The Details of Bounty Challenges:

Moonbeam is a smart contract platform for building cross-chain connected applications that can access users, assets, and services on any chain. By uniting functionality from Ethereum, Cosmos, Polkadot and more into a single platform, Moonbeam solves today’s fragmented user experience — unlocking true interoperability and paving the way for the next generation of applications. The Moonbeam platform uses integrated cross-chain messaging to allow developers to create smart contracts that access services across many remote blockchains. This approach, plus Moonbeam’s developer-friendly EVM platform, vast tool support, and modern Substrate architecture, creates the ideal development environment for building connected applications.

Precompiles are solidity interfaces that act as shortcuts to access powerful features. You can interact with a precompile just like you’d call a smart contract. Yet, precompiles can offer features that normal smart contracts simply can’t offer. Moonbeam has a variety of easy-to-use precompiles, many of which expose important Substrate features, such as Staking and Democracy. Moonbeam also has precompiles that enhance the EVM experience, such as batching transactions, or enabling gasless transactions. To qualify for this bounty, you can use ANY Moonbeam precompile to enhance your dApp in any way.

Judging Criteria:

• Some smart contract logic deployed to Moonbeam or Moonbase Alpha
• Use any Moonbeam precompile (a full list is available here: Solidity Precompiles | Moonbeam Docs)
