Bundle Actions

post

https://svc.blockdaemon.com/defi/v1/lendborrow/bundleactions

Combine multiple lending and borrowing operations into one atomic blockchain transaction. This endpoint bundles several protocol actions—each defined by its specific call data—so that they all execute together (or not at all). The approach improves gas efficiency and minimizes the risk of partial execution, making it ideal for complex, multi-step transactions.

Body Params

The request body for a /defi/v1/lendborrow/bundleactions

lendborrowId

string

enum

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

Allowed:

actions

string

required

An array of strings, where each string represents a specific lending or borrowing operation to execute.

data

string

required

An array containing the encoded call data payloads corresponding to each action listed in the actions array. Each payload includes the parameters necessary for its respective operation.

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.

market

string

Defines the market or asset standard (e.g., USDC or WETH) to be used in the transaction. If not provided, the default market is set to USDC.

enableFee

boolean

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

simulate

boolean

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