Crypto wallet operations via the awal CLI — sign in, check balances, send USDC/ETH/POL/SOL, trade tokens, fund the wallet, and use the x402 payment protocol to discover paid services, pay for API calls, monetize an API, or query onchain data. Use whenever the user mentions signing in, login, authentication, wallet status, balance, address, sending money, paying someone, transferring tokens, ENS names, swapping/trading/converting tokens, funding/topping up/onramp, USDC, ETH, POL, SOL, the x402 bazaar, paid APIs, monetizing an endpoint, or querying onchain data on Base.

Sending Tokens

Use the npx awal@2.12.1 send command to transfer tokens from the wallet to any address on Base, Polygon, or Solana.

If the wallet is not authenticated, see references/auth.md.

Command Syntax

npx awal@2.12.1 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 0x hex 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@2.12.1 send 1 0x1234...abcd

# Send $0.50 USDC to an ENS name
npx awal@2.12.1 send 0.50 vitalik.eth

# Send with dollar sign prefix (note the single quotes)
npx awal@2.12.1 send '$5.00' 0x1234...abcd

# Send ETH on Base
npx awal@2.12.1 send 0.01 0x1234...abcd --asset eth

# Send USDC on Polygon
npx awal@2.12.1 send 1 0x1234...abcd --chain polygon

# Send USDC to a Solana address
npx awal@2.12.1 send 1 AxW7...5fGz --chain solana

# Get JSON output
npx awal@2.12.1 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@2.12.1 status to check; see references/auth.md)
  • Wallet must have sufficient balance (npx awal@2.12.1 balance to check; see references/fund.md to top up)

Error Handling

Common errors:

  • "Not authenticated" - See references/auth.md
  • "Insufficient balance" - Check balance with npx awal@2.12.1 balance; see references/fund.md
  • "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 solana when sending SOL
  • "ETH/POL only supported on EVM chains" - ETH on base, POL on polygon

    This skill provides comprehensive crypto wallet functionality and x402 payment integration using Coinbase's 'awal' CLI and associated libraries. It handles authentication, balance tracking, token transfers, and trading while emphasizing strict input validation to prevent command injection. It also guides developers in building and monetizing their own APIs with x402 payments.

Operates a crypto wallet via the `awal` CLI to sign in, check balances, send USDC/ETH/POL/SOL across Base/Polygon/Solana, swap tokens, fund the wallet, and discover or pay for services on the x402 bazaar. Use when the user needs wallet authentication, balance checks, token transfers, trading, onramp, or access to paid APIs that accept x402 payments.

Generated from the current SKILL.md.

What blockchains does this skill support?
Base, Polygon, and Solana. Balance checks and sends work across all three; token swaps are limited to Base and Polygon.
Do I need to authenticate before using the wallet?
Yes, except for x402 bazaar search and details. Run `npx awal@2.10.0 status` first; if not authenticated, read `references/auth.md` to sign in with an OTP code.
What tokens can I send or trade?
The skill explicitly supports USDC, ETH, POL, and SOL. Token swaps are available on Base and Polygon via the trade command.
What is the x402 protocol and how does it work?
x402 is a payment protocol for discovering and calling paid APIs. You can search the x402 bazaar for services, pay USDC automatically to call them, or monetize your own API endpoint so other agents can pay to use it.
Can I query blockchain data directly?
Yes, the skill includes a `query-onchain` reference for querying events, transactions, and blocks on Base using the CDP SQL API.
