In 2025, what key upgrades have mainstream DeFi applications on TRON achieved?
JustLend DAO, SUN.io, and other mainstream DeFi applications on TRON have achieved multi-dimensional systematic upgrades in 2025.
Navigating Web3 tides with focused insightsAs the financial core engine of the TRON ecosystem, the DeFi sector achieved a leapfrog upgrade in 2025, evolving from a basic financial function provider to an ecological value hub through the continuous iteration and innovative expansion of mainstream applications like JustLend DAO, SUN.io, BTTC, and WINkLink. This has established a secure, efficient, decentralized financial service system that combines innovative vitality with collaborative capabilities.
The lending protocol JustLend DAO, as the core vehicle for asset appreciation within the TRON ecosystem, has not only become the primary gateway for traditional compliant capital to enter the TRON ecosystem but has also deeply bound token value to protocol revenue and ecological growth through the implementation of a large-scale JST buyback and burn mechanism, forming a stable value closed loop.
The core liquidity hub SUN.io achieved significant expansion in its business structure. On one hand, its Meme coin issuance platform SunPump continuously ignited ecological fervor, activating market liquidity and becoming the core engine for ecological traffic growth. On the other hand, the newly launched decentralized perpetual contract platform SunX successfully filled the gap in ecological derivative services, synergizing with the existing spot business to build a diversified service matrix of "spot trading + derivative hedging + innovative asset issuance," comprehensively enhancing the breadth and depth of liquidity services.
The cross-chain protocol BTTC made breakthrough progress in cross-chain transmission efficiency and security. In June, it completed a major upgrade to version 2.0, reconstructing the underlying logic through a modular layered architecture, achieving standardization and efficiency improvements in cross-chain processes. It also simultaneously optimized the BTT token economic model, reducing the total supply to enhance scarcity. This enhanced network security protection capabilities while injecting sustained momentum into the token's long-term value, making it the core value transmission infrastructure connecting TRON with multi-chain ecosystems.
The oracle infrastructure WINkLink continuously broadened the reach of its data services through technological upgrades and ecological resource integration, providing crucial and reliable foundational data support for the diversified application deployment and scaled development of the TRON ecosystem.
Leveraging the systematic breakthrough achievements of mainstream DeFi applications across multiple dimensions—value capture, business matrix construction, cross-chain interoperability, and foundational data support—the TRON DeFi ecosystem not only strengthened the synergistic effects and value circulation cycles among its internal components but also solidified its foundational capabilities as a next-generation decentralized financial hub, unleashing a continuous stream of innovative vitality.
DeFi Value Deepens Continuously: JST Large-Scale Buyback & Burn; SUN.io Adds Derivative SunX; BTTC Optimizes Token Model; WINkLink Expands Service Scenarios
JustLend DAO: From Lending Protocol to Ecological Value Hub
As a core pillar of the TRON ecosystem's financial infrastructure, JustLend DAO has achieved a leapfrog development from a lending protocol to an ecological value hub through continuous functional integration and strategic upgrades, building a full-chain decentralized financial solution integrating asset lending/appreciation, staking services, and Gas cost optimization.
Currently, JustLend DAO has completed deep integration of multiple core DeFi modules, forming an integrated product matrix covering functions such as the lending market (SBM), liquid staking sTRX (Staked TRX), and Energy Rental, providing users with comprehensive and diversified on-chain financial services. Users can fulfill all-scenario financial needs—including SBM lending, TRX network staking, and Energy Rental to reduce on-chain Gas costs—on the single JustLend DAO platform without cross-platform operations, thereby comprehensively enhancing capital efficiency and interaction experience.
Beyond core products, JustLend DAO, with a focus on user experience, innovatively launched the GasFree smart wallet in March of this year, supporting users to deduct transaction fees directly from transferred tokens, breaking the industry limitation of "needing to hold native tokens to transact." Additionally, JustLend DAO simultaneously launched a 90% transfer fee subsidy campaign, meaning users only need to pay approximately 1 USDT in fees for each GasFree USDT transfer (regardless of amount).
