To claim a submission, a call to the deBridgeGate.claim() method on the destination chain must be crafted using data taken from various sources. Though deSDK already provides a handy method for this, we explain here where to take and how to prepare this data.
  • _debridgeId, _amount, _receiver, _nonce can be taken from the corresponding args of the Sent event,
  • _chainIdFrom is obviously the ID of the origin chain,
  • _signatures is the string with the signatures concatenated without a delimiter (don’t forget to strip hexadecimal prefixes from each but the first); signatures can be pulled from the deBridge API,
  • _autoParams is the encoded SubmissionAutoParamsFrom struct, which is the derivative of the SubmissionAutoParamsTo with nativeSender taken from the Sent event: so you need to decode _autoParamsagainst theSubmissionAutoParamsTostruct, add the fifth element, and encode back against theSubmissionAutoParamsFrom` struct.
This simple diagram shows the flow of the properties; dashed lines indicate the necessity of data decoding/encoding/unpacking/packing, while the straight line shows that the datum should be passed as is: Gathering Data for Claims After all these elements are combined into one single call, you can sign and broadcast your transaction and wait for the Claimed event. This will indicate a successful submission.
