The people shaping Sui’s Move-based DeFi ecosystem
Sui reached $810.5 million in Total Value Locked following the integration of USDC and significant liquidity surges. Key protocols like NAVI Protocol and Scallop Lend drive ecosystem activity through lending and decentralized governance.
The TVL and Liquidity Surge
Sui hit $810.5 million in Total Value Locked on September 19, according to DeFiLlama data. This surge follows the integration of USDC into the network, which pushed SUI prices toward $1.18. I see a network that moves capital rather than just talking about it. The market cap for SUI reached $5.188 billion as of September 28, while 24-hour trading volume hit $1.207 billion. This volume is three times higher than Sei’s reported 24-hour volume of $400 million. Banxa added the SUI token to its platform to increase access via global payment methods, and Mysten Labs’ Sui Wallet allows users to purchase SUI through Banxa’s fiat on-ramp. Oracle Stork partnered with Sui to provide faster pricing data to developers and DEXs. The SUI 7-day price range was between $0.8817 and $1.29.
| Metric | Value (as of late Sept 2026) |
|---|---|
| SUI Market Cap | $5.188 billion |
| SUI 24h Volume | $1.207 billion |
| Network TVL | $810.5 million |
| SUI Circulating Supply | 4.097 billion |
The growing demand for liquidity creates a cycle of activity that keeps the network busy. This momentum attracts new developers to the ecosystem.
Protocol Performance and Governance
Lending protocols dominate the TVL distribution. NAVI Protocol holds $310 million in locked assets, and Scallop Lend maintains $140.5 million. Suilend also holds $134 million. Four protocols on the network have more than $50 million in TVL, and nine protocols have more than $10 million. I find the concentration of capital in these few protocols a risk for diversification. Cetus produces $170.7 million in daily volume, while Bluefin generates $78.5 million. Other active DEXes include Aftermath Finance and FlowX Finance. You already know that liquidity drives these numbers, but the recent Cetus incident shows how quickly things can fail. Cetus faced a $60 million exploit that led to a $162 million asset freeze. Cetus reached a feat by surpassing $1 billion in total transaction volume. NAVI voted to support a full fund recovery for users through a community-approved protocol upgrade. This vote included both Sui validators and token holders using stake delegation.
The community relies on these validator choices to ensure that stolen or frozen assets move into a secure multisig trust until they reach the rightful owners via a community-approved protocol upgrade.
The governance process remains a central part of the ecosystem. Validators like NAVI use their influence to shape security frameworks. Token holders participate by delegating their stake to these validators. This structure aims to provide oversight for decentralized protocols. Transparency dashboards display these validator choices to the public. The community vote launched by the Sui Foundation seeks to return funds to affected users through a protocol upgrade. NAVI continues to collaborate with the Sui Foundation and law enforcement to ensure a just recovery process.
The Technical Foundation and Developer Momentum
The technical stack relies on the Move programming language and an object-centric data model. This model treats assets as individual objects with unique identifiers. Because transactions involving independent objects do not conflict, the network processes them in parallel. Mysticeti, the consensus protocol, achieves finality in under 400 milliseconds under normal load. The engineering team from Mysten Labs, which includes former Meta employees, built this architecture to avoid the bottlenecks found in account-based blockchains. This design differs from the account-based model used by Ethereum where transactions must queue.
The Move language prevents common errors because it treats digital assets as resource types that a developer cannot copy or delete by mistake during a transaction.
The network currently has 106 validators operating 413 nodes. Adeniyi Abiodun, the Chief Product Officer at Mysten Labs, confirmed plans for native private transactions at the protocol level. These features aim to protect transaction details from everyone except senders and receivers. Sui also uses a storage fund mechanism where a portion of gas fees goes into a shared fund when an object is created.
Will the planned rollout of native private transactions in 2026 solve the privacy needs of large institutions?
If you are watching these developments, keep an eye on the Q1 2027 token unlock schedule. A significant portion of team and investor tokens will release then, which might create selling pressure. The SUI market cap to FDV ratio is 0.41; 59% of the total supply remains locked or unvested.
