The Bitte AI Chat component is a React component that enables AI-powered chat interactions in your application. It supports both NEAR Protocol and EVM blockchain interactions through wallet integrations, allowing users to interact with smart contracts and perform transactions directly through the chat interface.
🔑 Before you begin, make sure you have:
- A Bitte API Key - Get yours here
Our stable version (latest) currently supports React 18 Applications. We have a beta version that supports React 19 and Next.js 15 Applications.
We are working on support more frameworks like Vite React 19 in the mean time.
You can check an working Next.js example on our chat-boilerplate repo
Run on Stackblitz
We recommend installing the package using pnpm or yarn:
pnpm install @bitte-ai/chat
or
yarn add @bitte-ai/chat
if you are using npm and find issues, you can use the current command:
npm install @bitte-ai/chat --legacy-peer-deps
You can integrate with NEAR using either the NEAR Wallet Selector or a direct account connection. If you want to be able to send near transacitons through the chat you will need to define at least one of these
Check our Next.js boilerplate repo. Currently turbopack builds arent working due to tailwind build issue.
-
You need to wrap your application with BitteWalletContextProvider
-
If you using Next.js you need to add
"use client"
on top of file
import { useEffect, useState } from "react"
import { useBitteWallet, Wallet } from "@bitte-ai/react";
import { BitteAiChat } from "@bitte-ai/chat";
import "@bitte-ai/chat/style.css";
export default function Chat() {
const { selector } = useBitteWallet();
const [wallet, setWallet] = useState<Wallet>();
useEffect(() => {
const fetchWallet = async () => {
const walletInstance = await selector.wallet();
setWallet(walletInstance);
};
if (selector) fetchWallet();
}, [selector]);
return (
<BitteAiChat
agentId="your-agent-id"
apiUrl="/api/chat"
wallet={{ near: { wallet } }}
/>
);
}
import { Account } from "near-api-js";
// get near account instance from near-api-js by instantiating a keypair
<BitteAiChat
agentId="your-agent-id"
apiUrl="/api/chat"
wallet={{ near: { account: nearAccount } }}
/>
EVM integration uses WalletConnect with wagmi hooks:
import { useSendTransaction, useAccount } from 'wagmi';
export default function Chat() {
const { address } = useAccount();
const { sendTransaction } = useSendTransaction();
return (
<BitteAiChat
agentId="your-agent-id"
apiUrl="/api/chat"
wallet={{
evm: {
sendTransaction,
address
}
}}
/>
);
}
Create an API route in your Next.js application to proxy requests to the Bitte API to not expose your key:
import type { NextRequest } from "next/server";
const { BITTE_API_KEY, BITTE_API_URL = "https://wallet.bitte.ai/api/v1/chat" } =
process.env;
export const dynamic = "force-dynamic";
export const maxDuration = 60;
export const POST = async (req: NextRequest): Promise<Response> => {
const requestInit: RequestInit & { duplex: "half" } = {
method: "POST",
body: req.body,
headers: {
Authorization: `Bearer ${BITTE_API_KEY}`,
},
duplex: "half",
};
const upstreamResponse = await fetch(BITTE_API_URL, requestInit);
const headers = new Headers(upstreamResponse.headers);
headers.delete("Content-Encoding");
return new Response(upstreamResponse.body, {
status: upstreamResponse.status,
headers,
});
};
Create an API route in your Next.js application that will allow your app if you want to save chat context when signing a transaction after getting redirected to the wallet.
import { type NextRequest, NextResponse } from 'next/server';
const { BITTE_API_KEY, BITTE_API_URL = 'https://wallet.bitte.ai/api/v1' } =
process.env;
export const dynamic = 'force-dynamic';
export const maxDuration = 60;
export const GET = async (req: NextRequest): Promise<NextResponse> => {
const { searchParams } = new URL(req.url);
const id = searchParams.get('id');
const url = `${BITTE_API_URL}/history?id=${id}`;
const response = await fetch(url, {
headers: {
Authorization: `Bearer ${BITTE_API_KEY}`,
},
});
const result = await response.json();
return NextResponse.json(result);
};
