What is Celo?

Celo is a carbon-negative, mobile-first, EVM-compatible blockchain ecosystem designed to make Web3 universally accessible. It focuses on enabling a thriving digital economy for all, with seamless composability and efficient project scaling. Celo uses a proof-of-stake consensus and is fully compatible with Ethereum tooling, allowing developers to deploy Solidity smart contracts and use standard Ethereum JSON-RPC methods.

Why Use a Celo RPC Endpoint?

A Celo RPC endpoint is a network URL that applications use to read blockchain data, submit transactions, and connect backend services to Celo. Developers building dApps, wallets, DeFi products, analytics tools, games, bots, or backend services need reliable RPC access to interact with the Celo blockchain without running their own node.

Celo RPC on OnFinality

OnFinality provides managed Celo RPC endpoints with archive access, enabling developers to query historical state and event logs. Our infrastructure supports production workloads with clear usage limits, request analytics, and a path to higher capacity. Key features include:

EVM JSON-RPC Protocol: Full compatibility with Ethereum tools and libraries.
HTTP Transport: Simple integration with any HTTP client.
Archive Access: Query historical data for analytics, audits, and more.
Scalable Plans: From shared endpoints to dedicated nodes where supported.

How to Connect to Celo with OnFinality

Create or sign in to an OnFinality account.
Choose Celo from the supported networks list.
Create an API endpoint or deploy a dedicated node if the network supports it.
Test the endpoint with the example method eth_blockNumber.
Monitor request usage, errors, and limits before moving critical traffic.

Public vs Private Celo RPC

Public endpoints like Forno are useful for quick tests but are rate-limited and shared. OnFinality endpoints provide authenticated access, clearer limits, request visibility, and a scaling path for production applications.
