# Mnemonic

An essential aspect of regulatory compliance of our Blockchain as a service infrastructure is to keep wallets non-custodial. Users are interacting with their very own keys and we only store those fragments that enable them to unlock them for transaction processing purposes.

#### Mnemonic Phrase

As a non-custodial wallet, users are responsible for backing up their keys. The mnemonic phrase function returns the 12 word backup seed-phrase of the wallet selected. 

```javascript
var parameters = {
    serviceId: 'optional',
    walletID: 'optional',
}
const response = await relysia.wallet.v1.mnemonic(parameters);
```

The mnemonic phrase secures your wallet keys. Each mnemonic acts as seed of a HDPrivatekey that itself contains hundrets of PrivateKeys.

### Retrieve Funds

The mnemonic phrase is the seed for a HDPrivateKey with millions of potential addresses. You can extract your funds from the **M/44/0/0/{1,2,3...}** path. First transactions will always go to the first addresses and their corresponding private keys, while over time, to prevent address re-usage for privacy reasons we use a larger and larger address space. Nonetheless, knowing the order of writings, you can recover all funds without Relysia.&#x20;
