Builds token swap functionality using Circle's App Kit or standalone Swap Kit SDKs. App Kit is the recommended choice since it bundles swap, bridge, and send in one package, making it easier to extend later. Swap Kit is lighter if you only need swaps and nothing else. Both require a kit key and run server-side only, so you'll configure adapters for Viem (EVM chains), Solana Kit, or Circle Wallets depending on how you manage keys. Supports same-chain swaps across 17 mainnet chains including Ethereum, Base, Arbitrum, and Solana. The skill walks you through a decision guide before generating code since swaps move real funds. Routes through third-party aggregators like LiFi under the hood.
