WAproxy Multi-Coin Market Send Examples (USDT→BTC/LTC/DOGE) v3

VERSION:
V3 (Philosophy Locked)

DESCRIPTION:
This document demonstrates numeric examples of sending
a market-referenced value (e.g., 10 USDT) across supported coins.

Coins covered:

• BTC

• LTC

• DOGE

Protocol fee:
FEE_BPS = 300 (3%)

------------------------------------------------------------
GLOBAL EXECUTION RULES
------------------------------------------------------------

1) amount_sat is defined by application logic.
2) protocol_fee = amount_sat × 0.03
3) receiver_gets = amount_sat - protocol_fee
4) wallet_balance >= amount_sat + safety_margin
5) network_fee is dynamic and external.
6) All calculations are integer-based.
7) Floating point arithmetic is avoided.

------------------------------------------------------------
SECTION 1 — BTC EXAMPLE
------------------------------------------------------------

Market reference (example snapshot):
10 USDT ≈ 0.00015 BTC

Bitcoin atomic unit:
1 BTC = 100,000,000 sat

Conversion:
0.00015 × 100,000,000 = 15,000 sat

Set:
amount_sat = 15,000

Protocol fee:
15,000 × 0.03 = 450 sat

Receiver gets:
15,000 - 450 = 14,550 sat

Safety margin example:
500 sat

Minimum wallet balance:
15,000 + 500 = 15,500 sat

------------------------------------------------------------
SECTION 2 — LTC EXAMPLE
------------------------------------------------------------

Market reference (example snapshot):
1 USDT ≈ 0.018 LTC
10 USDT ≈ 0.18 LTC

Litecoin atomic unit:
1 LTC = 100,000,000 sat

Conversion:
0.18 × 100,000,000 = 18,000,000 sat

Set:
amount_sat = 18,000,000

Protocol fee:
18,000,000 × 0.03 = 540,000 sat

Receiver gets:
18,000,000 - 540,000 = 17,460,000 sat

Safety margin example:
100,000 sat

Minimum wallet balance:
18,000,000 + 100,000 = 18,100,000 sat

------------------------------------------------------------
SECTION 3 — DOGE EXAMPLE
------------------------------------------------------------

Market reference (example snapshot):
1 USDT ≈ 10 DOGE
10 USDT ≈ 100 DOGE

Dogecoin atomic unit:
1 DOGE = 100,000,000 sat (internal WAproxy unit)

Conversion:
100 × 100,000,000 = 10,000,000,000 sat

Set:
amount_sat = 10,000,000,000

Protocol fee:
10,000,000,000 × 0.03 = 300,000,000 sat

Receiver gets:
10,000,000,000 - 300,000,000 = 9,700,000,000 sat

Safety margin example:
100,000,000 sat

Minimum wallet balance:
10,000,000,000 + 100,000,000
= 10,100,000,000 sat

------------------------------------------------------------
OPTIONAL REVERSE CALCULATION
------------------------------------------------------------

If exact net delivery is required:

amount_sat = desired_net / 0.97

Applications must handle rounding safely.

CALCULATION CONTRACT (NON-NEGOTIABLE):

• All amounts are integer SAT units.

• Protocol fee is deducted from amount_sat.

• Network fee is deducted from wallet balance.

• Safety margin prevents execution failure.

• WAproxy never guarantees fiat equivalence.

------------------------------------------------------------
PROTOCOL PHILOSOPHY
------------------------------------------------------------

WAproxy does not price assets.
WAproxy executes deterministic value transport.
