  • Blockchain transactions decoding: making wallet activity understandable

    Lets look the events of Open Zeppelin’s ERC20 token contract:
  • I get an "ambiguous primary types or unused types" error when trying to mint an NFT requiring 2 signatures via EIP712
    3 projects | /r/solidity | 24 May 2023
    I modified my code to use EIP712 to require an authorized wallet to also sign in order for an NFT to be minted. I based this off of this: https://github.com/OpenZeppelin/openzeppelin-contracts/blob/7e814a3074baa921db584c180ff6e300cdec8735/contracts/token/ERC20/extensions/ERC20Permit.sol. This is an example of someone calling a smart contract containing this ERC20Permit.sol code https://github.com/Uniswap/v3-periphery/blob/main/test/shared/permit.ts. This particular ERC20Permit.sol code is designed to allow an account to approve ERC20 spend limits without spending gas fees but the same underlying mechanisms could be applied to my use case.

    v4.8.2 of OpenZeppelin contracts and contracts-upgradeable bug fix for ERC721Consecutive that could cause a balance overflow when _mintConsecutive was used for batches of size 1 breaking changes to ERC721: the internal function _beforeTokenTransfer will no longer update balances when batchSize is greater than 1

    In the next step of my journey, I went to Github to see what other people were building. I didn't fine much. My heros [OpenZeppelin](https://github.com/OpenZeppelin/openzeppelin-contracts/tree/master/contracts/interfaces) don't seem to have any examples in their repository. Github's search yielded no results. Some Google searches finally did land me on two repositories. One is [an implementation of ERC-5114](https://github.com/TeamSHARKZ/soulbound) - horray!. The other one one of those traditional [awesome lists](https://github.com/attestate/awesome-soulbound-tokens). Great resource and introduced me to a standard I previously missed, [ERC-4973](https://eips.ethereum.org/EIPS/eip-4973). Of course, having completely missed a token reinforced how easy it is to miss something obvious along the way and encourages me to reach out and ask the community for more information.

    Now create a folder named IERC20.sol inside your contracts folder and paste the following code into it. This is the ERC20 interface we will need to interact with the USDC contract. You can also find this code here
  • Generating Decentralized identifier using ERC725 and ERC735

    You're trying to import a markdown (text) file that describes the ERC721 spec, not an actual ERC721 compliant smart contract. I believe what you're trying to import is https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/token/ERC721/ERC721.sol
  • Question about implementing a UUPS proxy

    Look at TransparentUpgradeableProxy.sol, but the actual delegation happens in one of the contracts it inherits: Proxy.sol.

    Let's grab some examples from OpenZeppelin's TimelockController spec. In a Timelock, operations can have different states. We can write a rule that checks, for instance, that calling execute is the only way for moving an operation from ready to done state.
