Coinbase has launched native SUI staking for eligible customers, enabling users to earn daily rewards directly through their exchange accounts. The rollout coincides with Sui advancing its Bitcoin-focused Hashi testnet, which provides developers and institutions a controlled environment for building and testing Bitcoin-based financial applications.

SUI Staking Opens With Daily Rewards

Coinbase announced that customers can begin staking with a minimum of one SUI token. Estimated annual rewards range from 1.4% to 3.3%, depending on network conditions. The exchange distributes rewards following each 24-hour Sui network epoch and automatically adds earned rewards to each customer's staked balance.

This auto-compounding mechanism increases the token amount participating in future staking periods. However, actual returns may fluctuate as network activity and validator performance change over time. In proof-of-stake networks such as Sui, staking also serves a network function by delegating tokens to validators that participate in securing and operating the blockchain.

The exchange announced the service through an official post on X. "You can now stake SUI – directly on Coinbase," the company stated. It also promised "instant rewards, accumulated straight to your account."

Regional Restrictions and SEC Settlement

Coinbase noted that the staking service remains unavailable in certain jurisdictions. Regional regulations and individual account eligibility will determine which customers can access the product. The company also clarified that its announcement should not be interpreted as investment advice.

Exchange-based staking can simplify participation for users who prefer to manage assets through a custodial platform rather than operate wallets or delegate directly on-chain. Access to these services has remained sensitive to local regulatory requirements, making jurisdictional availability an important part of new staking rollouts.

The staking launch arrived as Coinbase resolved a long-running information dispute with the United States Securities and Exchange Commission. The SEC agreed to pay $150,000 as part of a settlement announced Wednesday. The legal matter centered on a Freedom of Information Act lawsuit involving requested agency records.

Despite these developments, Coinbase shares declined during Wednesday's trading session. COIN stock fell 3.67%, trading near $169.40 during intraday activity, continuing a recent downtrend in the exchange operator's market value.

Hashi Testnet Targets Bitcoin-Based Finance

Sui launched the Hashi testnet with support from more than 25 ecosystem partners. Developers, custodians, and financial institutions can now test Bitcoin applications ahead of a planned mainnet launch. The platform integrates Sui's blockchain performance with Hashi's Guardian Layer security system.

The Guardian Layer strengthens controls around Bitcoin used as collateral and supports transparent, programmable financial activity conducted through on-chain applications. Participants can evaluate security features and operational processes before deploying products on the main network. Testnets are commonly used to identify technical and operational issues before real assets and production users are involved.

Hashi targets applications including lending, credit products, and structured yield strategies. The effort reflects a broader push to bring Bitcoin liquidity into programmable finance while retaining additional controls around custody, collateral, and settlement workflows. Together, the Coinbase staking launch and the Hashi testnet expansion represent significant new infrastructure developments for both retail staking and institutional Bitcoin finance within the Sui ecosystem.
