Request body

fromstring required

Blockchain address of the sender. For EVM chains, use a checksummed hex address (e.g., 0xABCDEF...). This address must hold sufficient balance and will sign the transaction.

tokenAddressstring required

Address of the token.

amountstring required

Number of tokens, specified in the token's smallest denomination (base units). Do not send human-readable decimal values. Examples: 1 WETH (18 decimals) = "1000000000000000000"; 1 USDC (6 decimals) = "1000000".

tostring required

Blockchain address of the recipient. For EVM chains, use a checksummed hex address (e.g., 0xABCDEF...).

gasstring

Maximum number of gas units to allocate for the transaction, as an integer string (e.g., '200000'). If omitted, gas is estimated automatically. Note: this is gas units, not wei or gwei.

chainSymbolstring

The abbreviated chain name for queries or transactions.

receiverstring required

Address of the recipient receiving the tokens.

gasPrioritystring

Specifies the priority level for gas fees (e.g., 'low', 'medium', or 'high'), which influences the transaction speed and cost.

enableFeeboolean

Flag to include a basis points fee transaction alongside the main transaction when set to true.

simulateboolean

When true, dry-runs the transaction batch via eth_simulateV1 and returns a simulate field with status and error on each transaction.