In mid-October, JustLend DAO officially implemented a large-scale JST buyback and burn mechanism, explicitly allocating all protocol net income and a portion of revenue exceeding $10 million from the USDD multi-chain ecosystem in full to the JST buyback and burn fund pool. Subsequently, JustLend DAO extracted approximately $59.087 million from existing revenue to initiate the first round of burning, executing the first phase at a 30% ratio (approx. $17.726 million), corresponding to the burning of 559.8 million JST tokens, accounting for 5.66% of the total token supply; the remaining 70% will be executed quarterly in installments.
This buyback and burn initiative fundamentally optimized the JST economic model: on one hand, by actively reducing the circulating supply, it enhances token scarcity through a deflationary effect, solidifying long-term value support; on the other hand, it achieves deep binding between ecological revenue and token holder interests.
Regarding asset trading channels, JST continued to deepen its layout. In April, the compliant exchange Kraken listed JST/USD and JST/EUR spot trading pairs, followed by Binance listing JST/USDT perpetual contracts, with exchanges like Lbank following suit, significantly enhancing asset liquidity and market recognition.
In the process of bridging traditional finance and the on-chain ecosystem, JustLend DAO also achieved breakthrough progress. As early as the end of June this year, TRON's US-listed company, Tron, completed a staking operation of 365 million TRX via the JustLend DAO platform. This milestone event not only fully validated the platform's industry-leading level in compliance, security, and large-asset handling capabilities but also established JustLend DAO's position as the core channel for traditional compliant capital to enter the TRON ecosystem.
As of December 19th, the Total Value Locked (TVL) on the JustLend DAO platform reached $6.37 billion, consistently ranking among the top three global lending protocols. Within this, the supplied asset size in the SBM lending market reached $3.92 billion; the sTRX liquid staking sector attracted over 9.2 billion TRX; and the Energy Rental service, due to its utility, has covered 72,000 users. These figures fully attest to the platform's strong ecological value and broad user recognition.
SUN.io: Innovative Evolution and Ecological Expansion of the Liquidity Hub
As the largest asset issuance and trading hub within the TRON ecosystem, SUN.io successfully constructed a complete product matrix covering four core businesses—DEX trading, stablecoin swapping, Meme asset issuance, and derivative contracts—through continuous product innovation and iteration in 2025, becoming the key liquidity infrastructure supporting the efficient flow of assets within the TRON ecosystem.
Currently, the SUN.io ecosystem encompasses product components such as the DEX platform SunSwap, stablecoin swapping platforms SunCurve and PSM, the Meme issuance tool SunPump, and the decentralized perpetual contract platform SunX (formerly SunPerp), enabling one-stop access to multi-scenario financial trading services.
In 2025, SUN.io's core businesses flourished across multiple points: its Meme coin issuance platform SunPump continuously activated market liquidity; the newly added decentralized perpetual contract platform SunX filled the derivative service gap, synergizing with the existing spot business to build a diversified service matrix of "spot + derivatives + innovative asset issuance," comprehensively enhancing the breadth and depth of liquidity services.
In core trading scenarios, SunSwap handles approximately 90% of the asset trading volume on the TRON network, with daily trading volume consistently stable above $100 million, providing an efficient channel for capital circulation within the ecosystem. According to official data, on December 30th, the value of crypto assets locked in SunSwap pools was approximately $480 million, with over 25,700 pools created, and the volume processed in the past 7 days exceeded $420 million.
On the innovative asset front, SunPump, with its low-barrier issuance tools and full-chain empowerment system, continuously activated the vitality of the Meme asset ecosystem, repeatedly igniting market fervor and becoming the core engine for ecological traffic growth.
In the derivatives track, SUN.io launched SunX, TRON's first native on-chain perpetual contract platform, in September 2025. This not only filled the gap in ecological derivative services but also redefined the DeFi derivatives service paradigm with institutional-grade risk control standards and low-latency trading experience. According to the latest operational data, SunX's cumulative trading volume has exceeded $16 billion, successfully ranking among the top eleven in the global decentralized perpetual contracts track.
At the token value construction level, the SUN token continues to deepen its deflationary model relying on a revenue buyback mechanism. To date, the cumulative burn of SUN tokens is close to 650 million, of which 362 million came from SunSwap V2 revenue buybacks and 285 million from SunPump revenue buybacks, with the deflationary effect becoming increasingly prominent.
