Seeking strong Smart Contract Developers to support building the next iteration of extensible smart contracts ecosystem. In this role, you will be responsible for supporting the build of a range of new developments, aspects, and technical enhancements to the existing smart contracts as well as creating smart contracts that provide entirely new functionality.
Key Responsibilities
- Work on how to gamify the NFT collecting experience
- Implement token (ERC721) fractionalisation functionality
- Work on "DAO as a service solutions
- Build layer 2 scaling integrations, such as support for Polygon
- Bridging support for other networks not solidity-based (e.g., Flow, Solana/Rust)
- Developing new smart contracts not yet hypothesized
- Make a HUGE impact helping to turn ideas into code
- Work within a dynamic team, who challenges the status quo and champion agile working and continuous improvement
Qualifications
- 2+ years of experience with Solidity or other smart contract languages
- Strong knowledge of TypeScript (we use it to test smart contracts)
- Understanding of the Ethereum Virtual Machine
- Prior experience in deploying smart contract systems to the
- Familiar with Web3 frameworks and tools such as OpenZeppelin (https://openzeppelin.com/contracts/), Infura (https://infura.io/), ethers.js (https://docs.ethers.io/v5/) is a plus
- Understanding of various DeFi protocols
- Experience in communicating with users, other technical teams, and product management to understand requirements, describe software product features, and technical designs
- Ability to derive the information from a research paper, whitepaper, technical paper, litepaper, etc.
- Experience with agile and test-driven development
- Solidity code deployed to mainnet and used Truffle
- Experience with NFT platforms
Preferred, But Not Required

- Full-stack capabilities
- Experience with EIPs and structuring proposals
- Accomplished with TypeScript and building web JavaScript libraries for Dapps
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:
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Impact on User Experience: For end-users, Layer 2 solutions can greatly improve the experience by reducing transaction fees and increasing transaction speeds.
- 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.
