The 1st Web3 Casino with Play to Earn and Stake to Earn
Launched on the 18th of March 2022 by a team around the world including Europe, Asia, and Africa, LuckyChip is a Prediction GameFi with Bet Mining and Bank Farming Features. The Game consists of a lot of amazing features which include: Play to Earn, Stake to Earn, Refer to Earn, Bet Mining, and Bank Farming.
What Makes LuckyChip (LC) Unique?
Using ChainLink VRF V2 Blockchain technology allows for faster (usually instant) prize distributions as well as complete tracking and documentation, regardless of the magnitude of the win. Furthermore, the blockchain confirms both the players and their tickets, lowering the risk of data loss, destruction, or tampering. This system also guarantees that the entire procedure is transparent and random.

LCToken._writeCheckpoint(address,uint32,uint256,uint256) (contracts/token/LCToken.sol#564-582) uses a dangerous strict equality:
- nCheckpoints > 0 && checkpoints[delegatee][nCheckpoints - 1].fromBlock == blockNumber (contracts/token/LCToken.sol#574)
Don't use strict equality to determine if an account has enough Ether or tokens.

LCToken.delegateBySig(address,uint256,uint256,uint8,bytes32,bytes32) (contracts/token/LCToken.sol#430-471) uses timestamp for comparisons
