@exodus/key-ids

This package holds key identifiers for Exodus' own BIP43 purpose that cater for different use cases to deterministically derive key pairs from the seed.

Exodus Purpose Field

Exodus has its own bip43 purpose field for internal use.

This module exports this purpose value as the number 6649967, which is equivalent to the UTF-8 encoded text exo.

Documented Usage Paths

The bip32 paths currently used are listed here along with their descriptions. ' denotes hardened derivation. Note that hardened derivation is always used for the Exodus Purpose.

Path	Usage
m/EXO'/1'/0	Wallet info file deterministic encryption key
m/EXO'/1'/1	Public key is used for backing up the info file
m/EXO'/2'/0'	Keypair used for e2e libsodium ed25519 keys
m/EXO'/2'/2'	Deprecate, do not re-use this path for anything
m/EXO'/2'/3'	Keypair used to binauth with telemetry server
m/EXO'/3'/0'	Keys used to sign mesages for the Wallet of Satoshi APIs
m/EXO'/4'/1'	Used for signing & encrypting messages w.r.t username client
m/EXO'/5'/n'	The last number n is reserved for seedless project, 0 is used for seedless backup id
m/EXO'/6'/0'	Key used to derive auth key for fiat server
m/EXO'/7'/0'	Encryption key for encrypting extra seeds in a multi-seed wallet

Jan 15 2019 - Konnor Klashinsky:

• Moved the EXODUS_PURPOSE constant from #/exodus-purpose to #/bip43-purpose so the module can be used for other BIP43 purpose constants like SegWit.

Feb 24 2019 - Konnor Klashinsky:

• Added the SEGWIT_NESTED_PURPOSE constants for P2WPKH-nested-in-P2SH, used for hardware wallets

Mar 1 2019 - Konnor Klashinsky

• Added the HD_WALLET_PURPOSE constants for BIP44 HD wallets.

July 3 2019 - Max Ogden

• Added 1 path used for libsodium ed25519 derivation using SLIP-0010 in the e2e syncing implementation.

July 4 2019 - Konnor Klashinsky:

• Moved #/bip43-purpose to #/constants/bip43.

Dec 17, 2019 - Mark Vayngrib:

• Added m/EXO'/2'/1' path used to derive mnemonic encryption key in 2fa mode (encrypts mnemonic stored on mobile)

Dec 31, 2019 - Mark Vayngrib:

• Added m/EXO'/2'/2' path used to derive encryption key for twofactor.seco

Jan 28, 2020 - Mark Vayngrib:

• Removed m/EXO'/2'/2' path used to derive encryption key for twofactor.seco, will use randombytes instead

Feb 7, 2020 - Mark Vayngrib:

• Removed m/EXO'/0'/0 path used to derive the no longer used Exchange EID

Jul 12 2021 - Vlad Stan

• Added m/EXO'/3'/0' path used to derive the keys used to sign messages for the Wallet of Satoshi REST APIs.
• Each account will derive a path according to its index: m/EXO'/3'/0'/0', m/EXO'/3'/0'/1', etc

May 02 2022 - Florian Mathieu

• Added m/EXO'/2'/2' path as deprecated to prevent re-use in the future
• Added m/EXO'/2'/3' path as keypair for telemetry binauth

Mar 23, 2023 - Guten Ye

• Added m/EXO'/5'/n' path used for seedless project

Nov 13, 2023 - Diego Muracciole

• Remove unused m/EXO'/2'/1' path used for 2fa mnemonic encryption

February 28th, 2024 - Mark Vayngrib

• Added m/EXO'/6'/0' path for key used to derive auth key for fiat server
• Added m/EXO'/7'/0' path used for deriving the encryption key used for encrypting extra seeds in a multi-seed wallet
