Hi Community,

i want to register my pool with metadata with created payment+stake keys as Operator and Hw-Wallet as Owner.

i followed this guide for instructions:

> **[Cardano Stake Pool Owners HW Support](https://adalite.medium.com/cardano-stake-pool-owners-hw-support-6d9278dba0ba)**
>
> Protect pool owner’s pledge with Ledger or Trezor.

issue1) alonzo era is not supported yet, so i had to add --mary-era in tx build → OK!  
issue2) when i now want to sign with the provided witness.json (from [adalite.io](http://adalite.io)) i get an era-error.

```auto

```

```auto
cardano-cli transaction build-raw \
    --tx-in <tx>#0 \
    --mary-era \
    --tx-out $(cat payment.addr)+0 \
    --invalid-hereafter 0 \

    --certificate-file pool-registration.cert

```

    --fee 202417 \
    --out-file tx.raw \
    --certificate-file pool-registration.cert

```

```auto

    --signing-key-file payment.skey \
    --signing-key-file stake.skey \
    --signing-key-file witness.json \
    --signing-key-file cold.skey \
    --mainnet \
    --out-file tx.signed

```

Command failed: transaction sign Error: Error reading signing key: **witness.json** : TextEnvelope type error: Expected one of: PaymentSigningKeyByron\_ed25519\_bip32, PaymentSigningKeyShelley\_ed25519, PaymentExtendedSigningKeyShelley\_ed25519\_bip32, StakeSigningKeyShelley\_ed25519, StakeExtendedSigningKeyShelley\_ed25519\_bip32, StakePoolSigningKey\_ed25519, GenesisSigningKey\_ed25519, GenesisExtendedSigningKey\_ed25519\_bip32, GenesisDelegateSigningKey\_ed25519, GenesisDelegateExtendedSigningKey\_ed25519\_bip32, GenesisUTxOSigningKey\_ed25519 **Actual: TxWitness MaryEra**

i know it’s a sign/assemble topic but i cannot figure out, how to get my .skeys + witness files along in one signed transaction to submit.

I think this last command isn’t correct. You should “assemble” the transaction with the witness, not sign it

So instead of this

```auto
cardano-cli transaction sign \
    --tx-body-file tx.raw \
    --signing-key-file payment.skey \
    --signing-key-file stake.skey \
    --signing-key-file witness.json \
    --signing-key-file cold.skey \
    --mainnet \
    --out-file tx.signed

```

It should be something like this:

```auto
cardano-cli transaction assemble \
--tx-body-file tx.raw \
--witness-file operator.witness \
--witness-file pool.witness \
--witness-file owner.witness \
--out-file tx.signed

```

so you need to produce the respective witnesses for the other signing keys (stake.skey, payment.skey, cold.skey) using the `cardano-cli shelley transaction witness` command

These instructions can be found in the docs linked from the blog article: [cardano-hw-cli/poolRegistration.md at develop · vacuumlabs/cardano-hw-cli · GitHub](https://github.com/vacuumlabs/cardano-hw-cli/blob/develop/docs/poolRegistration.md#create-signed-transaction)
