Identity Aggregation SDK Creation

We build custom SDKs and developer tools that abstract the complexity of aggregating identity data from multiple chains and protocols, enabling rapid integration of unified profiles into any dApp.

overview
SECURE FOUNDATIONS

Custom Smart Contract Development

Build production-grade smart contracts with formal verification and battle-tested security patterns.

We architect and deploy secure, gas-optimized smart contracts for DeFi, NFTs, and enterprise protocols. Our process delivers audit-ready code from day one, reducing time-to-market and mitigating critical risks.

  • Security-First Development: Built on Solidity 0.8+ with OpenZeppelin libraries and custom security modules.
  • Formal Verification: Key logic is mathematically verified using tools like Certora to eliminate entire classes of bugs.
  • Gas Optimization: Every function is profiled to minimize transaction costs, crucial for high-volume dApps.

We don't just write code; we engineer systems that protect your assets and your reputation.

Our deliverables include comprehensive technical specifications, deployment scripts for testnets and mainnets, and developer documentation. We specialize in complex primitives like automated market makers (AMMs), vesting schedules, and multi-signature governance systems.

PROVEN PROCESS

Our Delivery Methodology

We deliver production-ready identity SDKs through a structured, transparent process designed for technical founders and engineering teams. Each phase is built on our experience with protocols like ENS, OAuth, and decentralized identifiers.

01

Architecture & Protocol Design

We architect your SDK's core identity layer, selecting and integrating the optimal protocols (ENS, OAuth, SIWE, Verifiable Credentials) for your use case. This phase defines the data flow, privacy model, and on/off-chain components.

2-4 weeks

CORE INFRASTRUCTURE

Smart Contract Development

Secure, production-ready smart contracts built for scale and compliance.

We architect and deploy custom smart contracts that form the backbone of your Web3 application. Our development process is built on security-first principles, utilizing audited libraries like OpenZeppelin and rigorous testing frameworks to ensure reliability and protect user assets.

From tokenization to complex DeFi logic, we deliver contracts that are gas-optimized, upgradeable, and ready for mainnet.

Our typical deliverables include:

  • Token Contracts: Custom ERC-20, ERC-721, and ERC-1155 implementations with minting, vesting, and governance features.
  • DeFi & DEX Modules: Automated Market Makers (AMMs), liquidity pools, staking, and yield farming mechanisms.
  • Security & Compliance: Integration with Chainlink oracles, multi-signature wallets, and compliance hooks for regulatory requirements.
  • Full Audit Support: Code prepared for third-party audits with comprehensive documentation and test coverage exceeding 95%.

We move from concept to deployed contract in 2-4 weeks for an MVP, providing you with a verifiable, on-chain foundation that scales with your business.
