About

District Seal — a cryptographic evidence layer for high-stakes signatures. NEXSIM LLC is the parent company. I built District Seal to make signature disputes provably answerable. Every signing produces a court-admissible certificate: verified identity, spoken challenge, WebAuthn authentication, SHA-256 document seal. Zero biometric retention. GDPR/CCPA. US-hosted. Built for title companies, estate attorneys, brokers, lenders, and platforms via REST API. Self-taught. Learned to code by building this.

District Seal - The evidence layer for high-stakes signatures.

DocuSign proves an email clicked a link. District Seal proves the actual person was there. Every signing produces a court-admissible certificate: face match, randomized spoken challenge, hardware-backed device authentication, and a SHA-256 seal binding the identity to the exact document. Anyone can verify the record via a public QR code no account, no call to us required. Zero biometric retention. GDPR/CCPA. US-hosted. Built for title companies, estate attorneys, brokers, lenders, and platforms.
