Moonbeam Network

Introduction

Moonbeam is an Ethereum-compatible smart contract parachain on Polkadot.

Moonbeam is much more than just an EVM implementation: it’s a highly specialized Layer 1.5 chain that mirrors Ethereum’s Web3 RPC, accounts, keys, subscriptions, logs, and more. The Moonbeam platform extends the base Ethereum feature set with additional features such as on-chain governance, staking, and cross-chain integrations.

Appendix

Moonbeam token

The Moonbeam token GLMR is the native token of the Moonbeam network. This is similar to Ether in Ethereum. To interact with the Moonbeam network, GLMR tokens are required to pay gas fees. The Covalent API response returns gas_* fields in fiat units.
