N00b21337How to get Uniswap V3 liquidity pool address for whitelisting?
Similar to what we did for Uniswap V2 on how to find address of smart contract pool that will be generated we can do the same for V3 https://mirror.xyz/n00b21337.eth/0QkNt3NnLnnUSy4jFmWnaeRr_38Z3wlYKKf1O6URG3c Depending on what chain we are at, you can find all the addresses of Factories here https://github.com/Uniswap/sdk-core/blob/5365ae4cd021ab53b94b0879ec6ceb6ad3ebdce9/src/addresses.ts#L135 Aim for the v3CoreFactoryAddress values.**So there are a few methods to do that, one could be to us...
N00b21337Example of implementation of EIP 4906 metadata updates
EIP 4096 has an interesting method of updating your metadata with events, more details here. https://eips.ethereum.org/EIPS/eip-4906 So lets see how to implement it with an example. First you need to create a file with interface that has this code in itpragma solidity ^0.8.0; import "@openzeppelin/contracts/utils/introspection/IERC165.sol"; /// @title EIP-721 Metadata Update Extension interface IERC4906 is IERC165 { /// @dev This event emits when the metadata of a token is changed. /// Third-...
N00b21337Transaction Bytecode vs Deployed Bytecode, differences and how to read them
Main difference between deployed bytecode or runtime bytecode and bytecode that is shown in deployed transaction is that later has initial code in it and its bigger in size. So what is initial(init) code?A smart contract's constructor is a one-time function not stored on the blockchain but present in the initial code. When creating a contract, users can also send native currency. It's vital to ensure the contract can accept this currency at deployment. If it can't, the creation...

When I want to rewrite requires to custom errors in bigger blocks of solidity code I solve it with chatGPT. I use prompt below to make the solution work out of the box and just c/p code.
Rewrite this code in a way that reverts are transformed to custom solidity errors use this pattern of replacement require(success, "Transfer failed");
replace with error TransferFailed(); //Transfer failed if(!success){ revert TransferFailed();}
Group all error definition at the beginning of the code, use string from replace text as comment.
