Coinbase Rolls Out SUI Staking as Hashi Testnet Marches Toward Bitcoin Bridge 🪙

Coinbase has begun offering staking services for Sui ($SUI), enabling eligible customers to earn rewards directly through the exchange. The rollout coincides with the launch of the Sui Hashi testnet, a platform designed for developers and institutional partners focused on Bitcoin infrastructure to test key features prior to a mainnet deployment.

In a post on X on Wednesday, July 22, Coinbase said, "You can now stake SUI – directly on Coinbase." The exchange added that users can receive "Instant rewards, accumulated straight to your account" and framed the service with the line, "less time spent searching, and more time spent earning." Coinbase set a minimum staking amount of 1 SUI and estimated annual rewards in the range of 1.4% to 3.3%, paid out daily at the end of each 24-hour network epoch. Rewards are automatically compounded back into users' staked balances. The exchange also cautioned that "Staking is not available in all regions" and stated that the information provided is not intended as investment advice or a buy/sell recommendation.

Hashi is positioned as a testing ground for Bitcoin-related infrastructure on Sui, giving developers a venue to validate core functions before any mainnet rollout. The dual announcements extend a series of recent Sui milestones and broaden the network's footprint by combining a new institutional-facing Bitcoin test environment with a retail-accessible staking product offered through one of the largest U.S.-based exchanges.
