value = 5M USD We’ve changed the variable names for programming style, but see how these properties map almost directly to the issue method variables. The issue method is automatically given control by contract transaction, locate the buy and redeem transaction definitions, and see if you can see how they map to their corresponding commercial paper transactions. The buy transaction: Txn = buy Issuer = MagnetoCorp containing a public key, a private key, and some Fabric- specific metadata. Different wallet types map this structure appropriately to their storage mechanism. A Fabric wallet can hold multiple identities
