The **SUBTC Protocol** provides a lightweight, secure, and AI-friendly Bitcoin execution layer. Integrating it with **WordPress** allows developers to build **BTC payment gateways** for various services such as marketplaces, hosting, and marketing platforms.

Base API: https://subtc.net/api

## 1. Architecture Overview

**Core Components:**

- **WordPress Frontend:** Acts as the user interface.
- **SUBTC Protocol:** Handles wallet management, payments, and confirmations.
- **API Connector:** PHP or REST client to call SUBTC endpoints.
- **Optional AI Agents:** Automate order fulfillment, notifications, or dynamic pricing.

**Flow:**

User → WordPress (checkout page) → SUBTC API → Bitcoin Network → Confirmation → Order Fulfillment

## 2. Wallet Management

Each customer or service can have **dedicated wallets**. Use the SUBTC API for:

1. **Create Wallet**

$resp = curl_post("https://api.subtc.net/v1/btc?mode=wallet_create", ['net' => 'main']);
$wallet_id = $resp['wallet_id'];

2. Generate Receiving Address

$resp = curl_post("https://api.subtc.net/v1/btc?mode=wallet_receive", ['wallet_id'=>$wallet_id]);
$address = $resp['address'];

3. Check Balance

$resp = curl_post("https://api.subtc.net/v1/btc?mode=wallet_balance", ['wallet_id'=>$wallet_id]);
$balance = $resp['result']['balance_sat'];

---

3. Payment Flow Strategy

1. Customer selects service (hosting, marketplace item, marketing service).

2. Generate SUBTC receiving address for the transaction.

3. Display QR code or BTC link on WordPress checkout.

4. Monitor payment using:

wallet_poll for non-blocking checks

wallet_wait_event for webhook or long polling confirmation

$resp = curl_post("https://api.subtc.net/v1/btc?mode=wallet_wait_event", [
  'wallet_id'=>$wallet_id,
  'address'=>$address,
  'expected_sat'=>$amount_sat,
  'timeout_sec'=>600,
  'callback_url'=>'https://yourdomain.com/subtc-webhook'
]);

5. Confirm transaction → automatically update order status.

4. Order Fulfillment Automation

Use WordPress hooks to trigger post-payment actions:

Provision hosting accounts

Grant digital product access

Activate marketing services

Optionally integrate AI agents to handle notifications and dynamic pricing.

---

5. Security Best Practices

Do not store SUBTC-KEY in the database. Use .env files or server environment variables.

Use Docker to isolate WordPress + SUBTC integration.

Daily transfers: Move funds from hot wallets to cold storage.

Enable idempotency: Use X-SUBTC-IDEMPOTENCY header to prevent double execution.

6. Use Cases

a. Marketplaces

Sell digital or physical goods

Each vendor can have a SUBTC wallet

Payments automatically processed and verified

b. Hosting Platforms

Customers pay with BTC

SUBTC API handles wallet creation and monitoring

Servers provisioned automatically

c. Marketing Services

Subscription services via BTC

AI agents manage campaign activation upon payment confirmation

---

7. Developer Notes

Prefer PHP with cURL for WordPress backend, but Python or Go microservices can handle heavy automation.

Webhook integration reduces polling load and ensures near real-time confirmations.

Use SUBTC Testnet for sandboxed testing before mainnet deployment.

Conclusion

Integrating SUBTC Protocol with WordPress empowers developers to:

Build autonomous BTC payment gateways

Automate fulfillment for various services

Securely manage wallets without handling sensitive private keys

Scale payment solutions efficiently across marketplaces, hosting, and digital services

The combination of WordPress flexibility + SUBTC’s deterministic, AI-friendly API creates a robust infrastructure for next-gen crypto-enabled platforms.
