Connect to Celo through geo-balanced infrastructure that scales with request volume and routes traffic for reliable access across regions, in Full and Archive modes.
Run Celo workloads on isolated infrastructure with single-tenant resources, debug and trace APIs, and greater control over node configuration.
Build with managed Celo Mainnet RPC endpoints (chain ID 42220). Get standard Ethereum JSON-RPC over HTTPS and WSS — eth_*, net_*, web3_* — in Full and Archive modes.
SOC 2 Type II and ISO 27001 certified.
Celo runs on the OP Stack as an Ethereum L2, so the Ethereum tools you already use work against your Chainstack node.
Use standard Ethereum JSON-RPC with ethers.js, web3.py, Hardhat, Foundry, and MetaMask. Chainstack runs Celo on op-reth with op-node.
Read recent state at 1 RU, or reach historical state in Archive mode, where methods such as eth_call and eth_getBalance on blocks 127 or more behind the tip cost 2 RU.
Subscribe to new heads and logs over WSS with eth_subscribe, and use eth_getLogs and filters for event pipelines.
Debug and trace APIs are available on Global Nodes from a paid plan, and on every Dedicated Node, for tracing and indexer workloads.
Copy your endpoint from Access and credentials in the console, then run any of these.

Celo is an Ethereum L2 built on the OP Stack and exposes standard Ethereum JSON-RPC: eth_*, net_*, and web3_*, including eth_subscribe over WSS. Chainstack runs Celo on op-reth with op-node. Mainnet chain ID is 42220. admin_* is not served. Debug and trace APIs are available on paid plans (Global Node or Dedicated Node) and cost 2 RU on Global Nodes. Recommended libraries are ethers.js for JavaScript and web3.py for Python. Full requests cost 1 RU, and EVM state methods such as eth_call and eth_getBalance on blocks 127 or more behind the tip are archive-depth and cost 2 RU.
You can also access Celo through the Chainstack MCP server — query onchain data, deploy nodes, and search Chainstack docs from Claude, Cursor, Windsurf, ChatGPT, Codex, Pi, Gemini, or any MCP-compatible or SKILL-compatible AI agent.
