SDK Wallet Operations

Initialize and configure the BankrClient with proper wallet setup.

Two-Wallet System

Wallet	Purpose	Required
Payment (`privateKey`)	Signs x402 micropayments ($0.01/request)	Yes
Context (`walletAddress`)	Receives swapped tokens, NFTs	No (defaults to payment wallet)

Basic Setup

import { BankrClient } from "@bankr/sdk";

const client = new BankrClient({
  privateKey: process.env.BANKR_PRIVATE_KEY as `0x${string}`,
});

const result = await client.promptAndWait({
  prompt: "What are my balances?",
});

Separate Wallets (Recommended)

For enhanced security, use different wallets for payments and receiving:

const client = new BankrClient({
  // Hot wallet with minimal USDC for payments
  privateKey: process.env.PAYMENT_WALLET_PK as `0x${string}`,
  // Cold/trading wallet receives tokens
  walletAddress: process.env.RECEIVING_WALLET,
});

Configuration Options

Option	Type	Required	Description
`privateKey`	`0x${string}`	Yes	Payment wallet private key
`walletAddress`	`string`	No	Override receiving wallet
`baseUrl`	`string`	No	API endpoint (default: production)
`timeout`	`number`	No	Request timeout ms (default: 600000)

SDK Methods

Method	Description
`promptAndWait()`	Submit prompt and wait for result
`prompt()`	Submit prompt, return immediately
`pollJob()`	Poll until job completes
`getJobStatus()`	Check job status once
`cancelJob()`	Cancel pending/processing job
`getWalletAddress()`	Get context wallet address

Per-Request Override

// Override wallet for a single request
const result = await client.promptAndWait({
  prompt: "Swap 0.1 ETH to USDC",
  walletAddress: "0xDifferentWallet...",
});

Environment Setup

# Required
BANKR_PRIVATE_KEY=0x...your_payment_wallet_key...

# Optional
BANKR_WALLET_ADDRESS=0x...your_receiving_wallet...

Security Best Practices

Never commit private keys - Use environment variables
Minimize payment wallet balance - Keep only $1-2 USDC
Use separate wallets - Payment (hot) vs receiving (cold)
Rotate keys periodically - If payment wallet compromised
