Sending USDC

Use the npx awal@2.0.3 send command to transfer USDC from the wallet to any Ethereum address or ENS name on Base.

Confirm wallet is initialized and authed

npx awal@2.0.3 status

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

Command Syntax

npx awal@2.0.3 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 awal@2.0.3 send 1 0x1234...abcd

# Send $0.50 USDC to an ENS name
npx awal@2.0.3 send 0.50 vitalik.eth

# Send with dollar sign prefix (note the single quotes)
npx awal@2.0.3 send '$5.00' 0x1234...abcd

# Get JSON output
npx awal@2.0.3 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 awal@2.0.3 status to check, npx awal@2.0.3 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
