Account Abstraction Smart Wallet Reputation Modules

Chainscore develops custom ERC-4337-compatible smart account modules that enforce transaction rules based on verifiable on-chain reputation, automating compliance and reducing manual review.

overview
CORE SERVICE

Smart Contract Development

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

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.

  • 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 CertiK or Quantstamp.
  • 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.

ENGINEERED FOR SCALE AND SECURITY

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.

01

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.

02

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.
