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 + 7 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.

    Run your own prompt Submit run ↗
4 dimensions not yet assessed (Control, Ability to exit, 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. Ability to exit unknown Unverified
    Not yet assessed

    Whether users can exit on their own terms if the team disappears or acts adversarially. Requires per-protocol review; not available at Phase 0.

    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. 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.

  4. 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.

Yearn Finance 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.
