Function: detectionKeyFor()

function detectionKeyFor(
   P, 
   vk, 
   gamma?
): FmdDetectionKey;

Defined in: @lelantos-org/sdk/dist/keys/keys.d.ts:68

The γ FMD detection scalars for a viewing key, as POST /v1/subscriptions expects them via detectionKeyToHex. One key detects for every address of the account.

Releasing these releases the root detection secret permanently: h_i is public, so any single x_i yields dk = x_i - h_i.

gamma is capped at FMD_DEFAULT_GAMMA, not GAMMA_MAX: a longer key tests clue bits senders never set and discards the wallet's own notes.
