Q3Domain Verified
In the context of "The Complete Cross-Chain Asset Bridge Course 2026: From Zero to Expert!", a bridge implementing a "Lock-and-Mint" mechanism for asset transfer from Chain A to Chain B faces a scenario where the minting contract on Chain B fails to execute due to an out-of-gas error. What is the most likely immediate consequence for the user who initiated the transfer?
The asset on Chain A is immediately burned.
The asset on Chain A is automatically returned to the user's wallet.
The user's transaction on Chain A is reverted, and no asset is locked.
The asset on Chain A remains locked, and the user must retry the transaction on Chain B.
