Confirmation Semantics and Finality Boundaries

WAproxy separates broadcast success from confirmation finality.

Broadcast success means:

• transaction accepted by local node

• transaction propagated to mempool

Confirmation means:

• transaction included in a block

• block depth >= required confirmations

WAproxy does not assume immediate finality.

Execution layers:

1. Broadcast Layer

• returns txid

• does not guarantee inclusion

1. Confirmation Layer

• tracks block depth

• evaluates confirmation threshold

Applications must define:

required_confirmations >= 1

Example policy:

low-value payment:
required_confirmations = 1

high-value payment:
required_confirmations = 3 or more

wallet_balance behavior:

• unconfirmed outgoing reduces available balance

• confirmed outgoing finalizes deduction

WAproxy does not enforce confirmation policy.
It exposes transaction state deterministically.

Finality belongs to application logic.

WAproxy transports value.
Confirmation defines settlement certainty.
