DEGEN

−31.8% price impact

High price impact. You'll receive far fewer tokens than you're selling in value. This pool has low liquidity — your trade moves the price.

Set a limit order instead →

Wait for a better price. Your order fills automatically when DEGEN reaches your target — no slippage.

Swap anyway at market price

Solves both issues in one surface Limit order introduced at highest intent moment Warning is clearer — amount loss explained, not implied Danger CTA hierarchy discourages reckless confirm Requires threshold logic (when to show bridge vs. normal warning) Threshold TBD — suggested: show at >10% impact + limit eligible pair

Pre-filled target reduces setup friction Direction auto-inferred (below = buy dip) Offline fill explained inline — trust signal Target price pre-fill logic needs design rule (current market? −30%?) Suggested default: current market price, user edits

WIF

Limit orders not available for WIF. This token isn't on the supported list yet. You can swap at market price, or set a price alert.

Price impact −6.2%

Swap at market price

Doesn't dead-end user — offers price alert as value-add Market swap still available, not blocked Price alert feature is a nice follow-on if not already in product Alert path needs its own design (out of scope this pass)

Proposal — pending approval
Ship Options B + B2 + C as the primary flow: high price impact warning surfaces the limit order CTA (NEYN-11039 + 11022 together), tapping it pre-fills the limit form, review/sign screen surfaces all UniswapX constraints. Mode toggle (Option A) is deprioritised — it adds UI weight to a minority action. Option D (orders history) is required but not blocking. Option E (unsupported token) needed for completeness.

Out of scope this pass: gas estimation, wallet selector, network mismatch, push notification on fill, submitted-order cancel (v1 constraint), price alert feature, pagination in orders history.
