About Telcoin

Telcoin is a dynamic fintech company dedicated to revolutionizing the global remittance industry through blockchain technology. As a pioneer in the field, Telcoin combines the power of cryptocurrencies with telecommunications infrastructure to provide fast, secure, and low-cost banking and finance solutions to users worldwide.

Position Overview

We are seeking an experienced Solidity developer to join our innovative team as a contractor on a 4-6 month project. This role is crucial for developing and deploying smart contracts on our proprietary Layer 1 blockchain, Telcoin Network. The ideal candidate will take full ownership of the design and implementation process, working closely with our blockchain engineering team to integrate ERC-20 tokens as native tokens and manage validator staking mechanisms.

Key Responsibilities:

  • Smart Contract Development: Design, build, and maintain advanced smart contracts on Solidity. Take the lead on developing a bridge for Telcoin’s ERC-20 token from Ethereum to our Layer 1 blockchain, considering solutions like Axelar and General Message Passing.
  • Token Integration: Integrate the bridged ERC-20 asset as the native token of our Layer 1 blockchain, analogous to how MATIC functions on Polygon, ensuring stability and security in token management.
  • Staking Contract: Develop a permissioned validator staking contract accessible only to accounts holding a specific governance-issued NFT. This includes handling staking mechanisms, reward issuance, and ensuring secure and efficient on-chain transactions.

Audit: Work with external auditors to ensure the highest level of security and transparency.

Requirements:

  • Proven experience in Solidity and smart contract development.
  • Familiarity with blockchain bridging technologies and protocols.
  • Deep knowledge of proof of stake consensus mechanisms
  • Strong understanding of cryptography, side-chains, bridging solutions, and blockchain fundamentals.
  • Excellent problem-solving skills and ability to work independently.
  • Experience with permissioned blockchain systems and NFTs is highly desirable.

Nice to haves:

  • Familiarity with Polygon, Cosmos, Axelar, and General Message Passing (CCIP/CCTP, Wormhole, etc.)
  • Participation with a project that launched a side-chain or Layer 2 solution.
  • Insight on the integration between smart contracts and blockchain state.
  • Web3 experience and/or open-source contributions are preferred.

Location: Remote

How to Apply

If you're passionate about blockchain technology and eager to make a meaningful impact in the fintech industry, we'd love to hear from you! Please submit your resume and a cover letter detailing your relevant experience and why you're interested in joining Telcoin Network's team.

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.
