What we build for you
ERC-4337 wallets & Bundler integration
We build Account Abstraction wallets that don’t require ETH on the balance. Use EntryPoint contracts, Bundler services, and Paymaster integration to cover gas fees in any token.
Modular architecture & plugins
Custom modules such as spending limits, multisig, sessions, subscriptions, and rule-based actions. Flexible logic without rewriting the entire wallet.
Authentication & security
Support for WebAuthn, biometrics, email login, and multi-factor authentication. Role-based access, address whitelists/blacklists, and seedless recovery mechanisms.
dApp & Web3 integration
Compatibility with any Web3 application via WalletConnect and custom SDKs. Seamless integration with DeFi, NFT, and DAO platforms.
Frictionless UX flows
One-click transactions, reduced confirmations, sponsored transactions, and fully customized user flows tailored to your product.
Multi-network support
Ethereum, Arbitrum, Optimism, Polygon, zkSync, and other L2 and EVM-compatible networks. Infrastructure ready for mass adoption and scaling.
Launch a wallet from scratch
We deliver smart accounts with zero entry barriers and frictionless UX.
