The desk's Strike Finance API wallet - generating an Ed25519 keypair, registering the public key, the request signing scheme (method, path, timestamp, nonce, body hash), the signed-request helper every authenticated call goes through, what the key can and cannot do, and rotation. Use when connecting the desk to a Strike account, when any authenticated call returns 401, or when a key is rotated. Read this before strike-account and strike-orders.
