Tevm Getting Started

This repo demonstrates the Tevm Getting Started Guide. Every step of the guide is it's own commit.

Features demonstrated

• Creating an in-memory EVM with createMemoryClient
• Making requests to the in-memory EVM with viem actions such as memoryClient.getBlockNumber and memoryClient.getTransactionReceipt
• Querying account information with memoryClient.tevmGetAccount
• Modifying account information with memoryClient.tevmSetAccount
• Using the accounts prefunded with 1000 eth
• Executing the EVM and creating a transaction with memoryClient.tevmCall
• Mining a new block with memoryClient.tevmMine
• Deploying a contract with memoryClient.tevmDeploy
• Calling a contract with meoryClient.tevmContract
• Reducing boilerplate of contract calls in Tevm and Viem with Tevm Contracts
• Importing contracts into tests and running them as scripts
• Running JavaScript in solidity scripts

There are also commits showing the boilerplate needed to run Tevm in the browser and set up the automatic solidity contract imports.

Main files

• src/main.ts demonstrates the most basic tevm features such as modifying accounts deploying and calling contracts and using the viem api.
• src/counter.spec.ts demonstrates more advanced tevm features such as solidity scripting and running javascript in solidity.

Stack blitz

This repo is available as a stackblitz here. You will have to enable the local version of typescript after starting the stakblitz. More information is in a comment at the top of src/main.ts.
