wallet_createSignature

Creates a digital signature using wallet keys. Supply exactly one of data or hashToDirectlySign.

Result

The BRC-100 createSignature result, encoded as JSON text. Wallet failures return an error result.

Permissions

Forwarded to the connected wallet under the configured app origin. Its protocol, certificate or basket permission checks apply to the requested operation.

In role-routed configurations, walletRole selects an assigned wallet. Identity methods default to the identity role; encryption and HMAC use the encryption role. Transaction and basket operations follow their assigned role. An unavailable role fails rather than borrowing another key.
