If you bought an NFT from a drop you might need to wait until transaction was successfully processed. This can take sometimes a couple of minutes if the blockchain is really busy. If your transaction does not get processed, it might be that your initial transaction failed. In that case you have not lost any funds and you can try again to buy the NFT of your choice. Please check in your wallet if the transaction was successful or not. If you still cannot manage to find your NFT please contact us at feedback@enefty.app
