Core Features of Our Embedded Wallet Contracts
Our modular smart contract suite provides the foundational security, flexibility, and performance required to power seamless user onboarding and transaction flows for your dApp.
01
Non-Custodial Security Architecture
Users retain full control of their assets with private keys secured by MPC (Multi-Party Computation) or Account Abstraction (ERC-4337). We implement battle-tested OpenZeppelin libraries and undergo regular third-party audits.

Business Outcomes: Why Embed a Smart Wallet
Embedded wallets are not just a technical feature; they are a strategic growth lever. Here's how integrating a smart wallet directly into your dApp delivers measurable business results.
01
Accelerate User Onboarding
Eliminate the friction of seed phrases and external wallets. Users sign up with familiar Web2 methods (email/social) and are transacting in under 60 seconds, converting more visitors into active users.
< 60 sec

70%+
Onboarding Completion
02
Boost User Retention & Engagement
Keep users in your app's flow. No more disruptive wallet pop-ups or context switching. Seamless, in-app transactions lead to higher session duration and repeat usage.

Frequently Asked Questions on Embedded Wallets
Get clear answers on implementation, security, costs, and timelines for integrating a seamless, non-custodial wallet experience into your dApp.
A standard integration for a single dApp takes 2-4 weeks from kickoff to production deployment. This includes smart contract deployment, SDK integration, and security review. Complex multi-chain deployments or custom social login flows may extend the timeline, which we scope and agree upon before project start.
