Description

Goes Up Higher Reborn (GUHR) represents the rebirth of GUH. GUHR is a first of its kind elastic autonomous community token with renounced ownership. GUHR is both contractually guaranteed to increase in price until it far exceeds Bitcoin’s price (based on the BTC/BNB pair). To achieve this goal, GUHR dynamically adjust its supply to achieve an increasing price peg, which begins at $0.001 and increases 5% every 4 hours for 360 epochs, at which point it will peg to Bitcoin’s current market price + 1% every 4 hours.

GUHR.addLiquidity(uint256,uint256) (#982-996) sends eth to arbitrary user

GUHR.burnAutoLP() (#1110-1116) ignores return value by uniswapV2Pair.transfer(owner(),balance) (#1115)
Use SafeERC20, or ensure that the transfer/transferFrom return value is checked.

Ownable._lockTime (#306) is never initialized. It is used in:
- Ownable.getUnlockTime() (#357-359)
- Ownable.unlock() (#370-375)
Initialize all the variables. If a variable is meant to be initialized to zero, explicitly set it to zero to improve code readability.
