Contracts: Architecture

The on-chain system, in layers:

  • Storage — component bytes stored via SSTORE2 (SourceStore/ChunkedStore): pay gas once to write, render free forever.
  • Registry — ComponentRegistry maps a hash → its bytes (content-addressed). AppRegistry, CompositionRegistry track apps, mini-apps, and fork lineage.
  • Interpreter / Router — RenderRouter + OpcodeInterpreterV3Html walk the byte tree and emit HTML/SVG; a view call, deterministic, fail-closed.
  • Resolvers — the data/media library, each a small view contract.
  • Enforcer — TrustGrade + ActionVocab: grades and refuses, on-chain, drift-locked with the SDK.
  • Theming — ThemeTokens + ThemeCssView generate CSS from tokens; PresentationContext applies theme at render time.
  • Registries (governance-free) — SubnameStakeRegistrar (names), SubnameVersionRegistry (versions), ThemeSetRegistry (themes), AdvisoryRegistry/AttesterRegistry (advisories/attestations).

Every contract is ownerless and immutable — no admin, no upgrade key. Verify once, rely forever.
