There is an on-chain financial product, external capital may allocate to it, and someone needs to understand what is actually true about it before trusting it.
THE GAP

Institutional capital is arriving on-chain. Operational trust infrastructure is not.

Every institutional buyer of an on-chain investment product asks the same operational questions before allocating. Today, they piece together answers from audit PDFs, docs pages, oracle feeds, and email chains with issuers' investor relations teams. No standardized artifact exists. No continuous verification exists. No procurement-grade evidence layer exists.

01 · CONTROL
Who can change the token, and how fast?
Multisig thresholds, timelocks, upgrade authority, role assignments. All on-chain, but buried in audit reports and rarely surfaced to buyers.
02 · ASSETS
What actually backs the token?
Off-chain custody arrangements, custodian attestations, fund administrator reports. Real, but not standardized across issuers.
03 · ECONOMICS
Where does the return come from, and what does it cost to leave?
Fee schedules, redemption limits and gating authority, loss allocation, and whether the price transacted at is the value an exit realizes. Published in prose across docs pages, never consolidated, and rarely priced end to end.
04 · GOVERNANCE & COMPLIANCE
How has this changed, and what is the regulatory posture?
Signer changes, contract upgrades, registration status, transfer restrictions, KYC and sanctions enforcement. The operational surface a compliance function actually watches.
05 · CONTINUITY
What if the issuer fails?
Bankruptcy-remoteness, security agent attestations, legal-structural safeguards. Traditional finance solved this decades ago.

Plinth's five-pillar framework was benchmarked against published research and diligence methodologies from leading RWA, institutional and crypto-native research organizations, including RWA.xyz, Galaxy Research, Coinbase Institutional, a16z crypto, Messari, Delphi Digital, S&P Global Ratings, Moody's Ratings, LlamaRisk and Particula. The review was repeated independently across multiple AI models to reduce model-specific bias and test consistency of the mapping. While terminology differs across firms, the substantive questions consistently cluster around control, assets, economics, governance and compliance, and continuity.

THE FRAMEWORK

Six evidence classes. One artifact. Every source labeled by what it is.

Plinth is aggregated trust infrastructure. Issuers of on-chain investment products use it to publish a single, standardized trust center under their own domain. Every source keeps its authorship and derivation visible so institutional buyers know exactly what they are relying on.

01
VERIFIED ON-CHAIN
Independently observed
Read directly from public chain state. Control surface, admin authority, governance history, KYC gating, token state. Block-stamped and reproducible.
02
ISSUER-DECLARED
Published by the issuer
Product pages, policy descriptions, address lists, reporting repositories, and legal or regulatory statements published by the issuer.
03
THIRD-PARTY-AUTHORED
Independent author, bounded scope
Material authored by a named third party. Authorship matters, but date, signer, scope, and limitations still constrain what it establishes.
04
PUBLIC-LABEL-INFERRED
Depends on public labels
Conclusions that map public-chain activity to public address labels. Labels can be incomplete, stale, or context-dependent.
05
ANALYST-DERIVED
Calculated from cited inputs
Plinth calculations from reproducible chain data or snapshotted analysis. Derivation and limitations remain visible.
06
ILLUSTRATIVE
Preview, not evidence
Evidence-request templates and product previews. Never presented as a statement about the asset under review.
MISSINGAssessed, but adequate evidence was not identified within the review scope.
NOT ASSESSEDOutside scope or not reviewed. It does not imply the issuer was asked and failed to provide evidence.

BUILT FOR INSTITUTIONAL DILIGENCE · PREVIEW

A cited baseline today. Monitoring and workflow outputs next.

The current OUSG worked example is a frozen, reproducible public-data baseline. The intended workflow adds monitoring, procurement exports, and customer-controlled AI use without blurring the evidence boundary.

CURRENT · CITED SNAPSHOT
Observed Ethereum state, curated public evidence, material gaps, and a reproducible event window in one offline artifact.
PREVIEW · CONTINUOUS MONITORING
Future reviews can refresh on-chain state, document freshness, and material configuration changes against a prior Plinth baseline.
PREVIEW · USE IN YOUR AI
Provide one Trust Center's exported data to a customer-controlled AI with required citations. Cross-asset comparisons, issuer rankings, competitor analysis, and investment recommendations remain out of scope.
PREVIEW · DILIGENCE OUTPUTS
Evidence packs, decision-memo appendices, alerts, and API access are product directions. They are not active controls in this static mock.
WHY INDEPENDENT

A cross-platform standard cannot be owned by any single platform.

Trust standards work when they are structurally independent from the parties they measure. Plinth is designed for exactly that role in on-chain investment products. Infrastructure any issuer can adopt, on any platform, verified by methodology that anyone can reproduce.

NO PROTOCOL MONEY IN THE CAP TABLE
Investors are structural, not the entities being attested. No commercial capture on either side of the trust relationship.
PUBLIC METHODOLOGY
Framework, tag taxonomy, and verification procedures are open. Anyone can reproduce every Layer 01 value from public identifiers.
PLATFORM-AGNOSTIC BY DESIGN
No exclusive integration with any issuance platform. Any issuer on any platform can publish to the same framework.
SINGLE-PURPOSE INFRASTRUCTURE
Trust artifacts are the only product. No bundled feeds, no cross-sold services. Every issuer relationship is pure infrastructure.
CONVERSATIONS

If you're building institutional infrastructure for on-chain investment products, we should talk.

We are looking for issuer-side evidence partners and allocator-side risk, ODD, or procurement partners who will review the Compliance and Continuity evidence boundaries with us.
