RGBEP20.addLiquidity(uint256,uint256) (contracts/libs/RGBEP20.sol#743-756) sends eth to arbitrary user
Dangerous calls:
- pancakeRouter.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (contracts/libs/RGBEP20.sol#748-755)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

Combination 1: Reentrancy vulnerabilities + Functions that send Ether to arbitraty destination. Usual for scams. May be justified by some complex mechanics (e.g. rebase, reflections). DYOR & manual audit are advised.

Unable to verify that contract auditor is trusted: Certik, Quantstamp, Hacken, Solidity, Paladinsec, Openzeppelin, Verichains

ZaifToken._writeCheckpoint(address,uint32,uint256,uint256) (contracts/ZaifToken.sol#219-237) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (contracts/ZaifToken.sol#229)
Don't use strict equality to determine if an account has enough Ether or tokens.
