# Venue adapters

> The capability boundary between Axient accounting and an external event-market venue.

# A venue adapter makes assumptions explicit

Axient is venue-agnostic at the accounting layer, not venue-indifferent. A
venue adapter translates the particular market's order, balance, execution,
settlement, and finality behavior into a bounded interface used by the
reference design.

## Adapter responsibilities

* Describe the market's payoff and outcome-asset relationship.
* Normalize executable order and balance information.
* Identify execution and settlement events.
* Report finality and payout information from the venue.
* State capability limits and reject unsupported transitions.

## Capability before action

An adapter must not imply custody, settlement certainty, or executable
liquidity beyond what the connected venue can actually provide. If a required
capability is absent or uncertain, the related action is restricted rather
than approximated as successful.
