# Export keys

> Let a user export their raw private keys from a self-custody wallet.

A self-custody wallet can export its raw private keys. This is the user's escape hatch: their keys
are theirs, and they can take them elsewhere.

## Export

`exportEvmKey()` and `exportSolanaKey()` each run a passkey gesture and return the raw private key
as a hex string. They are available only on a self-custody (own-origin) client.

```ts theme={null}
const evmKey = await client.exportEvmKey();
const solanaKey = await client.exportSolanaKey();
```

In React, use `useExport`, which exposes both mutations with shared `pending` and `error`:

```tsx theme={null}
import { useExport } from "@avokjs/react";

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

<Info>
  The EVM key is the root; the Solana key is a leaf derived from it. Export returns raw keys, never a
  mnemonic phrase. Avok never mints one.
</Info>

<Warning>
  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.
