Coinbase's asset management division launched the Coinbase Bitcoin Yield Fund (CBYF) in May 2025, aimed at providing institutional investors with a net Bitcoin yield of 4-8%. However, recent claims that the fund has migrated to the Base blockchain and launched tokenized shares have not been confirmed by any official documents from Coinbase or on-chain data.
According to Coinbase, the fund is only open to non-U.S. investors and supports its investment strategy through qualified custodians and third-party custody integration. In May 2025, Apex Group confirmed it was selected to provide digital fund management services for the fund. The initial capital for the fund was injected by several institutional investors, including Aspen Digital, with Coinbase estimating its assets under management (AUM) capacity at around $1 billion.
Rumors of Migration to Base Chain Lack Direct Evidence
As of March 20, 2026, rumors circulating on social media suggested that Coinbase would migrate CBYF to the Base blockchain and issue tokenized shares. However, there has been no official announcement from Coinbase, Base, Apex Group, or related tokenization partners confirming this migration. Additionally, there are no filing documents, fund documents, token contract addresses, or protocol dashboards that can substantiate the existence of on-chain shares for CBYF.
To verify this rumor, investors and journalists would need at least one of the following pieces of evidence: an official statement from Coinbase or Base, filing documents from the U.S. Securities and Exchange Commission (SEC) or the Cayman Islands Monetary Authority (CIMA) mentioning the tokenized share structure, or a verifiable smart contract on the Base chain that can be linked to CBYF's fund management services.
Potential Impact of Tokenized Shares
If Coinbase indeed tokenizes CBYF shares and issues them on the Base chain, it would have a substantial impact on Bitcoin yield products. Tokenized fund shares would enable secondary market trading, meaning institutional holders could trade their positions without waiting for traditional redemption windows. Furthermore, on-chain shares could serve as collateral in decentralized finance (DeFi News) lending markets, enhancing capital efficiency, which is difficult to achieve with traditional fund structures.
For a product priced in BTC, with subscriptions and redemptions also conducted in Bitcoin, adding a layer of tokenized issuance on the Base chain would create a native digital distribution channel. However, any tokenized CBYF shares would still need to comply with existing securities and fund management regulations. Coinbase's U.S. advisory entity is registered with the SEC and the Commodity Futures Trading Commission (CFTC), while its Cayman subsidiary holds an asset management license from CIMA. Therefore, when issuing tokenized shares on-chain, requirements such as the transfer of control, custody obligations, and investor qualification restrictions must still be maintained.
Market Context Highlights Institutional Bitcoin Product Appeal
