A bill of exchange can function as "legal tender" or "tender of payment," but its status depends on acceptance and context but regardless, if tendered correctly, it does discharge the debt and respective amount tendered. It is a written instrument where one party (the drawer) orders another (the drawee) to pay a specific amount to a third party (the payee). While bills of exchange can be negotiable, they can also be non-negotiable, meaning they don’t always transfer ownership upon indorsement.
