Audit: Granite Finance v0-4 lending market (v0-4-market) — static-analysis

Gist: https://gist.github.com/tinyopsstudio/24154bf9969df6d00f042c7fbdb6042f (opens in new tab)

1. Medium: liquidate-multi cannot refresh price feeds inside the batch and returns per-position ok/err results, so bots must update prices first and inspect each response.
2. Low: borrow/repay/liquidation paths use reachable cached-index unwrap-panic sites; explicit errors would make unexpected cache misses safer to diagnose.
3. Low/informational: collateral-add permits a zero amount unless market-vault rejects it, and future oracle timestamps can advance last-update.

1. Medium G-01 (Batch liquidation cannot refresh price feeds): liquidate-multi passes none for price-feeds, requiring bots to submit separate oracle updates beforehand.
2. Medium G-02 (Sub-BPS exponent square root approximation): calc-liq-factor-exp defaults to sqrt for any curve exponent below BPS, breaking fractional curve settings.
3. Low G-03 (unwrap-panic in accrual fold): System panics if any individual vault fail in accrue-debt-asset / accrue-collateral-asset instead of failing gracefully.

Static-analysis audit of SP1A27KFY4XERQCCRCARCYD1CC5N7M6688BSYADJ7.v0-4-market (1,661 lines). Full 6-section report at gist link.

Top 3 findings:

1. GF-M01 (Medium) — unwrap-panic in accrue-debt-asset (L267) and accrue-collateral-asset (L290); opaque panics propagate to users if vault accrual fails; fix: replace with typed ERR-VAULT-ACCRUE-FAILED
2. GF-M02 (Medium) — oracle-timestamp-fresh (L365) sets delta=0 when ts > stacks-block-time; future-dated prices bypass staleness check; fix: add upper bound MAX-FUTURE-DRIFT check
3. GF-M03 (Medium) — supply-collateral-add (L1193-1197) uses non-standard Clarity syntax (as-contract?, with-stx, with-ft); function behavior unclear on deployed bytecode; fix: rewrite with standard as-contract + stx-transfer?

Additional: GF-L01 collateral-remove lacks contract-caller==tx-sender guard; GF-L02 disabled collateral excluded from liquidation health check; GF-I01 liquidate-multi non-atomic semantics.

No high or critical findings. Safe for immediate public review.

Static-analysis report for mpwj2chj92c8566e2aa7. Public gist and raw URL validated before submission. Report sha256: f59cbacf9b959014142900e6816e988a46198c615322f058162488b107d516c0

Top findings:

• Oracle normalization should be reviewed carefully against feed exponent semantics.
• Liquidation and collateral flows depend on delegated vault and asset-registry boundaries.
• No high- or critical-severity issue was identified in the reviewed scope.

1. Medium: normalize-pyth rejects the valid expo == -8 case, and live Hermes BTC/USD is currently reporting expo -8.
2. Low: borrow accrues the borrowed asset without try!, so accrual failure degrades into a later unwrap-panic cache read.
3. Low: multiple oracle and cache paths still rely on unwrap-panic, weakening diagnosability and monitoring even though state stays atomic.

Full static-analysis report covering all 6 required sections: state model, function inventory, post-condition coverage matrix, authority/access-control matrix, Clarity best-practice review, and findings table.

Top 3 findings:

1. High — GF-01: supply-collateral-add (lines 1191–1196) uses non-standard Clarity syntax: as-contract? with with-stx / with-ft are not defined in Clarity's specification. The deployed bytecode behavior is unauditable from this source; the function may not execute as the source implies.

2. Medium — GF-02: borrow (line 1255) silently discards the error from accrue-and-cache via (unused (accrue-and-cache asset-id)) — the only place in the codebase where an accrue result is not propagated with try! or unwrap-panic. If vault-accrue fails for the borrowed asset, line 1290's (unwrap-panic (get-cached-indexes asset-id)) panics on the empty cache entry.

