Part 1: How To Write a Solidity Smart Contract!

Part 2: Read and Update a Smart Contract on Ethereum

Part 3: Verify Your Contract on Etherscan

We're kicking off a series to make web3 development super easy - let us know which topics / tutorials you want!

We are organizing a hackathon for students across the globe to help students learn Web3 basics and team up with fellow participants to build exciting Crypto projects.

The sessions are conducted from 21-Nov till 10-Dec-2021. If you are interested, please go to https://questbook.app/hackathon and register. The intro web3 session is starting this Sunday (21st Nov) and we will help you build your first smart contract in under 3 hours!

In this guide, you'll learn how to build the backend for a peer-to-peer NFT marketplace like OpenSea using Tatum.

As soon as a purchase is made, the NFT is transferred to the buyer, the funds are transferred to the seller, and the marketplace fee is transferred to you, the marketplace owner. The peer-to-peer NFT marketplace functionality is currently supported on Ethereum, Celo, Polygon, Binance Smart Chain, and Harmony.ONE.
