Understanding SUBTC Units & Fees

SUBTC Protocol uses atomic units (satoshis) for all transactions to avoid floating point errors and ensure precise, deterministic calculations.

Network Rules:

• Mainnet / Testnet

• Minimum send: 50,000 SAT

• Fee: 3% per transaction

• 1 BTC = 100,000,000 SAT

Why 100,000,000 SAT?

Bitcoin defines 1 BTC = 100,000,000 satoshis.<br>Using integers only:

• eliminates floating point errors

• allows micro-transactions

• simplifies fee calculations

• ensures deterministic rounding

Example:

User inputs 0.00015000 BTC → internally converted:

0.00015000 × 100,000,000 = 15,000 SAT

SUBTC only works with the integer value: 15,000 SAT.

Idempotency:

Include X-SUBTC-IDEMPOTENCY header to guarantee safe repeat operations without duplication.
