Key takeaways

• Sui’s object-based architecture allows parallel transaction execution, unlike traditional EVM chains.
• Despite technical advantages, Sui’s DeFi growth lags behind chains like Solana and Base.
• As of early July 2025, Sui’s TVL stands at $1.82 billion with increasing stablecoin volumes, but without a flagship DeFi app.
• Adoption is split across smaller protocols like Scallop and NAVI, which haven’t yet unified the ecosystem.
• The question remains: Can Sui’s storage-native design translate into long-term DeFi dominance?

Sui didn’t launch as another Ethereum clone. Instead, from its May 2023 debut, it positioned itself around a different core proposition: treating storage as a first-class primitive. Its object model, paired with the Move VM, enables parallel execution of transactions that don’t touch the same state making execution faster and more efficient.

This shift also changes how dApps function. Assets become discrete “objects” tokens, NFT items, staking positions with ownership and updates happening at the object level. That enables more dynamic on-chain asset behavior, shorn of external indexing or heavy smart contract overhead.

But does this technical edge translate into DeFi momentum? Not yet. Data from DeFiLlama shows Sui’s Total Value Locked (TVL) at approximately $1.82 billion as of July 4, 2025 just shy of the $2 billion milestone. While that ranks Sui among the top 10 chains, it remains well behind Solana’s $5.6 billion and Base’s $1.8 billion using the same source framework.

Even more revealing: Sui’s on-chain stablecoin volume surpassed $1 billion in June, but its protocol usage remains fragmented, split across emerging lenders and niche apps, not anchored by a flagship DeFi hub.

In short, Sui has the technical scaffolding but DeFi as a use case hasn’t fully materialized. The rest of this article will explore why, and whether that gap is beginning to close.

Ecosystem Plays: From Narrative to Real Usage

Scallop leads Sui’s DeFi scene with $130 M TVL (2025 Q2), solidifying its role in lending and staking architecture.

• NAVI holds around $519 M TVL, powering asset-specific vaults (SUI, USDC, wETH) that self-track capital usage via Sui’s object model no external oracles required.
• Cetus DEX recovered from a $223 M exploit in May, bouncing back with $124 M TVL by June and daily volumes surpassing $120 M.
• While each protocol performs well solo, liquidity remains siloed, with no unified DeFi hub connecting lending and trading primitives.
• The Sui Foundation funded $4.7 M across 86 projects by June, but no July liquidity incentive programs have launched unlike competing chains actively refreshing rewards.
• The key challenge now: translate Sui’s object-based modularity into interconnected capital flows across its top protocols that will determine whether the chain becomes a cohesive DeFi ecosystem or remains a collection of standalone functions.

Bridging the Liquidity Gap: Is It Architecture or Incentives?

For a Layer‑1 with infrastructure advantages, Sui still struggles with one thing: sticky, multi‑protocol liquidity. The fragmented usage across Scallop, NAVI, and Cetus raises a deeper issue: is this a technical limitation, or an economic one?

At first glance, Sui’s object-based model enables efficient throughput and modular asset handling but real liquidity isn’t guaranteed. On chains like Ethereum or Base, protocols interconnect closely; on Sui, capital remains dispersed.

Economic factors raise red flags. According to DeFiLlama, NAVI’s deposits are nearing $527 million TVL but over 65% appear idle, indicating low reuse and limited capital flow across Sui dApps.

Meanwhile, Scallop continues to hold around $539 million TVL, nearly neck-and-neck with NAVI, yet both lack shared liquidity infrastructure .

The Sui Foundation disbursed ecosystem grants totaling $4.7 million across 86 projects as of June 2025 supporting DeFi, gaming, and tooling. But there’s no sign of a new, large-scale DeFi liquidity incentive in June/July 2025. By contrast, Base has just launched fresh on-chain rewards coinciding with its surge to nearly $4 billion TVL in early July 2025.

Some developers argue Sui needs new DeFi frameworks tailored to its architecture. But capital follows incentives not innovation. Without updated reward programs or cross-app yield structures, Sui risks plateauing despite tech promise.

Market Perception: Games, DeFi, or Both?

While Sui is often framed as a next-gen infrastructure layer, much of its real-world traction in mid-2025 is coming from gaming and high-frequency user apps, not purely financial primitives.

According to NFT Evening’s June 27 report, Sui’s TVL  reached $1.82 billion by early July 2025, with stablecoin volume exceeding $1.2 billion  but a significant portion of on-chain activity came from gaming transactions tied to interactive asset use.

On-chain metrics show Sui handling 20–30 million daily transactions through June, with gaming and social dApps accounting for a large share. In user engagement terms, AI Invest reported on July 3 that Sui saw daily new wallet creation surge past 600,000, a momentum signal driven mainly by onboarding into gaming and social finance apps.

Furthermore, BlockchainGamer.biz announced on June 26 that Lineup Games selected Sui as its default network for titles like Striker League, highlighting Sui’s growing appeal to mainstream game developers. Taken together, these data points paint a picture of Sui as a gaming-heavy layer‑1, with robust wallet growth and transaction volume but comparatively fewer DeFi-native use cases dominating that activity.

What Builders and Traders Should Actually Watch

• Fresh incentives: Sui has yet to announce a fresh DeFi liquidity or yield incentives round in Q3–Q4 2025. This contrasts with chains like Base, which launched a new TVL reward program in early July 2025.
• Infrastructure upgrades: Sui Foundation’s June 2025 Developer Digest highlights work on DeepBook, its core infrastructure module aimed at improving cross-app order book access and composability. This is one to track for improving liquidity flow between protocols.
• Wallet engagement vs TVL: While protocol-level TVL shows stagnation, daily new wallet creations spiked to over 600,000 in early July, driven by gaming and social apps rather than DeFi yield seekers. According to AI Invest (July 3, 2025), this split between high engagement, low capital reuse is a key signal of Sui’s mixed ecosystem dynamics.

Cross‑Chain Composability: Sui’s Edge Outside EVM

One of Sui’s most compelling differentiators might be its object‑native support for native asset routing, not just token bridging. Reportedly, Wormhole’s NTT (Native Token Transfer) framework was launched on Sui, allowing Momentum Finance to serve as the first DEX supporting NTT-powered EVM and Solana assets all while planning full bridge support by September 2025.

This goes beyond cross-chain swaps: it enables stateful, non-fungible asset structures from other networks to enter Sui’s ecosystem. That means we could soon see wrapped vaults or NFT-backed positions flowing onto Sui seamlessly, something standard EVM chains can’t handle today.

If Sui maintains this composability and dApps build around these cross-chain primitives it could emerge as the primary settlement layer for hybrid asset flows, especially in GameFi and dynamic DeFi not possible on legacy chains.
