Wallets - 0xkey

  "walletId": "eb98ae4c-07eb-4117-9b2d-8a453c0e1e64",
  "walletName": "default"
}

Configuration

Wallet seeds are generated with a default mnemonic length of 12 words. The BIP-39 specification supports mnemonic lengths of 12, 15, 18, 21, and 24 words. To enhance your Wallet’s security, you may consider opting for a longer mnemonic length. This optional mnemonicLength field can be set when creating a Wallet. It’s important to note that once the Wallet seed is generated, the mnemonic is permanent and cannot be altered.

Accounts

An account contains the directions for deriving a cryptographic key pair and corresponding address from a Wallet. In practice, this looks like:

The Wallet seed and Account curve are used to create a root key pair
The Account path format and path are used to derive an extended key pair from the root key pair
The Account address format is used to derive the address from the extended public key

{
  "address": "0x7aAE6F67798D1Ea0b8bFB5b64231B2f12049DB5e",
  "addressFormat": "ADDRESS_FORMAT_ETHEREUM",
  "curve": "CURVE_SECP256K1",
  "path": "m/44'/60'/0'/0/0",
  "pathFormat": "PATH_FORMAT_BIP32",
  "walletId": "eb98ae4c-07eb-4117-9b2d-8a453c0e1e64"
}

The account address is used to sign with the underlying extended private key.

HD wallet default paths

HD wallets use standardized derivation paths to generate multiple accounts from a single seed. These paths follow a specific structure that allows for consistent address generation across different wallet implementations. Here are common default paths for some of the ecosystems supported by 0xkey:

Ethereum: m/44'/60'/0'/0/0
Cosmos: m/44'/118'/0'/0/0
Solana: m/44'/501'/0'/0'

For a complete list of coin types and possible HD paths, refer to the SLIP-0044 specification.

Where can I learn more?

In addition to the guide mentioned above on HD Wallets, there is also a page specifically on Derivation Paths.

What if I don’t see the address format for my network?

You can use ADDRESS_FORMAT_COMPRESSED to generate a public key which can be used to sign with (only sign raw payloads supported).

What is the difference between sign transaction and sign raw payload ?

SignRawPayload: network-agnostic, curve-based signing of messages. SignTransaction: network-specific transaction signing, including transaction parsing and compatibility with our policy engine.

What if I don’t see the curve for my network?

Delete wallets

To delete wallets you can call the delete wallets activity. Before deleting a wallet it must have been exported to prevent loss of funds, or you can pass in the deleteWithoutExport parameter with the value true to override this. The deleteWithoutExport parameter, if not passed in, is default false. Note that this activity must be initiated by the wallet owner.

Private keys

0xkey also supports raw private keys, but we recommend using Wallets since they offer several advantages:

Wallets can be used across various cryptographic curves
Wallets can generate millions of addresses for various digital assets
Wallets can be represented by a checksummed, mnemonic phrase making them easier to backup and recover

Export keys

Exporting on 0xkey enables you or your end users to export a copy of a Wallet or Private Key from our system at any time. While most 0xkey users opt to keep Wallets within 0xkey’s secure infrastructure, the export functionality means you are never locked into 0xkey, and gives you the freedom to design your own backup processes as you see fit. Check out our Export Wallet guide to allow your users to securely export their wallets.

Import keys

Importing on 0xkey enables you or your end users to import a Wallet or Private Key to our system. Check out our Import Wallet guide to allow your users to securely import their wallets.

Delete keys

To delete private keys you can call the delete private keys activity. Before deleting a private key it must have been exported to prevent loss of funds, or you can pass in the deleteWithoutExport parameter with the value true to override this. The deleteWithoutExport parameter, if not passed in, is default false. Note that this activity must be initiated by the private key owner.
