@circlefin/bridge-stablecoin

Build USDC bridging with Circle App Kit or standalone Bridge Kit SDK and Crosschain Transfer Protocol (CCTP). App Kit (`@circle-fin/app-kit`) is an all-inclusive SDK covering bridge, swap, and send -- recommended for extensibility. Bridge Kit (`@circle-fin/bridge-kit`) is a standalone package for bridge-only use cases. Neither requires a kit key for bridge operations. Supports bridging USDC between EVM chains, between EVM chains and Solana, and between any two chains on Circle Wallets (i.e Developer-Controlled Wallets or Programmable wallets). Use when: bridge USDC, setting up Bridge Kit adapters (Viem, Ethers, Solana Kit, Circle Wallets), handling bridge events, collecting custom fees, configuring transfer speed, or using the Forwarding Service. Triggers on: Bridge Kit, App Kit, bridge USDC, crosschain transfer, CCTP, move USDC between chains, @circle-fin/bridge-kit, @circle-fin/app-kit, adapter-viem, adapter-ethers, adapter-solana-kit, forwarding service, bridge routes.
