CORE ENGINEERING
Smart Contract Development
Secure, audited smart contracts built for production by senior Solidity engineers.
- Security-First Architecture: Built with
OpenZeppelinlibraries and custom security patterns, followed by third-party audits from firms like CertiK or Quantstamp. - Full-Stack Integration: Contracts are delivered with comprehensive test suites, deployment scripts, and frontend SDKs (
ethers.js/viem) for seamless integration. - Protocol Specialization: Custom
ERC-20,ERC-721, staking pools, automated market makers (AMMs), and cross-chain bridges.
We guarantee zero critical vulnerabilities in audit reports and provide post-deployment monitoring via our
Chainscoreplatform.

Technical & Commercial Questions
Credential Interoperability Consulting: FAQs
Answers to common questions about our consulting process, timelines, and the value we deliver for Web3 identity and credential systems.
Our process follows a structured 4-phase methodology: 1) Discovery & Audit (1 week): We analyze your current identity stack, target ecosystems, and compliance requirements. 2) Architecture Design (1-2 weeks): We deliver a technical spec for your cross-chain credential system, including protocol selection (e.g., Verifiable Credentials, EIP-712, IBC). 3) Implementation & Integration (2-4 weeks): Our engineers build and integrate the interoperability layer with your dApp. 4) Testing & Deployment (1 week): We conduct security reviews and assist with mainnet deployment. This ensures a predictable, transparent path to launch.
