What is Unichain?

Unichain is an Ethereum Layer 2 network built on the Superchain (an Optimism-led network of OP Stack chains that share security, standards, and tooling). It’s an EVM-compatible rollup designed for fast, low-cost transactions and seamless Ethereum interoperability, intended to be a faster and cheaper L2 and a home of DeFi and liquidity across chains. It supports standard Ethereum JSON-RPC methods along with OP-Node–specific endpoints for rollup state and synchronization.

Interacting With Unichain APIs

Unichain exposes Ethereum-compatible JSON-RPC and rollup-specific methods that allow developers to interact with the network programmatically. You can query blocks and transactions, deploy and interact with smart contracts, and access rollup status and configuration.

You can connect by running your own node or by using a hosted provider such as QuickNode, which offers reliable, low-latency access without the need to manage infrastructure.

Make Unichain API Calls

The quickest way to start building on Unichain is to create a QuickNode endpoint and send your first request. QuickNode provides managed Unichain endpoints, offering:

High reliability — globally distributed infrastructure designed to minimize downtime
Enhanced performance — optimized latency and request handling for production-grade apps
