const apiKey = process.env.CROSSMINT_STAGING_API_KEY;
const walletSignerSecretKey = process.env.SIGNER_WALLET_SECRET_KEY;

const smartWalletAddress = process.env.SMART_WALLET_ADDRESS;

const { smartwallet } = crossmint(apiKey);

const tools = await getOnChainTools({
    wallet: await smartwallet({
        address: smartWalletAddress,
        signer: {
            secretKey: walletSignerSecretKey as `0x${string}`,

const email = process.env.EMAIL;

if (!apiKey || !email) {
    throw new Error("Missing environment variables");
}

const { custodial } = crossmint(apiKey);

const tools = await getOnChainTools({
    wallet: await custodial({
        chain: "solana",
        email: email,
        env: "staging",
        connection: new Connection(

import { getOnChainTools } from "@goat-sdk/adapter-vercel-ai";
import { viem } from "@goat-sdk/wallet-viem";
import { crossmint } from "@goat-sdk/crossmint";

const account = privateKeyToAccount(
    process.env.WALLET_PRIVATE_KEY as `0x${string}`
);

const walletClient = createWalletClient({
    account: account,
    transport: http(process.env.ALCHEMY_API_KEY),
    chain: sepolia,
});

const apiKey = process.env.CROSSMINT_STAGING_API_KEY;

const { faucet } = crossmint(apiKey);

const tools = await getOnChainTools({
    wallet: viem(walletClient),
    plugins: [faucet()],
