Moonbeam is a fully Ethereum-compatible blockchain platform built on Polkadot, designed to facilitate the seamless integration of existing Ethereum applications and developers into the multi-chain Polkadot ecosystem. It simplifies the process of building or migrating decentralised applications by providing Ethereum's smart contract capabilities and tools like MetaMask, but with the added benefits of Polkadot's interoperability and scalability. The platform's native token, GLMR, is used for transaction fees, governance, and network security through staking.
