SUBTC — Bitcoin-Only Protocol Overview
SUBTC Protocol focuses exclusively on Bitcoin.
It provides a deterministic, stateless API for automated BTC payments and wallet management.
- 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.
- 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.
- 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
- Payment Flow
Pattern:
- create wallet
- generate address
- send BTC
- confirm via poll or webhook
- execute dependent action
All predictable and reliable.
- Fee Structure
- min_send_sat: 50,000
- fee: 3%
- deterministic rounding
- all values in satoshi
Example:
0.00015000 BTC → 15,000 sat