Simultaneously, the global trading layout for the SUN token progressed steadily: in March, it listed on the Hong Kong compliant exchange Hashkey Global, taking a key step towards compliance; in April, it listed on the globally renowned exchange Kraken, significantly enhancing international market liquidity and brand influence; in September, it listed SUN/KRW and SUN/USDT trading pairs on the leading Korean exchange Upbit, with the price surging up to 28% on the listing day, quickly activating incremental demand in the Korean market. These moves not only significantly improved SUN's compliance recognition but also greatly enhanced its market liquidity and global influence.
From DEX trading to Meme ecosystem building, and then to derivative market development, SUN.io has constructed multiple growth curves through continuous product innovation and scenario expansion.
Furthermore, SUN.io is brewing a series of important upgrades, with related progress expected to be announced gradually in the near future.
BTTC: Upgrade Iteration and Token Deflation for Cross-Chain Interconnection
As the core hub of cross-chain infrastructure within the TRON ecosystem, the cross-chain protocol BTTC completed a series of strategic upgrade iterations in 2025, achieving breakthrough improvements in both network security and cross-chain transmission efficiency.
In June of this year, BTTC officially upgraded to version 2.0, reconstructing the underlying cross-chain technical architecture through modular layering and standardized process decomposition design. This version transformed the cross-chain process—"source chain request initiation – information transmission – target chain execution"—into a universal logic and standardized protocol, correspondingly establishing a three-layer architecture: Root Contracts (root chain layer: cross-chain request initiation) – Delivery (relay layer: information transmission) – BitTorrent Chain (execution layer: DApp application runtime platform layer), while also adopting a PoS consensus mechanism. Ultimately, BTTC constructed a secure, efficient, and scalable cross-chain network, providing a solid technical foundation for asset flow and application synergy across multiple chains.
Simultaneously, BTTC 2.0 also optimized the core economic model of the BTT token: by controlling the total supply, it reduced the total BTT supply, enhancing token scarcity; and set a stable staking baseline yield of 6%, allowing BTT holders to participate in network governance and security maintenance through staking. This design increased the participation enthusiasm of BTTC network nodes and network protection capabilities while injecting sustained momentum into BTT's long-term value.
On July 29th, BTTC further launched an upgraded Layer 2 scaling solution, aiming to enhance network scalability and user experience while maintaining decentralization. This solution is compatible with the Ethereum ecosystem, supporting the seamless migration of existing applications and providing users with a high-throughput, low-cost trading environment.
Relying on continuous technological innovation iteration and ecological collaboration, BTTC has been upgraded into a core hub for multi-chain value interconnection: externally, it opens asset transfer channels between TRON and mainstream public chains like Ethereum and BNB Chain, attracting external capital, projects, and users to efficiently flow into the TRON ecosystem. Internally, it provides cross-chain circulation outlets for TRON-based Meme assets, DeFi products, etc., helping them expand into other public chain ecological markets, achieving cross-domain radiation of ecological influence.
WINkLink: The Data Bridge Connecting On-Chain and Off-Chain Worlds
As the core oracle infrastructure of the TRON ecosystem, WINkLink empowers DApps with real-time off-chain data, providing accurate price feeds and verifiable random numbers, building a trust bridge between blockchain and the real world. Leveraging WINkLink, developers can access precise price data and on-chain information, thereby enhancing the security and reliability of on-chain applications like DeFi.
In August this year, WINkLink announced the completion of a comprehensive ecological upgrade, officially opening to global developers. This upgrade will provide higher security levels, more reliable, and scalable on-chain data services for diversified application scenarios on the TRON network, including DeFi, NFT, and RWA.
This year, WINkLink has established integration partnerships with dozens of CEXs and wallets: in the exchange track, partners include MEXC, CoinEX, WEEK, etc.; regarding wallet integration, WINkLink has established deep cooperation with multi-chain wallets like GuardaWallet, Atomic Wallet, Klever, and hardware wallets like ELLIPAL and OneKey, providing users with more secure and seamless Web3 self-custody and on-chain experiences, jointly promoting the scaled application of the TRON ecosystem.
