BUILT FOR PRODUCTION
Core Architecture of Your Attestation Network
We deliver a complete, modular architecture for on-chain attestations, designed for security, scalability, and seamless integration. Each component is built to enterprise standards.
01
On-Chain Registry & Schema Management
Deploy a custom, gas-optimized registry contract (EIP-4804/ERC-3668 compatible) to define and manage attestation schemas. Supports complex data types, revocation logic, and permissioned issuers.

Decentralized Attestation Network FAQs
Get clear answers on timelines, costs, and technical implementation for your on-chain reputation and verification system.
A production-ready attestation network with core features (issuer onboarding, schema management, on-chain verification) typically deploys in 3-5 weeks. Complex integrations (multi-chain support, custom privacy layers, advanced revocation) can extend this to 6-8 weeks. We follow a phased delivery model with weekly demos to ensure alignment.
