Hardware management of ephemeral session keys, automated recurring subscriptions, and institutional multi-signature custody.
WalletHSM manages ephemeral session keys that allow dApps to execute transactions without requiring user confirmation for every interaction. The hardware module strictly enforces parameter scopes (e.g. max 50 USDC per day, approved smart contracts only).
For corporate treasuries using Safe (Gnosis Safe), WalletHSM serves as an authoritative hardware signer that validates transaction calldata against internal treasury policies before appending its cryptographic signature.
