Mantle RPC Endpoint

Flat-rate Mantle RPC provider and Mantle RPC node access: free tier, no KYC, HTTP & WebSocket. Mantle mainnet chain ID 5000.

Mantle is a modular Ethereum Layer 2 that separates execution, settlement, and data availability. It uses EigenDA for data availability — the first major L2 to do so — significantly reducing data costs compared to chains that post calldata to Ethereum.

About Mantle

Mantle launched mainnet in July 2023 (initially as BitDAO's L2 initiative, later rebranded). The modular architecture (EVM execution, Ethereum settlement, EigenDA data availability) allows Mantle to offer lower fees than typical L2s while inheriting Ethereum security for settlement.

Mantle has one of the largest L2 ecosystem treasuries, originally from BitDAO. The treasury funds incentive programs, liquidity provisioning, and ecosystem development. mETH (Mantle Staked ETH) is a liquid staking token that integrates with Mantle's broader ecosystem.

Common Use Cases on Mantle

• DeFi with sub-cent fees (FusionX, Agni, Lendle)
• Liquid restaking integrations (mETH ecosystem)
• Cross-chain applications with modular data availability
• Treasury-funded ecosystem projects
• Stablecoin yield optimization

Mantle Ecosystem

FusionX, Agni (DEXes), Lendle, INIT Capital (lending), mETH liquid staking. The Mantle Treasury is one of the largest crypto ecosystem treasuries, deployed across grants and liquidity programs.

Mantle guides from the blog

• Mantle RPC: Endpoints, EigenDA, and What's DifferentMantle looks like a standard EVM L2 until two things trip you up: gas is paid in MNT, not ETH, and data availability runs through EigenDA instead of Ethereum calldata. Here's what that means for your RPC calls, plus the Mantle endpoints to point at.
