How to use `Address` instead of `ByronAddress` as witness

@faustbrian Why did you stike-through your text? What solution did you find?

I still cannot find a method to convert the result of privateKey.to_bech32() back to a PrivateKey. The generating transactions example also shows the use of CardanoWasm.PrivateKey.from_bech32 which is undefined...

The code you showed converts from a BIP39 seed and not a bech32 private key like ed25519e_sk16rl5f..., so I'm confused.

Shelley addresses (usually BaseAddress witnesses are created using make_vkey_witness (

cardano-serialization-lib/rust/src/utils.rs

Line 530 in 15d193f

pub fn make_vkey_witness(

)

And yes, all of Shelley (and every other hardfork) is supported.

You can find example code here (but this example code hasn't been updated for Mary yet) https://github.com/Emurgo/cardano-serialization-lib/blob/59426b43d105e6cf4f05e4b5945c0cb3dc483130/doc/getting-started/generating-transactions.md#example-code

Feel free to re-open the issue if you think this doesn't address your question.

Thanks, that got me a bit further but the CardanoWasm.PrivateKey.from_bech32 method doesn't seem to exist anymore which is used in const prvKey = CardanoWasm.PrivateKey.from_bech32("ed25519e_sk16rl5fqqf4mg27syjzjrq8h3vq44jnnv52mvyzdttldszjj7a64xtmjwgjtfy25lu0xmv40306lj9pcqpa6slry9eh3mtlqvfjz93vuq0grl80");.

What has this been replaced with? I assume with from_normal_bytes and from_extended_bytes and the Bech32 private key should be turned into an UInt[] or are there any helper methods to turn the private key into bytes?

const privateKey = CardanoWasm.Bip32PrivateKey.from_bip39_entropy(Buffer.from(BIP39.toEntropy(mnemonic), "hex"), Buffer.from(""))
		.derive(harden(Purpose.CIP1852))
		.derive(harden(slip44))
		.derive(harden(0))
		.to_raw_key();

@CherryDT our solution is here https://github.com/ArkEcosystem/platform-sdk/blob/master/packages/platform-sdk-ada/src/services/transaction.ts#L26-L136

@faustbrian Thank you but I'm a bit lost, I see here only handling of derived keys. Can you point me to the exact place you are loading a string starting with ed25519e_ into a CardanoWasm.PrivateKey object?

@CherryDT there is no method to get a PrivateKey struct from a bech32 string, you will need the raw bytes and then you can use from_extended_bytes() or from_normal_bytes(), depending on how you generated that private key.
