To build a one-stop, secure, most profitable, easy-to-use, flexible YaaS platform that is comprehensive to all blockchains for users in order to meet all their yield needs.
To enable other projects to improve the capital efficiency they produce through their incentive programs (such as liquidity mining, transaction mining, borrowing mining, etc.). This way, other projects can pay the minimum capital cost to obtain maximum liquidity and user attention.

UpToken._writeCheckpoint(address,uint32,uint256,uint256) (contracts/UpToken.sol#210-228) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (contracts/UpToken.sol#220)
Don't use strict equality to determine if an account has enough Ether or tokens.

Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

UpToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (contracts/UpToken.sol#81-122) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(now <= expiry,UP::delegateBySig: signature expired) (contracts/UpToken.sol#120)
Avoid relying on block.timestamp.
