PLINC website will be kept up for one more year until end of 2022
After this time the only way of interacting with the contract is via the below OneClickDapps:
Amount returned upon exit can be calculated by dividing the exit pot amount (exitPot) by the total outstanding bonds (totalSupplyBonds) and multiplying this by your own bonds (bondsOutstanding)
Exit amount can be paid out via ExitPlincWithLoss write function
Take note that due to an accounting error on hub.plinc.io the exit pot is much bigger than what the contract actually contains so at some point exits cannot be paid out anymore. No workaround known.
