My playground project to learn Rust and blockchain development

Learning Rust and Blockchain development on Ethereum using lessons from:

• Ethereum Blockchain Developer
  • The Blockchain Messenger
  • Smart Money - Deposit and Withdrawals
  • Shared Wallet
• Solidity by Example
  • Voting

stack: Rust, Actix, Ethers-rs, Solidity, Foundry, Tailwind (DaisyUI), Tera, HTMX

Set-up

• install Foundry, Solidity (solc), Tailwind and Direnv

make prepare-env

• optionally install web3 CLI to interract with the Anvil testnet (cast also works)

make install-web3cli

• start the Anvil local testnet

make start-testnet

• see the accounts and private keys on the start-up output and update PRIVATE_KEY AND ACCOUNT in the .envrc file and update the env vars with direnv allow

Interact with the testnet

Use the Makefile targets to interract with the Smart Contracts.

• deploy contract from a lab (e.g. Lab1)

make lab1-deploy

• export the returned contract address to the CONTRACT_ADDRESS_THEBLOCKCHAINMESSENGER env var, or do the two steps in a single step:

export CONTRACT_ADDRESS_THEBLOCKCHAINMESSENGER=$(make lab1-deploy)

• get the transaction details

make get-tx TX_HASH=0x5a6f304960784db9bee2df3de0c8e91b4afdfda748fa3fb80527baa786e53fab

• call contract method

make lab1-updateTheMessage MSG="Hello World!"

• get the last contract data or at a given block

make lab1-get-data
make lab1-get-data-at-block BLOCK_NR=1

• get the account balance

make get-balance

Run the app

You can use already deployed Smart Contracts by setting the contract addresses in the .envrc file and enabling them with direnv allow.

• start the app

make run

• open the page on localhost:8080

• open Lab1 (The Blockchain Messenger), wait until the contract gets deployed (in case you didn't set the contract address in .envrc) and submit a new transaction
