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

@windingtree/sdk-contracts-manager

This package is a core component of the Winding Tree SDK. It provides an interface to interact with smart contracts, allowing developers to execute various operations including transactions and contract function calls.

The ProtocolContracts class exposed by this package contains methods to interact with smart contracts for entities such as offers and deals. These methods support functionalities like creating, fetching, and cancelling deals, registering entities, and handling various deal statuses (checking-in, checking-out, rejecting, claiming, and refunding).

Installation

pnpm i @windingtree/sdk-contracts-manager

Key Concepts

  • PublicClient and WalletClient are used for blockchain interactions. A PublicClient is used for reading blockchain state and data, while a WalletClient is used for writing transactions to the blockchain.
  • The _sendHelper method is a private utility used to send transactions to the blockchain network.
  • The TxCallback is a type definition for a callback function that will be called with the transaction hash when a transaction is sent.
  • The methods in the ProtocolContracts class follow a pattern where they accept the parameters necessary for the specific blockchain operation, an optional WalletClient to specify the signer of the transaction, and an optional TxCallback that will be called with the transaction hash.

Usage

import { createPublicClient, createWalletClient, http } from 'viem';
import { polygonZkEvmTestnet } from 'viem/chains';
import { ProtocolContracts } from '@windingtree/sdk-contracts-manager';

// Instantiate with options
const protocolContracts = new ProtocolContracts({
  contracts: {
    /* contracts configuration */
  },
  publicClient: createPublicClient({
    chain: polygonZkEvmTestnet,
    transport: http(),
  }),
  walletClient: createWalletClient({
    chain: polygonZkEvmTestnet,
    transport: http(),
    account: node.signer.address,
  }),
});

// Use methods to interact with the blockchain
protocolContracts.createDeal(/* parameters */);
protocolContracts.getDeal(/* parameters */);
// and other methods...
