keyring-chatbot-coinpool-test

React chat widget — drops a floating chat button + modal into any React dApp. The widget answers questions and handles wallet / token / NFT lookups in the browser. When it proposes an on-chain action (send / approve / wrap / unwrap / send NFT / swap), it renders a confirmation form and hands the host an unsigned transaction to sign and broadcast.

Install

yarn add keyring-chatbot-coinpool-test
# peer deps
yarn add react react-dom

Peer deps: react / react-dom (17, 18 or 19).

Quick start

import { ChatWidget } from 'keyring-chatbot-coinpool-test';
import type { Transaction, TransactionResult } from 'keyring-chatbot-coinpool-test';

export function App() {
  // Sign + broadcast with your own wallet/provider, then report the result.
  const handleTransaction = async (
    tx: Transaction
  ): Promise<TransactionResult> => {
    try {
      const hash = await wallet.sendTransaction({
        from: tx.from,
        to: tx.to,
        data: tx.data,
        value: tx.value, // wei, decimal string
        chainId: tx.chainId,
      });
      return { status: 'success', transactionHash: hash };
    } catch (err) {
      return { status: 'fail', error: (err as Error).message };
    }
  };

  return (
    <ChatWidget
      account={{ address: '0x…', chainId: 8453 }}
      language="en"
      position="bottom-right"
      theme={{ buttonSize: 56 }}
      onTransaction={handleTransaction}
    />
  );
}

The widget creates one chat session per mount, persists history in localStorage, and forwards the connected wallet address + chain so wallet / token / NFT lookups have the context they need.

The session is built once on mount. Changing account's address/chain after mount does not rebuild it — remount the widget with a new React key (e.g. key={`${address}-${chainId}`}) when you want a fresh session on account switch.

When the widget renders

<ChatWidget> returns null (renders nothing) unless both:

1. account.address is a valid address and account.chainId is set, and
2. the current window.location.origin is allowed.

Origins are gated by WHITELIST_ORIGIN in src/shared/app.ts. localhost always passes for local dev; an empty whitelist disables the gate.

onTransaction

Invoked when the user confirms an action form (send / approve / wrap / unwrap / send_nft) or a buy/swap confirmation. The widget passes an unsigned transaction; the host signs, broadcasts, and returns the result. Required for any on-chain action — without it the widget can only answer questions.

type Transaction = {
  from: string;
  to: string;
  data: string;
  value: string; // wei, decimal string
  chainId?: number | string;
  gasLimit?: string;
  gasPrice?: string;
  maxFeePerGas?: string;
  maxPriorityFeePerGas?: string;
  nonce?: number;
};

type TransactionResult = {
  status: 'success' | 'fail';
  transactionHash?: string;
  error?: string;
};

Before signing, the widget pre-flights the tx against the wallet's native balance (gas + value). If it can't cover it, the widget posts an "insufficient gas" message in the user's language and never calls onTransaction. A flaky RPC fails open — the wallet stays the final gatekeeper.

Props

| Prop | Type | Default | Notes | | ----------------------- | ----------------------------------------------- | ---------------- | --------------------------------------------------------------------- | | account | { address: string; chainId: number \| string }| — | Connected wallet. Required for the widget to render. | | onTransaction | (tx) => Promise<TransactionResult> | — | Sign + broadcast handler. Required for on-chain actions. | | language | 'en' \| 'ja' \| 'cn' | 'en' | UI language. Per-message language from the agent is honored too. | | rpcUrls | Record<number, string> | built-in | RPC per numeric chainId. Merged over the built-in defaults. | | position | 'bottom-right' \| 'bottom-left' | 'bottom-right' | Anchor of the floating button + modal. | | theme | ChatWidgetTheme | {} | primaryColor, buttonSize, zIndex, modalChatStyle, offset. | | defaultOpen | boolean | false | Open the modal on mount. | | onOpen / onClose | () => void | — | Fired when the modal opens / closes. | | chatTitle | string | built-in | Header title. | | welcomeMessage | string | localized | First bot bubble. | | customSuggestions | SuggestionButtonConfig[] | built-in chips | Replace the default suggestion chips. | | additionalSuggestions | SuggestionButtonConfig[] | — | Append extra chips after the base set. | | buttonIcon | string | — | Custom floating-button icon. | | chatIcon | string | built-in | Header / avatar icon. | | customChatButton | ReactNode | — | Replace the floating button entirely. | | styleButtonChat | CSSProperties | — | Extra styles on the floating container. | | modalConfig | { isShowIcon?: boolean } | {} | Modal-level toggles. |

SuggestionButtonConfig is { icon?: string; text: string }.

Agent behavior (model, subagents, storage key, data sources, …) is not a prop — it's fixed by the package descriptor in src/shared/app.ts. The only agent-related prop is rpcUrls.

Prop details & examples

account (required to render)

The connected wallet. Pass undefined while disconnected — the widget then renders nothing. chainId may be a number (8453) or hex string ("0x2105").

<ChatWidget account={{ address: '0xAbc…123', chainId: 8453 }} />

// Disconnected → widget renders null:
<ChatWidget account={connected ? { address, chainId } : undefined} />

Remount on identity change to start a fresh session:

<ChatWidget key={`${address}-${chainId}`} account={{ address, chainId }} />

onTransaction (required for on-chain actions)

Called when the user confirms a wallet action. Sign + broadcast, then return the result. See onTransaction for the full Transaction / TransactionResult shapes.

