BIP-44 Derivation Paths

Coin Curve GetPublicKey GetAddress SignTx Derivation Note
Bitcoin secp256k1 m/p'/c'/a' m/p'/c'/a'/h/i m/p'/c'/a'/h/i BIP-32 1
Ethereum secp256k1 m/44'/60'/0' m/44'/60'/a'/0/0 m/44'/60'/a'/0/0 BIP-32 2
Cosmos secp256k1 m/44'/118'/0' m/44'/118'/a'/0/0 m/44'/118'/a'/0/0 BIP-32 -

Where p is the BIP-44 purpose described further in 1.

Where c is the Coin's slip44 id.

Where a is the Account index, starting from 0.

Where h is 0 / 1 for External / Change respectively (for UTXO coins).

Where i is the address index, starting from 0.

Notes

  1. For Bitcoin and its derivatives, p is decided based on:

    p Type Input Script Type
    44 Legacy SPENDADDRESS
    48 Multisig SPENDMULTISIG
    49 p2sh SegWit SPENDP2SHWITNESS
    84 Native SegWit SPENDWITNESS

Other p are strongly discouraged with an on-device warning. c must be equal to the coin's slip44-id.

  1. For legacy reasons, Ethereum address derivation paths are very non-standardized across vendors. Not much we can do about it unfortunately, since there are lots of wallets out in the wild with funds on them at those addresses.

Allowed Values

For SignTx on UTXO coins, i must be in the range [0, 1000000].
