JustLend

The core Compound V2-style money market. Users supply TRX or TRC-20 assets (USDT, USDD, etc.) to receive interest-bearing jTokens, then over-collateralize to borrow other assets at algorithmic floating rates. As of the June 2026 upgrade the market moved to SBM V2, an isolated-collateral design with a dual-layer Vaults/Markets structure and an Adaptive Curve interest-rate model so that liquidations in one market no longer cascade across the whole protocol.

A one-click TRX liquid-staking feature launched April 2023 under TRON's Stake 2.0. Users stake TRX to receive the sTRX TRC-20 token; JustLend handles Super Representative voting and reward claiming and automatically rents out the resulting TRON Energy, letting stakers earn voting + energy-rental yield. The Energy Rental market lets counterparties rent Energy at roughly 50-80% below the cost of burning TRX for transaction fees.

The protocol relies on a price oracle to value collateral and trigger liquidations. CertiK's audit flagged oracle design and centralization of oracle/admin controls as the primary risk areas, an important consideration given assets are valued via feeds the protocol admins configure.

JST, the TRC-20 governance token shared across the JUST/JustLend DAO ecosystem (max supply 9.9B), governs every protocol parameter. Holders propose, vote, and execute on-chain through GovernorBravo and a Timelock contract. A revenue-driven JST buyback-and-burn mechanism was activated in October 2025, converting protocol revenue (including USDD profits) into permanent JST burns.
