for Solidly V3 integration.
  • Routing Improvements: Significantly improved routing for amphrETH and sDOLA.

🌊 New Liquidity Sources

  • Arbitrum: Enabled RFQ on Arbitrum in Swap API v2.
  • Base: Added SoSwap and Kinetix as new liquidity sources on Base. Also enabled RFQ on Base in Swap API v2.
