Request body

lendborrowId'1000' | '1003' | '1005' | '1200' | '1208' | '1203' | '1204' | '1205' | '1206' | '1207' | '1100' | '1300' | '1302' | '1400' | '1401' | '1402' | '1403' | '1404'

The unique ID to specify the lending and borrowing protocol for routing relevant queries or transactions.

assetstring required

Token address of the asset to repay.

interestRateModestring required

Interest rate mode as defined by Aave. Default is 1.

onBehalfOfstring required

Public address of the user on whose behalf the repay action will be executed.

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.

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.

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".

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.

batchOption'EIP-5792' | 'EIP-7702'

Transaction batching standard to use. Supported values: 'EIP-5792' (wallet-level batching via wallet_sendCalls) or 'EIP-7702' (EOA code delegation via batcherContract). Requires batcherContract when using EIP-7702.

batcherContractstring

The EOA address of the batcher that will be used to execute the transaction when using EIP-7702 batching. If not provided, the default batcher contract for the chain will be used.

simulateboolean

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

marketstring

The market of the asset, such as USDC or WETH. Defaults to USDC.

marketIdstring required

Specifies the market Id of any market in Morpho.
