Coinbase announced on July 22 that eligible customers can now stake SUI directly on the exchange, with estimated annual rewards ranging from 1.4% to 3.3%. SUI is the native token of Sui, a Layer-1 blockchain developed by Mysten Labs using the Move programming language. The rollout coincides with SUI testing a key resistance level near $0.78 and the launch of Sui's Hashi testnet, which has attracted more than 25 ecosystem partners for Bitcoin-backed financial application testing.

Coinbase SUI Staking Details

Users can begin staking with a minimum of 1 SUI. Rather than following a weekly or monthly payment schedule, Coinbase will distribute rewards after each 24-hour network epoch. Rewards are automatically added to the customer's staked balance through compounding, allowing subsequent payouts to accrue on the updated amount.

"You can now stake SUI — directly on Coinbase," the exchange wrote in its announcement.

Estimated returns fall between 1.4% and 3.3% annually, though Coinbase noted that the quoted rate may fluctuate based on network conditions. The company described the return range as an estimate rather than a guaranteed yield and stated that the announcement does not constitute investment advice or a recommendation to buy or sell SUI.

Regional restrictions apply. Coinbase confirmed that staking is unavailable in certain jurisdictions, with access dependent on the customer's location.

Staking has been a growth area for major exchanges, though it has also drawn regulatory scrutiny. In June 2023, the SEC charged Coinbase with operating its staking program as an unregistered securities offering — part of a broader enforcement action the exchange is contesting. Against that backdrop, each new staking listing represents continued product expansion amid ongoing litigation.

SUI Price Action and Technical Structure

When TradingView charts were captured on July 22, SUI traded near $0.772 on Binance, placing the token just below a resistance area that has rejected multiple advances since June.

On the 4-hour chart, SUI has formed a series of higher lows against horizontal resistance near $0.7806, creating a structure resembling an ascending triangle. The rising trendline extends from the late-June low near $0.65 toward the current price. A 4-hour close above $0.7806 would confirm a breakout, contingent on accompanying buying activity. The pattern's measured move points toward approximately $0.9095, representing a potential increase of about 16.7% from the breakout line.

Momentum readings present mixed but generally constructive signals. The 4-hour relative strength index (RSI) stood at 59.97, below its signal average of 61.75 and well short of the overbought threshold at 70, suggesting SUI retains room to advance. However, the slight RSI slowdown indicates buyers have not yet secured the breakout.

The Aroon indicator offered a more cautious reading, with Aroon Down at 42.86% and Aroon Up at 7.14%. The higher downside reading suggests recent upward momentum has weakened, even as price continues to hold its rising support line.

Daily indicators present a firmer accumulation picture. The MACD line sat at 0.0063, above the signal line at 0.0040, while the positive histogram was beginning to expand. Chaikin Money Flow stood at 0.10, indicating that buying pressure exceeded selling pressure during the measured period.

SUI must first clear $0.8188 — the 78.6% Fibonacci retracement of its decline from $1.4246 to $0.6539 — before the daily chart can support a larger recovery. Above that barrier, Fibonacci levels place the next resistance zones at $0.9483 and $1.0392. Failure to break the $0.78–$0.82 area would keep SUI within its current consolidation range.

Based on the charts, the rising 4-hour trendline provides initial dynamic support near $0.74, while the daily swing low at $0.6539 remains the primary downside level.

Sui Hashi Testnet and Bitcoin-Backed Applications

Arriving alongside the Coinbase staking rollout, Sui's Hashi testnet provides developers, institutions, custodians, and infrastructure providers with an environment to test Bitcoin-backed financial applications ahead of a mainnet release. The Sui Foundation stated that more than 25 ecosystem partners have joined the testing phase. The initiative fits within a broader industry trend of building decentralized financial products on top of Bitcoin, the largest cryptocurrency by market capitalization, as projects across multiple chains seek to put idle BTC holdings to productive use.

On June 23, 2026, the Sui Foundation's official X account posted:

Hashi is a native Sui primitive turning ~$1T of idle $BTC into productive financial collateral. Ahead of its global testnet launch this July, @CumberlandSays, @swissborg, and @0xfluid are the latest to join 20+ partners in the Hashi ecosystem.

— Sui (@SuiNetwork) June 23, 2026

Hashi combines Sui's network with a security system known as the Guardian Layer, according to the foundation. The protocol is designed to give participants additional control over Bitcoin used as collateral while keeping transactions transparent and programmable onchain. Through the testnet, participating firms can experiment with BTC-backed lending, credit products, and yield strategies without deploying those services on the final network.

The Sui Foundation identified Wave Digital Assets as a launch partner involved in the institutional testing effort. Cumberland, Swissborg, and Fluid were named as the latest partners to join the ecosystem.

SEC Settlement and Coinbase Stock Performance

Coinbase's staking release arrived on the same day the exchange and the U.S. Securities and Exchange Commission ended a long-running Freedom of Information Act dispute. As reported by crypto.news, the SEC agreed to pay Coinbase $150,000 as part of the settlement. The FOIA case was separate from the SEC's broader enforcement action against Coinbase, which remains ongoing.

Coinbase shares did not follow the positive product news during the session. According to Yahoo Finance data, COIN fell 3.65% to $169.42 intraday, diverging from SUI's attempt to break its short-term resistance.
