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.
Solidity 0.8+ or Rust, leveraging battle-tested libraries like OpenZeppelin.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.
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.
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.
Implement flexible gas payment models, including paymaster integrations for sponsor-covered transactions. We optimize for cost efficiency with batched operations and gas estimation for privacy features.
Engineer secure, time-bound session keys that allow users to approve multiple transactions without repeated wallet prompts, while maintaining granular permission controls for enhanced security.
Architect and deploy your account abstraction stack across Ethereum, Polygon, Arbitrum, and other EVM-compatible chains. We ensure consistent user experience and contract interoperability.
Receive a custom TypeScript SDK and REST APIs for seamless integration of AA features into your frontend and backend, reducing development time from months to weeks.
Our account abstraction development delivers concrete, measurable improvements to your product's user experience, security, and operational efficiency. Here's what you can expect.
Replace seed phrases with social logins or passkeys. We implement ERC-4337-compliant smart accounts to onboard mainstream users in under 30 seconds, boosting conversion rates by up to 70%.
Deploy stealth addresses and privacy-preserving transaction bundlers. We architect systems where user activity is not trivially linkable on-chain, meeting stringent compliance needs for institutional clients.
Implement sponsored transactions and paymaster integrations. We abstract gas fees so your users never need to hold native tokens, removing a major barrier to adoption and enabling predictable operational costs.
Enable single-click approval for complex multi-step DeFi interactions. We build and audit custom UserOperation bundlers that execute atomically, reducing failed transaction rates and improving security.
Integrate social recovery, multi-signature guardians, and transaction limits directly into smart accounts. We provide battle-tested modules to drastically reduce support tickets related to lost access.
Deploy on high-throughput L2s like Arbitrum or Optimism with custom bundler and paymaster nodes. We ensure sub-second finality and 99.9% uptime for enterprise-grade reliability.

A structured, security-first approach to implementing privacy-preserving account abstraction. We deliver production-ready infrastructure with clear milestones and guaranteed outcomes.
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.
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.
We integrate and configure high-uptime bundler services (like Stackup, Alchemy, Biconomy) and deploy our managed relayer network to sponsor gas fees and ensure user operations are processed reliably.
We provide a tailored TypeScript SDK and integrate it with your dApp frontend (React/Next.js). This handles smart account creation, user operation signing, and seamless interaction with the privacy layer.
We conduct end-to-end testing on testnets (Sepolia, Holesky) including edge cases for social recovery and privacy leaks. We provide a full staging environment for your team to validate the user experience.
We manage the mainnet deployment and establish real-time monitoring for your AA system. We track key metrics: successful user ops, gas sponsorship costs, and relayer health to ensure operational excellence.
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.
