Hi, great looking library!

Are there plans to support Bryon master seed generation?

• https://input-output-hk.github.io/cardano-wallet/concepts/master-key-generation
• https://github.com/cardano-foundation/CIPs/blob/master/CIP-0003/Byron.md

And the same question for Ledger: https://github.com/cardano-foundation/CIPs/blob/master/CIP-0003/Ledger_BitBox02.md

This seems to be an issue with the latest release. After a transaction, calling the wallet's update method updates the transaction history of the wallet but the balance remains the same. It only changes after the app is restarted and/or wallet is rebuilt from keys again.

The assets property of the wallet class returns assets that were part of a transaction but not actually sent. An example would be sending 100 ADA from a wallet-A that has 2000 Hosky tokens to wallet-B that is empty(0 ADA, no assets). After the transaction, when you try checking the assets in wallet-B you find Hosky tokens. Although when you check the address on cardanoscan or pool.pm it shows just the ADA in wallet-B(which is how it should be).

The ada amount currently returned is an int(the coin class). What happens when a wallet has a balance of say 10.6 ada, how is that resolved?

Hi, how long are the cached wallets supposed to persist? I was thinking until they're cleared or if I uninstall the app but that's not the case. I lose all my cached wallets with every app restart.

Is there a way to send other native assets with ada?

Hi, i'm trying to restore a mainnet wallet but I keep getting this error
"The human readable part is mixed case, should either be all lower or all upper case: Ddz...."
The Ddz... looks like one of the addresses associated with this wallet.

When you create more than one wallet, all subsequent wallets created end up having the same Bip32SigningKey rootSigningKey as the first wallet.

After sending and receiving ADA, the next send transactions will fail with the following error message:

[ERROR:flutter/lib/ui/ui_dart_state.cc(209)] Unhandled Exception: Exception: 400: Bad Request: {"error":"Bad Request","message":"\"transaction submit error ShelleyTxValidationError ShelleyBasedEraAlonzo (ApplyTxError [UtxowFailure (WrappedShelleyEraFailure (MissingVKeyWitnessesUTXOW (WitHashes (fromList [KeyHash \\\"e33b0d3ff126938a6849b23e82e4f07c74fef5320f34d9acfc7044f3\\\"]))))])\"","status_code":400}

Hi when I build the wallet the whole app UI freezes. Can you fix the wallet build method so it will be async?

Good morning
please how do i use prepod as testnet with the api.

When I try sending a transaction, it throws, Error: submit cbor transaction: request is not validBad Request "transaction read error RawCborDecodeError"

Code:

var txResult = await wallet.sendAda(
toAddress: toAddress,
lovelace: ada * BigInt.from(3),
logTx: true,
logTxHex: true);
txResult.when(
ok: (tx) => prints(tx.hashHex),
err: (message) => print("Error: $message"),
);

The sync works ok for a while then throws this error Error: The human readable part is mixed case, should either be all lower or all upper case:.

Just curious as to how this works since based on my understanding this wallet is not running a node. Correct me if I'm wrong does this work by just serializing a TX, and then using blockfrost.io to do the heavylifting? Just wanted to know because I'm planning to use this as a personal tool to pass ADA around, I want to understand it deeper. Thanks for making this thing! :)

I love this initiative, just let me know if I could do anything to help. And I'm also curious if there's a group for Cardano developers building in Flutter.

how hard it should be to change it to support ethereum?

This library does not support signing transactions yet ?
I have read the implementation of the sendAda method:

@OverRide
Future<Result<RawTransaction, String>> sendAda(
{required ShelleyAddress toAddress, required int lovelaceAmount}) async {
if (lovelaceAmount > balance) {
return Err('insufficient balance');
}
if (toAddress.addressType != AddressType.Base) {
return Err('only base shelley addresses currently supported');
}
if (toAddress.hrp != 'addr' && toAddress.hrp != 'addr_test') {
return Err("not a valid shelley external addresses, expecting 'addr' or 'addr_test' prefix");
}
final builder = TransactionBuilder().send(shelleyAddress: toAddress, lovelace: lovelaceAmount);
//TODO calculate, fee, make change, sign and send
return Err('not yet implmented');
}

Hi there, the wallet transaction class has a currencies property that returns a map containing all the currencies in that transaction. The key of this map is a string which I believe is the asset id and its value is the quantity. How am I supposed to know what asset this actually is(ticker, actual name) using just this asset id provided?
