Is there any way to create the neutered extended key by the public key?

[thomas-tran]

Hi,

From the extended key we can get the private and public key in buffer and convert it to hex. Is there anyway that we can recreate the neutered extended key from either private key or public key hex?

The issue if some one send me the hash message, the signature and provide the public key. I need to verify it. In order to create the account, the Wallet only accept the extended key.

Hello, following should be of help, please don't hesitate if any more question:

const key = new NodeEd25519(
            undefined, // privateKey (D part)
            this.publicKey, // publicKey (Q part)
            this.chainCode,
            Network.CATAPULT,
            0, // depth
            0, // index
            0x00000000, // parentFingerprint
        );

using the above you can then instantiate a neutered extended key: new ExtendedKey(key, Network.CATAPULT)

Hi evias,

Assume I only got the public key in hex. What's the chaincode? How can I construct the NodeEd25519 without knowing the chaincode ?

Another question is can the wallet holds multiple account or 1 wallet only had 1 account?
