A derivation path is a string representing a sequence of key derivations from the root key used to create different addresses and accounts.

Below are the common derivation paths using a modified SLIP44-type scheme that generates BIP-32 keys.

Derivation Path Format

The standard derivation path format is as follows:

m/purpose/coin_type/account/change/address

Each part of the path represents

• m: Master node.
• purpose: Set to 44 (unhardened) for BIP-44.
• coin_type: SLIP44 identifier for the coin.
• account: The account number. Index begins at 0.
• change: 0 for external addresses, 1 for change addresses (not used currently).
• address: The address. Index begins at 0.

Example Commands

When recovering master key shares from an ERS backup, you can specify the derivation path in your commands. Here are examples for macOS and Linux:

macOS

Replace {the derivation path} with the appropriate path.

./coldwallet-cli-darwin ers  
  --backup-file-path={Where you store the backup file}  
  --private-key-pem-path={the private key path}  
  --derivation-path={the derivation path}

Linux

Replace {the derivation path} with the appropriate path.

./coldwallet-cli-linux ers  
  --backup-file-path={Where you store the backup file}  
  --private-key-pem-path={the private key path}  
  --derivation-path={the derivation path}
