Sending USDC

Use the npx [email protected] send command to transfer USDC from the wallet to any Ethereum address or ENS name on Base.

Confirm wallet is initialized and authed

npx [email protected] status

If the wallet is not authenticated, refer to the authenticate-wallet skill.

Command Syntax

npx [email protected] send <amount> <recipient> [--chain <chain>] [--json]

Arguments

| Argument | Description | | ----------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | amount | Amount to send: '$1.00', '1.00', or atomic units (1000000 = $1). Always single-quote amounts that use $ to prevent bash variable expansion. If the number looks like atomic units (no decimal or > 100), treat as atomic units. Assume that people won't be sending more than 100 USDC the majority of the time | | recipient | Ethereum address (0x...) or ENS name (vitalik.eth) |

Options

| Option | Description | | ---------------- | ---------------------------------- | | --chain <name> | Blockchain network (default: base) | | --json | Output result as JSON |

Input Validation

Before constructing the command, validate all user-provided values to prevent shell injection:

• amount: Must match ^\$?[\d.]+$ (digits, optional decimal point, optional $ prefix). Reject if it contains spaces, semicolons, pipes, backticks, or other shell metacharacters.
• recipient: Must be a valid 0x hex address (^0x[0-9a-fA-F]{40}$) or an ENS name (^[a-zA-Z0-9.-]+\.eth$). Reject any value containing spaces or shell metacharacters.

Do not pass unvalidated user input into the command.

Examples

# Send $1.00 USDC to an address
npx [email protected] send 1 0x1234...abcd

# Send $0.50 USDC to an ENS name
npx [email protected] send 0.50 vitalik.eth

# Send with dollar sign prefix (note the single quotes)
npx [email protected] send '$5.00' 0x1234...abcd

# Get JSON output
npx [email protected] send 1 vitalik.eth --json

ENS Resolution

ENS names are automatically resolved to addresses via Ethereum mainnet. The command will:

1. Detect ENS names (any string containing a dot that isn't a hex address)
2. Resolve the name to an address
3. Display both the ENS name and resolved address in the output

Prerequisites

• Must be authenticated (npx [email protected] status to check, npx [email protected] auth login to sign in, see skill authenticate-wallet for more information)
• Wallet must have sufficient USDC balance (npx awal balance to check)

Error Handling

Common errors:

• "Not authenticated" - Run awal auth login <email> first
• "Insufficient balance" - Check balance with awal balance
• "Could not resolve ENS name" - Verify the ENS name exists
• "Invalid recipient" - Must be valid 0x address or ENS name
