Sui said users can adopt quantum-safe keys without creating a new recovery phrase or changing wallet addresses.

Walrus Protocol and Astros AG have launched the Walrus Verifiable Trading Standard (WVTS) on the Sui blockchain to make trading data machine-readable and independently verifiable. The open standard, released on August 6, 2026, aims to address fragmentation and trust issues in crypto trading records, with a full specification and toolkit available under the Apache 2.0 license. Astros has tested the standard since April 2026 via its Scan platform, publishing over 22 million trade records with zero added latency. The initiative is driven by Astros CEO Jerry Liu and Mysten Labs co-founder Kostas Chalkias, and is designed to support AI agents that need verifiable data for autonomous trading decisions.

Sui's native stablecoin, USDsui, is introducing a novel model where yield from its reserve assets, including US Treasury bonds, is funneled back into the Sui ecosystem through open-market buybacks of SUI tokens and DeFi incentives. This contrasts with traditional stablecoin issuers like Circle or Tether, which retain all reserve yield without benefiting the underlying blockchain. Mysten Labs co-founder Adeniyi Abiodun highlighted the strategy as a way to close the value-extraction gap, redirecting economic value toward SUI holders and DeFi participants. Sui had already processed over $1 trillion in cumulative stablecoin transfers before USDsui's launch, with January 2026 alone seeing $111 billion in stablecoin volume. The market's initial response was cautious optimism, with SUI's token price rising 3.86% on launch day. The buyback mechanism offers flexibility: purchased SUI tokens can be removed from circulating supply or redeployed into DeFi liquidity pools. Bridge's involvement, and by extension Stripe's, adds institutional credibility. For investors, the key metric to monitor is USDsui's circulating supply over time, as the buyback's impact scales with the stablecoin's reserves. A $100 million reserve generating 4-5% yield yields $4-5 million annually for buybacks, while a $10 billion reserve could produce $400-500 million annually, representing a significant shift in stablecoin dynamics.

This week, the crypto market will see over $636.4 million in token unlocks from projects including Sui (SUI), EigenCloud (EIGEN), and Kamino (KMNO), which could introduce volatility. Sui will unlock 13.72 million SUI on August 1, worth $9.91 million, with tokens distributed among early contributors, community reserve, and Mysten Labs Treasury. EigenCloud unlocks 36.82 million EIGEN on August 1, valued at $7.63 million, allocated to investors and early contributors. Kamino unlocks 229.17 million KMNO on July 30, worth $4.14 million, primarily for stakeholders, advisors, and core contributors.

StarkWare and Sui launched privacy features this week allowing users to conceal transaction data while maintaining auditability and regulatory oversight. StarkWare's STRK20 framework for ERC-20 tokens on Starknet enables shielded balances and viewing-key-based disclosure under lawful request. Sui introduced a public beta for confidential transfers, hiding transaction amounts but allowing authorized access for compliance. The launches signal a shift toward institutional-friendly privacy models. Recent events, including a court-ordered freeze of funds in Zama's USDC wrapper and a bug disclosure by Zcash, have pushed privacy projects to accelerate compliance roadmaps and address reliability concerns.

Sui (SUI) launched confidential transfers in public beta on Devnet, hiding token balances and transfer amounts while keeping sender, receiver, and auditor access visible. The feature uses Twisted ElGamal cryptography and zero-knowledge proofs to validate transfers without revealing amounts. Unlike Monero, which hides all transaction details, Sui's design preserves compliance controls such as freeze and seize powers, with optional auditor keys. This targets institutions like payment firms and stablecoin issuers that need privacy without full anonymity. Partners including TRM Labs and Merkle Science are testing the system for risk scoring and monitoring. The move comes after Sui experienced three mainnet outages in late May. SUI token price rose nearly 5% following the announcement, trading at $0.76.

Sui co-founder Adeniyi Abiodun announced on June 5 that confidential transfers will be added to the Sui network, using range proofs to hide transaction amounts while protocol-level checks enforce supply integrity. This design aims to prevent exploits like the Zcash counterfeiting bug. The move is part of a broader push into privacy and agent payment infrastructure, including free tier payments and native payment intents for AI agents. Abiodun emphasized the team's focus on building through the bear market, following recent network outages and price declines.

Sui network developers attributed last week's three separate outages, totaling over 15 hours of downtime, to crash bugs in gas charging logic and a validator synchronization issue. The first two outages on May 28-29 resulted from a conflict between gas calculations and a new address balances feature in release 1.72, while a third was caused by a latent bug affecting randomness preservation during an epoch change. The Sui Foundation acknowledged accepting heightened risk with an interim fix to restore operations quickly. User funds were not at risk and no committed transactions were reverted. The price of SUI dropped 18% over the past seven days to $0.86, amid a broader market dip. These incidents mark Sui's third major reliability failure since its 2023 mainnet launch, following a two-hour transaction scheduling bug in November 2024 and a six-hour consensus divergence in January 2026.

Sui Mainnet has resumed normal operations after three outages on May 28-29, 2026, all caused by bugs in the 1.72 software upgrade. The first outage, lasting from 7am to 1:30pm PT, stemmed from a fee charging error when two transactions attempted to spend from the same address balance simultaneously, causing a negative balance. Validators deployed an interim fix, but a second outage occurred at 5am PT on May 29 due to an edge case where an error code bypassed the guard. A more complete fix was deployed by 8:30am. A third outage from 1:30pm to 7:20pm PT occurred at an epoch change when validators restarted to adopt the fix, but a latent bug prevented the network from recording a failed setup process, causing end-of-epoch logic to stall. No user funds were lost, and no confirmed transactions were reverted. SUI token traded around $0.88, down 2.57% in 24 hours. The Sui Core Team outlined investments to improve resilience, gas charging logic, and failure containment.

The Sui Foundation implemented a major upgrade to fix bugs that caused three outages on the Sui Network, resulting in over 15 hours of downtime across two days. The outages occurred Thursday and Friday, with the longest lasting over eight hours. All systems are now operational as of Monday. The foundation said the outages stemmed from crash bugs introduced in the 1.72 software release, affecting gas charging and causing negative balances. An interim fix for the initial bug triggered a third outage. No user funds were at risk and no committed transactions were reverted. The Sui (SUI) token has declined approximately 11% since the outages, trading at around $0.88 as of Monday, down from $0.99 before the first outage. Sui is the 13th-largest blockchain by total value locked at $519 million.
