Tevm Overview

Tevm is a lightweight EVM that runs in the browser for local testing and debugging.

Quick Start

import { createMemoryClient } from 'tevm'

const client = createMemoryClient()

// Execute a contract call
const result = await client.tevmCall({
  to: contractAddress,
  data: '0x...'
})

Key Capabilities

• In-memory EVM - No external node required
• Fork mode - Fork from mainnet/testnet
• EVM tracing - Step-by-step execution debugging
• Account impersonation - Act as any address
• Time manipulation - Control block timestamps

Skills

• Setup: tevm-setup - Client initialization
• Actions: tevm-actions - Core API (call, mine, etc.)
• Account Management: tevm-account-management - State manipulation
• Events: tevm-events - EVM execution tracing
• Contract Deployment: tevm-contract-deployment - Deploy with ethers
• Debugging: tevm-debugging - Gas profiling, tracing

Use Cases

1. Frontend testing - Test contract interactions without mainnet
2. Contract debugging - Trace execution at opcode level
3. Fork testing - Fork mainnet state locally
4. CI/CD - Fast test execution
