Sendin asset error

Question

I have created a keypairs and imported the wallet without priv key, is there a way to allow this address send assets without importing with privkey or is there a way to dump the private key again?

Answer 1

You can still import the private key if you like, using importprivkey, and it will effectively "upgrade" the address in the wallet from a watch-only address to an owned address.

Alternatively you can build and sign transactions for this address without ever importing the private key into the wallet – please see this tutorial: https://www.multichain.com/developers/external-key-management/
