Liquid NFTs are NFT collections tokenized as fungible tokens (like BEP-20 tokens) enabling them to be instantly traded on decentralized exchanges such as ApeSwap, and making it possible to benefit from DeFi features such as yielding and staking.
LicoToken._writeCheckpoint(address,uint32,uint256,uint256) (contracts/LicoToken.sol#247-265) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (contracts/LicoToken.sol#257)
Don't use strict equality to determine if an account has enough Ether or tokens.

Contract ownership is semi-renounced (passed to a contract)
LicoToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (contracts/LicoToken.sol#113-154) uses timestamp for comparisons
Dangerous comparisons:
- require(bool,string)(block.timestamp <= expiry,delegateBySig: signature expired) (contracts/LicoToken.sol#152)
Avoid relying on block.timestamp.

LicoToken.getChainId() (contracts/LicoToken.sol#272-276) uses assembly
- INLINE ASM (contracts/LicoToken.sol#274)
Do not use evm assembly.
