ENTERPRISE-GRADE SECURITY & CONTROL
Core Capabilities of Our Institutional Wallets
Our account abstraction wallets are engineered for institutions requiring bank-level security, operational efficiency, and seamless integration with existing treasury workflows. We deliver a non-custodial foundation with the governance and compliance tools your team needs.
01
Multi-Party Computation (MPC) Security
Private keys are never stored in one place. Our MPC architecture distributes signing authority across multiple parties, eliminating single points of failure and enabling customizable approval policies (M-of-N) for transactions.

02
Programmable Transaction Policies
Define and enforce granular spending rules, velocity limits, and authorized recipient lists directly in the smart account. Automate compliance and reduce manual review for routine operations.

03
Gas Abstraction & Sponsorship
Remove UX friction for end-users and internal teams. Sponsor transaction fees or allow users to pay in any ERC-20 token. We handle gas estimation and optimization to reduce costs by up to 40%.
