GUN is an ecosystem of tools that let you build community run and encrypted applications - like an Open Source Firebase or a Decentralized Dropbox.

The Internet Archive and 100s of other apps run GUN in-production. GUN was also part of Twitter's bluesky initiative!

• Multiplayer by default with realtime p2p state synchronization!
• Graph data lets you use key/value, tables, documents, videos, & more!
• Local-first, offline, and decentralized with end-to-end encryption.

Decentralized alternatives to Zoom, Reddit, Instagram, Slack, YouTube, Stripe, Wikipedia, Facebook Horizon and more have already pushed terabytes of daily P2P traffic on GUN. We are a friendly community creating a free fun future for freedom:

Quickstart

GUN is super easy to get started with:

• Try the interactive tutorial in the browser (5min ~ average developer).
• Or npm install gun and run the examples with cd node_modules/gun && npm start (…

web3-ui

In Development - Refactoring in Progress 🏗️

A library of UI components specifically crafted for web3 use cases.

Package name	Current version
(Deprecated) @web3-ui/core
@web3-ui/components
(Deprecated) @web3-ui/hooks

Quick start

Note: This is for the current public release. This library is being refactored and instructions will change.

1. Install the package

$ yarn add @web3-ui/core ethers

2. Setup the Provider

import { Provider, NETWORKS } from '@web3-ui/core';

function MyApp({ Component, pageProps }) {
  return (
    <Provider network={NETWORKS.mainnet}>
      <Component {...pageProps} />
    </Provider>
  );
}

3. Use the components and hooks

import { ConnectWallet, useWallet } from '@web3-ui/core';
function Home() {
  const { connection } = useWallet();

  return (
    <div>
      <ConnectWallet />
      <div>{connection.ens || connection

MetaMask

MetaMask is a mobile wallet that provides easy access to websites that use the Ethereum blockchain.

For up to the minute news, follow our Twitter or Medium pages.

To learn how to develop MetaMask-compatible applications, visit our Developer Docs.

MetaMask Mobile

Environment Setup

The code is built using React-Native and running code locally requires a Mac or Linux OS.

• Install sentry-cli tools: brew install getsentry/tools/sentry-cli

• Install Node.js version 16

  • If you are using nvm (recommended) running nvm use will automatically choose the right node version for you.

• Install Yarn v1

• Install the shared React Native dependencies (React Native CLI, not Expo CLI)

• Install cocoapods by running:

sudo gem install cocoapods -v 1.12.1

Device Environment Setup

Android

• Install Java. To check if Java is already installed, run:

  java -version

• Install the Android SDK, via Android Studio

A decentralized cryptological network offering accessible, intuitive, and extensible runtimes and interfaces for secrets management and dynamic access control.

The NuCypher network provides accessible, intuitive, and extensible runtimes and interfaces for secrets management and dynamic access control.

• Accessible - The network is permissionless and censorship-resistant There are no gate-keepers and anyone can use it.
• Intuitive - The network leverages the classic cryptological narrative of Alice and Bob (with additional characters where appropriate). This character-based narrative permeates the code-base and helps developers write safe, misuse-resistant code.
• Extensible - The network currently supports proxy re-encryption but can be extended to provide support for other cryptographic primitives.

Access permissions are baked into the underlying encryption and access can only be explicitly granted by the data owner via sharing policies Consequently, the data owner has ultimate control over access to their data At no point is the data decrypted nor can the underlying private…

nft api

NFT API that returns resolved metadata and has all information about all NFT collections, users, transactions. Cross-Chain NFT API.

NFT API is a central part of any NFT dapp. Whether you build an NFT game, wallet, marketplace, analytics site, dashboard or something else based on NFTs you need to have a reliable NFT API that can help you get things such as:

1. NFT Metadata
2. NFT Ownership data
3. NFT Transfer data
4. NFT Prices

See full table of contents.

If these features are required in your dapp - keep reading!

Chains supported

The NFT API supports the following chains:

1. Ethereum (ETH)
2. Binance Smart Chain (BSC)
3. Polygon (MATIC)
4. Avalanche (AVAX)
5. Fantom (FTM)
6. CRONOS (CRO)
7. Solana (SOL)
8. Testnets are fully supported.

This API is widely used in the web3 industry and is powering many prominent web3 projects.

Matic SDK

This repository contains the maticjs client library. maticjs makes it easy for developers, who may not be deeply familiar with smart contract development, to interact with the various components of Matic Network.

This library will help developers to move assets from Ethereum chain to Matic chain, and withdraw from Matic to Ethereum using fraud proofs.

👋🏼 What is learn-web3-dapp?

We made this decentralized application (dApp) to help developers learn about Web 3 protocols.

It's a Next.js app that uses React, TypeScript and various smart contract languages (mostly Solidity and Rust).

We will guide you through using the various blockchain JavaScript SDKs to interact with their networks. Each protocol is slightly different, but we have attempted to standardize the workflow so that you can quickly get up to speed on networks like Solana, NEAR, Polygon and more!

• ✅ Solana

• ✅ Polygon

• ✅ Avalanche

• ✅ NEAR

• ✅ Tezos

• ✅ Secret

• ✅ Polkadot

• ✅ Celo

• ✅ The Graph

• ✅ The Graph for NEAR

• ✅ Pyth

• 🔜 Ceramic

• 🔜 Arweave

• 🔜 Chainlink
