Sui said Coinbase Institutional will expand custody and treasury management services to the Sui Foundation as the partnership deepens.
Sui Network and Coinbase announced a partnership under which Coinbase will adopt the Sui token standard across its platform, adding Sui to the exchange’s list of supported standards alongside Ethereum and Solana. The companies said the integration will simplify how Sui-based tokens are handled for trading, custody, and developer workflows on Coinbase services.
A token standard is often supported to take into account the creation, indexing, and transfer of assets through an exchange stack, which may impact deposits and withdrawals, custody operations, and application tooling compatibility.
In the latest news, CNF outlined that Sui positioned itself as the blockchain of autonomous AI agents, claiming that agents require shared, verifiable state and atomic workflows to prevent partially conflicting actions across services.
Additionally, Coinbase Institutional and Sui are extending their relationship through custody and treasury management services for the Sui Foundation. This positions Coinbase Custody for broader operational support tied to Sui-related assets, including storage and balance management, which are required by regulated funds and corporate treasury teams.
The partnership follows Coinbase’s move in December 2025 to allow SUI trading for New York residents. With New York access in place, the token-standard adoption adds an infrastructure layer that can support the issuance and movement of Sui-based tokens through Coinbase products used by both individuals and institutions.
Institutional interest has also been building through proposed investment vehicles tied to SUI. Bitwise filed a registration statement in December 2025 for a spot SUI exchange-traded product that names Coinbase Custody Trust Company as the custodian for the trust’s Sui holdings, according to the SEC filing.
The document describes Coinbase Custody’s role in safeguarding the assets held by the trust under a custody agreement. Elsewhere, Sui’s recent ecosystem updates revolved around new exchange access and DeFi tooling releases. They included support for SUI on HashKey Exchange and the launch of automated vault products on Sui by Full Sail.
