Services we provide

4 Layers

Wallet

Spin up secure wallets in-flow. Keys aren’t a single secret: they’re MPC/threshold shares (e.g., 2-of-3) with one on the device, one with a key service, and a recovery share tied to social factors (email/phone) or a guardian wallet (e.g., MetaMask). No seed phrase, fast restore, user control by default.

Orchestration

You set who gets paid and how much. We enforce it every time. Only approved destinations can receive funds (approved list) Caps to prevent too many or too-large payouts (limits) Alerts when something looks unusual (automatic fraud checks) Each order is processed once, with reliable event logs.

Execution

We run the payment in one go according to your rules and cover network fees for the user (paymaster). We simulate first, cap fees, and fall back safely if the network is busy. No custom smart-contract build or audit needed for wallet logic.