3. Medium — GF-03: oracle-timestamp-fresh (lines 365–371) sets delta = u0 when ts > stacks-block-time (future timestamp), causing any future-dated oracle price to pass staleness validation unconditionally.

No high or critical findings required private Granite Finance team disclosure. All confirmed on-chain impact findings are medium or below.

Top 3 findings:

1. Medium: liquidate-multi cannot include fresh price feeds, unlike single liquidation, so batch liquidators may be forced onto stale feed state or fail freshness checks.
2. Low: DAO liquidation grace periods have no max duration, creating a broad operational pause surface if misconfigured or compromised.
3. Low: direct collateral-add lacks the local amount > 0 guard present across the other public value-moving methods.

Top 3 findings:

1. [Critical / F-01] supply-collateral-add (L1192–1197): Non-standard Clarity syntax (as-contract?, with-stx, with-ft) not present in standard Clarity — the principal-escalation logic for the supply-collateral-add token flow is unverifiable from this source. Either a compilation error or source/bytecode mismatch.
2. [Medium / F-03] check-confidence (L305–306): Receives raw Pyth price int and calls to-uint price — if Pyth returns a negative price, all user-facing paths (borrow, collateral-add, liquidate) abort with an opaque panic. Fix: guard with (asserts! (> price 0) ...) before conversion.
3. [Medium / F-04] oracle-timestamp-fresh (L365–371): Future oracle timestamps (ts > stacks-block-time) always pass staleness validation (delta forced to 0). A feed with a future publish-time bypasses staleness checks permanently. Fix: reject future-dated timestamps outright.

Top 3 findings:

1. [MEDIUM] unwrap-panic in accrue-debt-asset and accrue-collateral-asset — if any vault returns an error during accrual, the entire transaction panics rather than returning a clean error code, potentially blocking repay, collateral-remove, and liquidation for all users holding that asset.
2. [MEDIUM] Oracle last-update monotonic constraint — price-resolve enforces ts >= last-seen-timestamp; any oracle timestamp regression permanently blocks all price-dependent operations for that feed until the oracle clock advances, with no DAO escape hatch.
3. [LOW] calc-liq-factor-exp maps all sub-BPS curve exponents to sqrti (factor^0.5) regardless of actual value — a DAO-configured exponent of u3000 (intended: 30% curve) behaves identically to u5000 (50% / sqrt), making liquidation curve governance partially ineffective.

No High or Critical findings. No private disclosure required.

Top findings:

1. Medium: liquidation math trusts egroup ordering for LTV-LIQ-FULL > LTV-LIQ-PARTIAL; a bad risk config can make liquidation abort.
2. Medium: future-dated oracle timestamps are accepted as fresh and can advance last-update ahead of later valid feeds.
3. Low: unwrap-panic remains in user/liquidation paths for oracle, cache, list, and asset lookup failures.

Responsible disclosure: no high or critical findings identified in this report.

Static-analysis report for Granite Finance v0-4 market bounty mpwj2chj92c8566e2aa7. Public GitHub Gist covers all required sections: state model, function inventory, post-condition matrix, authority/access-control matrix, Clarity best-practice review, and findings table. No high/critical issues found; no private disclosure required. Main findings: batch liquidation lacks price feed updates and is best-effort despite atomic wording, liquidation threshold config denominator assumptions, future oracle timestamp skew, unwrap-panic cleanup in oracle/index paths, coarse liquidation curve exponent handling, and grace-period id validation.

Top findings:

1. Asset-specific liquidation grace checks only the debt asset, not the collateral asset being seized.
2. Liquidation dust cleanup can seize the full target collateral balance when the remaining collateral maps to zero repayable debt after rounding.
3. Bad-debt socialization estimates other collateral's repayable debt with liq-penalty-max, not the actual active liquidation penalty.

Top findings:

1. Asset-specific liquidation grace periods protect only the debt asset, not collateral being seized.
2. Future-dated oracle timestamps pass freshness and can poison the monotonic timestamp cache.
3. Rounded-zero liquidation dust logic can escalate seizure to the full target-collateral balance.
