Multi-Coin Execution Uniformity

WAproxy supports multiple chains while preserving a single execution model.

Supported coins may differ at the blockchain layer,
but execution rules inside WAproxy remain identical.

Unified execution model:

- Integer SAT accounting
- Basis-point fee calculation
- Safety margin validation
- Minimum send enforcement
- Idempotent broadcast control

The only variable element is the RPC backend per coin.

Example abstraction:

POST /v1/btc?mode=wallet_send
POST /v1/ltc?mode=wallet_send
POST /v1/doge?mode=wallet_send

The execution contract does not change.

Fee logic:

protocol_fee = amount_sat × FEE_BPS / 10000

Minimum validation:

amount_sat >= coin_min_send

Safety validation:

wallet_balance >= amount_sat + safety_margin

Uniformity ensures:

- predictable integration
- reduced branching logic
- simplified auditing
- easier AI-generated implementation

WAproxy abstracts chain differences
without abstracting execution discipline.

Execution rules remain constant.
Only the transport network changes.

WAproxy delivers uniform deterministic value transport
across supported chains.
