SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Viem integration enables developers to connect and interact with EVM blockchains directly from TypeScript/JavaScript apps, simplifying data access and write operations.

Core Features & Use Cases

  • Read on-chain data (balances, contract state, logs) using viem public and wallet clients.
  • Write transactions and interact with contracts (send, write, simulate) across multiple networks.
  • Rapid onboarding with clear transports, chains, and common patterns for education-research and production apps.

Quick Start

Install Viem integration in your project and begin using the provided examples to create public and wallet clients, then perform read, write, and contract operations against EVM networks.

FAQPage Schema
How do I read on-chain data from EVM blockchains using TypeScript?

You read on-chain EVM data in TypeScript by configuring a Viem PublicClient with a specific chain and transport. This setup enables your JavaScript application to fetch balances, contract state, and event logs directly from the blockchain.

What is the best way to send transactions across multiple EVM networks in JavaScript?

Sending transactions across multiple EVM networks in JavaScript is done by configuring a Viem WalletClient with appropriate chain definitions and transports. This approach handles write operations, transaction simulation, and contract interactions across different networks.

Can I use Viem for contract interactions in both Node.js and frontend applications?

Yes, you can use Viem for contract interactions in both Node.js and frontend applications. It provides the necessary client configurations and transport setups to execute read and write workflows seamlessly across these distinct JavaScript environments.

How do I set up transports and chain definitions for EVM data access?

You set up EVM data access by defining chain specifications and initializing transport layers when creating your Viem PublicClient and WalletClient. This configuration establishes the network connection required to execute read and write contract operations.

Does Viem integration support transaction simulation before sending writes to an EVM network?

Yes, Viem integration supports transaction simulation before sending writes to an EVM network. Developers can simulate contract interactions and write transactions to verify expected outcomes prior to executing them across multiple blockchain networks.
