Feature Catalog

Everything ChainRender can do, at a glance. This is the complete feature surface — scan it to see what's available, then follow the links for detail. Every item here is built and fully on-chain unless noted.

Core

Feature	What it does	Grade
Content-addressed apps	An app is its hash; immutable, verifiable, permanent	A
Free rendering	`renderHash` — a `view` call, no gas, reproducible on any RPC	A
Trust grade	Automatic A/B/C grade + itemized deviations, drift-locked to the chain	—
Capability enforcer	Refuses unsafe apps at registration (rails R1–R7)	—
The floor	Every app has a complete on-chain floor; enhancements fail closed to it	A

UI primitives (the vocabulary)

box · text · heading · button · link · icon · input · image · slot · ref — the closed set you compose from. Plus the structured renderers below.

Structured components

Component	Renderer	Notes
Charts	`ChartRenderer`	line / area / bar / scatter / pie / donut; themed; self-correcting layout
Tables	`TableRenderer`	static / bound / paginated; structured cells
Controls	`ControlRenderer`	toggle / select / slider / search — bound to display params, never consequences
Layout	`LayoutRenderer`	stacks / grids / flow + responsive breakpoints
Routes	`RouteRenderer`	swap route diagrams, any topology (single/multi-hop/split)
Source code	`SourceRenderer`	render code on-chain, line-numbered, escaped

Navigation & composition

Feature	What it does
Multi-view apps	tabs / wizard / master-detail / modal templates (see App Templates)
Mini-apps	content-addressed, composable app manifests
App DNA / forking	forks record their parent on-chain (verifiable lineage)

Data & actions

Feature	Capability
Live data binding	on-chain reads via resolvers (READ_CHAIN)
Protocol integrations	Chainlink (price + live history chart), Uniswap V3/V4, Aave, Curve, ERC-20/721, ENS, EAS, Proof-of-Reserve, ERC-3643 — see Data Sources
Batched reads	multicall in one round-trip
Events	on-chain log reads
Declared actions	construct-for-sign; a button can only do what it declares (WRITE_CHAIN)
Batched actions	N actions, one signature, individually gated (BATCH_EXECUTE)
Typed signing	EIP-712 (SIGN_MESSAGE) · signature verification (ERC-1271/6492)
Value transfer	gated by an explicit VALUE declaration

Visual & media (all on-chain, Grade A)

Generative art · gradient identicons · high-fidelity vector art · SDF 2D/3D scenes (+ optional GPU enhancement) · point clouds · fully on-chain cartography · declarative SVG animation · post-processing effects (CRT/glass/…) · on-chain NFT media · media provenance · p5.js & three.js rich media (client-side, over an on-chain floor, with the library stored on-chain). See Visual & Media Capabilities and Rich Media: p5.js & three.js.

Identity, reputation & privacy

ENS profiles (live on-chain identity UI) · attested identity claims (EAS) · selective-disclosure credentials (ZK, member-of-set) · bound single-use credentials · EFP social graph (forward follow/tag/block/mute reads, Grade A) · delegated address vouching (ownerless rep-vouch/rep-tally, ≤ C) · cross-source reputation aggregate (rep-aggregate, grade = weakest source) · ERC-725Y / ERC-735 account claim reads (via staticread, same-chain, ≤ C — the standard behind LUKSO Universal Profiles; LUKSO's chain is not integrated). Unified via a common privacy convention and the reputation resolver family. See Reputation Capabilities.

Presentation & theming

Design-token system (W3C-aligned) · light / dark / high-contrast presets · render-time theming (zero-gas) · whole-page zero-gas UX iteration · ThemeSets (theme registry) · series palettes · contrast + legibility invariants. See Theming and Themes in Depth.

Naming, versioning & trust signals

Component annotations (ownerless append-only metadata) · Subnames under chainrender.eth (ownerless registrar + ENSIP-10 wildcard) · versioned names (append-only + timelock) · advisories (alert) · attestations (vouch).

Storage & serving

SSTORE2 content storage · paginated chunked reads (IChunkedRender) · web3:// serving (ERC-5219/4804).

Developer tooling

@chainrender/client SDK (core + /runtime + /react + /miniapp) · create-chainrender scaffolder · @chainrender/mcp (AI builds apps via MCP tools) · app-builder skill · local grade/preview/validate before deploy · Farcaster Mini App distribution. Every integration is indexed for the builder + AI in Integrations & Libraries.

Deployment

Legend: Grade A = fully on-chain, trustless. A dependency that reaches off-chain (a declared CLIENT_FETCH) lowers the grade and is disclosed — see The Trust Grade.

Recently added

On-chain icons -- ~500 Lucide icons stored on-chain, used via the icon node, theme-adaptive. See On-Chain Icons.
Apps directory -- a header-linked page listing deployed apps (read on-chain from SceneComponentRegistry, self-updating) + first-party tools. See The Apps Directory.
Human-readable action decoding -- a plain-English "you see what you sign" decode of any declared action, with a swap honesty flag. See Actions & Signing.
Uniswap V4 price rendering + generic hook/contract reads (staticread). See Rendering Uniswap Hooks.
Optional project encryption in the builder (opt-in, WebCrypto, no fake recovery). See Privacy & Credentials.
AI-assisted repair -- when a generated sketch errors, a "Fix with AI" loop feeds the error back to the model.
Two-layer test harness -- headless integration checks + a browser smoke test. See Testing.
DeFi frontends (comprehensive) — render market prices, a user's LP + lending positions (with health factor), pre-trade quotes, approval state, and portfolio totals; declare swaps/approves/deposits as decoded actions. Full guide: DeFi Capabilities.
Payments (crypto + optional card on-ramp) — add a payment to any app: the crypto payment is a trustless on-chain action (Grade A), and an optional fiat/card on-ramp (your chosen provider) is honestly graded off-chain (≤ C). Non-native users get a card path without overstating the on-chain guarantee. See Payments.
Reputation (EFP + delegated vouching + aggregate) — render an address's on-chain social graph via EFP (forward follow/tag/block/mute, Grade A), delegated vouches under caller-chosen topics (rep-vouch/rep-tally, ≤ C), and a transparent cross-source aggregate whose grade is capped at the weakest source (rep-aggregate) — plus ERC-725Y / ERC-735 account claim reads (same-chain, ≤ C; the standard behind LUKSO Universal Profiles, though LUKSO's chain is not integrated). Read + render reputation, never mint a score. Full guide: Reputation Capabilities.
RWA (real-world assets) — render Proof-of-Reserve coverage (reserves ÷ supply, with freshness; por-coverage/por-reserves/por-supply, Grade A), ERC-3643 (T-REX) compliance state (verified/frozen/can-transfer; erc3643-*, display-only, ≤ C), and issuer-bound credential lifecycle (cred-status/cred-valid). Display compliance, never become the compliance authority. Full guide: RWA Capabilities.
