Institutional Identity Attestation Development | Chainscore Labs

overview

CORE INFRASTRUCTURE

Smart Contract Development

Secure, audited smart contracts built to your exact specifications, from concept to deployment.

We architect and deploy production-ready smart contracts that power your Web3 application. Our development process ensures security-first design, gas optimization, and full audit readiness from day one.

Custom Logic: Build on Solidity 0.8+, Rust (Solana), or Vyper for DeFi, NFTs, DAOs, and more.
Security Framework: Integrated testing with Foundry/Hardhat and adherence to OpenZeppelin standards.
Deployment & Verification: Full mainnet deployment support with automated verification on Etherscan/Solscan.

Move from specification to a secure, live contract in as little as 2-4 weeks for an MVP.

We handle the entire lifecycle:

Architecture Review: Design patterns for upgradability and access control.
Comprehensive Testing: Unit, integration, and scenario-based tests.
Gas Profiling: Optimization to reduce user transaction costs by 20-40% on average.
Audit Preparation: Code structured and documented for seamless third-party audit handoff.

Institutional Identity Attestation

Frequently Asked Questions

Get clear answers on how we build secure, compliant identity solutions for your institution.

A standard institutional identity attestation system is typically deployed in 4-6 weeks. This includes design, core smart contract development, integration with your existing KYC/AML stack, and initial testing. Complex multi-jurisdictional requirements or custom on-chain reputation systems can extend this to 8-10 weeks. We provide a detailed project plan within the first week of engagement.
