Quick start

npm install @chipi-stack/core @chipi-stack/backend

import { ChipiSDK } from "@chipi-stack/backend";

const chipi = new ChipiSDK({
  apiPublicKey: "pk_prod_...",
  apiSecretKey: "sk_prod_...",
});

// Create a gasless wallet
const wallet = await chipi.createWallet({ ownerId: "user_123" });

// Send USDC (zero gas fees)
const tx = await chipi.transferToken({
  senderAddress: wallet.publicKey,
  recipientAddress: "0x...",
  amount: "10",
  tokenAddress: "USDC",
});
