Hi all,
Is it possible to generate publickey from private key? Usually, in other blockchains I have seen this feature.
The account system is based on ED25519.
With SDK, you could generate keypair, try this:https://ae-labs.herokuapp.com/
@LiuYang.chain what I meant was, given the privatekey to the sdk, can we generate public key? by the way, I developed the ae laboratory
Happy that you have gone through it and linked here 
I can not remember that there are such functions in golang or python SDK.
We might have to do the ED25519 calculating by ourselves 
do you know if they have in js sdk? @YaniUnchained any idea?
Hey @nduchak.chain @marco.chain Can you provide some information here, please?
@vishwas_hypermine you are able to create it. But you have to NOT use HD wallets, because you will get different public key each time. I have to dig for the code, but you can check the sdk docs. I was using the js-sdk.

Hey, you can import this method from like:
import { getAddressFromPriv } from '@aeternity/aepp-sdk/es/utils/keystore
@nduchak.chain Perfect! this worked thanks!
Now with this I will be able to reduce one field (publickey) from the laboratory.
@martingrigorov.chain In ECDSA, given the privatekey point § and base point G, the public key (pk) can be calculated using formula, (pk) = §*G. so there must be a function in library which should return the publickey key, given the private key as input, theoretically.
