If the destination chain's node is unreachable, will the ChainBridge relayer be able to retry a deposit?

[waymobetta]

There may be times when one of the networks you are trying to bridge is found to be unreachable. As a result, the relayer- sender of the transaction- will not be able to successfully POST data to that corresponding chain; however, the relayer can be restarted to revisit all blocks from a starting point to determine if the processing required was successful.

Scenario:
Upon successful deposit event, if the destination chain for whatever reason goes offline and cannot accept the corresponding POST request routed from the relayer to say, issue tokens on the destination, the relayer can be restarted in order to retry this processing.

This can be done by setting the startBlock field stored within the relayer's config.json to a block occurring prior to the deposit event's block.

By starting at a later block, the relayers will process all previous deposits and the events emitted as a result. Those whose nonces have not been executed will execute while those who did execute will reflect it in the ProposalStatus
