Connect to Celo Mainnet and Celo Sepolia Testnet through geo-balanced infrastructure that scales with request volume and routes traffic for reliable access across regions. Mainnet runs 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 RPC endpoints on Mainnet (chain ID 42220) and the Celo Sepolia Testnet (chain ID 11142220). Get standard Ethereum JSON-RPC over HTTPS and WSS — eth_*, net_*, web3_* — and Full and Archive modes on Mainnet.
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.

Run high-volume production workloads with flat monthly billing based on your selected requests per second tier.
Keep infrastructure costs predictable as payment and dApp traffic grows.
Run Celo workloads on production-grade infrastructure with stable latency, predictable capacity, and reliable resources on Chainstack.
“We are pleased to collaborate with Chainstack to make the blockchain experience seamless for users and developers.”
“With Chainstack’s full support we’re excited to keep empowering the Arbitrum ecosystem with infrastructure that will continue to provide for the community.”
“If you need stable node access across multiple chains and you actually need the data to be correct — that's what Chainstack is for.”
“Chainstack was the obvious choice when it comes to scaling our system and improving performance. We’re delighted by the 5-star support we’ve received.”
“Chainstack has been a game-changer for us. Their platform made it a breeze to integrate more than 5 chains into our protocol, providing unparalleled ease and speed.”
"Chainstack is what you see, what you get — enterprise-grade, high performance. It's good to know that Chainstack has got our back."
Get isolated infrastructure for production workloads that require predictable resources, advanced configuration, and consistent performance at scale.
Dedicated Node
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, and the Celo Sepolia Testnet (chain ID 11142220) is available on Global Nodes. 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.
