Is there a way to do this programmatically? I have an

Address ShelleyAddr

obtained from

deserialiseFromBech32 AsShelleyAddress

and need its

Plutus.V1.Ledger.Crypto.PubKeyHash

There is now the function shelleyPayAddrToPlutusPubKHash in cardano-api which returns Maybe PubKeyHash because in the case of a script credential there is no corresponding public key hash.

  • I cannot find shelleyPayAddrToPlutusPubKHash. How exactly do I import it?

  • In cabal.project, what tag hash do I use for source-repository-package type: git location: https://github.com/input-output-hk/cardano-node.git ?

This compiles with a recent version of cardano-node and plutus:

import Plutus.V1.Ledger.Api (PubKeyHash)
import Cardano.Ledger.Alonzo.TxInfo (transKeyHash)
import Cardano.Api (ShelleyAddr)
import Cardano.Api.Shelley (Address (ShelleyAddress))   
import Cardano.Ledger.Shelley.API (Credential (KeyHashObj, ScriptHashObj))

                                                                                             
addrToPkh :: Address ShelleyAddr -> PubKeyHash
addrToPkh (ShelleyAddress net (ScriptHashObj sh) sr) = transKeyHash sh
addrToPkh (ShelleyAddress net (KeyHashObj kh) sr) = transKeyHash kh

  • Is there such a thing as an AlonzoAddr (via deserialiseFromBech32 AsAlonzoAddress)? I am only using ShellyAddr because that's what I found in the API.

  • cabal build is giving me: unknown package: cardano-ledger-shelley. Not sure what to do.

  • @Kwaggy: AlonzoAddr is fine and to make it compile you need to add cardano-ledger-shelley to your code's .cabal file in the build-depends section and maybe ensure you are having the https://github.com/input-output-hk/cardano-ledger-specs as a source-repository-package in cabal.project (depends a bit on your workflow).

  • @insitu: For recent version of cardano-node, I downloaded pre-compiled executable from docs.cardano.org/getting-started/installing-the-cardano-node and parked the unzipped in my root dir. How do I teach cabal about it, such that .cabal file is happy with having cardano-ledger-shelley in its build-depends section?
