According to online reports, Coinbase CEO Brian Armstrong wrote on the X platform that he has received a large number of questions about how and why assets are listed on Coinbase. Guidelines have been written to explain how all this works more transparently. The listing is completely free and based on indicators, all assets are evaluated according to uniform standards. According to Coinbase's Digital Asset Listing Process Guidelines, the application time for listing coins can vary widely, ranging from hours to months, depending on factors such as the complexity of the asset and the integrity of the submission. A complete and well-prepared application is important for effective review and is usually followed: application submission, business evaluation, core review, communication with issuer, and approval.
