Sui's Confidence Interval: From Wall Street's Newcomers to Ecosystem Challenges

Entering 2026, Sui has sparked market attention with a strong rally, but behind this enthusiasm lies a deeper issue—can a public chain evolve from a technical experiment into an institutional asset and maintain market trust? The world’s largest crypto asset management firms, Grayscale and Bitwise, have successively submitted applications for Sui spot ETFs to the SEC, signifying that SUI tokens are officially entering the same institutional evaluation basket as BTC and ETH. However, behind this shiny narrative, the Sui ecosystem faces a severe test regarding credit and resilience.

Impressive On-Chain Performance, but Trust Is Just Beginning

The development trajectory of the Sui ecosystem over the past two and a half years has been impressive. Since the mainnet launched in May 2023, its total value locked (TVL) experienced exponential growth, reaching a peak of $2.6 billion in October 2025. Although market adjustments caused a pullback, this data still reflects substantial user and capital recognition of the Sui network.

In terms of transaction throughput, Sui has achieved performance metrics difficult for traditional public chains. Peak daily transaction throughput reached 66.2 million, with the average daily throughput remaining above 4 million over the past year, validating its horizontal scalability to meet large-scale user demand. Public chain fees also grew from an early $2 million to about $23 million, an 11.5x increase, indicating ongoing network activity growth.

User growth is a more direct signal. Daily active users (DAU) on Sui rose from initial tens of thousands to a peak exceeding 2.5 million. Although recent declines occurred, the average DAU remains around 600,000, maintaining healthy levels. Notably, the retention rate of old users remains stable above 20%, reflecting high user stickiness and ecosystem appeal.

However, whether these large data indicators can translate into sustainable trust remains an open question. Data growth demonstrates technical potential, but trust is built on recognition of the ecosystem’s long-term health—a more complex dimension.

Countdown to Institutional Entry: Will ETFs Be a Turning Point?

On December 5, 2025, Grayscale filed an S-1 registration statement with the SEC for a Sui spot ETF, planning to list on NYSE Arca. The document discloses that the Grayscale Sui Trust (SUI) ETF will directly hold SUI tokens and incorporate staking mechanisms, meaning investors can gain price exposure and earn additional rewards through blockchain validators.

Shortly after, on December 19, 2025, Bitwise submitted its own Sui spot ETF application, choosing to list on Nasdaq, with Coinbase as custodian. This move marks SUI’s formal entry into the institutional asset basket alongside Bitcoin, Ethereum, Solana, and others.

For Sui, the arrival of ETFs is significant—it greatly lowers the entry barrier for traditional wealth management institutions. Through ETF products, large asset managers can participate in Sui’s appreciation potential without directly managing crypto custody. Simultaneously, ETFs will significantly enhance SUI’s liquidity depth, reshaping its valuation logic.

Currently, the circulating market cap of SUI is about $5.81 billion, with a fully diluted valuation (FDV) around $15.31 billion. Although the market has smoothly absorbed over $60 million worth of token unlocks in early 2026 without panic selling as expected, this does not mean trust is fully established. The entry of institutional capital will be a key trust signal but also demands higher resilience from the Sui ecosystem.

Privacy-Enabled Business, but Compliance Comes with New Concerns

On another track of institutional recognition, Sui is advancing its privacy features. On December 30, 2025, Mysten Labs co-founder and Chief Product Officer Adeniyi Abiodun announced that Sui will launch native private transaction capabilities in 2026.

Unlike other privacy solutions on the market, Sui’s privacy design incorporates deep business logic. While transparency in traditional public chains ensures fairness, it severely hampers enterprises needing to protect trade secrets and privacy-sensitive users. Sui’s privacy approach aims to provide end-to-end confidentiality via zero-knowledge proofs while maintaining high throughput.

Importantly, Sui introduces a “compliance-friendly design,” which is innovative but also involves compromises. The system includes audit hooks that allow transaction details to be opened to regulators under certain compliance processes; supports KYC/AML integration so financial institutions can perform anti-money laundering checks while preserving privacy; and plans to incorporate post-quantum cryptography standards like CRYSTALS-Dilithium and FALCON to ensure data remains unbreakable for decades.

