IDs and Amounts

Chain IDs

--chain, --from, and --to accept:

CAIP-2: eip155:1
Numeric EVM chain ID: 1
Alias: ethereum, base, hyperevm, megaeth, gnosis, taiko, etc.
Solana mainnet alias/CAIP-2: solana or solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp

defi-cli normalizes these to canonical CAIP-2 IDs in output.

Asset inputs accept:

Symbol: USDC
Token address: 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48
CAIP-19: eip155:1/erc20:0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48
Solana CAIP-19: solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp/token:EPjFWdd5AufqSSqeM2qN1xzybapC8G4wEGGkZwyTDt1v

Output always returns canonical CAIP-19 in fields like asset_id, from_asset_id, to_asset_id.

For swap and bridge quotes:

--amount is base units (recommended for automation)
--amount-decimal is human decimal form
for swaps, these map to --type exact-input (default)
for swaps with --type exact-output, use --amount-out or --amount-out-decimal
passing both base+decimal variants for the same side returns a usage error

Output includes both normalized forms:

"trade_type": "exact-input",
"input_amount": {
  "amount_base_units": "1000000",
  "amount_decimal": "1",
  "decimals": 6
}

Symbol parsing depends on the local bootstrap token registry.
On chains without symbol coverage, pass address or CAIP-19 directly.
Solana support is mainnet-only (solana / solana:5eykt4UsFv8P8NJdTREpY1vzqKqZKvdp).
Solana devnet/testnet aliases and custom Solana CAIP-2 references are rejected.
MegaETH bootstrap symbol support currently includes MEGA, WETH, and USDT (USDT resolves to the chain USDT0 contract).
