About this Gig

I will develop a secure KYC gated smart contract using Solidity for DeFi and tokenization platforms.

This gig focuses on ERC20 smart contract development for synthetic assets and compliant blockchain systems. The contract enables users to mint and redeem tokens using real-time on-chain pricing powered by Chainlink oracles.


KYC Smart Contract Features

  • On-chain KYC approval system
  • KYC gated minting and redemption
  • Admin-controlled user access

Token Minting and Buying Logic

  • Mint ERC20 tokens by sending MATIC
  • Automatic pricing using JPY USD and MATIC USD Chainlink feeds
  • Configurable commission fees
  • Safe refund handling

Token Redemption and Burning

  • Burn tokens to redeem MATIC
  • Oracle-based price calculation
  • Liquidity backed redemption system
  • Reentrancy protected withdrawals

️ Admin and Fee Management

  • Adjustable commission in basis points
  • Separate tracking of liquidity and fees
  • Secure admin withdrawals

️ Smart Contract Security

  • Built with OpenZeppelin libraries
  • ReentrancyGuard protection
  • Gas optimized Solidity code
  • Production ready smart contract

Technologies Used

Solidity, ERC20, OpenZeppelin, Chainlink, Hardhat, Polygon, Ethereum