<ChatWidget
  account={{ address, chainId }}
  onTransaction={async (tx) => {
    try {
      const hash = await wallet.sendTransaction(tx);
      return { status: 'success', transactionHash: hash };
    } catch (e) {
      return { status: 'fail', error: (e as Error).message };
    }
  }}
/>

language

UI language for the widget's own strings: 'en' | 'ja' | 'cn'. The agent also tags each reply with a language, which is honored per-message.

<ChatWidget account={acct} language="ja" />

rpcUrls

Override RPC endpoints, keyed by numeric chainId. Merged over the built-in defaults, so you only list the chains you want to change.

<ChatWidget
  account={acct}
  rpcUrls={{
    1: 'https://my-eth-rpc.example',
    8453: 'https://my-base-rpc.example',
  }}
/>

position

Which corner the floating button + modal anchor to: 'bottom-right' (default) or 'bottom-left'.

<ChatWidget account={acct} position="bottom-left" />

theme

type ChatWidgetTheme = {
  primaryColor?: string;
  buttonSize?: number; // px
  zIndex?: number;
  modalChatStyle?: React.CSSProperties; // styles on the modal surface
  offset?: { x: number; y: number }; // px from the anchored corner
};

<ChatWidget
  account={acct}
  theme={{
    primaryColor: '#0b3988',
    buttonSize: 56,
    zIndex: 9999,
    offset: { x: 24, y: 24 },
    modalChatStyle: { width: 420, maxHeight: '70vh' },
  }}
/>

defaultOpen, onOpen, onClose

Open on mount and observe open/close.

<ChatWidget
  account={acct}
  defaultOpen
  onOpen={() => analytics.track('chat_open')}
  onClose={() => analytics.track('chat_close')}
/>

chatTitle, welcomeMessage

Header title and the first bot bubble.

<ChatWidget
  account={acct}
  chatTitle="Ask Keyring"
  welcomeMessage="Hi! Ask me about your wallet, tokens, or NFTs."
/>

customSuggestions vs additionalSuggestions

Suggestion chips above the input. customSuggestions replaces the built-in set; additionalSuggestions appends after the base set. Each chip is { icon?: string; text: string } — text is sent as the prompt when tapped.

// Replace the defaults entirely:
<ChatWidget
  account={acct}
  customSuggestions={[
    { icon: '💸', text: 'Send 0.01 ETH' },
    { icon: '📈', text: 'Show my token balances' },
  ]}
/>

// Keep the defaults, add two more:
<ChatWidget
  account={acct}
  additionalSuggestions={[{ icon: '🖼️', text: 'List my NFTs' }]}
/>

buttonIcon, chatIcon

Image URLs. buttonIcon is the floating button; chatIcon is the header / avatar icon.

<ChatWidget
  account={acct}
  buttonIcon="https://cdn.example/chat.png"
  chatIcon="https://cdn.example/avatar.png"
/>

customChatButton

Replace the floating button with your own node. The widget still owns the open/close behavior, so render a presentational element (no onClick needed).

<ChatWidget
  account={acct}
  customChatButton={
    <div className="my-fab">
      <img src="/chat.svg" alt="" /> Chat
    </div>
  }
/>

styleButtonChat

Extra inline styles applied to the floating container (merged over the position/offset styles).

<ChatWidget account={acct} styleButtonChat={{ bottom: 96, right: 32 }} />

modalConfig

Modal-level toggles. Currently { isShowIcon?: boolean } (default true) — set false to hide the header icon.

<ChatWidget account={acct} modalConfig={{ isShowIcon: false }} />

A fuller example

import { ChatWidget } from 'keyring-chatbot-coinpool-test';
import type { Transaction, TransactionResult } from 'keyring-chatbot-coinpool-test';

export function Chat({ address, chainId, connected }) {
  const onTransaction = async (tx: Transaction): Promise<TransactionResult> => {
    try {
      const hash = await wallet.sendTransaction(tx);
      return { status: 'success', transactionHash: hash };
    } catch (e) {
      return { status: 'fail', error: (e as Error).message };
    }
  };

  return (
    <ChatWidget
      key={`${address}-${chainId}`}
      account={connected ? { address, chainId } : undefined}
      onTransaction={onTransaction}
      language="en"
      position="bottom-right"
      theme={{ primaryColor: '#0b3988', buttonSize: 56, offset: { x: 24, y: 24 } }}
      chatTitle="Ask Keyring"
      welcomeMessage="Hi! Ask me about your wallet, tokens, or NFTs."
      additionalSuggestions={[{ icon: '🖼️', text: 'List my NFTs' }]}
      rpcUrls={{ 8453: 'https://my-base-rpc.example' }}
      onOpen={() => console.log('opened')}
    />
  );
}

Clearing history

Reset the active widget's chat history imperatively — e.g. on logout — without holding a ref:

import { clearChat } from 'keyring-chatbot-coinpool-test';

function onLogout() {
  clearChat(); // clears in-memory + localStorage history and re-shows suggestions
}

Compose your own UI

For a custom layout that reuses the same wiring, skip <ChatWidget> and compose the providers + hooks yourself:

import {
  ConfigProvider,
  ConnectProvider,
  LanguageProvider,
  useAgent,
  useAgentChat,
  ActionForm,
} from 'keyring-chatbot-coinpool-test';

• useAgent() — builds the per-session chat agent (config-driven; takes no args).
• useAgentChat({ agent, addMessage }) — send(text) → reply + wallet actions.
• ActionForm — the confirmation form primitive for a wallet action.
