CORE ENGINEERING
Custom Smart Contract Development
Secure, audited smart contracts built for your specific business logic and compliance needs.
- Token Systems: Custom
ERC-20,ERC-721, andERC-1155implementations with advanced features like vesting, minting controls, and tax mechanics. - DeFi Protocols: Automated Market Makers (AMMs), lending/borrowing pools, staking systems, and yield aggregators.
- Enterprise Logic: Multi-signature wallets, DAO governance modules, and custom business logic for real-world asset (RWA) tokenization.
We deliver fully documented, upgradeable contracts with a clear handoff, enabling your team to own and iterate on the codebase long-term.

PROVEN PROCESS
Our Delivery Methodology
Our structured approach to decentralized identity portability ensures secure, compliant, and scalable solutions delivered on time. We focus on reducing your technical risk and accelerating your time-to-market.
01
Architecture & Protocol Selection
We design your identity stack based on W3C Verifiable Credentials, DID methods (did:ethr, did:key), and select optimal protocols (Polygon ID, OIDC4VC) for your specific use case and compliance needs.
2-3 days

Frequently Asked Questions
Get clear answers on how we deliver secure, interoperable identity state solutions for your Web3 application.
Our process follows a structured 4-phase methodology: 1) Discovery & Architecture (1-2 weeks): We analyze your use case, select optimal standards (W3C VC, OIDC, DID), and design the state model. 2) Development & Integration (3-6 weeks): Our team builds the smart contracts (Solidity/Cairo), issuer/verifier logic, and integrates with your frontend. 3) Security Audit & Testing (2 weeks): Mandatory internal audit followed by optional third-party review. 4) Deployment & Handoff (1 week): We deploy to mainnet/testnet, provide documentation, and conduct knowledge transfer.
