Secp256k1 Private Key

The getPrivateKey method returns the user's secp256k1 private key (the elliptic curve used by Ethereum and EVM-compatible chains). Use this key to sign transactions on EVM-compatible chains.

When you set useSFAKey to true in Web3AuthOptions, this method returns the single-factor authentication (SFA) key instead of the standard private key.

Usage​

let privateKey = web3Auth.getPrivateKey()
