tsn-exit API

Source-derived exports, parameter and result types, public methods and source links.

This reference is generated from the checked-out TypeScript exports. Types and signatures describe the package contract; source presence does not establish deployment or service availability. Error expressions below are direct throws, not an exhaustive list of failures from dependencies.

decodeExitDebitInstructionData

Decode the exact TSN debit instruction emitted by tsn_register_tcap_exit_debit_v1.

This is a pure decoder. It does not decrypt the sealed TIP, derive a TIN, or authorize a payout. The Node must combine this evidence with its authenticated sealed-head and TIN commitment readers before creating any cross-chain authorization.
