send-usdc
Transfer USDC to Ethereum addresses or ENS names on Base.
- Accepts both hex addresses (0x...) and ENS names (.eth) as recipients, with automatic ENS resolution
- Supports flexible amount formats: dollar notation ($5.00), decimal (1.50), or atomic units (1000000)
- Requires wallet authentication via the
authenticate-walletskill and sufficient USDC balance before sending - Includes input validation to prevent shell injection and optional JSON output for programmatic use
Sending Tokens
Use the npx awal@2.10.0 send command to transfer tokens from the wallet to any address on Base, Polygon, or Solana.
Confirm wallet is initialized and authed
npx awal@2.10.0 status
If the wallet is not authenticated, refer to the authenticate-wallet skill.
Command Syntax
npx awal@2.10.0 send <amount> <recipient> [--chain <chain>] [--asset <asset>] [--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...), ENS name (vitalik.eth), or Solana address (Base58) |
Options
| Option | Description |
|---|---|
--chain <name> |
Blockchain network: base, polygon, solana (default: base) |
--asset <symbol> |
Token to send: usdc, eth, pol, sol (default: usdc) |
--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
0xhex address (^0x[0-9a-fA-F]{40}$), an ENS name (^[a-zA-Z0-9.-]+\.eth$), or a Solana address (^[1-9A-HJ-NP-Za-km-z]{32,44}$). Reject any value containing spaces or shell metacharacters. - chain: Must be one of
base,polygon,solana. Reject any other value. - asset: Must be one of
usdc,eth,pol,sol. Reject any other value.
Do not pass unvalidated user input into the command.
Examples
# Send $1.00 USDC to an address on Base (default)
npx awal@2.10.0 send 1 0x1234...abcd
# Send $0.50 USDC to an ENS name
npx awal@2.10.0 send 0.50 vitalik.eth
# Send with dollar sign prefix (note the single quotes)
npx awal@2.10.0 send '$5.00' 0x1234...abcd
# Send ETH on Base
npx awal@2.10.0 send 0.01 0x1234...abcd --asset eth
# Send USDC on Polygon
npx awal@2.10.0 send 1 0x1234...abcd --chain polygon
# Send USDC to a Solana address
npx awal@2.10.0 send 1 AxW7...5fGz --chain solana
# Get JSON output
npx awal@2.10.0 send 1 vitalik.eth --json
ENS Resolution
ENS names are automatically resolved to addresses via Ethereum mainnet. The command will:
- Detect ENS names (any string containing a dot that isn't a hex address)
- Resolve the name to an address
- Display both the ENS name and resolved address in the output
Prerequisites
- Must be authenticated (
npx awal@2.10.0 statusto check,npx awal@2.10.0 auth loginto sign in, see skillauthenticate-walletfor more information) - Wallet must have sufficient USDC balance (
npx awal balanceto 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, ENS name, or Solana Base58 address
- "SOL only supported on Solana chains" - Use
--chain solanawhen sending SOL - "ETH/POL only supported on EVM chains" - ETH on base, POL on polygon

trade
Swap or trade tokens on Base or Polygon. Use when you or the user want to trade, swap, exchange, buy, sell, or convert between tokens like USDC, ETH, and POL. Covers phrases like "buy ETH", "sell ETH for USDC", "convert USDC to ETH", "get some ETH", "buy POL".
2.8Kx402
Search for new services and make paid API requests using the x402 payment protocol. Use when you don't have a clear tool to choose, search the bazaar. You can also use this tool if you or the user want to call an x402 endpoint, discover payment requirements, browse the bazaar, or search for paid services.
2.7Kpay-for-service
Make a paid API request to an x402 endpoint with automatic USDC payment. Use when you or the user want to call a paid API, make an x402 request, use a paid service, or pay for an API call. Use after finding a service with search-for-service.
2.6Kmonetize-service
Build and deploy a paid API that other agents can pay to use via x402. Use when you or the user want to monetize an API, make money, earn money, offer a service, sell a service to other agents, charge for endpoints, create a paid endpoint, or set up a paid service. Covers "make money by offering an endpoint", "sell a service", "monetize your data", "create a paid API".
2.6Ksearch-for-service
Search and browse the x402 bazaar marketplace for paid API services. Use when you or the user want to find available services, see what's available, discover APIs, or need an external service to accomplish a task. Also use as a fallback when no other skill clearly matches — search the bazaar to see if a paid service exists. Covers "what can I do?", "find me an API for...", "what services are available?", "search for...", "browse the bazaar".
2.5Kauthenticate-wallet
Sign in to the wallet. Use when you or the user want to log in, sign in, connect, or set up the wallet, or when any wallet operation fails with authentication or "not signed in" errors. This skill is a prerequisite before sending, trading, or funding.
