QVM - Quantum Virtual Machine

.q is the native QVM language with first-class DeFi support, automatic overflow protection, and built-in post-quantum cryptographic primitives

Example: QRC20 Token in .q

contract MyToken : QRC20 {
  string public name = "My Token";
  string public symbol = "MTK";
  uint256 public totalSupply = 1000000;

  // Автоматическая защита от переполнения
  function transfer(address to, uint256 amount) public returns (bool) {
    require(balances[msg.sender] >= amount, "Insufficient balance");

    balances[msg.sender] -= amount;  // Safe math встроен
    balances[to] += amount;

    emit Transfer(msg.sender, to, amount);
    return true;
  }

  // Нативная поддержка постквантовых подписей
  function transferPQ(address to, uint256 amount, bytes pqSignature) public {
    require(PQ_VERIFY_DILITHIUM(msg.sender, pqSignature), "Invalid PQ signature");
    transfer(to, amount);
  }
}

Example: DEX Contract with Native Primitives

contract SimpleDEX {
  mapping(address => uint256) public liquidityETH;
  mapping(address => uint256) public liquidityToken;

  // Использование нативного опкода DEFI_SWAP (0xE0)
  function swap(address tokenIn, uint256 amountIn) public returns (uint256) {
    // AMM формула x*y=k встроена в опкод
    uint256 amountOut = DEFI_SWAP(tokenIn, amountIn);

    emit Swap(msg.sender, tokenIn, amountIn, amountOut);
    return amountOut;
  }

  // Использование ADD_LIQUIDITY (0xE1)
  function addLiquidity(uint256 amountETH, uint256 amountToken) public {
    uint256 lpTokens = ADD_LIQUIDITY(amountETH, amountToken);

    liquidityETH[msg.sender] += amountETH;
    liquidityToken[msg.sender] += amountToken;

    emit LiquidityAdded(msg.sender, lpTokens);
  }

  // Использование ORACLE_PRICE (0xE6) для получения цены
  function getPrice(address token) public view returns (uint256) {
    return ORACLE_PRICE(token);
  }

  // Flash loan с нативным опкодом FLASH_LOAN (0xE3)
  function flashLoan(uint256 amount) public {
    FLASH_LOAN(amount, address(this));
    // Логика flash loan
    // Автоматически проверяется возврат + 0.09% комиссии (9 BPS)
  }
}
