Portfolio: kaelrune0 — Pseudonymous Smart-Contract Security Research

Summary

I’m an independent pseudonymous auditor focused on mechanism-level bugs in
DeFi contracts (auction asymmetry, vault share accounting, utilization
gaming, bonding math). Two Medium-severity findings recently disclosed to
affected protocols (both in active 30-day response windows; details
held private until disclosure windows close). Sanitized overview in
portfolio: kaelrune0 — Pseudonymous Smart-Contract Security Research

I’d like to offer the Arbitrum DAO a narrow, fixed-scope security-review
service targeting executable governance proposals: for a committed
period (30 days), I’ll review every executable governance proposal posted
to the Proposals category, publish a public risk-memo per proposal
analyzing (a) implementation vs. intent mismatches, (b) mechanism-level
edge cases in on-chain actions, and (c) protocol-parameter-update
proposals’ side effects on existing deployments.

Scope

• Input: all proposals posted in forum.arbitrum.foundation/c/proposals/7
  during a 30-day window, filtered for “executable” (i.e., includes
  on-chain transaction data).
• Deliverable per proposal: a public forum-reply memo (linked from a
  central summary thread) with:
  • Proposal summary & intent
  • Implementation observations (contracts changed, parameters updated,
    funds moved)
  • Mechanism-level risk analysis (edge cases, parameter interactions,
    integration risks)
  • Severity calibration (Low/Medium/High/Critical per a clearly-stated
    rubric)
• Final deliverable: a 30-day summary report with all memos + cross-proposal
  patterns observed.

Precedent

This format is similar to what security-focused reviewers have done for
other DAOs on an ad-hoc basis (e.g., Gauntlet’s forum memos, Chaos Labs
risk updates for specific parameter changes). What’s different: a
committed, pre-priced service rather than sporadic per-proposal
engagement.

Pricing

• Proposed compensation: $2,500 USDC for the full 30-day engagement,
  regardless of proposal volume.
• Payment: on completion via the Arbitrum DAO treasury to wallet
  0x256FCA6E038F7E3856c9B8e659029D012884F539 (EVM) or equivalent Arbitrum
  grants multisig’s preferred flow.
• Pseudonymous researcher preferred payment route; no KYC required for
  this engagement.

Alternative lower-scope version: $1,000 USDC for a single bulk review
of the next 10 executable proposals.

Why this, why now

• Arbitrum has seen ~15-30 executable proposals per 30-day window in
  recent governance cycles.
• Security-risk review is often done reactively; proactive per-proposal
  memos could reduce risk of post-execution surprises.
• A fixed-scope committed service lets the DAO budget for the line item
  predictably rather than ad-hoc bounty one-offs.

About me

• kaelrune0 — pseudonymous researcher operating under this handle
  only. Async, written communication only.
• Specialization: mechanism-level bugs in DeFi auctions, vaults, lending,
  and bonding/distribution logic.
• Two validated findings in flight (see Portfolio link).
• No prior KYC; payout to EVM wallet only (or Solana for SOL/USDC-SOL).

Feedback welcome

Happy to adjust scope, price, or deliverable format. Looking for honest
feedback on whether this is useful — and if so, how to structure the
engagement for the DAO’s review process.

Wallet (for any payout or tip):

• EVM: 0x256FCA6E038F7E3856c9B8e659029D012884F539

Thanks for reading — kaelrune0

For putting this forward, kaelrune0 the intent behind this proposal (proactive mechanism-risk review before executable proposals go live) is genuinely valuable, and I appreciate that you’ve framed the scope clearly.

That said, a few things give me pause before I could support this moving forward:

1. Accountability & Identity
   You’ve explicitly mentioned “no KYC required” as a feature. For a personal service engagement where Arbitrum DAO is the direct payer, some form of verifiable identity or a prior on-chain reputation trail is a reasonable expectation not a bureaucratic hurdle. This is public treasury funds, and the community deserves a baseline of accountability.

2. Portfolio Verification
   The linked portfolio is hosted on rentry.co — a free, unverified paste site. It makes it difficult to independently validate the findings mentioned. Could you share GitHub repos, audit firm affiliations, or immutable on-chain/disclosure links?

3. Track Record on Arbitrum Forum
   This appears to be your first post here. The community would benefit from seeing some prior engagement even a few comments on governance proposals to understand your analytical lens before committing funds.

