I'm working on a Plutus contract that requires multiple signatures to unlock. To do so, I've been referencing the MultiSig.hs sample contract. Now, I'm looking to create traces for testing purposes, however, these tests are commented out in Spec.hs with the comment "disable temporarily, because we need to adopt the signing API," but I'm not really sure what this means.
Is it currently possible to sign a transaction with multiple Wallets or PubKeyHash's? If so, how?
