# Replace Market with Delta

> When and how to fully cut over from Market routing to Delta intents.

## What breaks if you do nothing

Nothing. Market routing isn't going away. This migration is for teams who want to consolidate on Delta for product reasons, not a forced cutover.

## When to fully cut over

* Gasless UX is a real differentiator for your users (consumer wallets, agent flows, sub-\$50 swaps).
* MEV is a known problem in your current Market flow, typically on large trades or low-liquidity pairs.
* You want the surplus: solver competition routinely returns positive slippage to your users on Delta orders.

## When to keep Market

* Latency budget under \~1s end-to-end.
* Heavy token coverage on pairs that Delta solvers don't yet quote.
* You already amortize gas across many users (batched executor, account abstraction with paymaster).

## Steps

1. Call `GET /v2/quote?mode=DELTA` instead of `GET /prices`. Treat a missing `delta` block as a routing failure for your UX.
2. Remove Augustus calldata signing paths. All execution goes through `/v2/delta/orders`.
3. Update your token-approval flow: the Delta contract, not Augustus, is the spender.

## End-state check

Wallet, balance, and history pages show only Delta-style settlements. Augustus calldata flow is no longer reachable from your UI.
