StarkNet Cairo Account Abstraction for Shared Accounts

We develop and audit modular, upgradeable smart accounts in Cairo with configurable multi-signature policies, role-based permissions, and batch transaction execution for seamless team operations.

Implement gasless transaction flows and paymaster integrations, allowing end-users to interact with your dApp without holding ETH. We handle the complex sponsorship logic and fee management.

Every shared account system undergoes rigorous internal review and optional third-party audits. We employ formal verification tools for Cairo to mathematically prove critical contract properties.

Full-stack deployment of your account abstraction layer, including indexers, relayers for gas sponsorship, and monitoring dashboards for tracking account activity and gas expenditure.

Engineer secure session key systems that allow pre-authorized transactions within defined limits (time, value, contracts), enabling seamless UX for repetitive dApp interactions.

Build robust account recovery mechanisms, including social recovery with guardian sets and customizable delay periods, ensuring user assets are never permanently locked.

Deploy multi-signature or role-based shared accounts with custom approval flows, enabling secure treasury management, DAO operations, and institutional custody on StarkNet.

Implement gasless transactions and fee delegation models. Remove onboarding friction for end-users by allowing apps or third parties to sponsor transaction costs.

Leverage battle-tested OpenZeppelin Cairo libraries and undergo rigorous security audits for your custom account logic, mitigating risks in high-value shared account systems.

Bundle multiple user operations into a single L2 transaction. Dramatically reduce per-operation costs and improve the user experience for complex DeFi interactions.

Replace complex seed phrases with social logins or embedded non-custodial wallets. Drastically improve conversion rates by abstracting blockchain complexity.

Deploy with upgradeable account logic using proxy patterns. Add new signers, change security rules, or integrate new protocols without migrating user assets.

We build with the latest Cairo 1.0, leveraging its enhanced safety features and developer experience for secure, efficient, and maintainable account abstraction logic.

Implement multi-signature, social recovery, and gas sponsorship for shared accounts using native StarkNet AA and ERC-4337-compatible entry points for cross-chain interoperability.

Every contract undergoes rigorous audits following OpenZeppelin patterns and formal verification principles specific to Cairo, ensuring mathematical proof of correctness for core logic.

Architect efficient storage patterns for shared account state, managing permissions, transaction queues, and nonce handling to minimize L2 storage costs and maximize throughput.

Build secure messaging bridges and withdrawal flows, enabling your shared accounts to interact seamlessly with assets and contracts on both Ethereum Mainnet and StarkNet.

We provide full deployment pipelines, automated testing on testnets (Sepolia/Goerli), and real-time monitoring dashboards for account activity and system health.
