npx awal@latest trade <amount> <from> <to> [options]
| Argument | Description |
|---|---|
| -------- | ---------------------------------------------------------------------- |
amount | Amount to swap (see Amount Formats below) |
from | Source token: alias (usdc, eth, weth) or contract address (0x...) |
to | Destination token: alias (usdc, eth, weth) or contract address (0x...) |
The amount can be specified in multiple formats:
| Format | Example | Description |
|---|---|---|
| ------------- | ---------------------- | -------------------------------------- |
| Dollar prefix | '$1.00', '$0.50' | USD notation (decimals based on token) |
| Decimal | 1.0, 0.50, 0.001 | Human-readable with decimal point |
| Whole number | 5, 100 | Interpreted as whole tokens |
| Atomic units | 500000 | Large integers treated as atomic units |
Auto-detection: Large integers without a decimal point are treated as atomic units. For example, 500000 for USDC (6 decimals) = $0.50.
Decimals: For known tokens (usdc=6, eth=18, weth=18), decimals are automatic. For arbitrary contract addresses, decimals are read from the token contract.
| Option | Description |
|---|---|
| -------------------- | --------------------------------------------- |
-c, --chain | Blockchain network (default: base) |
-s, --slippage | Slippage tolerance in basis points (100 = 1%) |
--json | Output result as JSON |
| Alias | Token | Decimals | Address |
|---|---|---|---|
| ----- | ----- | -------- | ------------------------------------------ |
| usdc | USDC | 6 | 0x833589fCD6eDb6E08f4c7C32D4f71b54bdA02913 |
| eth | ETH | 18 | 0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE |
| weth | WETH | 18 | 0x4200000000000000000000000000000000000006 |
IMPORTANT: Always single-quote amounts that use $ to prevent bash variable expansion (e.g. '$1.00' not $1.00).
