Addresses issue: #1406

Thanks @shonsirsha, we will look into that

btw, I got a question for bitbox02 devs, if you are in touch with them - will bitbox firmware support vote delegation certificates? Shortly (not sure when exactly, no exact times available, AFAIK) after the upcoming hardfork, in order to be able to withdraw rewards, wallets will need to delegate their vote at least to an "always abstrain" DRep - more info here:

Relevant fields in the transaction body: https://github.com/IntersectMBO/cardano-ledger/blob/cf05d70ea4e8eae4ce2ad349ed17850c0c8204d1/eras/conway/test-suite/cddl-files/conway.cddl#L277 https://github.com/IntersectMBO/cardano-ledger/blob/cf05d70ea4e8eae4ce2ad349ed17850c0c8204d1/eras/conway/test-suite/cddl-files/conway.cddl#L303

We didn't update Adalite yet, but will do so in the upcoming weeks

Hi @refi93, BitBox firmware dev here. If it is required to withdraw staking funds, we will support it. Any suggestions for how to test such a change before it is live?

Would you potentially be interested in helping us to add support in the BitBox02 firmware? It could be more efficient as you will be more familiar with the details. There is a simulator for easy testing.

called from the main transaction verification/processing function:

@benma For the sake of inspiration/test vectors I'd recommend checking the ledger JS library integration tests which include also transactions with vote delegations and other new kinds of certificates: https://github.com/vacuumlabs/ledgerjs-cardano-shelley/blob/9c643c406ed200e44b56e8349ec2ac3c53b670de/test/integration/__fixtures__/signTx.ts#L758

here's Ledger's cardano app source code: https://github.com/LedgerHQ/app-cardano/blob/605d7095d9d40cc04b18cb398a163d50e0215afd/src/signTx.c#L1101

additionally, here's trezor firmware PR adding conway functionality: https://github.com/trezor/trezor-firmware/pull/3496/files

regarding possible assistance with development, we'll discuss internally and get back to you in the upcoming 1-2 days 👍
