How you build an ERC20 airdrop - Allowlist with merkle tree

Video Description

In this video, learn how to build a claimable ERC-20 airdrop. This means that a user can claim their tokens and pay for their own gas to claim the tokens. In this tutorial we will build a merkle tree generator to create a merkle tree root for you contract. We will deploy an ERC-20 and an airdrop contract and build a web3 application to claim tokens. **Mumbai testnet support has been officially deprecated. Transition to the Amoy testnet for improved scalability and reduced gas fees.** GitHub repo: https://github.com/thirdweb-example/claimable-erc20-youtube Guide: https://blog.thirdweb.com/create-an-nft-mint-farcaster-frame/ ERC-20 Token contract: https://thirdweb.com/thirdweb.eth/TokenERC20 ERC-20 Airdrop contract: https://thirdweb.com/thirdweb.eth/AirdropERC20Claimable thirdweb Engine Docs: https://portal.thirdweb.com/engine/getting-started How to setup local thirdweb Engine: https://youtu.be/HfZ6uVqC9JY thirdweb API: https://thirdweb.com/dashboard/settings Creating an API: https://youtu.be/G3bvXfE-OMg thirdweb Docs: https://portal.thirdweb.com/ Join our Community of over 30,000 Web3 builders: https://discord.gg/thirdweb thirdweb Official Site: https://thirdweb.com/dashboard thirdweb Twitter: https://twitter.com/thirdweb Timestamps: 00:00 Demo of claimable ERC-20 airdrop 02:40 What is a merkle tree and why use it for an allowlist 04:22 Overview of how to create a claimable ERC-20 airdrop 05:50 Create a new thirdweb project 07:55 Build a merkle tree generator 12:10 Deploy ERC-20 and ERC-20 airdrop contracts 19:45 Build a claimable ERC-20 airdrop app 28:15 Create a function to generate a merkle proof for the connected wallet 32:48 Conclusion
