Fantom RPC Endpoints

Fantom is a fast, high-throughput open-source smart contract platform for digital assets and decentralized applications (dApps). Its Opera mainnet uses a Directed Acyclic Graph (DAG) consensus mechanism called Lachesis, enabling near-instant finality and low transaction costs. Developers building on Fantom need reliable RPC endpoints to interact with the blockchain.

What is a Fantom RPC Endpoint?

A Fantom RPC endpoint is a network URL that applications use to read blockchain data, submit transactions, and connect backend services to the Fantom network. It follows the EVM JSON-RPC standard, making it compatible with Ethereum tooling like MetaMask, Hardhat, and Web3.js.

Why Use OnFinality for Fantom RPC?

OnFinality provides managed Fantom RPC endpoints with archive data support, request analytics, and a clear scaling path from shared APIs to dedicated nodes. This allows developers to focus on building rather than maintaining node infrastructure.

Archive Access: Query historical state data without running your own archive node.
Observability: Monitor request usage, errors, and latency through the OnFinality dashboard.
Scalability: Start with shared endpoints and upgrade to higher capacity as your project grows.

Create or sign in to your OnFinality account.
Select Fantom from the supported networks list.
Create an API endpoint (or deploy a dedicated node if needed).
Test the endpoint using eth_blockNumber.
Monitor usage and limits before moving production traffic.

Fantom RPC Use Cases

DeFi Protocols: Fetch token balances, submit swaps, and monitor liquidity pools.
Wallets: Broadcast transactions and retrieve account history.
Analytics Tools: Index on-chain data for dashboards and reporting.
Games & NFTs: Mint assets, track ownership, and process in-game transactions.

Public vs Private Fantom RPC

Public endpoints are suitable for lightweight testing but often lack reliability and visibility for production workloads. OnFinality's authenticated endpoints provide clearer usage limits, request analytics, and dedicated support options.
