Ethereum and Starknet Keys

Ethereum (L1) private key is used to sign a message. Generated signature is deterministic and can only be generated by the owner of the Ethereum private key.

This signature is then used to generate Starknet (L2) private key (also referred to as Paradex private key).

Starknet (L2) private key can be used to deduce Starknet public key. L2 private key is also used to generate auth, onboarding and order signatures.

Auth endpoint also requires providing the Ethereum address which is derived from the Ethereum private key in examples of some languages.

During the onboarding process, an Account Contract is deployed on Starknet with the Starknet public key. This account contract address is used to identify token and perpetual balances on chain.

On UI, after connecting with your Ethereum wallet, you will be able to click on the truncated L2 address (top right) and view your L1 and L2 address. As well as copy the L2 private key to clipboard.

To get complete understanding of this, please refer to Onboarding & Wallets section in Paradex documentation.

Ethereum and Starknet Keys
Ethereum (L1) private key is used to sign a message. Generated signature is
deterministic and can only be generated by the owner of the Ethereum private key.
This signature is then used to generate Starknet (L2) private key
(also referred to as Paradex private key).
Starknet (L2) private key can be used to deduce Starknet public key.
L2 private key is also used to generate auth, onboarding and order signatures.
Auth endpoint also requires providing the Ethereum address which is derived
from the Ethereum private key in examples of some languages.
During the onboarding process, an Account Contract is deployed on Starknet
with the Starknet public key. This account contract address is used to identify
token and perpetual balances on chain.
On UI, after connecting with your Ethereum wallet, you will be able to click on
the truncated L2 address (top right) and view your L1 and L2 address. As well as copy the
L2 private key to clipboard.
To get complete understanding of this, please refer to Onboarding & Wallets section in Paradex documentation.
