HADO (HDO) is a decentralized utility token developed for the HADONFT marketplace launched on Binance Smart Chain (BSC). HADO stands for Help Art Deliver Opportunity. Not only does HADO offer an open low-fee NFT marketplace, but we will reach out and help artists with special needs and differing abilities to instruct and encourage them to monetize their talents on HADO.
HADO offers unique promotional opportunities for artists by providing qualified artists with a professionally written biography and article to help them promote awareness and increase sales. These articles will be available on the “hado NFT news & review” tab and artists can direct their followers to the content to gain additional traction.
All artists that mint on HADONFT indirectly help us support and promote artists with special needs.
HADO.swapAndLiquify(uint256) (#2130-2165) sends eth to arbitrary user
Dangerous calls:
- marketingWallet.transfer(marketingAmount) (#2155)
HADO.addLiquidity(uint256,uint256) (#2195-2207) sends eth to arbitrary user
Dangerous calls:
- uniswapV2Router.addLiquidityETH{value: ethAmount}(address(this),tokenAmount,0,0,owner(),block.timestamp) (#2198-2205)
Ensure that an arbitrary user cannot withdraw unauthorized funds.

HADODividendTracker.getAccount(address) (#1574-1617) uses timestamp for comparisons
Dangerous comparisons:

Dangerous comparisons:
- lastClaimTime > block.timestamp (#1639)
