You must be authenticated to trade.12 13## Confirm wallet is initialized and authed14 15```bash16npx awal@2.0.3 status17```18 19If the wallet is not authenticated, refer to the `authenticate-wallet` skill.20 21## Command Syntax22 23```bash24npx awal@2.0.3 trade <amount> <from> <to> [options]25```26 27## Arguments28 29| Argument | Description                                                            |30| -------- | ---------------------------------------------------------------------- |31| `amount` | Amount to swap (see Amount Formats below)                              |32| `from`   | Source token: alias (usdc, eth, weth) or contract address (0x...)      |33| `to`     | Destination token: alias (usdc, eth, weth) or contract address (0x...) |34 35## Amount Formats36 37The amount can be specified in multiple formats:38 39| Format        | Example                | Description                            |40| ------------- | ---------------------- | -------------------------------------- |41| Dollar prefix | `'$1.00'`, `'$0.50'`  | USD notation (decimals based on token) |42| Decimal       | `1.0`, `0.50`, `0.001` | Human-readable with decimal point      |43| Whole number  | `5`, `100`             | Interpreted as whole tokens            |44| Atomic units  | `500000`               | Large integers treated as atomic units |45 46**Auto-detection**: Large integers without a decimal point are treated as atomic units. For example, `500000` for USDC (6 decimals) = $0.50.47 48**Decimals**: For known tokens (usdc=6, eth=18, weth=18), decimals are automatic. For arbitrary contract addresses, decimals are read from the token contract.49 50## Options51 52| Option               | Description                                   |53| -------------------- | --------------------------------------------- |54| `-c, --chain <name>` | Blockchain network (default: base)            |55| `-s, --slippage <n>` | Slippage tolerance in basis points (100 = 1%) |56| `--json`             | Output result as JSON                         |57 58## Token Aliases59 60| Alias | Token | Decimals | Address                                    |61| ----- | ----- | -------- | ------------------------------------------ |62| usdc  | USDC  | 6        | 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 |63| eth   | ETH   | 18       | 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE |64| weth  | WETH  | 18       | 0x4200000000000000000000000000000000000006 |65 66**IMPORTANT**: Always single-quote amounts that use `$` to prevent bash variable expansion (e.g. `'$1.00'` not `$1.00`).67 68## Input Validation69 70Before constructing the command, validate all user-provided values to prevent shell injection:71 72- **amount**: Must match `^\$?[\d.]+$` (digits, optional decimal point, optional `$` prefix). Reject if it contains spaces, semicolons, pipes, backticks, or other shell metacharacters.73- **from / to**: Must be a known alias (`usdc`, `eth`, `weth`) or a valid `0x` hex address (`^0x[0-9a-fA-F]{40}$`). Reject any other value.74- **slippage**: Must be a positive integer (`^\d+$`).75 76Do not pass unvalidated user input into the command.77 78## Examples79 80```bash81# Swap $1 USDC for ETH (dollar prefix — note the single quotes)82npx awal@2.0.3 trade '$1' usdc eth83 84# Swap 0.50 USDC for ETH (decimal format)85npx awal@2.0.3 trade 0.50 usdc eth86 87# Swap 500000 atomic units of USDC for ETH88npx awal@2.0.3 trade 500000 usdc eth89 90# Swap 0.01 ETH for USDC91npx awal@2.0.3 trade 0.01 eth usdc92 93# Swap with custom slippage (2%)94npx awal@2.0.3 trade '$5' usdc eth --slippage 20095 96# Swap using contract addresses (decimals read from chain)97npx awal@2.0.3 trade 100 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 0x420000000000000000000000000000000000000698 99# Get JSON output100npx awal@2.0.3 trade '$1' usdc eth --json101```102 103## Prerequisites104 105- Must be authenticated (`awal status` to check)106- Wallet must have sufficient balance of the source token107 108## Error Handling109 110Common errors:111 112- "Not authenticated" - Run `awal auth login <email>` first113- "Invalid token" - Use a valid alias (usdc, eth, weth) or 0x address114- "Cannot swap a token to itself" - From and to must be different115- "Swap failed: TRANSFER_FROM_FAILED" - Insufficient balance or approval issue116- "No liquidity" - Try a smaller amount or different token pair117- "Amount has X decimals but token only supports Y" - Too many decimal places
