Fractional provides ownership of the world’s most sought after NFTs! Working at Fractional, you will be building on the cutting edge of NFTs and DeFi to help shape the future of collecting NFTs. You will get to work, learn and grow with an experienced team supported by incredible partnerships and committed investments from developers, collectors, investors, and thought leaders who are deeply passionate about the decentralization ecosystem.
More practically, Fractional is a decentralized, permission-less protocol where NFT owners can mint tokenized fractional ownership of their NFTs. These tokens then function as normal ERC20 tokens and the owners can distribute them however they would like. You can read more from our medium posts here: https://medium.com/fractional-art
About the role:
As a Rust smart contract engineer, you will be responsible for supporting the build of a range of new developments, aspects, and technical enhancements to the fractional protocol on Solana, which may include:
Mechanism and modular smart contract designs
Building layer 2 scaling integrations, such as support for Polygon, Optimism, and Arbitrum
Bridging support for other networks non-EVM (e.g., Flow/Cadence, Solana/Rust)
Developing new smart contracts not yet hypothesized
Our fast-paced, agile development environment will require a penchant for task management and respect for efficient, best practice development principles as well!
Our Evolving Tech Stack
Front End: HTML, CSS, JS, Vue.js
Back End: Redis, MySQL, Node.js
Infrastructure: DigitalOcean, AWS (S3), Cloudfront
Automated testing: ~under construction~
Web3: Solidity/Ethereum, Cadence/Flow, Rust/Solana [Upcoming]
Integrations: browser-based crypto wallets such as MetaMask, APIs
If you’re convinced you are the right fit and you can’t wait to join our team, we look forward to hearing from you!
Once you've applied, please be patient :) it may take us up to 1-2 weeks to get back to you!
Please kindly include a link to your github as well!
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.
