Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

Readme

@xessential/react

@xessential/react offers React-specific context and hooks for integrating 0xEssential dApp tooling.

Our hooks are modeled after wagmi making it easy for developers to add features like MultiChain Connections, Gasless Transactions, NFT Global Entry and Account Delegation. These features can be mixed and matched, depending on developer needs and user preferences.

The goal is to provide users a simple and safe experience without sacrificing decentralization. The tools are built on open-source standards for simple adoption and no vendor lock-in.

Installation

The package is available via NPM:

  yarn add @xessential/react

useDelegatedAccount

useDelegatedAccount is a replacement for useAccount that uses DelegateCash as an account delegation source. This helps users stay safe in a hot wallet with user context from their vault.

If a DelegateCash user is connected to a hot wallet in your dapp, you should still use their vault wallet address for things like ENS name and avatar, NFT holdings and token balances. Users can browse web3 safely with a hot wallet holding minimal assets while still reading the chain as if they were connected to their vault.

This hook does not affect how other wagmi hooks like useContractWrite behave. The signer for those hooks will always be the current connected address. Any transactions you submit depending on account delegation must perform an onchain check.

Usage

import { useDelegatedAccount } from '@xessential/react'
import { useEnsName } from 'wagmi'

function App() {
  const {
    address, // `vaultAddress` || `signerAddress`
    isConnecting,
    isDisconnected,
    signerAddress,
    isDelegated,
    vaultAddresses,
    setVaultAddress,
  } = useDelegatedAccount();

  const {
    data: ensName,
    isError,
    isLoading,
  } = useEnsName({
    address, 
  });

  if (isConnecting) return <div>Connecting…</div>;
  if (isDisconnected) return <div>Disconnected</div>;
  return (
    <div>
      <p>Connected Address: {signerAddress}</p>
      {ensName && <p>Primary Ens: {ensName}</p>}
      {isDelegated && (
        <>
          <p>
            Vault Address: {address}
            {/* or `vaultAddress` */}
          </p>
          <p>Available Vault Addresses:</p>
          {vaultAddresses?.map((vault) => (
            <button key={vault} onClick={() => setVaultAddress(vault)}>
              {vault}
            </button>
          ))}
        </>
      )}
    </div>
  );
}

Return Value

{
   /* 
    The primary address for _user context_. If the user is connected to a delegated wallet, this returns vaultAddress
  */
  address?: `0x${string}`;

  /** Gas token balance for connected address */
  connectedBalance?: FetchBalanceResult;

  /** Array of addresses to which the connected address has delegated authority */
  delegatedAddresses: `0x${string}`[];

  /** Convenience function for the connected address having 0 balance */
  isBurner: boolean;

  /** Boolean for whether connected address is delegate of a vaultAddress */
  isDelegated: boolean;

  /** Connected address used for transaction signing.  */
  signerAddress?: `0x${string}`;

  /** Connected address used for transaction signing.  */
  setVaultAddress: (address: `0x${string}`) => void;

  /*
    Current selected vault address. If connected address is delegate of > 1 vaults, 
    a best guess default is selected. See `setVaultAddress`.
  */
  vaultAddress?: `0x${string}`;

  /** Array of addresses that have delegated to connected address */
  vaultAddresses?: `0x${string}`[];
