# Moonbeam (GLMR)

GetBlock provides fast and reliable access to Moonbeam nodes via JSON-RPC API. Connect to the Moonbeam network without running your own infrastructure.

Moonbeam is an EVM-compatible smart contract parachain on Polkadot, built with Substrate and the Frontier EVM layer. It mirrors Ethereum's JSON-RPC API, so Solidity contracts, the `eth_*` surface, and tooling such as Foundry, Hardhat, Ethers.js, and Viem work unchanged, while the chain inherits shared security and deterministic finality from Polkadot's relay chain. Moonbeam uses unified Ethereum-style (H160) accounts — a single `0x` address per account, with no separate Substrate address to manage — and exposes Substrate functionality (staking, XCM, batching, native-asset ERC-20s) to Solidity through on-chain precompiles. The native gas token is GLMR, and Moonbeam supports EIP-1559 fee-market pricing.

### Key Features

* **EVM Compatibility**: Ethereum contracts, JSON-RPC, and tooling run unchanged on the Frontier EVM layer
* **Polkadot Parachain**: Shared relay-chain security and deterministic finality from Polkadot
* **Unified H160 Accounts**: One Ethereum-style address per account — no separate Substrate/EVM address split
* **Substrate Precompiles**: Staking, XCM, batch, and native-asset ERC-20 features are callable from Solidity via precompiles
* **EIP-1559 Fees**: Base-fee pricing with `eth_feeHistory` and priority fees; native token GLMR (18 decimals)
* **Ethereum Tooling**: Compatible with MetaMask, Foundry, Hardhat, Remix, Ethers.js, and Viem
