Core Features of Our Attestation System
Our platform delivers the technical foundation for verifiable, portable credentials. We handle the complex infrastructure so your team can focus on building user-centric applications.
On-Chain & Off-Chain Verification
Enable instant verification of credentials both on-chain for smart contract logic and off-chain for user-facing applications. Our verifier libraries support multiple signature schemes for maximum flexibility.
Revocation & Lifecycle Management
Maintain full control over credential validity with secure, gas-efficient revocation registries. Update or revoke attestations without compromising user privacy or on-chain efficiency.
Multi-Chain & L2 Agnostic
Deploy your attestation logic on Ethereum, Polygon, Arbitrum, Optimism, or Base. Our system abstracts chain complexity, providing a unified interface for credential issuance and verification.
Enterprise Security & Compliance
Built with security-first principles. Our infrastructure undergoes regular audits, supports role-based access control (RBAC), and provides audit trails for all issuance and revocation events.
Business Outcomes for Your Platform
Our on-chain credential attestation service delivers measurable value, from accelerating user onboarding to unlocking new revenue streams. Here's what you can expect.
Accelerated User Onboarding
Reduce KYC/AML verification from days to seconds with automated, reusable credential checks. Integrate with existing identity providers for a seamless user experience.
Enhanced Platform Security & Compliance
Leverage tamper-proof, cryptographically verifiable credentials to meet regulatory requirements (e.g., Travel Rule, MiCA). Built-in fraud detection and audit trails.
New Monetization & Loyalty Models
Create gated experiences, token-gated communities, and dynamic loyalty programs based on verifiable user attributes and achievements.
Reduced Operational Overhead
Eliminate manual verification processes and central credential databases. Our service handles issuance, revocation, and verification logic, cutting your compliance costs.
Developer Velocity & Scalability
Integrate with our production-ready APIs and SDKs in days, not months. Scale to millions of verifications with our managed infrastructure.

Our Delivery Process: From Audit to Integration
A structured, four-phase methodology designed for technical leaders. We deliver production-ready on-chain credential systems with clear milestones, guaranteed SLAs, and zero surprises.
Phase 1: Architecture & Smart Contract Audit
We begin with a deep technical review of your existing credential logic and data models. Our team delivers a security-first architecture blueprint and a comprehensive smart contract audit report, identifying vulnerabilities before a single line of new code is written.
Deliverables: Threat model, gas optimization analysis, and audit findings report.
Phase 2: Custom Contract Development
Our engineers build your attestation logic using battle-tested patterns (ERC-5568, EIP-712). We implement custom credential schemas, revocation registries, and verifier contracts with a focus on gas efficiency and upgradability via transparent proxies.
Deliverables: Production-ready Solidity/Vyper contracts, deployment scripts, and comprehensive unit/integration tests.
Phase 3: Security Verification & Formal Audit
All contracts undergo rigorous internal verification followed by a formal audit from our partner security firms. We provide a verifiable audit certificate and remediate any findings, ensuring your system meets enterprise-grade security standards before mainnet deployment.
Deliverables: Formal audit report, certificate of compliance, and remediation proof.
Phase 4: Deployment & Integration Support
We handle the complete deployment process across your chosen networks (EVM, L2s, Solana) and provide direct integration support for your engineering team. This includes SDKs, API documentation, and monitoring dashboards for real-time attestation analytics.
Deliverables: Live production deployment, integration SDKs, and 24/7 monitoring setup.
Smart Contract Development
Secure, production-ready smart contracts built by certified auditors for your Web3 application.
We architect and deploy custom smart contracts on EVM and Solana that form the secure backbone of your application. Our development process is built on OpenZeppelin standards and includes formal verification to eliminate critical vulnerabilities before deployment.
From tokenomics to complex DeFi logic, we translate your business rules into immutable, gas-efficient code.
- End-to-End Development: Full lifecycle from architecture and
Solidity/Rustcoding to testing and mainnet deployment. - Security-First Approach: Every contract undergoes manual review and automated analysis with tools like Slither and MythX.
- Gas Optimization: We minimize transaction costs, achieving up to 40% gas savings on complex operations.
- Post-Deployment Support: Includes upgradeability planning using
Transparent ProxyorUUPSpatterns and monitoring.
Frequently Asked Questions
Get clear answers on how our attestation service works, from integration to security and ongoing support.
On-chain credential attestation is the process of issuing, verifying, and managing verifiable credentials (like KYC status, certifications, or membership) on a blockchain. You need it to build trustless, automated systems for identity, access control, and compliance. Our service replaces manual verification with cryptographic proofs, enabling features like permissioned DeFi, gated NFT drops, and compliant token launches without centralized bottlenecks.
