Send USDC ```bash circle-wallet send 0x... 10 --from 0x... ``` ## All Commands ```bash # Setup circle-wallet setup --api-key # Generate and register entity secret circle-wallet configure --api-key --entity-secret # Use existing credentials circle-wallet config # View configuration # Chains circle-wallet chains # List all supported blockchains circle-wallet chains --show-tokens # Show USDC token IDs circle-wallet chains --mainnet # Mainnets only circle-wallet chains --testnet # Testnets only # Wallets circle-wallet create [name] [--chain ] # Create new SCA wallet circle-wallet list # List all wallets with balances circle-wallet balance [wallet-id] # Check balance # Transactions circle-wallet send [--from ] # Auto-detects chain from wallet circle-wallet drip [address] # Get testnet USDC (sandbox only) ``` ## Supported Chains **Mainnets (10):** APTOS, ARB, AVAX, BASE, ETH, MONAD, OP, MATIC, SOL, UNI **Testnets (11):** APTOS-TESTNET, ARB-SEPOLIA, ARC-TESTNET, AVAX-FUJI, BASE-SEPOLIA, ETH-SEPOLIA, MONAD-TESTNET, OP-SEPOLIA, MATIC-AMOY, SOL-DEVNET, UNI-SEPOLIA Use `circle-wallet chains --show-tokens` to see USDC token IDs for each chain. ## Usage Examples ### Multi-Chain Wallets ```bash # Create wallets on different chains (default: ARC-TESTNET for sandbox) circle-wallet create "Arc Wallet" --chain ARC-TESTNET circle-wallet create "Base Wallet" --chain BASE-SEPOLIA circle-wallet create "Polygon Wallet" --chain MATIC-AMOY # Send automatically uses the correct chain for each wallet circle-wallet send 0xRecipient... 5 --from 0xArcWallet... circle-wallet send 0xRecipient... 3 --from 0xPolygonWallet... ``` ### Send Between Wallets ```bash # Create two wallets circle-wallet create "Wallet 1" circle-wallet create "Wallet 2" # Fund first wallet circle-wallet drip # Send from wallet 1 to wallet 2 (using addresses) circle-wallet send 0xWallet2Address... 5 --from 0xWallet1Address... ``` ### Agent Usage ``` User: "Check my wallet balance" Agent: [circle-wallet balance] "You have 42.5 USDC" User: "Send 10 USDC to 0x123..."
