Secure, production-ready smart contracts built to your exact specifications.
We architect and deploy custom smart contracts for ERC-20, ERC-721, and complex ERC-1155 standards. Our code is built on Solidity 0.8+ with OpenZeppelin libraries, ensuring security from the first line.
We deliver battle-tested contracts with a 100% clean audit record from leading security firms.
Key Deliverables:
Hardhat or Foundry frameworks.For CTOs & Technical Leads:
Our notarization platform is built on a foundation of immutable blockchain protocols and rigorous security standards, delivering verifiable proof and operational resilience for your critical documents.
Our blockchain-based notarization delivers concrete, verifiable business advantages. Move beyond theoretical benefits to measurable operational improvements.
Anchor document hashes to public blockchains like Ethereum or Solana, creating a timestamped, cryptographically verifiable proof that cannot be altered or backdated. Eliminates disputes over document origin and timeline.
Meet regulatory requirements for data integrity and audit trails (e.g., GDPR, SEC Rule 17a-4). Automate compliance workflows with verifiable, court-admissible evidence, reducing manual review time and legal overhead.
Replace expensive, manual notary services and centralized timestamping authorities with automated, API-driven blockchain proofs. Drastically lower per-document costs and eliminate vendor lock-in.
Provide customers and partners with transparent, self-verifiable proof of your document handling. Builds trust in digital processes and strengthens your brand's reputation for security and transparency.
Deploy with our production-ready APIs and SDKs in days, not months. Includes comprehensive documentation, code samples for Solidity and Rust, and dedicated technical support for seamless integration.

A streamlined, security-first methodology designed to integrate blockchain notarization into your workflows with minimal disruption and maximum legal defensibility.
We analyze your document workflows and data models to design a custom on-chain schema. This phase defines the proof format (Merkle root, timestamp, signature) and selects the optimal blockchain (Ethereum, Polygon, Solana) for your cost, speed, and permanence requirements.
Our team develops and deploys the core notarization smart contract. We implement industry standards like EIP-712 for structured data signing and integrate with decentralized timestamping oracles (e.g., Chainlink) to anchor proofs with verifiable, tamper-proof timestamps.
We provide a production-ready REST API and client SDKs (Node.js, Python, Go) for seamless integration. Your team can notarize documents and verify proofs with simple API calls, abstracting away blockchain complexity. Includes comprehensive documentation and code samples.
Every contract undergoes a rigorous security audit following our internal checklist, with optional third-party audits from firms like CertiK or Quantstamp. We ensure compliance with data privacy regulations (GDPR) by implementing hash-only storage and providing data redaction tools.
We deploy the complete system to a staging environment matching your production specs. We conduct load testing to validate performance under peak transaction volumes, ensuring sub-second notarization and verification times at scale.
We manage the mainnet deployment and provide ongoing monitoring, alerting, and maintenance. Includes a 99.9% uptime SLA for our API gateway and proactive support for upgrades (e.g., Ethereum hard forks). You receive a complete verification portal for end-users.
Secure, production-ready smart contracts built for scale and compliance.
We architect and deploy audited, gas-optimized contracts on EVM chains (Ethereum, Polygon, Arbitrum) and Solana. Our process ensures your core business logic is secure and efficient from day one.

Traditional notarization relies on a trusted third-party authority and paper-based records, which can be slow, costly, and vulnerable to loss or forgery. Our service uses public blockchains (like Ethereum, Polygon, and Solana) to create an immutable, cryptographic proof of a document's existence and integrity at a specific point in time. This proof is globally verifiable, tamper-proof, and does not require a centralized authority, reducing costs and increasing trust and auditability.
