Description

Quotes felt slow to load on Buy (Continue / amount screen loading, modals sluggish) partly because every quote path passed forceRefresh: true and React Query used staleTime: 0, so getQuotes almost always bypassed the ramps controller cache (15s TTL) even when token, amount, provider, and payment method were unchanged.

This PR sets RAMPS_QUOTES_STALE_TIME_MS (15s) on the quotes query—aligned with RampsController DEFAULT_QUOTES_TTL—and stops passing forceRefresh from Build Quote, provider selection, and payment selection so controller + React Query can reuse responses within that window.

Provider list correctness: The provider selection modal filtered the visible list using only the route assetId. When that param was absent but selectedToken was set, the UI could still show every provider while getQuotes used the token from selectedToken, inflating quote work and mismatching the list vs quotes.

This change uses the same effective asset id as quote fetching (paramAssetId ?? selectedToken?.assetId) to derive displayProviders from supportedCryptoCurrencies, so only providers that support the current asset appear and are included in quote params.

Changelog

CHANGELOG entry: Fixed buy flow provider selection so only providers that support the selected asset are shown; improved quote responsiveness by aligning React Query cache with the ramps quotes TTL (15s) and avoiding unnecessary forceRefresh on each fetch.

Manual testing steps

Feature: Ramp buy flow quotes and provider selection

  Scenario: Provider list matches token support without route asset id
    Given user is in the MetaMask buy flow with a token selected
    When user opens the provider selection screen
    Then only providers that declare support for that token asset id are listed

  Scenario: Quotes reuse cache within a short window when inputs unchanged
    Given user is on Build Quote with token, provider, payment method, and amount set
    When user navigates away and back to the same screen without changing those inputs
    Then quote loading should not repeatedly pay full cold-fetch latency where the 15s cache applies
