BUIDL trust rating since coverage began
Score history not yet available.
The chart will appear once 4 more daily readings have been collected (10 of 14 so far).
What closes the gap — and who closes it
- ·BUIDL pays yield via monthly distribution events (new tokens minted), not price appreciation.
- ·There is no onchain rate to compare against the published one.
- ·Score component reflects this structural property.
What would close it
Yield in this instrument is paid by minting new tokens to holders each month rather than rising in price. A daily on-chain rate to measure against the issuer's published one therefore does not exist by design.
BUIDL redeems through Securitize authorized channels, not DEX trading. The Liquidity rubric does not apply cleanly to this instrument type.
What would close it
A liquidity rubric tailored to authorized-redemption funds — depth of authorized off-chain redemption channels rather than DEX depth.
- ·BlackRock / Securitize files SEC Form D / D/A under CIK 0002013810.
- ·Filing cadence is very low (2 filings since inception).
- ·No machine-readable per-token attestation feed exists.
What would close it
Issuer publishes a recurring BUIDL reserve attestation at a public URL with at least monthly cadence.
BlackRock USD Institutional Digital Liquidity Fund Ltd. files Form D / D/A only. 2 filings since inception — very low cadence relative to other issuers in this tier.
Score impact: attestationFreshness: stub. Scores at regulatory baseline only. Revisit when fund files 10-K or N-CSR.
- ·contractOwner (item 25, Read as Proxy) returned a plain EOA — no Contract tab on Etherscan.
- ·Securitize DS Protocol transparent proxy.
- ·Single EOA controls upgrades.
Score impact: governance sub-signal: 4/10 (single EOA). upgrade_pattern transparent_proxy: 3/15. Total governance: 7/25.
Top holder is the Securitize custodian address. Single-custodian concentration is structural for BUIDL's permissioned distribution model — not a measurement gap.
What would close it
A concentration rubric for permissioned distribution funds, which treats the issuer's custody address differently from third-party concentration.
No Etherscan label. Funded via OKX. 1 transaction total. Dormant wallet.
Score impact: Kept in.
- ·No Etherscan label.
- ·Funded via Coinbase.
- ·25 transactions.
- ·$54.5M position.
- ·Pattern consistent with institutional wallet but not identifiable as protocol infrastructure.
- ·No Contract tab.
Score impact: Kept in. Below 90% exclusion threshold.
TransparentUpgradeableProxy (OpenZeppelin v5.1.0) source verified on Etherscan Contract tab. Protocol infrastructure contract holding 8.85% of BUIDL supply.
Score impact: Excluded from top-10 concentration calc. Post-exclusion top-10: ~73.93% → 5/25.
- ·No Etherscan label.
- ·Active DeFi user — Morpho Bundler calls observed.
- ·Retail or institutional DeFi user, not protocol infrastructure.
Score impact: Kept in.
- ·No Etherscan label.
- ·Plain EOA.
- ·Outgoing transactions labeled "BlackRock: BUIDL Token" as counterparty — strongly suggests institutional position managed by BlackRock, but below 90% confidence without a direct label on this address.
Score impact: Kept in. If confirmed as BlackRock treasury/custody this would be excluded, improving the concentration score.
BUIDL is scored across the same four dimensions as every other rated instrument in its class — Disclosure Quality, Redemption Liquidity, Structural Trust, and Holder Concentration. Each dimension contributes up to 25 points. The dimension breakdown above shows where the score comes from; the diligence trail shows every verified fact behind it.
