Governance examples (Ogmios + Kupo, SanchoNet, Eternl Beta & KeyWallet):

• Gov.ManageDrep
  • Covered certificates:
  • RegDrepCert
  • UpdateDrepCert
  • UnregDrepCert
• Gov.ManageDrepScript
• Gov.DelegateVoteAbstain
  • Covered certificates:
  • VoteRegDelegCert
• Gov.SubmitVote
• Gov.SubmitVoteScript

New CIP-95 functions exported from Contract.Wallet:

• ownDrepPubKey
• ownDrepPubKeyHash
• ownRegisteredPubStakeKeys
• ownUnregisteredPubStakeKeys

NOTE: KeyWallet does not distinguish between registered and unregistered stake keys due to the limitations of the underlying query layer. This means that all controlled stake keys are returned as part of ownUnregisteredPubStakeKeys, and the response of ownRegisteredPubStakeKeys is always an empty array.
