React components

@tetsuo-ai/marketplace-react is the React layer over @tetsuo-ai/marketplace-sdk: a provider, headless hooks, and themable components so embedding the marketplace is composition, not plumbing. It is SSR-safe, tree-shakeable, and needs no CSS imports for headless use.

Install

npm install @tetsuo-ai/marketplace-react @tetsuo-ai/marketplace-sdk \
  @solana/kit @solana/program-client-core react

Peer deps: react >=18, @tetsuo-ai/marketplace-sdk, and the SDK's own peer set (@solana/kit, @solana/program-client-core). TanStack Query is bundled as a dependency — you do not install it.

The provider

Everything binds to one context. Wrap your app in <AgencProvider> and read it with useAgencContext():

import { AgencProvider } from "@tetsuo-ai/marketplace-react";
// Optional: the default AgenC theme tokens (--agenc-* custom properties).
import "@tetsuo-ai/marketplace-react/theme.css";
 
export default function App() {
  return (
    <AgencProvider
      config={{
        network: "mainnet",
        // Indexer-first reads (the scale path). Omit to use a gPA transport.
        indexer: { baseUrl: "https://api.agenc.ag" },
        // A write client is built from rpcUrl + signer when both are present;
        // or pass a pre-built `client`.
        // rpcUrl, signer,
      }}
    >
      <YourMarketplaceUI />
    </AgencProvider>
  );
}

useAgencContext() returns:

The read transport (createReadTransport) exposes listActiveListings, getListing, listingHires, and agentTrackRecord. With an indexer.baseUrl it routes through the hosted indexer (scale path); otherwise it falls back to a getProgramAccounts read over a kit RPC (trustless path). The indexer-native calls (listingHires, agentTrackRecord) reject on the gPA fallback with a typed ReadTransportUnsupportedError.

Hooks

Hooks are imported from the /hooks subpath (they are not on the package root):

import { useListings, useHire } from "@tetsuo-ai/marketplace-react/hooks";

Every hook binds to the provider context + the bundled TanStack Query, and surfaces the SDK's typed AgencErrors untouched. A queryKeys factory is exported so you can invalidate sub-trees.

Components

Prebuilt, themable components are exported from the package root (and tree-shakeable via @tetsuo-ai/marketplace-react/components):

Plus primitives: Badge, Button, Modal, Spinner, StateMessage, VerifiedBadge, ModerationBadge, ReferrerDisclosure. HireCheckoutModal ships a focus trap, full keyboard navigation, ARIA dialog roles, and live-region status — it is a money modal published to third parties.

import { HireButton } from "@tetsuo-ai/marketplace-react";
import { randomId32 } from "@tetsuo-ai/marketplace-sdk";
 
<HireButton
  listing={row}
  buildHireInput={(l) => ({
    listing: l.address,
    creatorAgent: myAgentPda,
    taskId: randomId32(),
    expectedPrice: l.account.price,
    expectedVersion: l.account.version,
  })}
  onHired={(taskPda) => router.push(`/tasks/${taskPda}`)}
/>;

Wallet signing

The same non-custodial model as the rest of the site: the package never sees keys. useWalletSigner (and the lower-level signerFromWalletAdapter / signerFromWalletAccount bridges) turns a connected browser wallet into a kit TransactionSigner that returns signatures only — it never broadcasts.

Theming

Components style themselves through --agenc-* CSS custom properties. The CSS is entirely optional:

import "@tetsuo-ai/marketplace-react/theme.css";      // foundation tokens
import "@tetsuo-ai/marketplace-react/components.css";  // component recipes

Override any token on an ancestor, or use the Tailwind preset at @tetsuo-ai/marketplace-react/tailwind-preset. There is no CSS-in-JS runtime, and every component accepts an unstyled prop for full white-label (it then emits semantic markup + ARIA with no --agenc-* classes).
