According to Ouyi official news, Ouyi NFT market has launched the first Bitcoin Ordinal NFT collection - Bitcoin Punks, which is a custodial certificate NFT packaged through the escrow tool EmblemVault. After the buyer purchases the certificate of custody, the seller loses control of the original Bitcoin NFT. The buyer can continue to place an order to sell, or go to EmblemVault to withdraw the NFT to his own BTC wallet. The Bitcoin Punks collections in the Ouyi NFT market are all real NFTs that have passed the security verification of Ouyi OKX. Users can use ETH or other ERC20 tokens to freely trade BTC NFTs through this collection, avoiding asset losses caused by purchasing fake NFTs or private transactions.
