Function: computeSpendIntentDigest()

computeSpendIntentDigest(context): bigint

Defined in: src/tx/witness.ts:71

Recompute the spend-auth digest (message) from an intent context — poseidon([merkleRoot, boundParamsHash, ...nullifiers, ...commitmentsOut]). A SpendSigner implementation calls this and asserts it equals the message it was asked to sign, so a compromised host cannot pair a benign context with a malicious digest (SPEC §4.2.1). CctpBinding type re-exported for signer authors.

Parameters

context

SpendIntentContext

Returns

bigint
