NFTs are subject to withdrawal holds. Certain deposits, such as first time ACH purchases, digital wallet, or debit/credit card purchases, will trigger a withdrawal hold for security purposes. If you do not have enough collateral in your account to satisfy the hold amount, one or more of your NFTs may be subject to a withdrawal hold. This means they cannot be withdrawn until the hold expires. Holds generally last 72 hours or up to 7 days depending on hold type. Learn more about withdrawal holds here.
