## Notes
1. <a name="ETHPublicKey"></a> This should probably be `44'/60'/a'`, but unfortunately MyEtherWallet sends `44'/60'/a'/0`. So for backwards compatibility we allow both options. trezor.wallet.io sends `44'/60'/a'/0` for MEW compatibility.
2. <a name="Ripple"></a> Although Ripple does not have the concept of change, it uses secp256k and has normal derivation defined. For interoperability reasons we use `44'/144'/a'/0/i`.
3. <a name="Stellar"></a> Defined by Stellar themselves in their [SEP-0005](https://github.com/stellar/stellar-protocol/blob/master/ecosystem/sep-0005.md).
4. <a name="Cardano"></a> Which allows normal derivation on ed25519.
5. <a name="NEM"></a> NEM's path should probably be `44'/60'/a'`, but due to historical reasons this is set to `44'/60'/a'/0'/0'`.
6. <a name="Monero"></a> Actually it is GetWatchKey for Monero.
7. <a name="BitcoinDiagram"></a> With some exceptions. The following diagram shows a path should be validated for Bitcoin-like coins:
