Module chain_path_derivation::bip44

Bip44 derivation scheme

based on the [BIP-0044] scheme.

While nearly only the full bip44 address is indeed interesting, it is valuable to keep the different intermediate steps as they can be reused to define specific API objects.

For example, for example a wallet with support to multiple coin types will be interested to keep the m/'44 path. For every account it is interesting to keep the m/'44/'<coin_type>/'<account>.

We have the 5 levels of Derivations: m / purpose' / coin_type' / account' / change / address_index

Examples

basic usage:

use chain_path_derivation::bip44;

let account = bip44::new().bip44().coin_type(BITCOIN).account(ACCOUNT_01);
assert_eq!(account.to_string(), "m/'44/'0/'0")

then it is possible to generate addresses from there:

let change = account.external();
let first_address = change.address(SoftDerivation::min_value().wrapping_add(0));
let second_address = change.address(SoftDerivation::min_value().wrapping_add(1));
assert_eq!(first_address.to_string(), "m/'44/'0/'0/0/0");
assert_eq!(second_address.to_string(), "m/'44/'0/'0/0/1");
