We architect and deploy custom Solidity and Rust smart contracts that are secure by design. Every contract undergoes formal verification, automated testing, and third-party audits from firms like CertiK or OpenZeppelin before deployment to mainnet.

Cross-Chain Identity Oracle Integration
We build secure bridges between off-chain identity data and on-chain applications. Integrate decentralized oracle networks to verify and synchronize user credentials (KYC, social proofs, reputational data) across Ethereum, Solana, Polygon, and other L2s for a unified, portable identity state.

PROVEN FRAMEWORK
Our Integration Methodology
A structured, security-first approach to deploying cross-chain identity oracles that ensures reliability and accelerates your time-to-market.
01
Architecture & Design Review
We analyze your existing stack and design a modular oracle architecture using standards like CCIP, LayerZero, or Axelar. This ensures seamless integration with your smart contracts and off-chain systems.

Frequently Asked Questions
Get clear answers on timelines, security, and process for integrating a custom identity oracle into your multi-chain application.
A standard integration project takes 4-6 weeks from kickoff to mainnet deployment. This includes 1 week for design and architecture, 2-3 weeks for core development and unit testing, 1 week for internal security review, and 1 week for deployment and final integration testing. Complex requirements like custom attestation logic or support for 5+ chains can extend the timeline.
