/// The Problem
A $16 trillion market with fragmented identity infrastructure
Repeated KYC Across Every Platform
Investors must re-verify identity on every RWA platform, every blockchain. No portable compliance credentials exist today.
A user verified on Platform A must re-onboard on Platform B. Assets lose compliance context when they move. Institutions repeatedly verify the same entities.
5-7x
Average re-verifications per user
Fragmented Multi-Chain Identity
Verification on Ethereum doesn't transfer to Solana. Each chain requires separate compliance infrastructure — costly duplication.
Different enforcement semantics per chain. Bugs introduced during migrations. Inconsistent regulatory outcomes for the same asset.
100%
Duplication across chains
$274 Billion Annual Compliance Spend
Banks spend $30-500M/year on KYC alone. Traditional finance identity systems don't support blockchain rails.
Hard-coding compliance rules into application or contract logic makes change slow and risky. Code must be updated under regulatory pressure. Assets require retroactive fixes.
$274B
Annual TradFi compliance spend
No Cross-Chain RWA Standard
Each platform builds proprietary token standards. No interoperability for regulated securities across chains.
Counterparties cannot rely on opaque internal logic. Regulators require traceability: who decided, under what policy, and why.

/// The Solution
Signum: The identity layer for tokenized assets
"Sign in with Signum"
OAuth2/OIDC identity provider for Web3. One verification, portable across all platforms and chains.
Standards-based authentication (OAuth2/OIDC)
Single verification, universal access
Returns proof of compliance — not personal data
Privacy-preserving by design
Multi-Chain Attestations
KYC, accreditation, and compliance credentials propagate automatically across Solana, Ethereum, Arbitrum, Base, and Hyperliquid via LayerZero V2.
LayerZero V2 OApp cross-chain attestation sync
Full-mesh chain topology — every chain messages every other
Revocable, expirable, and upgradable credentials
Policy updates propagate through Kafka event bus
Platform-Managed Wallets
PDA-based custody on Solana with Token 2022. Full issuer control with Transfer Hook compliance enforcement.
Program Derived Address (PDA) custody
Token 2022 Transfer Hook integration
Issuer-controlled compliance at protocol level
Zero additional latency
Signum Asset OFT
Cross-chain RWA framework built on LayerZero OFT standard with compliance-gated transfers, holder tracking, and regulation enforcement.
LayerZero OFT (Omnichain Fungible Token) standard
Compliance-gated _debit() and _credit() hooks
Per-asset regulation enforcement (RegD/RegS/RegA)
vLEI integration for institutional identity
/// Identity to Asset Flow
One Identity. Every Chain. All Assets.
Individuals and institutions create verified identities, access compliant RWA marketplaces, and seamlessly transact across chains.
Create Verified Identity
Users and institutions complete KYC/AML through Signum. A single verification creates a portable compliance credential.
Issue On-Chain Attestations
Compliance credentials are issued as on-chain attestations and propagated across all supported chains via LayerZero V2 messaging.
Access Compliant Markets
Verified identities unlock access to tokenized RWA marketplaces. Compliance travels with the identity, not the platform.
Enforce at Transfer
Transfer hooks validate compliance before every transaction. Non-compliant transfers are rejected atomically at the protocol level.
Supported Networks
Attestations propagate via LayerZero V2 messaging
/// Compliance Enforcement

SignumComplianceOApp and Transfer Hooks enforce compliance before every transaction. Unverified users, restricted jurisdictions, and non-compliant transfers are automatically blocked on-chain via LayerZero V2.

/// Why Signum Exists
Unified Compliance
for a fragmented world.
Compliance is siloed, but regulated finance is networked
What breaks
A user verified on Platform A must re-onboard on Platform B. Assets lose compliance context when they move.
Why Signum
Identity is verified once. Compliance is expressed as portable attestations. Assets enforce eligibility regardless of venue.
This is the same structural problem OAuth solved for authentication — applied to regulated execution.
Internal compliance logic does not scale across counterparties
What breaks
A platform can assert "This user is compliant" — but that assertion holds only while assets are single-issuer and settlement stays internal.
Why Signum
Compliance decisions are issued by a neutral authority. Enforcement rules are deterministic and inspectable.
Signum replaces implicit trust with verifiable policy.
Enforcement fragments across chains
What breaks
Most platforms implement compliance once for a primary chain, then again — differently — for every additional chain.
Why Signum
A single compliance model powered by LayerZero V2 OApp messaging. Chain-specific adapters. Identical eligibility rules everywhere.
This is infrastructure leverage — not feature work.
Compliance logic hard-codes regulation that is guaranteed to change
What breaks
Hard-coding rules into application or contract logic makes change slow and risky. Errors carry legal consequences.
Why Signum
Attestations are revocable, expirable, and upgradable. Policy updates propagate through events. Assets respond automatically.
Compliance shifts from static code to dynamic policy.
“If Signum ever becomes optional at execution time, it has lost its reason to exist.”
/// Who Signum Is For
Built for infrastructure platforms.
Benefiting the entire ecosystem.
Primary Customers
Tokenization Platforms
Infrastructure distributing regulated assets that need compliance to be deterministic, enforceable, and composable.
e.g. AVKIRWA Issuance Systems
Platforms managing the lifecycle of real-world asset tokens — from minting to secondary trading.
Issuance & lifecycleSettlement & Clearing
Regulated settlement layers requiring verified counterparty identity before atomic settlement.
Institutional railsCustody & Asset Rails
Institutional custody providers needing chain-level compliance enforcement for asset movements.
Multi-chain custodyDownstream Beneficiaries
Signum sells to platforms, not directly to retail users or banks. These entities benefit indirectly.
Emerging Use Cases
Domains where policy-gated execution is becoming necessary — Signum will expand here once the RWA foundation is proven.
