Who we are

Mantle Network is a high-performance Ethereum Virtual Machine (EVM) modular L2 network incubated by the BitDAO community. Mantle Network’s modular rollup architecture separates transaction execution, data availability, and transaction finality. As the first L2 network partner for restaking protocol EigenLayer, Mantle Network directly inherits security from Ethereum while offering high performance at low fees.

As the world’s first DAO-led L2 network, Mantle Network is pioneering a vision for a more collaborative decentralized economy to showcase the potential of tokenized governance. Our mission is to revolutionize the blockchain industry by providing scalable, efficient, and secure solutions for decentralized applications.

Your Role

  • Collaborate with cross-functional teams to understand project requirements and translate them into well-structured and efficient smart contracts.

  • Implement, test, and deploy smart contracts on various blockchain platforms

  • Write clean, maintainable, and well-documented code for smart contracts.

  • Conduct comprehensive security audits of smart contracts to identify vulnerabilities and ensure they meet the highest security standards.

  • Stay up-to-date with the latest security threats and best practices in blockchain security to proactively address potential issues.

  • Continuously optimize existing smart contracts for gas efficiency, performance, and scalability.

  • Identify bottlenecks and propose improvements to enhance contract execution speed and resource utilization.

  • Develop and execute test cases to validate the functionality and security of smart contracts.

  • Collaborate with DevOps teams for the seamless deployment of contracts onto the blockchain.

  • Maintain comprehensive documentation for all smart contracts, including design decisions, coding standards, and usage instructions.

Your Craft

  • Proficient in blockchain fundamentals with an in-depth understanding of Ethereum, Account Model, and EVM.

  • Familiar with the technical principles and implementations of DeFi-related contracts such as Uniswap and Lido.

  • Mastery of Solidity smart contract language for development, testing, and optimization.

  • Proficient in smart contract development tools such as Foundry and Hardhat.

  • Proficiency in one or more programming languages, such as Golang and JavaScript.

  • Preferred experience in one or more of the following:

    • Practical development and deployment experience in DeFi projects.

    • Experience in developing and implementing Ethereum Op-Rollup and ZK-Rollup solutions.

    • Background in cryptography with unique insights into blockchain and smart contract security.

    • Contributions to open-source security contract libraries like Ethereum and OpenZeppelin.

    • Candidates should have a full-time bachelor's degree or higher in a computer-related field.

What is the meaning of Layer 2?

Layer 2 in the context of cryptocurrency and blockchain technology refers to a secondary framework or protocol that is built on top of an existing blockchain system (the main chain or Layer 1)

The primary purpose of Layer 2 solutions is to solve the scalability and speed issues that many blockchains face, especially those that have become popular and heavily used, like Ethereum

Here are the key aspects of Layer 2 solutions:

  1. Scalability Enhancement: They help in scaling the main blockchain by handling transactions off the main chain. This reduces the burden on the main chain, allowing for faster and cheaper transactions.
  2. Types of Layer 2 Solutions: There are various forms of Layer 2 solutions, including state channels, sidechains, plasma chains, and rollups. Each has its own mechanism for interacting with the main chain and handling transactions.
  3. State Channels: These involve two parties engaging in numerous transactions outside of the main chain, which are then consolidated into a single transaction. This is especially useful for situations where multiple transactions occur between the same parties.
  4. Sidechains: These are separate blockchains that are connected to the main chain via a two-way peg. They operate independently and can have their own consensus mechanisms but are secured by the main chain.
  5. Plasma Chains: Plasma chains are similar to sidechains but with a more hierarchical structure. They report back to the main chain regularly and are optimized for mass transaction handling.
  6. Rollups: Rollups process and store transaction data on a sidechain but post transaction data to the main chain. They come in two varieties: optimistic rollups and zk-rollups, each with its own method of transaction verification.
  7. Security Considerations: While Layer 2 solutions are generally secure, they can have different security models compared to the main chain. This is an important consideration for users and developers.
  8. Impact on User Experience: For end-users, Layer 2 solutions can greatly improve the experience by reducing transaction fees and increasing transaction speeds.
  9. Adoption and Development: Many blockchain projects are actively developing Layer 2 solutions to enhance their networks. This is an ongoing area of innovation in the blockchain space.
