Hemi RPC
Hemi Overview
Hemi is a modular Layer-2 protocol that integrates Bitcoin and Ethereum as unified components of a supernetwork. Rather than treating these blockchains as isolated ecosystems, Hemi embeds Bitcoin awareness directly into an Ethereum Virtual Machine, enabling developers to build applications that leverage both blockchains simultaneously. The platform uses Proof-of-Proof consensus to anchor transactions to Bitcoin's security model while maintaining Ethereum's execution layer familiarity.
Hemi provides two core technical components: the Hemi Virtual Machine (hVM) combines a full Bitcoin node within an EVM environment, and the Hemi Bitcoin Kit (hBK) grants smart contracts granular access to Bitcoin state. This architecture enables Bitcoin DeFi applications previously impractical through standard EVM implementations. As a fully EVM-compatible platform, Hemi allows developers to use standard Ethereum tooling like Hardhat, Foundry, and Web3 libraries while accessing cross-chain functionality through its Tunnels feature for trustless asset transfers.
Interacting with Hemi's APIs
Hemi supports standard Ethereum JSON-RPC methods along with Debug APIs and OP-Node JSON-RPC API extensions, enabling developers to use Ethereum's native tools without modification. The platform maintains full compatibility with Solidity and existing Ethereum development workflows.
The Quicknode Hemi documentation is continuously evolving as the network undergoes upgrades and changes, so we highly recommend cross-referencing with the official Hemi documentation for the latest updates and features.
Make Hemi API Calls
The quickest way to start building on Hemi is to create a Quicknode endpoint and send your first JSON-RPC request.
Quicknode provides managed Hemi endpoints, giving you immediate access to Hemi Testnet and Mainnet without the overhead of running infrastructure. These endpoints offer:
- High reliability – globally distributed infrastructure designed to minimize downtime
- Enhanced performance – optimized latency and request handling for production-grade apps
- Integrated ecosystem – additional functionality through specialized APIs (add-ons) on the Quicknode Marketplace and products like Streams
Visit the QuickStart page to create your endpoint and send your first request.
