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
- Call
GET /v2/quote?mode=DELTA instead of GET /prices. Treat a missing delta block as a routing failure for your UX.
- Remove Augustus calldata signing paths. All execution goes through
/v2/delta/orders.
- 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.Last modified on June 14, 2026
