Circle CLI gives developers and AI agents a unified interface for onchain operations. Create and manage wallets, transfer, swap, and bridge USDC across blockchains, execute smart contracts, and discover or pay for services. All through a single command interface, without integrating multiple APIs and SDKs. Use Circle CLI to access:
  • Agent Wallets: Wallets with email OTP authentication, full onchain capabilities, and customizable policy enforcement.
  • Local wallets: Self-custodial wallets imported from a private key or mnemonic, stored using the Open Wallet Standard.
  • Circle products: CCTP for USDC bridging and Gateway for x402 nanopayments.

​
