ENTERPRISE-GRADE INFRASTRUCTURE
Core Features of Our Smart Account Factory
Our Smart Account Factory is built for production, delivering the modularity, security, and developer experience required to launch and scale next-generation Web3 applications.
02
Gas Abstraction & Sponsorship
Enable gasless transactions for your users with built-in paymaster integration. We configure flexible sponsorship models, including ERC-20 fee payment and batched transactions to reduce costs by up to 40%.
03
Multi-Chain Deployment Kit
Launch your smart account system across any EVM chain. Our factory includes pre-configured deployment scripts and verification tooling for Ethereum, Polygon, Arbitrum, Base, and other L2s.
04
Security-First Development
Every module is built with OpenZeppelin libraries and undergoes rigorous internal review. We provide a comprehensive audit-ready codebase, following best practices for access control and reentrancy protection.
05
Social Login & Key Management
Integrate familiar Web2 onboarding with social logins (Google, GitHub) via MPC or embedded wallets. We implement secure session keys and account recovery flows to eliminate seed phrase friction.
06
Batch Transaction Engine
Bundle multiple user operations into a single transaction. Our optimized bundler service reduces latency and gas costs, enabling complex DeFi interactions or NFT mints in one click.
