Recovery mechanisms for incidents #3105

Open RafaelAPB opened 7 months ago

RafaelAPB commented 7 months ago

It is still not clear what a good incident response framework and interfaces should be for cross-chain applications. [Some info in our recent paper ](https://www.techrxiv.org/users/687326/articles/691934-sok-security-and-privacy-of-blockchain-interoperability(more). We expect the requirements of this issue to be clearer in the next months.

Requirements:

  1. Define processes that deal after a violation for the cross-chain model has been solved(and their different scenarios). Processes should include recovery mechanisms (such as revert transactions, update allow and deny lists, etc)
  2. Implement recovery mechanisms in the smart contract
  3. Implement recovery mechanisms in SATP core, namely the ability to send transactions to the bridge that trigger the recovery, and messages to counterparty gateways
  4. Expose endpoint in SATP that administers the recovery mechanisms (for example, manually contacting counterparty gateway)
  5. Update Prometheus metrics for incidents (time to resume normal operations, e.g., volume)

I will do this task.
