Coinbase has announced that while it will continue to support trading for Ocean Protocol (OCEAN) and Fetch.ai (FET) tokens, it will not handle user migrations in the upcoming ASI token merger slated for mid-July. Instead, Coinbase encourages users to manage migrations using self-custodial wallets, such as Coinbase Wallet. The ASI merger, involving a consolidation of OCEAN, FET, and SingularityNET (AGIX) into a new token to foster decentralized AI development, contrasts with other major exchanges that will facilitate the token transitions directly.
