Learn more about Core

What is Core?

Core is an EVM chain that merges Bitcoin’s security via delegated BTC hash with proof-of-stake to secure smart contracts and DeFi.

How to get Core RPC endpoint?

Sign up for a free Chainstack account and open your project dashboard. In the dashboard, choose Add node, select Core, and provision either a dedicated node or an elastic cluster. After the node syncs, open Access & credentials and grab the RPC URL for immediate integration.

How to run a Core node?

A Core Global Node from Chainstack merges BTC security and EVM convenience instantly. Upgrade to a Dedicated Node for validator staking or cross-chain swaps. Self-hosting forces you to link BTC hash delegations, manage PoS keys, and patch snap sync.

What is Core RPC API?

Core Chain blends Bitcoin hashpower with EVM JSON-RPC; core_getBTCRelay returns proof-of-work checkpoints. eth_call works normally, while withdrawals monitor relay status. Gas estimates factor in both PoS and BTC security fees.

How much does it cost to run a Core RPC?

A Core node plus BTC relay hovers around US $140-240 / month, driven by dual-chain storage. Validator staking adds further complexity. An RPC provider such as Chainstack is the economical pick.

Is Core RPC free?

Core Chain publishes free endpoints, yet BTC relay spikes disrupt uptime. Chainstack’s free 3 million-request tier solves that stability issue.

How to setup a Core RPC?

Copy the Core Chain endpoint from Chainstack. Add it to MetaMask (Custom) or change your backend provider to route through Chainstack.

Notes for Core API

When communicating with a Core node, the client implements a JSON-RPC specification compatible with Ethereum. The recommended libraries are ethers.js for JavaScript or web3.py for Python.

EVM-compatible L1 using Satoshi Plus consensus — a hybrid PoW + DPoS mechanism that leverages Bitcoin miner hash power for security.

You can also access Core directly through the Chainstack MCP server — query live on-chain data, deploy nodes, request testnet funds from the faucet, and search Chainstack docs from Claude, Cursor, Windsurf, ChatGPT, Codex, Pi, Gemini, or any MCP-compatible or SKILL-compatible AI agent.
