Moonbeam smart-contracts
In April 2020, the PureStake team announced the Moonbeam smart contract platform, which provides a scalable and affordable alternative to other platform options for developers.
Moonbeam aims to provide developers with the ability to port existing Ethereum DAPPs or create new DAPPs using familiar Ethereum development tools. This will significantly lower the barrier to entry for new and successful Ethereum DAPPs looking to migrate to a more efficient and cost effective platform. Since Moonbeam is based on Substrate, a blockchain development platform from Parity Technologies, we can create our own Ethereum runtime that provides Web3 RPC and EVM implementations to support most Ethereum DAPPs without major changes. Moonbeam's scalability and security are derived from working within Polkadot's segmented design and overall security.
As a parachain on the Polkadot network, Moonbeam will also enable a number of interaction scenarios, including integration with other chains to provide services such as Oracles, DEX, and transfer of tokens from blockchains such as Bitcoin and Ethereum.
Fully compatible with Ethereum and the Polkadot ecosystem
Moonbeam - is much more than just an EVM implementation, it is a highly specialized tier 1 blockchain that mirrors RPCs, accounts, keys, subscriptions, logs, and more Ethereum Web3. The Moonbeam platform extends Ethereum's core feature set with additional features such as chain management, staking, and cross-chain integration.
Solidity smart contracts
Redeploy existing smart contracts in the Polkadot environment without the need for refactoring or rewriting.
Publishing and Subscribing Options
Subscribe to contract events and updates on online transactions, balances and more.
H160 Accounts and ECDSA Signatures
Interact with Moonbeam using your existing Ethereum accounts and keys.
Complete set of Web3 RPC endpoints
Connect existing DAPP tools and interfaces to Moonbeam just like you would to Ethereum.
Moonbeam - as a simple path to multi-chains
Minimal configuration changes
No need to rewrite or reconfigure smart contracts. They will work right away.
Tools you are already using
Use the Ethereum-based tools you like, such as MetaMask, Remix, Hardhat, Waffle, and Truffle.
Familiar smart contract languages
Support for Solidity, Vyper and anything that compiles to EVM bytecode.
Ready integrations
Native integrations for assets like DOT and ERC-20 and infrastructure services like Chainlink and TheGraph.
The future belongs to the multi-chain!
