Liquidation Helper contract + necessary ABIs to perform liquidation
LiquidationHelper is not part of the protocol. Silo created this tool, mostly as an example.
Check deployments/ directory for deployed contract addresses.
You can find there also ABIs of the contracts including events definitions.
Necessary events can be found also in contracts/interfaces.
To perform liquidation, you have to have:
- borrower address,
- silo address
- and asset address.
Collect silo addresses by scanning for IRepository.NewSilo events.
Scan every block for IBaseSilo.Borrow events.
Note: watching one address is not enough, because we have many Silos.
With all above you will have all required data.
All users have to be constantly monitored and checked if they are solvent.
Use LiquidationHelper.checkSolvency to do that.
Watch for IBaseSilo.Repay events, then for that users, use LiquidationHelper.checkDebt to check,
if these users still have any debt left. If not, we can remove them from monitoring list.
They should jump back into a list when we detect them at IBaseSilo.Borrow.
Because of above, removing should be done before any other action.
Once we detect, that user is not solvent, we should immediately execute tx to liquidate him.
Use ISilo.flashLiquidate to do so.
You can also use LiquidationHelper.executeLiquidation to perform liquidation
or to see how this process looks in details.
NOTICE: most of the methods allows executing calls in batches.
We do not have any tests or calculations that will tell us what is the limit of input data.
