JUT [Jumpn Unstake] Token

Unable to find manual contract audit (e.g. Certik, PeckShield, Solidity...)

GovernanceDAO._writeCheckpoint(address,uint32,uint256,uint256) (#1183-1201) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (#1193)
Don't use strict equality to determine if an account has enough Ether or tokens.

Contract locking ether found:
Contract JUT (#1312-1330) has payable functions:
- AccessControl.constructor() (#942-945)
- AccessControl.fallback() (#1029)
- AccessControl.receive() (#1030)
But does not have a function to withdraw the ether
Remove the payable attribute or add a withdraw function.
