SUBTC — Bitcoin-Only Protocol Overview

SUBTC Protocol focuses exclusively on Bitcoin.

It provides a deterministic, stateless API for automated BTC payments and wallet management.

1. Core Philosophy

- 100% Bitcoin (mainnet & testnet)
- Atomic unit handling (satoshi only)
- Deterministic fees (3% service fee)
- Idempotent operations (X-SUBTC-IDEMPOTENCY)

No floats. No multi-coin complexity.

---

2. Wallet Management

Endpoints:

- wallet_create → new wallet
- wallet_receive → generate BTC address
- wallet_balance → check satoshi balance
- wallet_send → execute payment

Supports mainnet & testnet via `net` parameter.

---

3. Event Handling

Two mechanisms:

- wallet_poll → non-blocking single check
- wallet_wait_event → long poll or webhook callback

Enables:

- AI agents
- automation scripts
- trading bots

---

4. Payment Flow

Pattern:

1. create wallet
2. generate address
3. send BTC
4. confirm via poll or webhook
5. execute dependent action

All predictable and reliable.

5. Fee Structure

- min_send_sat: 50,000
- fee: 3%
- deterministic rounding
- all values in satoshi

Example:

0.00015000 BTC → 15,000 sat
