CORE SERVICE
Smart Contract Development
Secure, production-ready smart contracts built by Web3 specialists.
We write contracts that handle real value. Security is not an afterthought.
- Full Lifecycle Development: From specification and
Solidity/Rustcoding to deployment and verification onEtherscan/Solscan. - Security-First Architecture: Built with
OpenZeppelinstandards, comprehensive unit/integration testing, and formal verification for critical logic. - Gas Optimization: Expert-level tuning to reduce user transaction costs by 15-40% without compromising security.
Our engineers have deployed over 200+ contracts managing >$50M in TVL. We provide the technical foundation so you can focus on product growth and user acquisition.

ARCHITECTURE
Core Components of Our Reputation Systems
We build modular, secure, and scalable reputation infrastructure designed for high-throughput Web3 applications. Each component is engineered for performance and interoperability.
03
Customizable Scoring Algorithms
Tailored reputation models with weighted scoring for lending risk, governance power, or community contribution. Algorithms are transparent, auditable, and adjustable via governance.

Drive Platform Growth with On-Chain Reputation
Move beyond basic wallet connections. Our reputation systems provide verifiable, portable identity layers that unlock higher-value interactions, reduce platform risk, and create powerful growth loops for your application.
01
Custom Reputation Logic & Scoring
We design and deploy on-chain reputation models tailored to your platform's needs—whether it's for DeFi lending tiers, DAO governance weight, or NFT community access. Implement scoring based on transaction history, social attestations, or staking activity.

TRANSPARENT & ITERATIVE
Our Development Process
We deliver production-ready decentralized reputation systems through a structured, collaborative process designed for technical founders. Each phase is built on verifiable security and measurable outcomes.
01
Architecture & Protocol Design
We architect your reputation system's core logic, tokenomics, and data models. This includes selecting the optimal on-chain/off-chain data storage, defining Sybil-resistance mechanisms, and designing the incentive structure.

Frequently Asked Questions
Get clear answers on our development process, timelines, security, and support for building on-chain reputation protocols.
We deliver a production-ready MVP in 4-6 weeks for a standard on-chain reputation protocol. This includes core smart contracts, a basic frontend, and integration with your existing dApp. Complex systems with custom sybil resistance, multi-chain logic, or advanced governance can extend to 8-12 weeks. We provide a detailed project plan with milestones after the initial discovery phase.
