We ensure your foundation is robust, providing:
We architect and deploy the complete technical stack for your on-chain reputation system, from secure smart contracts to a scalable frontend. Each component is built for production, ensuring data integrity, user trust, and seamless integration.
Custom smart contracts for minting, updating, and verifying soulbound reputation tokens (ERC-721S). Implements Sybil-resistance, multi-attestation logic, and configurable decay mechanisms.
A secure framework for issuing verifiable credentials and attestations. Supports EIP-712 signatures, multi-sig governance for issuers, and on-chain proof verification.
High-performance indexer and GraphQL/REST API that aggregates reputation scores across chains and protocols. Delivers real-time, queryable data to your dApp frontend.
A comprehensive dashboard for platform operators to manage issuers, monitor system health, audit attestations, and visualize reputation score distributions and trends.
A responsive, wallet-integrated frontend (React/Next.js) where users can view their reputation profile, manage attestations, and see their standing within the ecosystem.
Full smart contract audit report from industry-leading firms, comprehensive test suite with >95% coverage, and ongoing monitoring for vulnerabilities and anomalous activity.
Our full-stack reputation dApp development delivers measurable compliance outcomes, reducing manual overhead and integrating seamlessly with your existing risk framework.
Integrate programmable KYC/AML checks directly into user onboarding flows. We build with verified identity protocols (e.g., Polygon ID, Verite) to reduce manual review by 80% and ensure regulatory adherence from day one.
Deploy a custom reputation engine that scores wallet activity for risk (sanctions, mixers, illicit patterns). Receive instant alerts for high-risk transactions to meet FinCEN Travel Rule and global AML standards.
Generate regulator-ready compliance reports from an immutable on-chain log. Our systems automate the creation of audit trails for every user action and transaction, slashing reporting preparation time.
A configurable smart contract module that enforces jurisdiction-specific rules (e.g., geofencing, investor accreditation). Update logic without full redeployment, ensuring agility as regulations evolve.

A structured, security-first approach that delivers production-ready reputation systems with embedded compliance, ensuring faster time-to-market and reduced technical risk.
We design modular, upgradeable reputation logic using Solidity 0.8+ with OpenZeppelin libraries. Our focus is on gas efficiency, clear data structures, and secure access control from day one.
Every reputation contract undergoes multi-stage review, from automated analysis with Slither to manual audits by our senior engineers. Critical logic is formally verified for high-assurance systems.
We build responsive, intuitive dApp interfaces with React/Next.js and provide TypeScript SDKs for seamless integration of reputation queries and updates into your existing applications.
We architect reputation systems with compliance hooks for data privacy (GDPR/CCPA), Sybil resistance, and regulatory reporting, avoiding costly post-launch refactors.
Comprehensive test suites using Foundry/Hardhat with >95% branch coverage. We simulate mainnet conditions and edge cases to ensure system reliability before deployment.
Managed deployment to your chosen EVM chain with verified source code. We set up real-time monitoring dashboards for on-chain metrics, alerts, and performance tracking.

Answers to common technical and commercial questions about building a custom on-chain reputation system.
A complete MVP with core reputation logic, token-gating, and a basic frontend typically deploys in 4-6 weeks. Complex systems with custom Sybil resistance, multi-chain logic, or advanced analytics dashboards can take 8-12 weeks. We provide a detailed sprint-by-sprint roadmap after the initial discovery phase.
