Moonbeam RPC Endpoint

Fast, flat-rate Moonbeam RPC node provider — free tier, no KYC, HTTP & WebSocket.

Moonbeam is an Ethereum-compatible smart contract parachain on Polkadot, designed for cross-chain applications. It pairs full EVM compatibility with Polkadot's shared security and cross-consensus messaging (XCM).

About Moonbeam

Moonbeam launched on Polkadot on January 11, 2022 as one of the first fully operational parachains. It uses collators to author blocks via the Nimbus framework and inherits finality from Polkadot's relay chain validators. Block times are roughly 6 seconds following Polkadot's asynchronous backing upgrade.

Moonbeam exposes a standard Ethereum JSON-RPC and Web3 interface, so developers use Solidity, Hardhat, Foundry, ethers.js, and MetaMask without changes. Its native token GLMR (Glimmer) pays for gas and is used in staking and governance, while XCM enables asset and message transfers with other Polkadot parachains.

Common Use Cases on Moonbeam

• Cross-chain DeFi via Polkadot XCM
• EVM smart contract deployment
• Multi-chain dApp connectivity
• GLMR staking and on-chain governance
• Bridged asset liquidity

Moonbeam Ecosystem

Hosts DeFi and infrastructure such as StellaSwap, Moonwell, and integrations with Chainlink and The Graph, plus XCM connections to other Polkadot parachains.
