Export keys - Avok

A self-custody wallet can export its raw private key. This is the user’s escape hatch: the key is theirs, and they can take it elsewhere.

Export

exportEvmKey() runs a passkey gesture and returns the raw private key as a hex string. It is available only on a self-custody (own-origin) client.

const evmKey = await client.exportEvmKey();

In React, use useExport:

import { useExport } from "@avokjs/react";

function Export() {
  const { exportEvmKey, pending, error } = useExport();
  // Call inside a user gesture; it triggers a passkey prompt.
}

K is the EVM key, so this one key is the whole wallet. Export returns the raw key, never a mnemonic phrase. Avok never mints one.

An exported key is plaintext custody. Once it leaves the passkey sandbox, Avok’s guarantees no longer apply to that copy. Handle it in a user gesture, show it once, and never persist or transmit it.
