Simple Summary

This aexpansion specify the derivation path used in the Aeternity blockchain for

Motivation

The aexpansion is meant to avoid incompatibility with deterministic wallet implementations across the Aeternity landscape and to make it easy for the derivation path to be found.

Specification

Accounts derivation path is taken from , except that in all path segments hardened derivation is used since does not support public derivation.

The derivation path (m/purpose'/coin_type'/account_index'/change'/address_index') is therefore:

m/44H/457H/${account_index}H/0H/${address_index}H

where account_index and address_index are integer starting from 0.

References

The coin type value for Aeternity, 457, has been generated on random.org and is registered in .
