About

BlackRock BUIDL is a tokenized professional fund share issued as the BlackRock USD Institutional Digital Liquidity Fund token. Qualified or approved investors subscribe through Securitize onboarding and funding instructions; token redemption is handled by transfer-agent book records and off-chain settlement. The fund invests in cash, short-dated U.S. Treasury obligations, repurchase agreements secured by such obligations or cash, and potentially BlackRock government money market funds.

  1. Verifiability orange 4/4 models agree AI-only 3/4 with chat share link
    Ethereum proxy and implementation are verified and a public DSToken repo with Halborn/Cyfrin audit artifacts exists, but repo-to-deployment commit correspondence, current audit scope, and all cross-chain implementation verification were not fully established.
    Verdict

    Choosing orange because the main Ethereum bytecode is verified and public source/audit artifacts exist, but the run did not establish a pinned source commit, bytecode-to-repo match, audit scope for the current deployed contracts, or full cross-chain implementation verification.

    Steelman argument
    Steelman argument The strongest orange case is that the main Ethereum proxy and implementation are verified and a public repo/audit folder exists, but current deployment-to-repo commit matching and complete audit scope were not established.
    Evidence (6)
    V1
    The Ethereum BUIDL proxy ABI endpoint reports verified=true and ABI source sourcify for the proxy surface.
    V1
    The Ethereum implementation 0x603Bb6909Be14f83282E03632280D91bE7fB83b2 is verified as DSToken on Etherscan with exact-match source-code verification.
    V2
    A public Securitize DSToken repository exists and its README describes DSToken v4 architecture, compliance services, trust-service roles, ERC1967 proxy deployment, and audit artifacts, corresponding at a high level to the deployed ABI surface.
    V3
    The repository audit folder lists Halborn and Cyfrin DSToken v4 audit PDFs dated 2025-10-09 and 2025-10-10 respectively.
    V4
    Halborn and Cyfrin are recognizable audit/security firms for Solidity review, supporting audit recognition but not proving current-deployment audit coverage without scope inspection.
    V6
    The Ethereum proxy target() read resolves to the verified implementation 0x603Bb6909Be14f83282E03632280D91bE7fB83b2; however, Avalanche and Polygon surfacer reads did not provide the same complete implementation/source picture in this run.

  2. Control red 3/3 models agree AI-only 3/3 with chat share link
    Ethereum BUIDL proxy ownership resolves to an EOA that can change the implementation target, while privileged token methods include pause, seize, burn, mint-like issuance, feature setting, and service-setting controls.
    Verdict

    Choosing red because the highest reachable tier is T1 and the observed controlling address is an EOA with direct proxy-target and token-admin authority, with no fetched timelock, Safe threshold, governor, or exit-window evidence.

    Steelman argument
    Steelman argument The strongest red case is that a single EOA owns the proxy path and can change implementation target or invoke fund-critical token controls without any fetched timelock or governance delay.
    Evidence (7)
    C1
    The Ethereum BUIDL token proxy owner() read at block 25237812 returns 0xe01605f6b6dC593b7d2917F4a0940db2A625b09e.
    C2
    The Ethereum BUIDL token is a proxy whose target() read at block 25237812 returns implementation 0x603Bb6909Be14f83282E03632280D91bE7fB83b2; the proxy ABI exposes setTarget(address), so the proxy owner controls the target implementation path.
    C2
    Arbitrum and Optimism BUIDL deployments are also proxied and expose upgradeToAndCall in the write-method surface, with owner() resolving to the same 0xe01605f6b6dC593b7d2917F4a0940db2A625b09e address on the fetched surfacer pages.
    C3
    No on-chain timelock, governor, or queued execution stage was found in the fetched owner path; the observed execution path for Ethereum is owner EOA -> setTarget on token proxy, with no delay constant surfaced.
    C4
    The controlling address 0xe01605f6b6dC593b7d2917F4a0940db2A625b09e is shown by Etherscan as an Address page rather than a Contract page, and its transaction history includes direct administrative calls such as Set Target, Issue Tokens, and bridge-address changes.
    C6
    The implementation write-method surface includes pause and unpause, but no time cap or separate emergency governor was established from the fetched ABI/surfacer evidence.
    C7
    The reachable power tier is T1 because the observed owner can change the proxy implementation target and the token implementation exposes fund-critical/admin methods including seize, burn, omnibusSeize, omnibusBurn, issueTokensWithNoCompliance, pause, setDSService, setFeature, and setFeatures.

  3. Ability to exit red 3/3 models agree AI-only 3/3 with chat share link
    BUIDL has no permissionless on-chain redeem/withdraw path; redemption depends on transfer-agent book records and off-chain payment, while token transfer and admin surfaces are permissioned and pausable.
    Verdict

    Choosing red because exit from BUIDL is not an on-chain permissionless withdrawal or claim path; the fetched token ABI lacks redeem/withdraw/claim functions, and the documented redemption path depends on transfer-agent book records and off-chain USD/USDC settlement.

