What is BIP32?

Address path (BIP32) defines how to derive private and public keys of a wallet from a binary master seed (m) and an ordered set of indices.

BIP32 derivation path:
 
m / 0' / 0' /k'

BIP32 extended private key represents the extended private key derived from the derivation path. An example of a BIP32 extended private key is:

Trezor and BIP32 address paths

Trezor uses BIP44, which is based on BIP32. BIP44 dictates the derivation path:
 
  m / purpose' / coin_type' / account' / change / address_index


Overview of standard derivation paths of recovery seeds know by the latest Trezor firmware 

Cryptocurrencies

BIP44-like paths (discoverable):
 

  • m/44'/cointype'/account'/change/address ... BIP44 P2PKH
  • m/49'/cointype'/account'/change/address ... BIP49 P2WPKH-nested-in-P2SH
  • m/84'/cointype'/account'/change/address ... BIP84 P2WPKH

BIP44-like paths (non-discoverable):
 
  • m/48'/cointype'/account'/change/address ... multisig P2SH, implemented in Copay wallet, no BIP or SLIP defined

Others:
 
  • m/48'/network'/role'/account'/key' ... SLIP48 Graphene-based blockchains

Custom cryptography
 
  • m/13'/A'/B'/C'/D' ... SLIP13 Sign in with Trezor
  • m/17'/A'/B'/C'/D' ... SLIP17 ECDH
  • m/10015'/0' ... SLIP15 Trezor Wallet labeling metadata
  • m/10016'/0 ... SLIP16 Trezor Password Manager metadata
