Proof-of-Account-Assets (PAA)
User Journey
Bob wants to access a premium DeFi lending protocol that requires proof of sufficient net worth for underwriting purposes. Using zkTLS, he securely connects to his traditional bank and brokerage accounts through an encrypted tunnel. The system verifies his total assets (cash, investments, securities) and liabilities (loans, credit balances) across multiple accounts, calculating key financial ratios without exposing specific transactions or account details. This Credential enables him to access tiered financial services across multiple platforms based on his verified financial position while maintaining complete privacy over his sensitive balance sheet data.

Why Verify Assets?
Asset verification serves as a fundamental pillar in sophisticated Anti-Money Laundering (AML) , financial crime prevention, and financial risk management frameworks. Financial institutions and DeFi platforms need to verify that users' declared wealth.
Why zkMe PAA
Traditional asset verification methods require users to submit comprehensive bank statements, investment portfolio details, and liability disclosures, creating massive privacy risks and potential attack vectors. zkMe's zkTLS-based asset verification transforms this process by enabling platforms to confirm the legitimacy of users' financial positions and wealth sources while ensuring that specific account balances, investment holdings, and liability details remain completely private. This approach meets enhanced due diligence requirements for high-value relationships while upholding the privacy principles essential to modern finance.
Comprehensive Financial Profiling: Unlike simple balance checks, our system analyzes complete financial positions across multiple institutions, calculating sophisticated metrics like net worth, leverage ratios, and liquidity profiles while maintaining full privacy through zero-knowledge proofs.
Multi-Account zkTLS Security: Our proprietary zkTLS technology creates secure tunnels to multiple financial institutions simultaneously, ensuring consolidated financial verification without ever aggregating raw data in a central location.
Advanced Risk Modeling: The protocol enables sophisticated underwriting based on verified financial ratios and patterns that are typically only available to traditional private banks and wealth managers.
Global Financial System Integration: Our system supports diverse financial institutions worldwide, adapting to different account types, currencies, and reporting standards while maintaining consistent privacy guarantees and verification reliability.
How It Works
The Proof-of-Account-Assets procedure uses zkTLS to create a secure, privacy-preserving bridge between traditional financial accounts and blockchain-based financial position verification.
Multi-Account Secure Connection
QR Code Generation: The zkMe widget generates a unique QR code for financial account linkage
Institution Selection: Users select from supported banks, brokerages, and financial institutions
Secure Authentication: Users log in directly to each financial institution through zkTLS secure tunnels
Data Scope Authorization: Users explicitly authorize what asset and liability data can be analyzed
Comprehensive Financial Analysis
Asset Verification: System cryptographically verifies cash balances, investment portfolios, securities holdings
Liability Assessment: Confirms outstanding loans, credit balances, and other financial obligations
Net Worth Calculation: Computes key metrics (debt-to-asset ratio, liquidity position, net worth brackets)
AML Compliance Screening: Asset sources and patterns are screened through zkAML integration
Data Minimization: Raw balance details and specific holdings are discarded after metric calculation
Zero-Knowledge Proof Generation
Commitment Phase: The user's device generates cryptographic commitments encoding financial ratios and thresholds
Challenge Phase: The verifier sends random challenges to ensure proof validity across multiple accounts
Response Generation: The user's device processes challenges with their aggregated financial data
Multi-Account Verification: Platform verifies consolidated financial position without accessing raw data from any single account
Credential Issuance & Financial Tiering
SBT Minting: A Proof-of-Account-Assets Soulbound Token is issued to the user's wallet
Financial Tier Assignment: The credential contains ZKPs of specific financial thresholds (e.g., "net worth > $100,000", "debt-to-asset ratio < 0.3")
Cross-Platform Reusability: The credential can be used across multiple DeFi protocols and financial services
