Stack Layers
The Infrastructure Stack
Every namespace in the registry maps to a layer in the Web3 protocol stack. The layers are stacked from foundation upward — substrate primitives at the bottom, enterprise applications at the top. Chip counts reflect the live portfolio.

Canonical Primitives — Core Infrastructure Names
These are the category-defining namespaces — the canonical root for each vertical. Our April 2026 on-chain record batch includes the canonical standards names aligned with ERC-7828, ERC-7930, and ENSIP-24 (highlighted below). These names have no synonyms — they are the infrastructure.
