  • Contract example with best practices?

  • Understanding NFT + ERC721 works
    1 project | | 16 Jan 2022
    I'm trying to better understand how their devs set up their smart contract. I've already pulled a simple preset from OpenZeppelin, But i'm trying to figure out like... is that it? Create a website that you can connect your wallet to, then mint to this, which is a live deployed version of this on the Eth blockchain and that's it? What about all the people who have minted? Do we need to keep track of them? If you wanted to provide payouts to the holders of the NFT, would that have to be structured in the same smart contract?
  • Looking for great DAO examples in Solidity

    Are you already familiar with OpenZeppelin? Their contracts are battle-tested and industry standard; not sure if they offer exactly what you need out of the box, but it’s possible to extend their code.
  • [UniswapV2] UniswapV2ERC20.sol
    1 project | | 5 Jan 2022
    This is quite similar to OpenZepplin’s ERC20.sol, but with some unique features.
  • How is safemath's "mul" preventing overflow?
    1 project | | 5 Jan 2022
    function mul(uint256 a, uint256 b) internal pure returns (uint256) { // Gas optimization: this is cheaper than requiring 'a' not being zero, but the // benefit is lost if 'b' is also tested. // See: if (a == 0) { return 0; } uint256 c = a * b; require(c / a == b, 'SafeMath: multiplication overflow'); return c; }
