StarkNet & zkSync Account Abstraction Wallets

Implement gasless transactions and flexible fee sponsorship models. We build paymasters that allow you to cover user fees, accept payments in any ERC-20 token, or enable subscription-based models, removing the primary UX barrier for mainstream adoption.

Deploy secure multi-sig wallets with customizable approval thresholds and social recovery mechanisms. We implement guardian frameworks and time-locked recovery flows, ensuring user asset security without sacrificing accessibility.

Enable seamless user experiences with session keys for pre-authorized actions and atomic transaction batching. Users can approve multiple operations in one signature, essential for complex DeFi interactions and gaming applications.

Custom account contracts built with StarkNet's Cairo or zkSync's Solidity/Vyper, following OpenZeppelin and official protocol standards. Includes upgradeability patterns, role-based access control, and event logging for full observability.

Integrate native bridging capabilities for asset and message passing between Ethereum L1, StarkNet, zkSync Era, and other L2s. We implement canonical bridges and third-party liquidity solutions for a unified multi-chain wallet experience.

Every wallet module undergoes rigorous security review. We partner with leading audit firms for external assessments and employ formal verification tools for critical state transitions, delivering a foundation you can trust for high-value applications.

We begin with a technical deep-dive to design a modular wallet architecture tailored to your use case—be it DeFi, gaming, or enterprise custody. We define the core components: the Account contract, Paymaster strategy, and bundler integration.

Implementation in Cairo 1.0 (StarkNet) or Solidity with Yul (zkSync) using battle-tested patterns. We focus on gas efficiency, upgradability via proxies, and seamless integration with native AA infrastructure.

Every line of code undergoes internal review followed by a formal audit from a leading Web3 security firm. We provide a detailed vulnerability report and implement all recommendations before deployment.

Rigorous testing on StarkNet Goerli and zkSync Sepolia. We simulate real-world attack vectors, high-load scenarios, and fee market fluctuations to ensure resilience and optimal user experience.

Managed deployment with multi-sig governance. We provide 24/7 monitoring for transaction success rates, paymaster subsidy costs, and security alerts, ensuring immediate incident response.

Complete technical documentation, admin guides, and integration SDKs for your engineering team. We ensure a smooth knowledge transfer for long-term maintenance and feature development.
