We architect, develop, and audit custom Solidity/Rust smart contracts that form the backbone of your protocol. Our focus is on security-first development, leveraging battle-tested patterns from OpenZeppelin and rigorous internal audits to mitigate risks before deployment.
Account Abstraction Smart Wallet Reputation Modules
Smart Contract Development
Secure, production-ready smart contracts built for scale and compliance.
- Custom Logic: Token standards (
ERC-20,ERC-721,ERC-1155), DeFi primitives, governance systems, and bespoke business logic. - Security & Audits: Multi-stage review process, formal verification readiness, and preparation for third-party audits from firms like
CertiKorQuantstamp. - Gas Optimization: Code engineered for efficiency, reducing user transaction costs by up to 40% through optimized storage and computation.
We deliver fully documented, upgradeable contracts with a clear roadmap for mainnet launch, typically within 4-6 weeks for an MVP.
Core Capabilities of Our Reputation Modules
Our modular reputation system provides the programmable trust layer for your smart wallets, enabling risk-aware transactions, automated compliance, and superior user experiences. Built for high-throughput applications.
Multi-Dimensional Risk Scoring
Real-time scoring based on on-chain history, transaction patterns, and Sybil resistance signals. Enables conditional logic for gas sponsorship, transaction limits, and access control.
Custom Rule Engine
Define and deploy bespoke reputation logic without smart contract redeploys. Supports complex conditions (e.g., allow if score > X AND tx value < Y) via a secure admin interface.
Sybil Attack Mitigation
Proprietary algorithms detect and penalize coordinated wallet clusters, protecting your dApp from airdrop farming, governance attacks, and spam. Integrates with proof-of-personhood layers.
Gas Abstraction Policies
Automate paymaster decisions using reputation scores. Sponsor gas for trusted users, require partial payment for neutral actors, and block high-risk wallets—all configurable by you.
Portable Reputation Graph
User reputation is a portable, verifiable asset. Scores and history can be permissionlessly queried by other dApps, creating a cross-application trust network that benefits legitimate users.
Business Outcomes: Reduce Risk, Scale Operations
Our Account Abstraction Reputation Modules deliver measurable infrastructure improvements, enabling your team to focus on product innovation while we manage the critical security and scalability layer.
Proactive Risk Mitigation
Real-time reputation scoring and automated transaction screening to flag and block malicious activity before execution. Reduces fraud losses and protects user assets with zero manual intervention.
Gasless User Onboarding
Deploy ERC-4337 compliant Paymasters to sponsor user transactions. Eliminate the friction of acquiring native tokens, increasing user activation rates and enabling true mass-market adoption.
Enterprise-Grade Uptime
Fully managed, multi-cloud infrastructure with automated failover and 24/7 monitoring. Our reputation oracles and bundler relays are built for high-throughput DeFi and gaming applications.
Compliance-Ready Operations
Configurable transaction policies and detailed audit logs for every user session and sponsored operation. Simplify regulatory reporting and internal security reviews with immutable, chain-verified data.
Rapid Integration & Scalability
Pre-built SDKs and APIs for seamless integration with existing wallets and dApps. Scale from prototype to production with modular reputation models that adapt to your user base growth.
Cost-Optimized Sponsorship
Dynamic Paymaster strategies that optimize for gas prices and subsidy models. Reduce your operational costs with batch transactions and intelligent fee market analysis.
