PROVEN PROCESS
Our Delivery Methodology
Our systematic approach to legal document attestation ensures regulatory compliance, technical accuracy, and seamless integration with your existing workflows.
01
Compliance & Framework Analysis
We begin with a deep analysis of your target jurisdictions and document types to map all regulatory requirements. Our team identifies the specific attestation protocols (e.g., eIDAS, UNCITRAL Model Law) and blockchain standards required for legal validity.

Standards Supported
02
Smart Contract & Notary Design
We architect and develop the core attestation logic as audited, immutable smart contracts. This includes timestamping, hash anchoring to public ledgers (Ethereum, Solana), and creating verifiable proof-of-existence records that meet legal evidence standards.

Integration & API Deployment
We deploy a secure, scalable API layer that integrates directly with your document management systems (DMS) or application backend. Our RESTful APIs handle document submission, status tracking, and proof retrieval without disrupting your operations.

Verification Portal & Audit Trail
We deliver a white-labeled verification portal for third parties to independently validate document authenticity. Every attestation creates a permanent, tamper-proof audit trail with cryptographic proof, accessible via QR code or unique verification ID.
