swap-tokens

Build token swap functionality with Circle App Kit or standalone Swap Kit SDKs. App Kit (@circle-fin/app-kit) is an all-inclusive SDK covering swap, bridge, and send. Swap Kit (@circle-fin/swap-kit) is standalone for swap-only use cases. Both require a kit key and run server-side only. Swap runs on mainnet chains and on Arc Testnet. Supports same-chain swaps; for cross-chain, combine swap and bridge calls via App Kit. Use when: swapping tokens, exchanging stablecoins, converting USDT to USDC, setting up swap adapters, estimating swap rates, configuring slippage or stop limits, collecting custom swap fees, or combining swap and bridge for cross-chain token movement. Triggers: swap tokens, USDT to USDC, @circle-fin/swap-kit, @circle-fin/app-kit, estimateSwap, slippage, stop limit, kit key.
