Mantle RPC Endpoints & API on OnFinality

Mantle is an Ethereum layer-2 scaling solution built with a modular architecture. It combines an EVM-compatible execution layer with Ethereum's security and a decentralized data availability layer (Mantle DA) to deliver low fees and high throughput. Developers building on Mantle need reliable RPC endpoints to interact with the network—reading blockchain data, submitting transactions, and connecting backend services.

OnFinality provides managed Mantle RPC endpoints and API access, so you can focus on building dApps, wallets, DeFi protocols, analytics tools, games, and bots without running your own node infrastructure.

What is a Mantle RPC Endpoint?

A Mantle RPC endpoint is a network URL that applications use to communicate with the Mantle blockchain. It supports standard Ethereum JSON-RPC methods, making it easy to use familiar tools like ethers.js, web3.js, and Hardhat. OnFinality offers both HTTP and WebSocket endpoints for real-time and request-response interactions.

Key Features of OnFinality Mantle RPC

Mainnet access: Connect to Mantle mainnet with authenticated endpoints.
Archive support: Access historical state data for analytics and backfilling.
EVM JSON-RPC: Full compatibility with Ethereum development tools.
Observability: Request analytics and usage metrics to monitor your application.
Scalable plans: From shared endpoints to higher-capacity options as your project grows.

How to Connect to Mantle with OnFinality

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

Public vs. Private Mantle RPC

Public Mantle RPC endpoints are convenient for quick testing but often have rate limits and no guaranteed performance. OnFinality's authenticated endpoints provide clearer usage limits, request analytics, and a path to higher-capacity infrastructure—essential for production workloads.

Use Cases for Mantle RPC

dApps: Read contract state, send transactions, and listen to events.
Wallets: Fetch balances, transaction history, and submit transfers.
DeFi: Interact with liquidity pools, oracles, and lending protocols.
Analytics: Query historical data via archive nodes.
Backend services: Automate on-chain operations and monitoring.
