# V3 Improvements

> An overview of the V3 exchange model and how it's structured.

## V3 Improvements

<Warning>
  V3 is currently live on **testnet only**. Do not point a production integration at V3 until **August 25th at 10:00 AM EST** — until then, target V3 on testnet and keep production on V2.
</Warning>

V3 rebuilds the exchange around the proxy-wallet model below. What you get for it:

* **Reliable settlement** — the fill failures of V2 are eliminated.
* **Elimination of trade ordering issues** - race conditions between cancels and fills are eliminated.
* **Faster orders API** — placing an order via [`POST /orders-v3`](/api-reference/post-orders-v3) is roughly 50% lower latency than V2.
* **Faster confirmation** — the time from placing a bet to on-chain settlement drops 2–3×.
* **Automatic order bashing** — an order whose price crosses the book fills immediately against resting liquidity instead of resting.
* **Withdrawal controls** — you can add multiple signers to your wallet to approve withdrawals. See [Accounts](/developers/accounts).
* **Privacy** — your orders, positions and trades are not attributable to your address.

## Capital lives in a proxy wallet

Every bet is placed, collateralised and paid out through a proxy contract you own, not your EOA / user address.

## One signed order does everything

Every order — a resting quote or an immediate bet — is a call submitted to
[`POST /orders-v3`](/api-reference/post-orders-v3). `timeInForce` sets its behaviour: `GTC` rests on
the book ("maker" orders), `IOC` and `FOK` execute against it immediately ("taker" or "market" orders).

## The order book is aggregated and anonymous

The public book is price levels, not individual orders. Each snapshot carries a `version`, so you can reconcile a REST seed against the realtime stream and always keep the newer
state.

## Your activity is private

The public book shows aggregated price levels, not individual orders, so your resting quotes are not
attributable to you.
