Record `FaultRecord` events from all PDP-based service contracts

[silent-cipher]

Currently, we only record fault records from SimplePDPServiceContract deployed at

• mainnet - 0x805370387fA5Bd8053FD8f7B2da4055B9a4f8019
• calibration - 0x6170dE2b09b404776197485F3dc6c968Ef948505

However, other service contracts using PDPVerifier may also emit FaultRecord events with the standard event signature:

event FaultRecord(indexed uint256, uint256, uint256);

Proposal:

We should extend the subgraph to support capturing FaultRecord events from any PDP-based service contract that emits this standard event. This can be achieved by:

• Defining a data source template for PDP service contracts.
• Dynamically instantiating these templates in the handler for the proofSetCreated event (or any relevant trigger).

This approach allows the subgraph to dynamically follow all new service contracts and record their fault events without requiring static entries in the manifest.

can i work on this @silent-cipher ?

Hey @DarkLord017 thanks for your interest!
I’m no longer maintaining this project. You can check with the current maintainers to see if they’re open to contributions on this issue.

event FaultRecord(indexed uint256, uint256, uint256);

The FaultRecord event is not found in the PDPVerifier.sol file.

[silent-cipher]

You're right the FaultRecord event isn't in PDPVerifier.sol itself.
What I meant in the issue description is that this event can be emitted by service contracts that use the PDPVerifier (for example, the Warm Storage Service). The idea was to make the PDPService contracts dynamic data sources in the subgraph so it can capture FaultRecord events from any pdp-based service, instead of being limited to a single one.

@ZenGround0 @juliangruber can i pick up the issue
