Account Abstraction for Anonymity

We implement ERC-4337 and smart accounts to abstract stealth address key management, enabling seamless user onboarding and transaction batching for private operations.

overview
CORE SERVICE

Smart Contract Development

Secure, audited smart contracts built for production on any EVM or Solana chain.

We architect and deploy the foundational logic for your dApp. Our development process is built for security-first execution and long-term maintainability.

  • Production-Ready Code: Built with Solidity 0.8+ or Rust, leveraging battle-tested libraries like OpenZeppelin.
  • Multi-Chain Deployment: Seamless deployment to Ethereum, Arbitrum, Polygon, Base, Solana, and other leading L1/L2 networks.
  • Gas Optimization: Every line is written for efficiency, reducing user transaction costs by up to 40%.

We don't just write code; we engineer systems that hold and move value securely.

Our full-cycle service includes comprehensive unit and integration testing, formal verification where applicable, and a pre-audit review to ensure your contracts are audit-ready from day one. We deliver modular, well-documented code that your team can own and extend.

BUILT FOR PRIVACY

Core Technical Capabilities

Our infrastructure delivers production-ready, audited components for integrating privacy-preserving account abstraction into your application. We focus on security, developer experience, and seamless user onboarding.

01

Privacy-Preserving Smart Accounts

Deploy custom ERC-4337 smart accounts with built-in stealth address generation and transaction anonymization. We implement zero-knowledge proofs and ring signatures to decouple user identity from on-chain activity.

PROVEN METHODOLOGY

Our Development & Integration Process

A structured, security-first approach to implementing privacy-preserving account abstraction. We deliver production-ready infrastructure with clear milestones and guaranteed outcomes.

01

Architecture & Strategy Review

We analyze your current stack and user flows to design a custom AA architecture. We define the optimal mix of privacy primitives (ZK, stealth addresses, relayer networks) and select the most suitable bundler/paymaster providers.

Smart Contract Development & Audit

We develop your custom Account Factory, EntryPoint extensions, and recovery modules using Solidity 0.8+ with OpenZeppelin libraries. All contracts undergo a mandatory internal security review before deployment.

Frequently Asked Questions

Get clear, technical answers on implementing privacy-preserving smart accounts. Our team has deployed over 30 custom AA solutions for DeFi, gaming, and enterprise clients.

We architect privacy at the smart account layer using a multi-faceted approach. This includes deploying custom privacy modules for stealth transactions, integrating zero-knowledge proofs (zk-SNARKs via Circom) for selective disclosure, and leveraging privacy-focused bundlers to obscure transaction origin. We ensure on-chain activity is decoupled from user identity while maintaining full compliance with the underlying blockchain's security model.
