Hello. As the title says, Working on a project where I need to split all the letters in a string into separate strings in an array. I have imported this library that does something similar, but It wants a character to split by ( for example "-" or " "). I've been thinking about this for a long time but I can't for the life of me figure out how to fix this. Anyone here have any tips or knowledge how I can achieve this? Also if its possible to do in one function instead of 2 as I have been trying with now that would be super nice. So all in all, I want one function that makes the user write a string, that will be divided into an array of strings for each letter of the input. Thanks in advance.

I found a helpful library that seems to do the trick (I've kind of incorporated below). I'm coming from Python so have been thinking about this in a pythonic way -- My logic (still early in thinking about this) goes something like this:

// SPDX-License-Identifier: GPL-3.0 pragma solidity ^0.8.20; import "https://github.com/OpenZeppelin/openzeppelin-contracts/blob/v5.0.0/contracts/token/ERC20/ERC20.sol"; interface Sfs {     function register(address _recipient) external returns (uint256 tokenId); } contract ModeToken is ERC20 {     address feeReceiver = msg.sender;     constructor() ERC20("ModeTokenSFSTest", "SFST2") { //Example amount to mint our ERC20         _mint(msg.sender, 1000 10 * 18);   // This is the SFS contract address on testnet Sfs sfsContract = Sfs(0xBBd707815a7F7eb6897C7686274AFabd7B579Ff6); //Registers this contract and assigns the NFT //to the deployer of this contract sfsContract.register(msg.sender);     } }

Lets look the events of Open Zeppelin’s ERC20 token contract:

ERC-777 is difficult to implement properly, due to its susceptibility to different forms of attack(opens in a new tab). It is recommended to use ERC-20 instead. This page remains as a historical archive.
