SongVault

The SongVault contract permanently locks NFTs when trading is enabled.

Purpose​

When a creator enables trading:

  1. NFT transferred to vault (permanent)
  2. ERC-20 tokens minted
  3. Uniswap pool created

Why Permanent?​

The vault has no unlock mechanism because:

  • AMM math makes 100% buyback impossible
  • Prevents rug pulls
  • Ensures token value is backed

Interface​

interface ISongVault {
    function enableTrading(uint256 tokenId) external;

    function getLockedNFT(uint256 tokenId) external view returns (bool isLocked);

    function getSongToken(uint256 tokenId) external view returns (address);
}

Enable Trading Flow​

function enableTrading(uint256 tokenId) external {
    // 1. Verify ownership
    require(songNFT.ownerOf(tokenId) == msg.sender, "Not owner");

    // 2. Transfer NFT to vault
    songNFT.transferFrom(msg.sender, address(this), tokenId);

    // 3. Deploy token
    address token = _deploySongToken(tokenId);

    // 4. Create Uniswap pool
    _createPool(token);

    // 5. Distribute tokens
    _distributeTokens(token, msg.sender);
}

Events​

event NFTLocked(uint256 indexed tokenId, address indexed previousOwner);
event TokenDeployed(uint256 indexed tokenId, address tokenAddress);
event PoolCreated(uint256 indexed tokenId, address poolAddress);
