Kwala manages the full transaction lifecycle when your workflow calls a smart contract function. It handles all calls, submission, retries, and confirmation so your transactions land on-chain reliably. Kwala provides strong guarantees that your transactions will finalize through:

​
Automatic retries

The RetriesUntilSuccess field ensures critical operations complete even when network conditions cause temporary failures. 
actions:
  - Name: critical_transfer
    Type: call
    TargetContract: 0x65b2b850fee0e0c13d956ab5...
    TargetFunction: function execute(address to)
    TargetParams:
      - 0x742d35Cc6e9A5f1e7A0e6FD4C8b2Bc3F5d9E1234
    ChainID: 80002
    RetriesUntilSuccess: 5
Retry behavior:
  • Retries happen automatically on failure
  • A delay is applied between retries
  • Total attempts = 1 (initial) + RetriesUntilSuccess

​
Using dynamic parameters

Reference event data in your transaction parameters using re.event(): 
TargetParams:
  - re.event(0)    # first parameter from triggering event
  - re.event(1)    # second parameter
This enables workflows where the triggering event determines transaction details.
