[svetlio8]

High-level spec link

Description:

• In the app/process/watcher/transfer/watcher.go in the method processTransaction there is if with error message Wrapped to Wrapped transfers currently not supported.
• In the app/process/watcher/evm/watcher.go the method handleBurnLog there is if with error message Wrapped to Wrapped transfers currently not supported.
• Implementation of the logic for Burn and Mint in the handlers.
  • Ex: in the EVM watcher to be called new handler for the burn logic of wrapped to wrapped if the network is EVM (not Hedera == 0) burnEvent.TargetChainId != 0 and IF the burnEvent.TargetChainId == burnEvent.NativeChainId
• Rollback scenario in case of TX fail / network down / etc.
  • Source network burn issue > do not mint on the destination.
  • Destination network mint issue > mint on Source network what was already burned.
• Every validator should sign the transfer.
• ‼️ In case there is no wrapped token on one of the networks > throw an error message. This case should be also handled at the FE.
