Deep Dive
1. USDJ Sunset Plan Finalized (August 2025)
Overview: The JUST ecosystem formally concluded its USDJ stablecoin service. This required all users to repay loans and withdraw collateral by the final deadline to avoid automatic liquidation, marking a strategic shift away from the legacy stablecoin.
The plan involved progressively disabling minting and borrowing features throughout 2025. Official liquidity support ended on 31 August 2025, after which the USDJ exchange rate was allowed to float. This was not a code patch but a major operational wind-down of a core system component.
What this means: This is neutral for JST as it streamlines the ecosystem's focus. It removes the maintenance burden of an older stablecoin system, allowing resources to be directed toward newer, more efficient products like USDD. Users had to actively manage their positions to avoid losses.

2. Energy Rental Cost Reduction (September 2025)
Overview: JustLend DAO reduced the base rate for its Energy Rental service from 15% to 8%. This change directly passed on lower network energy costs to users, making transactions and smart contract interactions significantly cheaper.
This update followed a reduction in the TRON network's energy cost itself. It optimizes the cost structure for users who rent energy to pay for transactions or who earn yield by renting out their own idle energy resources.
What this means: This is bullish for JST because it improves the user experience and affordability of the TRON DeFi ecosystem. Cheaper transactions can attract more users and increase protocol activity, which in turn generates more revenue that can fund future JST buybacks.

3. Quarterly Buyback & Burn Execution (January 2026)
Overview: The DAO executed its scheduled second large-scale buyback and burn, removing 525 million JST tokens from circulation. This action is part of a structured, revenue-driven deflationary model funded by protocol earnings.
The model automatically allocates a portion of net income from lending, staking, and other services to repurchase and permanently burn JST tokens. This event brought the total burned supply to over 1.08 billion JST, or nearly 11% of the original total supply.
What this means: This is bullish for JST because it directly reduces the token's circulating supply using real protocol profits. Scarcity created through verifiable, recurring burns can provide long-term support for the token's value, aligning holder incentives with ecosystem growth.

Conclusion
Recent JUST developments focus on strategic ecosystem refinement and enforcing a disciplined, revenue-backed deflation model for JST, rather than public-facing code releases. How will the continued execution of its buyback mechanism influence JST's scarcity against the backdrop of broader TRON DeFi adoption?
