Question 1

What is an RPC endpoint for Mantle?

Accepted Answer

An RPC (Remote Procedure Call) endpoint is a URL that allows your application to communicate with the Mantle blockchain. Through RPC endpoints, you can read blockchain data, submit transactions, query account balances, and interact with smart contracts without running your own Mantle node.

Question 2

What are the best free Mantle RPC endpoints?

Accepted Answer

RPC Directory lists multiple free public Mantle endpoints you can use for development and low-traffic applications. Public endpoints are rate-limited and may experience downtime during high traffic. For production applications, consider using a paid RPC provider for better reliability and higher rate limits.

Question 3

What is the Mantle chain ID?

Accepted Answer

The Mantle Testnet chain ID is 5001. This unique identifier is used by wallets like MetaMask to connect to the correct network and prevent transaction replay attacks between different EVM chains.

Question 4

How do I add Mantle to MetaMask or other wallets?

Accepted Answer

To add Mantle Testnet to your wallet, use our one-click wallet integration at /add - it works with MetaMask, Rainbow, Coinbase Wallet, and other popular wallets. Or manually: 1) Open your wallet and find the network settings. 2) Click "Add Network". 3) Enter the network name "Mantle Testnet", RPC URL (copy one from this page), Chain ID "5001", and currency symbol "ETH". 4) Save.

Question 5

How do I connect to Mantle with ethers.js or web3.js?

Accepted Answer

To connect with ethers.js: `const provider = new ethers.JsonRpcProvider("YOUR_RPC_URL")`. For web3.js: `const web3 = new Web3("YOUR_RPC_URL")`. Replace YOUR_RPC_URL with any endpoint from this page. For production, use a provider with an API key for better rate limits.

Question 6

How do I get free Mantle testnet tokens?

Accepted Answer

Mantle Testnet testnet tokens can typically be obtained from community faucets or by requesting them in the official Discord/Telegram channels. Testnet tokens have no real value and are only for testing purposes.

Question 7

What's the difference between Mantle mainnet and testnet?

Accepted Answer

Mantle mainnet is the production network where real transactions with actual value occur. Testnets like Testnet are testing environments with tokens that have no real value. Always test your applications on testnet before deploying to mainnet to avoid costly mistakes.

Question 8

What's the difference between free and paid Mantle RPC providers?

Accepted Answer

Free public endpoints have rate limits (typically 10-100 requests/second), may experience downtime during high traffic, and offer limited features. Paid providers offer higher rate limits (1000+ RPS), better reliability with SLAs, additional features like archive data access, WebSocket connections, and dedicated support. Use the pricing calculator above to compare costs.

Question 9

Does Mantle support WebSocket connections?

Accepted Answer

Many Mantle RPC providers offer WebSocket (WSS) endpoints for real-time subscriptions to new blocks, pending transactions, and contract events. WebSocket connections are ideal for applications that need instant updates without polling. Check the endpoints list above for available WSS URLs.
