The Stack Hemi Builders Ship On

Quicknode is a leading Hemi RPC provider, serving mainnet and testnet over low-latency JSON-RPC from 17+ global regions with a 99.99% uptime SLA. You get private JSON-RPC and WSS endpoints, full archive data, the debug_* and OP-Node namespaces, and real-time Streams and Webhooks, on a platform that handles 500B+ requests a month across 80+ chains.

Hemi is a modular layer 2 built as a supernetwork of Bitcoin and Ethereum. Its hVM embeds a full Bitcoin node inside an EVM, so contracts can read Bitcoin state directly. It uses ETH for gas and settles security to Bitcoin. Mainnet runs on chain ID 43111.

Create a free Quicknode account, select Hemi, and a private RPC URL is generated instantly. You get full method coverage and rate limits that scale with your plan. No credit card is required for the free tier.

A Hemi node is a server that validates blocks and answers JSON-RPC requests for the Hemi network. Running your own means managing sync, storage, upgrades, and archive retention. With Quicknode you connect to a managed Hemi endpoint with HTTPS and WSS, full archive access, and a 99.99% uptime SLA, with no infrastructure to maintain.

Quicknode supports the full Hemi Ethereum JSON-RPC over HTTPS and WSS, including eth_call, eth_getLogs, eth_sendRawTransaction, und eth_subscribe, plus the debug_* namespace and the OP-Node API (optimism_syncStatus, optimism_outputAtBlock) for rollup sync status and output roots. Real-time Streams and Webhooks complete the data stack.

Yes. Quicknode runs full archive nodes for Hemi with no pruning, plus the Debug API for debug_traceTransaction und debug_traceBlockByNumber. You can query historical state and trace transactions for indexing, simulation, and analytics.

Yes. Hemi is EVM compatible. Deploy existing Solidity contracts with Hardhat, Foundry, or Remix without modification, and use ethers.js, web3.js, viem, and @quicknode/sdk against your Quicknode endpoint exactly as you would on Ethereum.

Quicknode serves Hemi mainnet (chain ID 43111) over HTTPS and WSS, with full archive data and real-time Streams and Webhooks. The Hemi Sepolia testnet (chain ID 743111) is also available.

Quicknode serves Hemi from 17+ global regions behind a 99.99% uptime SLA, with automatic failover and low-latency routing. The same infrastructure handles 500B+ requests a month across 80+ chains, so your Hemi apps stay responsive under load.

Quicknode offers a free tier for Hemi with no credit card required, so you can get a mainnet or testnet endpoint in seconds. Paid plans scale with request volume and add higher rate limits, and enterprise plans add dedicated infrastructure and a 99.99% uptime SLA.

Hemi mainnet uses chain ID 43111 and ETH as the native gas token. The Hemi Sepolia testnet uses chain ID 743111. To add mainnet to a wallet, use your Quicknode RPC URL, chain ID 43111, the currency symbol ETH, and the explorer at explorer.hemi.xyz.

Use Quicknode Streams for backfill and real-time blocks, logs, and traces delivered to your datastore, and Webhooks for push notifications on addresses and events. For in-app subscriptions, connect over WSS and use eth_subscribe.

Hemi is built for Bitcoin-aware DeFi: lending and staking against native BTC, tunnels between Bitcoin and Ethereum, and apps that need programmable access to Bitcoin state with EVM tooling.
