use privatekey to sign trans

[xbcq]

hi,the java lib can not sign using derived key using bip39 or bip32? So in java lib,how to use private key and send the amount ,

@xbcq It's possible. You have to get private and public keys for address
Then:

K256KeyPair ecPair = new K256KeyPair(new BigInteger(privateKey, 16), new BigInteger(publicKey, 16))

// sign transaction
SignedTransaction signed = payment.sign(ecPair)