This “regulated privacy financial network” positioning aims to attract highly sensitive data institutions like banks and commercial entities, but may raise doubts among crypto purists. A more severe technical challenge is how to maintain high TPS while integrating zero-knowledge proofs and quantum-resistant algorithms—posing a real test for Sui’s engineering team.

Liquidity Upgrades and Prosperity: Who Is Lurking Beneath the Surface?

The Sui ecosystem is active in liquidity-related developments. As a long-standing leader in TVL rankings, NAVI Protocol launched Premium Exchange (PRE DEX) on December 29, 2025, marking its evolution from a single lending protocol to a comprehensive DeFi infrastructure.

PRE DEX’s innovation lies in its premium discovery mechanism—many protocol tokens exhibit price dislocation at different market stages, and PRE DEX provides a market-driven pricing platform. For institutional investors, this greatly improves asset management efficiency, allowing users to allocate multi-chain and multi-protocol assets via a unified interface, reducing cross-protocol operation costs.

Additionally, several projects focused on liquidity optimization have emerged within the ecosystem. Magma Finance completed a $6 million strategic funding round in December 2025 (led by HashKey Capital), introducing an adaptive liquidity market maker (ALMM) model. Its core innovation is AI-based real-time analysis of market volatility, automatically adjusting asset price distributions to rebalance capital into active trading zones. The system also monitors Mempool to prevent MEV attacks.

Ferra Protocol raised $2 million in a pre-seed round in October 2025 (led by Comma3 Ventures) and launched Sui’s first dynamic liquidity market maker (DLMM) DEX. Its vision is to make capital flow with market sentiment like “living water,” rather than static deposits.

These upgrades seem prosperous but also hint at a question: if liquidity and incentives are so easily adjustable and optimizable, what is the true foundation of trust?

DeFi Risk Alert: How Can a Credit Crisis Spread?

Risks within the Sui ecosystem are gradually surfacing. SuiLend, the largest on-chain lending protocol with nearly $750 million TVL accounting for 25% of the entire chain’s share, has underperformed. Its token SEND has fallen over 90% in the past year.

Despite claiming an annualized revenue of $7.65 million and promising that 100% of protocol fees are used for token buybacks, the actual buybacks have failed to provide the expected price support. Since 2025, only about $3.47 million (roughly 9% of circulating supply) has been repurchased, with minimal effect given its market cap of only $13 million. More seriously, community members question whether buyback strategies involve insider trading, turning into a way for the team to offload tokens.

In the IKA margin event, SuiLend did not activate an insurance fund but forcibly deducted 6% of user principal, further damaging community trust. Moreover, the protocol relies heavily on monthly subsidies from the Sui Foundation—several million dollars—to sustain operations, revealing the fragility of its revenue model.

This case sounds an alarm: token buyback strategies, amid high emissions and early VC dumping, are like a drop in the bucket. The deeper issue is that many projects’ incentive structures are fundamentally misaligned—when tokens flow to VCs rather than users, promises to users become castles in the air.

When evaluating ecosystems, market participants should look beyond surface metrics like TVL and revenue, and instead scrutinize governance mechanisms, incentive structures, and community trust. An ecosystem lacking a solid credit foundation cannot support long-term institutional capital, regardless of how advanced the technology or how bright the data.

The Long Road to Trust

Sui’s path to Wall Street is indeed attractive, but more importantly, its ecosystem’s foundation must be solid and reliable. Technical indicators’ explosive growth proves potential, but trust is the true core of survival.

Transitioning from a technical experiment to a mature economy is not an overnight process. Sui needs to balance innovation and reasonable valuation while filling the trust gap as a core component of value growth. This entails more transparent governance, more rational incentive design, and stronger ecosystem oversight.

As institutional capital begins to flow in, every step Sui takes will be scrutinized. The trust zone is not static—it will be continuously adjusted by every project risk, governance decision, and user experience within the ecosystem. Only through long-term validation and building a solid credit record can Sui truly transform from a “Silicon Valley darling” into a “Wall Street newcomer.”
