We are looking for a Full Stack Software Engineer to join a team of high qualification and technical excellence for one of the most challenging projects in the Bitcoin and FinTech industry worldwide.

RSK (Rootstock) is an open-source, decentralized and peer-to-peer network that brings smart contracts to the Bitcoin ecosystem. It is the first one to provide the possibility of running Ethereum smart contracts in Bitcoin, using bitcoin as its native cryptocurrency, and leveraging Bitcoin's hashing power. RSK is one of the most exciting projects in the crypto and blockchain space!

The RSK Interoperability team is responsible for building services and protocols that will integrate RSK with other crypto economies, such as Ethereum or Binance Chain. It maintains and evolves bridges that let users transfer assets (ERC-20 tokens, NFTs, etc) back and forth between RSK and other blockchains, giving Dapp developers the ability to bring their token-based services to the RSK ecosystem.

IOV Labs embraces diversity and is proud to be an equal opportunity employer open to all qualified applicants regardless of race, color, ancestry, religion, sex, national origin, sexual orientation, age, citizenship, marital status, disability, gender identity or expression, Veteran status, or any other legally protected status.

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:

  1. balanceOf(address): Returns the token balance of a specific address.
  2. transfer(address to, uint256 value): Transfers tokens from the caller's address to the specified address.
  3. approve(address spender, uint256 value): Approves a specific address to spend a certain amount of tokens on behalf of the caller.
  4. allowance(address owner, address spender): Returns the amount of tokens approved by the owner that the spender can transfer.
  5. User1 owns 500,000 ABC Tokens.
  6. User2 wants to buy 100 ABC Tokens from User1.
  7. User1 approves User2 to spend up to 100 ABC Tokens on her behalf.
  8. User2 calls the transferFrom() function with User1's address, his own address, and the value of 100 tokens.
  9. The transferFrom() function deducts 100 tokens from User1's balance and adds them to User2's balance.
