Solidity Smart Contracts on Polkadot

Moonbeam Smart Contracts on Polkadot Logo

A Polkadot Parachain
Designed for Developers

Moonbeam simplifies the developer experience by combining full Ethereum compatibility with the power of Polkadot, including scalability, cross-chain integrations, and on-chain governance.

See Moonbeam's Launch Sequence

Simplified Deployments

Write your smart contracts in anything that compiles to Solidity bytecode, without needing to rewrite or reconfigure.

Broad Tool Compatibility

Leverage Ethereum’s broad development ecosystem by using the tools you love, like MetaMask, Hardhat, Waffle, Remix, and Truffle, in addition to Substrate-based APIs.

Pre-Built Integrations

Built-in integrations for assets like DOT and ERC-20s and infrastructure services like Chainlink and TheGraph. Continual efforts to integrate with other Polkadot-native assets, like the Acala Dollar.

The Best of Both Worlds

The Power of Polkadot.
The Ease-of-Use of Ethereum.

Moonbeam delivers complete Ethereum compatibility within a Polkadot parachain environment, so developers can continue to use the programming languages and tools they’ve grown used to — but within a fast-growing and scalable Layer 1 chain.

It is also compatible with the Substrate and Polkadot ecosystem, including block explorers, wallets, parachains, and more, allowing users the flexibility to choose the right tools and services for the job.

An Easy On-Ramp to Polkadot

Moonbeam is so much more than a “bridge:” it’s a launchpad for applications that want to tap into Polkadot’s success without hefty code rewrites. Use the Moonbeam platform to redeploy your Solidity smart contracts to a parallel instance — with little or no changes.

Redeploy existing Solidity smart contracts using favorite tools like Hardhat, Waffle, Remix, Truffle, or Ether.js/Web3.js.
Easily expand to Moonbeam and gain easy access to the growing userbase and ecosystem on Polkadot.
Maintain existing deployments to other chains, which will eventually be connected via bridges.
Move wrapped tokens between Moonbeam and other parachains via bridges. The development of multiple bridges are currently underway.

Complete Ethereum Compatibility

Moonbeam is a full Ethereum-like environment and works with industry-standard  Ethereum tools, DApps, and protocols.

By mirroring Ethereum’s Web3 RPC, accounts, keys, subscriptions, logs, and more, Moonbeam minimizes the changes required to run existing Solidity smart contracts on the network. Ethereum projects can simply replicate their DApp and deploy it to Moonbeam using popular deployment tools.

The Moonbeam platform also extends the base Ethereum feature set with additional features such as on-chain governance, staking, and cross-chain integrations.

Here’s how the Moonbeam platform goes beyond basic EVM compatibility:

Unified Accounts, Addresses, and Signatures:

Use your existing Ethereum-like H160 accounts & ECDSA signatures to interact with Moonbeam.

Use Existing Tools and DApp Front-Ends:

Connect popular tools like MetaMask, Hardhat, Waffle, Remix, and Truffle via a complete set of Web3 RPC endpoints. Use well known Javascript libraries such as Web3.js or Ethers.js.

Deploy with Minimal Changes:

If you have an existing contract, it will work right away with no need to rewrite or reconfigure.

Use Familiar Programming Languages:

Write smart contracts in Solidity or anything that compiles to Solidity bytecode.

Glimmer Token

The Utility Token of the Moonbeam Network

As a decentralized smart contract platform, Moonbeam requires the Glimmer token to function.

Some of the uses of the Glimmer token on Moonbeam include:

  • Supporting the gas metering of smart contract execution
  • Incentivizing collators and powering the mechanics around the creation of a decentralized node infrastructure on which the platform can run
  • Facilitating the on-chain governance mechanism including proposing referenda, electing council members, voting, etc
  • Paying for transaction fees on the network

More information about distribution, supply, and other token economic behaviors can be found on the Moonbeam Foundation website.
