6. Withdraw an NFT

To withdraw NFT from vault, user should hold `Receipt-NFT` prior. As the `Receipt-NFT` is generated per component-NFT deposition, user can withdraw as many component-NFTs as the user is holding the Receipt-NFTs

How does withdrawal work ?

As we already seen how deposit works, the same happens in the reverse way. When the user tries to withdraw the NFT, the user's wallet address is checked against the stored public in wrapped_user_nft

A count is decreased in the Meta-NFT when a withdraw is successful. If the user withdraws all the component-NFTs from the vault, the Meta-NFT is burnt. The lamports is returned to treasury as revenue to the users.

Withdrawing could be achieved using @kyraa package if you want to implement in your code.

import { depositNft } from '@kyraa/metablocks';

NFTs could also be withdraw from MetaBlocks Program using receiptMint Publickey

const args: WithdrawNftWithReceiptApiArgs = {
  connection: connection,
  receiptMint: pdaKeys.receiptMint, // public key of the receipt mint NFT
  wallet: dummyWallet,
  universeKey: universeKey, // public key of the universe where user deposited NFT
};

await withdrawNftWithReceipt(args);
