# Archetype is securing the software supply chain for the Open Web with decentralized package management infrastructure. **Global Type Registry (GTR)** - first-principles meta-package registry for sovereign software, information, & value. - Deep introspection & cryptographic verifiability across context-rich dependency graphs, onchain routing, standard adherence, trust assumptions, & supply chain axioms. **Metadata graph** - Networked metadata layer for rich context on GTR packages. - An open commons of audits, attestations, & arbitrary context explicitly linked to packages & versioned contract deployments, using ontology-agnostic linked data & semantic constructions **Curation layer** - Decentralized discovery, indexing, & aggregation layer. - An sdk & contract suite for surfacing, filtering, & aggregating packages along arbitrary dimensions
