Derivation Paths
The hierarchical path that encodes program, group, tier, and sequence into every badge.
Every badge's keys derive from the program's master key via a
hierarchical path of the form m/721'/0'/{group}'/{tier}'/{seq}.
The path makes group and tier structural properties of the badge
rather than mutable metadata.
This page is being written.
The structure is fixed. The prose is being drafted from the source material and reviewed by HeartChain Labs before publication. If you need this information urgently, email docs@heartbadge.com .
