About

JustLend is a decentralized money market protocol on TRON based on Compound V2 architecture. Users supply TRC20 tokens or TRX to mint interest-bearing jTokens, which can be redeemed at any time for the underlying asset. Borrowers can take loans against collateral subject to algorithmic interest rates and liquidation at 100% risk value. Governance is conducted by JST token holders through on-chain proposals with timelock execution.

Risk analysis

One card per dimension, sorted by severity. Only Verifiability and Autonomy carry automated signals in Phase 0. See methodology for scope.

Audit a dimension yourself · DEFI@home Contribute an LLM-run assessment — any model, any dimension. Three agreeing runs merge automatically into the public record.

DEFI@home is a distributed audit network modeled on SETI@home: instead of CPU cycles, it crowdsources LLM reasoning. Paste a slice prompt into Claude, ChatGPT, Gemini, or any browsing-capable model, and submit the JSON output as a pull request. The quorum bot merges it once ≥3 independent runs (from different models) reach the same grade — no single model, and no single contributor, can move the needle alone. How it works →

  1. Verifiability tentative
    Open source + 5 audits

    Protocol publishes a GitHub repository and has at least one audit on record. This is a coarse Phase-0 signal only: auditor reputation, scope, and post-audit review coverage are not yet weighted.

  2. Ability to exit 1/3 model submitted
    Permissionless exit architecture inherited from Compound V2, but TRON chain prevents on-chain state verification
    Tentative grades
    • claude-sonnet-4-5 (autorun) unknown

    No quorum yet — verdict and steelman hidden until ≥3 models agree.

    Evidence (7)
    E1
    User exit functions identified: redeem(uint redeemTokens), redeemUnderlying(uint redeemAmount), and repayBorrow(uint amount) in the CToken contract. These allow users to withdraw supplied assets and repay debts.
    E2
    The redeem and repay functions call comptroller.redeemAllowed() and comptroller.repayBorrowAllowed() respectively for collateral/liquidity checks, but no pause guards are present in the CToken.sol source code. The Compound V2 architecture pattern explicitly prohibits pausing redeem and repay operations.
    E3
    No pause mechanism found in the documented redeem/repay flow. The Comptroller documentation describes collateral factor and liquidation checks but does not reference pause functionality for withdrawals.
    E4
    Governance operates via JST token-weighted voting through GovernorBravo with a Timelock contract. External source reports minimum 48-hour timelock delay, though this could not be verified on-chain due to TRON chain limitation.
    E5
    No queued redemption or daily withdrawal cap mechanisms found in the CToken contract or documentation. Standard Compound V2 architecture allows immediate withdrawals subject to liquidity and collateral constraints.
    E6
    No emergency escape-hatch or forced-exit mechanism documented beyond the standard redeem/repay functions.
    E7
    Documentation confirms exit functions are directly callable on-chain via TronScan or wallet interfaces. The interface repository notes that users can access the protocol without the official frontend.
    Why is this slice uncertain?
    • only 1 of 3 model submissions on record — quorum requires ≥3 agreeing models

    A fresh independent run can establish (or overturn) a verdict.

3 dimensions not yet assessed (Control, Autonomy, Open Access)
  1. Control unknown Unverified
    Not yet assessed

    Who holds admin privileges, how contracts can be upgraded, and how quickly. No automated heuristic grades this at Phase 0; a real assessment arrives when onchain discovery reads roles, owners, and timelocks.

    No model has graded this dimension yet. Run the slice prompt through any LLM and submit the JSON — once ≥3 independent runs agree, the quorum bot merges the verdict here.

  2. Autonomy unknown Unverified
    No Phase-0 autonomy signal

    Neither the category heuristic nor the forkedFrom signal fires for this protocol. A real autonomy graph (oracles, bridges, fallbacks, governance-mutable dependencies) arrives with Phase-2 onchain discovery.

    No model has graded this dimension yet. Run the slice prompt through any LLM and submit the JSON — once ≥3 independent runs agree, the quorum bot merges the verdict here.

  3. Open Access unknown Unverified
    Not yet assessed

    Whether the protocol depends on privileged operators, whitelists, geo-restrictions, or off-chain infrastructure. This is not a signal DeFiLlama carries in a usable form; crawler-based detection lands in a later phase.

Stage

Preview of the Phase-3 maturity framework. DeFiPunk'd will adopt DeFiScan v2's stages verbatim; the section is rendered below in its intended shape so the structure is visible today.

JustLend has not yet been assessed under the DeFiScan v2 stage framework.
The walkaway test is the central criterion. Once stages land, protocols reach Stage 1 only if users can exit in the presence of malicious operators even when the emergency council disappears.
Scope of assessment
Stages are assessed per-protocol against DeFiScan v2's criteria: governance structure, upgradeability path, timelock durations, emergency-council scope, and the walkaway test. The analysis depends on onchain discovery (roles, owners, timelocks) and deeper review of deployed contracts — neither of which DeFiPunk'd automates at Phase 0.
Stage 0 requirements pending
Governance is largely off-chain, contracts are upgradeable with short or no timelock, and the protocol depends on a multisig or team with full discretion. At Phase 0 DeFiPunk'd does not automatically evaluate these; the assessment lands with crawler-based onchain discovery.
Stage 1 requirements pending
Users can exit or opt out on their own terms even if the team disappears. Upgrades run through a meaningful timelock with an emergency security council clearly scoped. The walkaway test is the headline criterion.
Stage 2 requirements pending
Protocol is fully permissionless and immutable, or upgrades require a supermajority of token holders with a long timelock and no emergency override. This is the terminal stage of the DeFiScan v2 framework.

Stages are an opinionated assessment of maturity, not a rating of security or safety. A protocol can sit at Stage 2 and still carry substantial technical or economic risk; the framework exists to incentivize decentralization, not to rank protocols.

Contract surface

Every contract in scope for this protocol — pooled from DeFiLlama's TVL adapter (mechanical) and DEFI@home discovery submissions (LLM-curated). Verified-source flags come from Etherscan + Sourcify; owner / multisig metadata is read on-chain when available. Reviewer audit context, not a slice score. A lending protocol's adapter set will list third-party collateral tokens alongside its own contracts; attribution is the grader's job.
