Request body

liquidStakingId'1' | '11155111' | '2' | '56' | '97' | '137'

The unique ID to specify the liquid staking protocol for routing staking-related queries or transactions.

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

Token contract address.

spenderstring required

Public address of the spender.

subtractedAmountstring required

Amount to decrease the allowance by, specified in the token's smallest denomination (base units). Examples: 1 WETH (18 decimals) = "1000000000000000000"; 1 USDC (6 decimals) = "1000000".

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.

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.
