For address derivation, you may. try: in walletconsole:

• coin ada
• newkey
• pubpri #
• addrpub # Result: Ae2tdPwUPEZ7n97UGCpGkDYuPW7HG7zFwxELZwvtyAE8L8Ypii5L94GdGyR
• setMnemonic cost dash dress stove morning robust group affair stomach vacant route volume yellow salute laugh
• addrDefault Result: Ae2tdPwUPEZ6RUCnjGHFqi59k5WZLiv3HoCCNGCW8SYc5H9srdTzn1bec4W

You can try this in adalite also:

• https://adalite.io/

To test tx creation:

• Create new Cardano address (rec. phrase, derived prikey, addr)
• Send some ADA to it
• check address&txs on https://cardanoexplorer.com
• put together new transaction, sign it with Signer -- see Cardano/SignerTests.cpp.
• push result to node, like this:

curl -d '{"txHash":"ebf58670ee1512d597876fe632e92790bd70568374bdbe5a69c5d8ed107607ee","txBody":"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"}' -H "Content-Type: application/json" https://adalite.io/api/txs/submit

A note on multi-input transactions:

• The transaction data contains signatures. It has to have the same number of signatures as input UTXOs, and in the same order. The private key of signature N must match the address of UTXO N.
• In the SigningInput to WalletCore CardanoSigner the order does not matter. Signer will take each UTXO (in shuffled order), find its matching private key, and create a signature with it.
• If there are multiple UTXOs with the same address, in the SigningInput is enough to add the private key once. Signer will create exactly N signatures, in the right order, if needed using a private key more than once.
• The UTXOs specified has to contain the address as well. This is needed to be able to match UTXOs with private keys. For a wallet, it should be no problem to provide this info, as address summary includes addresses along UTXOs.