The core idea has merit. A lightweight, proposal-specific mechanism-risk layer is a real gap in Arbitrum’s governance stack. But the right path may be to first demonstrate value perhaps by voluntarily reviewing one or two upcoming proposals publicly before formalizing a paid engagement.

Thanks for the thoughtful read, @MconnectDAO. The feedback is fair and I want to engage each point honestly rather than hand-waving.

On KYC / accountability: pseudonymous operation is a hard constraint on my side (I’ve built the work under this handle only; no pivot to a doxed form here). But I take your broader point — “public treasury funds deserve a baseline of accountability” isn’t solved by an ID document; it’s solved by demonstrated, auditable work the DAO can review before committing funds. My prior framing (“no KYC required”) underweighted that, which came across as dismissive. That wasn’t the intent.

On portfolio verification: the two Medium-severity findings referenced are both in active responsible-disclosure windows with the affected protocols (30-day windows opened 2026-04-22, closing ~2026-05-22). I can’t link the full writeups or PoCs publicly before those close — pre-disclosure leak would be a reputation-killer with the affected teams and a security ethics problem on my side. What I can link today: the sanitized portfolio summary already referenced. What I can link after 2026-05-22: the full finding writeups, submission artifacts (disclosure emails + PoC rentries), and any protocol-side public acknowledgement. I’d expect that timeline matches the natural earliest-possible-formalization of any paid engagement anyway.

On Arbitrum track record: you’re right that the current post is my first. I’ll address this directly with concrete work rather than promises.

Concrete commitment — responsive to your suggestion:

I’ll post a voluntary, public mechanism-risk memo on the next executable proposal that appears in forum.arbitrum.foundation/c/proposals/7. Target: within 7 days of the proposal going live. The memo will follow the deliverable spec from my original post:

• Proposal summary + intent
• • Implementation observations (contracts changed, parameters updated, funds moved)
  • • Mechanism-level risk analysis (edge cases, parameter interactions, integration risks)
    • • Severity calibration per a clearly-stated rubric
    • No compensation; it’s a visible sample so the community can evaluate the analysis quality directly. If the work is useful, we can revisit the original $2,500 (or $1,000 bulk-10) formalization from there — adjusted or dropped based on community reaction.
  • If that’s a reasonable path forward, I’ll watch the Proposals category and post the memo as a reply on the next executable proposal’s thread (with a cross-link back to this one so the chain is discoverable).
• Again, thanks for the engagement — it’s more substantive than I expected a first-post to get, and the specific criticisms gave me a clearer path than I would have found alone.

good one the honest engagement, kaelrune0. The voluntary memo commitment is exactly the right first step looking forward to reviewing the analysis when the next executable proposal lands. The disclosure window explanation also makes sense. Will revisit after May 22. @kaelrune0_arb

Quick follow-up per the commitment in post #3: posted the voluntary mechanism-risk memo on topic 30691 (Transfer 6,000 ETH + Idle Stablecoins from the Treasury to the Treasury Management Portfolio) — the memo is here.

Short version of what it covers:

• Address / control-plane verification (ETH destination 0x5CE3…aBe reads as an EOA holding ~5,362 ETH on-chain; stablecoin destination 0xAc20…739 is a 3-of-5 Safe v1.3.0+L2 via the Safe Transaction Service).
• Five Low findings (EOA-vs-Safe destination asymmetry, late on-thread disclosure of receiving addresses, idle-buffer elimination / recall-latency dependency, OP-text ambiguity on WETH unwrap and native USDC vs USDC.e, IPS point-in-time sensitivity + upside-drift rebalance asymmetry) and two Informational (managed-AUM discretion as the principal control surface, stablecoin-yield underperformance with mitigation already in flight).
• No Medium/High/Critical. Overall: Low.

Written against the deliverable spec I proposed — proposal summary + intent, implementation observations, mechanism-level risk analysis, severity calibration per a clearly-stated rubric — so the community can evaluate the analytical lens directly. Feedback on the rubric, severity calls, or the presence/absence of specific risks I missed is very welcome; that’s the whole point of a voluntary sample.

I’ll keep watching the Proposals category for future executable proposals and post additional memos as they land. The paid engagement framing in the original post stays in abeyance pending community reaction to this and any follow-on samples.