    Steelman argument
    Steelman argument The strongest red case is that there is no on-chain redeem/withdraw/claim function and actual redemption requires an approved transfer-agent process and off-chain payment rail.
    Evidence (6)
    E1
    The fetched Ethereum implementation ABI exposes ERC20 transfer and transferFrom plus privileged burn/seize/issuance methods, but no user-facing withdraw, redeem, requestWithdrawal, claim, or exit function was found.
    E2
    The implementation exposes preTransferCheck and compliance-service hooks, and the DSToken repository states that DSTokens can only reside in EVM wallets owned by authorized investors and can enforce compliance restrictions.
    E3
    The token implementation exposes pause/unpause, while no fetched evidence established an on-chain maximum pause duration.
    E5
    BUIDL redemption is described as an off-chain transfer-agent process: shareholders redeem by moving tokens to the transfer-agent wallet and redemption is effective only if reflected on the transfer agent's books and records by the stated cutoff.
    E5
    The Arbitrum forum disclosure states that redemptions may be made by sending tokens directly to a redemption wallet, but payment is still processed through transfer-agent and fund-administration procedures rather than through an on-chain claim function.
    E7
    Direct on-chain token transfer exists, but the actual exit from fund exposure into cash or USDC is not a permissionless smart-contract redemption; it requires transfer-agent recognition and off-chain settlement.

  4. Autonomy red 3/3 models agree AI-only 3/3 with chat share link
    Impacted TVS: ~100%. BUIDL is an RWA fund token whose principal and redemption performance depend on off-chain fund assets, BlackRock/Securitize/BNY Mellon operational roles, transfer-agent books, banking rails, and discretionary USDC liquidity.
    Verdict

    Choosing red because BUIDL's worst unmitigated dependency affects effectively ~100% of TVS: user principal and redemption depend on off-chain fund assets, custodian/administrator/transfer-agent records, banking rails, and discretionary liquidity facilities rather than autonomous contracts with live on-chain fallback.

    Steelman argument
    Steelman argument The strongest red case is that nearly 100% of BUIDL value is represented by off-chain fund assets and off-chain transfer-agent/custodian/banking processes, so failure of those dependencies can impair principal or redemption.
    Evidence (6)
    A1
    The on-chain token has compliance and service hooks rather than autonomous on-chain asset custody; fetched ABI and repository evidence show external DSService/compliance surfaces but not an on-chain Treasury redemption vault holding the underlying fund assets.
    A2
    Off-chain actors are central to the protocol: BlackRock Financial Management is the investment adviser, Securitize Markets is placement agent, Securitize LLC is transfer agent and technology provider, and BNY Mellon is administrator and custodian.
    A4
    The collateral/value chain is off-chain RWA depth one: the fund invests in cash, U.S. Treasury bills/notes/obligations with remaining maturity of three months or less, repurchase agreements secured by those assets or cash, and potentially BlackRock government money market funds.
    A6
    The fetched disclosure describes possible recovery paths if Securitize becomes bankrupt, including transfer-agent transition or fund closure and return of funds, but those are off-chain processes rather than live on-chain fallbacks that keep users whole automatically.
    A8
    Redemption and ordinary performance depend on transfer-agent processing, banking/wire systems, and for USDC liquidity a discretionary Circle secondary market facility that is expressly not guaranteed.
    A9
    The token owner can change the DSService/compliance-service surface via setDSService and can change implementation target through the proxy owner path; these are governance/admin-mutable external service dependencies with no fetched on-chain exit window.

  5. Open Access red 3/3 models agree AI-only 3/3 with chat share link
    BUIDL admission is contract-level and operationally permissioned: investors must pass Securitize AML/KYC/sanctions approval, and DSToken compliance services restrict token holding and transfers to authorized wallets.
    Verdict

    Choosing red because admission is not permissionless at the contract/product level: BUIDL accepts only approved investors after AML/KYC/sanctions checks, and DSToken compliance rules restrict holding and transfer to authorized wallets.

    Steelman argument
    Steelman argument The strongest red case is that BUIDL has contract-level and operational whitelist/KYC admission: only approved investors and authorized wallets can hold or transfer the token.
    Evidence (7)
    A1
    DSToken documentation states that token rules can restrict retail investors, countries, accredited status, whitelists, and blacklists, and that DSTokens can only reside in EVM wallets owned by authorized investors.
    A1
    The BUIDL disclosure states that the fund accepts only approved investors and requires AML/KYC/sanctions checks and other eligibility criteria.
    A2
    Admission to the fund requires Securitize onboarding and approval; transfer settlement/redemption requires transfer-agent recognition, not merely a permissionless contract call.
    A3
    The official Securitize BUIDL page states that BUIDL is exclusively available on Securitize, which is a publisher/access-path constraint in addition to the contract-level authorization model.
    A3b
    Uniswap/Securitize materials describe DeFi liquidity access for BUIDL, but this does not override the contract-level authorized-investor/compliance restrictions documented for the token.
    A4
    The fetched evidence supports a regulated compliance-service model at token level; exact on-chain blocklist-service address and OFAC-list implementation were not established.
    A5
    Read access is public through explorers and the DeFiPunkd API, but write access to economically meaningful holding/transfer/admission is gated by authorization and compliance checks.

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.

BlackRock BUIDL 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.
