Ref: A-16

  • Add automatic publisher funding: when a publisher's ETH balance drops below a configurable threshold, a dedicated funding account tops it up
  • Funding account is configured via the keystore's fundingAccount field and controlled by PUBLISHER_FUNDING_THRESHOLD / PUBLISHER_FUNDING_AMOUNT env vars

Instead of sending a transaction for each publisher. Can we instead send a call to aggregate3value on the Multicall3 contract.

We probably need to load the state and resume monitoring for the funder as well.

return lastUsedComparison;

void this.triggerFundingIfNeeded().catch(err => this.log.error('Error in funding check', { err }));

I think we should introduce async start() and stop() functions for this PublisherManager. Inside these functions we should call loadState and interrupt.

Then, within start we should create a RunningPromise which calls triggerFundingIfNeeded periodically.
