Provide instructions on how to build with Arc, Circle's blockchain where USDC is the native gas token. Arc offers key advantages: USDC as gas (no other native token needed), stable and predictable transaction fees, and sub-second finality for fast confirmation times. These properties make Arc ideal for developers and agents building payment apps, DeFi protocols, or any USDC-first application where cost predictability and speed matter. Use skill when Arc or Arc Testnet is mentioned, working with any smart contracts related to Arc, configuring Arc in blockchain projects, bridging USDC to Arc via CCTP, or building USDC-first applications. Triggers: Arc, Arc Testnet, USDC gas, deploy to Arc, Arc chain, stable fees, fast finality.
Build USDC bridging with Circle Bridge Kit SDK and Crosschain Transfer Protocol (CCTP). 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, bridge USDC, crosschain transfer, CCTP, move USDC between chains, @circle-fin/bridge-kit, adapter-viem, adapter-ethers, adapter-solana-kit, forwarding service, bridge routes.
Cross-chain token transfers using Wormhole and CCTP
Build browser or server token bridging across chains with Circle App Kit or standalone Bridge Kit. Bridges USDC across CCTP chains (EVM and Solana) and CCTPx tokens on supported EVM routes, including registry aliases such as wETH, cirBTC, and EURC plus registry-listed token IDs, through the same `kit.bridge()` call. Supports browser wallets, private-key and Circle Wallets adapters, bridge events, transfer speed (FAST/SLOW), Forwarding Service, and recovery. Bridge operations require no kit key. Use when: bridge a token across chains, bridge USDC, bridge a CCTPx token alias or token ID, move tokens between chains, build wallet-connected bridge UIs, configure Viem/Ethers/Solana adapters, or use @circle-fin/bridge-kit, @circle-fin/app-kit, CCTP, CCTPx, forwarding, or bridge routes.
Cross-chain asset transfers via the LayerZero Value Transfer API. Quote, execute, and track bridging of 850 tokens across 170 chains (EVM, Solana, Aptos, TON) using OFT, Stargate, CCTP, and Aori routes. Quote-then-execute workflow with status polling.
