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 non-custodial wallets where end users retain control of their private keys via Circle's user-controlled wallets SDK. Supports Google, Apple, Facebook social login, email OTP, and PIN authentication with MPC-based key management. Triggers on: user-controlled wallets, embedded wallet, social login wallet, email OTP wallet, PIN wallet, w3s-pw-web-sdk, challenge execution, executeChallenge, non-custodial wallet, MPC wallet, userToken, deviceToken.
Advanced call control features including DTMF sending, SIPREC recording, noise suppression, client state, and supervisor controls. This skill provides JavaScript SDK examples.
