The code seems to be mostly correct, but there is a small error in the pragma statement. The correct pragma statement for the version 0.8.20 of Solidity is pragma solidity ^0.8.0;. Here's the corrected code:

// SPDX-License-Identifier: BSD-3-Clause

pragma solidity ^0.8.0;

import {ERC20Initializable} from "./lib/ERC20Initializable.sol";

/**

• @title MCV2_Token

• @dev A token contract that implements a bonding curve and allows minting and burning of tokens.
  */
  contract MCV2_Token is ERC20Initializable {
  error MCV2_Token__AlreadyInitialized();
  error MCV2_Token__PermissionDenied();

  bool private _initialized; // false by default
  address public bond; // Bonding curve contract should have its minting permission

  /**

  • @dev Initializes the token contract with the provided name and symbol.

  • @param name_ The name of the token.

  • @param symbol_ The symbol of the token.
    */
    function init(string calldata name_, string calldata symbol_) external {
    if(_initialized) revert MCV2_Token__AlreadyInitialized();
    _initialized = true;

    name = name;
    symbol = symbol;
    bond = _msgSender();
    }

  modifier onlyBond() {
  if (bond != _msgSender()) revert MCV2_Token__PermissionDenied();
  _;
  }

  /**

  • Minting should also provide liquidity to the bonding curve contract.
  • @param to The address to which the minted tokens will be transferred.
  • @param amount The amount of tokens to mint.
    */
    function mintByBond(address to, uint256 amount) external onlyBond {
    _mint(to, amount);
    }

  /**

    */
    function burnByBond(address account, uint256 amount) external onlyBond {
