Frequently Asked Questions
Your question not answered here?
Embedded wallets are created and managed inside your app rather than through a separate browser extension. With Openfort, keys are split and managed via a secure signer (OpenSigner) and smart wallet contracts, so users never see seed phrases but still get non-custodial control. Your app talks to Openfort’s APIs/SDK, which orchestrate wallet creation, session keys, and transaction signing for you.
Browser extension wallets (like MetaMask) live outside your app and require context-switching, pop-ups, and manual connection flows. Embedded wallets live inside your product: users sign up with email or social login and immediately have a wallet ready to use. Openfort also lets you link both worlds—embedded wallets plus external EOAs—so power users can connect an existing wallet while everyone else gets a seamless embedded experience.
Session keys let you pre-authorize a limited set of actions for a limited time (e.g. “up to X transactions, for this game, on this chain”). Instead of signing every single move or purchase, the user approves a session once and the app spends from that session key within strict policies. Openfort exposes session keys through account abstraction (EIP-4337 / EIP-7702) so you can tune limits, expiration, and scopes to your risk model.
With account abstraction, you can sponsor gas for users using a Paymaster so they don’t need native tokens just to move assets. Openfort’s Paymaster handles gas sponsorship and can be combined with embedded wallets so users just see “send 10 USDC,” not “approve ETH for gas.” That’s especially useful for stablecoin payments, gaming microtransactions, and consumer apps where on-chain UX needs to feel like a normal fintech app.
They can be—and Openfort is built to be non-custodial by default. Keys are generated client-side and split into shares; recovery is tied to your login and policies rather than seed phrases. Because OpenSigner is self-hostable, you can migrate infra or providers later without forcing users to change wallets, giving you embedded wallet UX without long-term vendor lock-in.
