About D3:
D3 is transforming the $340B+ domain industry into a new financial primitive through DomainFi. This first-ever interoperable network connects traditional domains with Web3 ecosystems to financialize domains as a major asset class. Drawing on over 40 years of combined domain expertise across .com, .net, .org, .xyz, .inc, .tv and 200+ other TLDs, D3 has raised over $30M from top investors including Paradigm and Coinbase Ventures.
Job Overview:
This is a hybrid role in San Francisco or Los Angeles that offers extraordinary creative freedom and ownership in revolutionizing how domains become financialized assets. As Principal Blockchain/Backend Engineer, you will work on the design and implementation of our D3 Protocol connecting traditional DNS and web3 naming technologies to create a unified naming system compatible across the Internet and all blockchains. You will play a critical role in developing and maintaining our core platform APIs and smart contracts supporting multiple L1/L2 blockchains. Familiarity with smart contracts and blockchain standards such as ERC-721, ERC-1155, and ERC-20 is essential.
Responsibilities:
- Collaborate with the product team to understand requirements and translate them into technical specifications and features.
- Lead the research, design, implementation, deployment and monitoring of the D3 Protocol that enables tokenization of domains as Real World Assets (RWAs) onto the blockchain.
- Research, implement and maintain smart contracts to enable “DomainFi” applications across multiple L1/L2 blockchains. This includes tokenization, name resolution, secondary trading, and lending/borrowing.
- Implement backend services to interface with blockchain and traditional DNS Registry/Registrar infrastructure.
- Ensure the scalability, performance, and security of the protocol and application.
- Ensure code quality through code reviews, testing, and debugging.
- Maintain and optimize the performance of existing codebase and address any bugs or issues that arise.
- Stay up-to-date with the latest technologies, frameworks, and best practices in web development, blockchain, and smart contract development.
Qualifications:
- Strong passion for Blockchain technologies and protocols.
- Extensive knowledge and experience in multiple blockchain ecosystems including L1 / L2 chain architectures, smart contract development and deployment, blockchain bridges, oracles, indexers, decentralized finance, and NFT marketplaces.
- Bachelor's degree in computer science, software engineering, or a related field. Relevant certifications and additional coursework are a plus.
- Minimum 5 years of professional experience in backend development using Node.js and MySQL/Postgres.
- Minimum 3 years experience in blockchain development using Solidity/Rust, with strong understanding of distributed systems, consensus algorithms and storage subsystems.
- Familiarity with Git version control and Agile methodologies for collaborative development.
- Strong problem-solving skills, adaptability, and a self-motivated attitude, with a willingness to learn new technologies in a fast-paced startup environment.
- Excellent communication and collaboration skills, with the ability to work effectively both independently and within cross-functional teams to achieve business goals.
Pluses:
- DevOps experience with Kubernetes, Digital Ocean, Google Cloud, AWS, and Linux environments.
- Familiarity with NestJS and GraphQL.
- Have prior experience maintaining or creating blockchain oracles.
Join our dynamic team and be part of the forefront of the domain industry while working with cutting-edge web3 technologies. If you're ready to make an impact, enhance your skills, and contribute to our exciting journey, we would love to hear from you.
To apply, please submit your resume, cover letter, and portfolio (if applicable) showcasing your relevant projects and contributions.
What is ERC20 example?
ERC20 is a standard for fungible tokens on the Ethereum blockchain
Here is an example of an ERC20 token
Let's say we create a new ERC20 token called ABC Token with a total supply of 1,000,000 tokens
Each token will be divisible up to 18 decimal places
To implement the ERC20 standard, we will need to define several functions, including:
- balanceOf(address): Returns the token balance of a specific address.
- transfer(address to, uint256 value): Transfers tokens from the caller's address to the specified address.
- approve(address spender, uint256 value): Approves a specific address to spend a certain amount of tokens on behalf of the caller.
- allowance(address owner, address spender): Returns the amount of tokens approved by the owner that the spender can transfer.
- User1 owns 500,000 ABC Tokens.
- User2 wants to buy 100 ABC Tokens from User1.
- User1 approves User2 to spend up to 100 ABC Tokens on her behalf.
- User2 calls the transferFrom() function with User1's address, his own address, and the value of 100 tokens.
- The transferFrom() function deducts 100 tokens from User1's balance and adds them to User2's balance.
