Sui Network Recent Updates: What’s New and Why It Matters

Sui Network has seen rapid development across institutional adoption, stablecoin infrastructure, decentralized finance, and core protocol upgrades. 

Recent updates show Sui expanding its market footprint, improving underlying technology, and attracting regulated financial products. These developments cover on-chain yield products, new stablecoins, improved consensus design, and increased institutional participation.

YLDS Comes to Sui: What Does This Mean?

Figure Technology Solutions has launched YLDS, a regulated, yield-bearing security token, on Sui. This is the first time YLDS has expanded beyond the Provenance blockchain.

YLDS is registered with the U.S. Securities and Exchange Commission. It is backed by short-term Treasurys and repurchase agreements. The token pays yields daily and distributes them monthly. The payout structure matches the Secured Overnight Financing Rate (SOFR) minus 35 basis points.

According to Figure, YLDS will support DeepBook, Sui’s leading limit order book. Stablecoins on DeepBook will automatically convert into YLDS, creating a base layer of yield for the venue. This design also supports the platform’s upcoming margin trading.

Why this matters

• It brings regulated yield instruments to a public Layer 1.
• It supports real trading activity rather than experimental liquidity loops.
• It removes traditional intermediaries by automating yield distribution on-chain.

This move shows how institutional debt instruments can function directly within a high-performance network.

Grayscale Lists Sui Trust on OTCQX

Grayscale has expanded its Sui offering by launching Grayscale Sui Trust (GSUI) for public trading on OTCQX. This provides U.S. investors regulated exposure to Sui without interacting directly with the blockchain.

The Trust has been available privately to accredited investors since August 2024, and its quotation now aligns with Grayscale’s strategy to move private products into public markets.

Key points for context

• Grayscale is the largest digital-asset investment platform.
• GSUI increases institutional access to Sui.
• It reflects growing interest in Layer 1 networks focused on transaction speed and developer usability.

Institutional listing of native assets is an important signal of maturing demand.

SUI Group Partners With Bluefin

SUI Group Holdings has announced a strategic lending partnership with Bluefin, the largest decentralized exchange on Sui. Under the agreement, SUI Group will lend 2 million SUI to Bluefin and receive a 5% revenue share paid in SUI.

The goal is to encourage institutional liquidity and support on-chain markets.

This partnership aims to

• Connect traditional financial participants with Sui’s on-chain markets.
• Deepen liquidity for trading and lending.
• Create new recurring value streams for ecosystem growth.

USDsui Unveiled and Why Is It Important?

On November 12, Sui announced USDsui, a native stablecoin built using Bridge’s Open Issuance platform. It is designed to become a core stablecoin across Sui’s economy.

USDsui will work across Sui wallets, DeFi protocols, and applications at launch. It will also be interoperable with other Bridge-issued stablecoins on platforms such as Phantom, Hyperliquid, and MetaMask.

Features of USDsui

• Developer-ready stablecoin built on enterprise-grade infrastructure.
• Compliance-aligned, designed to meet GENIUS Act requirements when active.
• Supports real-world use cases, such as remittances and cross-border payments.
• Integrated with Sui’s architecture, ensuring fast settlement and high throughput.

Revenue earned by Sui from USDsui operations will be reinvested into ecosystem programs.

Why this launch matters for Sui

Sui processed $412 billion in stablecoin transfer volume between August and September 2025. A native stablecoin built specifically for Sui provides more predictable liquidity and supports high-frequency transactions across gaming, DeFi, and payment apps.

R25 Brings Real-World Assets to Sui

The R25 protocol has introduced rcUSD and rcUSDp on Sui, expanding real-world asset (RWA) access for users.

rcUSD is supported by regulated, interest-generating financial instruments. It is designed to maintain a value of 1 USD. rcUSDp is its yield-bearing counterpart and represents staked rcUSD.

Why rcUSD and rcUSDp matter

• They bring tokenized money-market exposure to Sui.
• Users can access institutional-grade RWA yield opportunities.
• The tokens are built for compliance-aware environments, helping bridge traditional markets and blockchain systems.

RWA growth is a major trend across global finance, and Sui is positioning itself early.

Institutional Access Expands With Crypto.com

Crypto.com has partnered with the Sui Foundation to roll out custody and liquidity support for SUI tokens. The service includes cold storage, compliance monitoring, audit trails, and access to deep liquidity.

This targets institutional clients that need secure environments for large token holdings.

Benefits include

• Risk-mitigated custody.
• Instant settlement.
• Transparent reporting.
• Support for regulatory requirements across jurisdictions.

Mysticeti v2: How Sui’s Consensus Just Got Faster

Mysticeti, Sui’s consensus protocol, is built on Directed Acyclic Graphs (DAGs). It launched on mainnet in 2024 and offered low-latency and scalable performance.

Mysticeti v2 introduces improvements that remove unnecessary compute steps and make consensus more efficient.

Changes in Mysticeti v2

• Integrates transaction validation directly into consensus, eliminating redundant steps.
• Introduces Transaction Driver, making transaction submission and confirmation more streamlined.
• Reduces latency and compute load for both fastpath and non-fastpath transactions.

Background

• Older systems like Tendermint use sequential block proposing.
• DAG-based systems improve parallelism and censorship resistance.
• Mysticeti removes certification steps to increase performance further.

By refining its approach, Sui unlocks more of the potential built into its architecture.

Sui’s Q3 Performance: What Do the Numbers Show?

Messari’s Q3 Sui Network report highlights strong market and infrastructure growth.

Key metrics

• $456 million average daily DEX volume (up 24% QoQ).
• $11.63 billion circulating market cap (up 23.3%).
• $2.11 billion DeFi TVL (up 19.9%).
• 75.4% of eligible supply staked.
• 122 active validators.

Some metrics declined, such as total network fees (down 11.1%) and daily active addresses (down 9.5%), which is typical after periods of high activity.

Infrastructure expanded with

• passkey support,
• Seal launch,
• Ika Network for MPC-based coordination,
• integrations with LayerZero, Dune, NEAR Intents, Dfns, and others.

These updates show both growth and ongoing optimization.

Sui Builder Program in the Philippines

A new Sui Builder Program in Palawan trained young developers to write Move smart contracts. Students built on-chain applications such as Campfire, a certificate and event-badge system.

The initiative was supported by regional government offices and demonstrates how Sui is used for education, not only for finance.

Conclusion

The recent updates to Sui show a network strengthening its core technology, expanding institutional access, and supporting regulated financial instruments. With developments across consensus design, stablecoins, RWAs, and DeFi infrastructure, Sui continues to build a high-performance environment designed for real usage and sustained ecosystem activity.
