Module 5 - Understanding executeBatchCallsSameChain function

The BatchTransaction Contract is Designed as a multi-caller Contract capable of Batching multiple Transactions into a Single Call. This Contract allows executing a Series of Operations in one go, significantly Reducing Gas Costs and improving Transaction Efficiency.

The executeBatchCallsSameChain function in the BatchTransaction Contract is Specifically Designed to Call the execute function of Multiple Adapter Contracts whose addresses are provided in the target Parameter. This allows for executing the Core Business Logic of different Adapters in a Single, Batched Transaction.

Function executeBatchCallsSameChain

The executeBatchCallsSameChain function enables the Contract to Interact with multiple Adapter Contracts by invoking their execute functions in a Single Transaction. The Address of each Adapter Contract is passed in the target Parameter, which is used to Specify where the call should be directed.

Function Definition

function executeBatchCallsSameChain(
    address[] calldata tokens,
    uint256[] calldata amounts,
    address[] calldata target,
    uint256[] calldata value,
    uint256[] calldata callType,
    bytes[] calldata data
) external payable {}

Parameters

• tokens (address[] calldata):
  An array of Token Addresses specifying which Tokens should be fetched from the User for each Transaction.

• amounts (uint256[] calldata):
  An array of Amounts corresponding to each Token in the tokens array to be transferred from the User for each Transaction.

• target(address[] calldata):
  An array of Addresses of the Adapter Contracts whose execute function needs to be Called. Each Address corresponds to a specific Adapter Contract where the Business Logic is implemented.

• value (uint256[] calldata):
  An array specifying the Amount of Native Tokens (such as ETH) to be sent along with each Transaction to the respective target Address.

• callType (uint256[] calldata):
  An array that Defines the Type of Call for each Transaction -

  • 1: call - Executes the execute function directly on the Target Adapter Contract.
  • 2: delegatecall - Executes the execute function in the Context of the Calling Contract.

• data (bytes[] calldata):
  An array of bytes Containing the Encoded Data for each execute function call of the Adapter Contracts. This Data is what gets Passed to the execute function of each respective Adapter.

Functionality

• The executeBatchCallsSameChain function Batches Multiple execute function calls into one Transaction, allowing Efficient Interaction with various Adapter Contracts.

• Each entry in the target array represents an Adapter Contract whose execute function will be called with the corresponding encoded Data in the data array.

• This function is highly flexible, supporting both call and delegatecall Operations, allowing for either Direct Execution on the Target Contract or within the Context of the Calling Contract.

• The function handles Token Transfers, Native Token Transfers, and Batch Execution of the execute function on Multiple Adapter Contracts, making it highly efficient for multi-step Operations.
