# Deposit with approval

`POST /defi/v1/lendborrow/deposit-with-approval`

## Request

- Base URL: `https://svc.blockdaemon.com`
- URL: `https://svc.blockdaemon.com/defi/v1/lendborrow/deposit-with-approval`
- Auth: API key in header `X-API-Key`

Returns unsigned transactions for ERC-20 approval when allowance is below the deposit amount, plus the protocol deposit transaction. Without batchOption, data is an ordered array [approveTxn?, depositTxn]. With batchOption EIP-5792 or EIP-7702 (supported chains), returns a single batched payload. Same request parameters as Deposit per protocol.

**Compute Unit Value:** `230` (Fixed)

## Request body

- LendborrowDepositWithApprovalRequest: The request body for a /defi/v1/lendborrow/deposit-with-approval
  - `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.
  - `asset` string: Token address of the asset to deposit.
  - `amount` string, 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".
  - `onBehalfOf` string, required: Public address of the user on whose behalf the deposit action will be executed.
  - `from` string, 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.
  - `gas` string: 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.
  - `gasPriority` string: Specifies the priority level for gas fees (e.g., 'low', 'medium', or 'high'), which influences the transaction speed and cost.
  - `enableFee` boolean: 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.
  - `batcherContract` string: 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.
  - `simulate` boolean: When true, dry-runs the transaction batch via eth_simulateV1 and returns a simulate field with status and error on each transaction.
  - `useCustomVaults` boolean: A boolean flag to scope the API request. If true, the request will be processed using the partner's dedicated vaults. If false or omitted, it uses the standard public pools.
  - `to` string: Blockchain address of the recipient. For EVM chains, use a checksummed hex address (e.g., 0xABCDEF...).
  - `market` string: The market of the asset, such as USDC or WETH. Defaults to USDC.
  - `marketId` string: Specifies the market Id of any market in Morpho.
  - `vaultAddress` string: Specifies the vaultAddress of any vault in Morpho.
  - `collateral` boolean: Specifies the condition for depositing the token as a supply to earn the yields only or use it as collateral to borrow loan asset.
