1215.0.0

@metamask/ramps-controller 20.1.0

Added

• Add getPaymentMethodsForContext(options) and RampsController:getPaymentMethodsForContext messenger action for context-scoped payment-method retrieval aligned with getQuotes provider resolution (#9801)
  • Supports explicit providers, selected-provider (UB2) context, and headless auto-select / restrict paths, including moneyHeadlessAllProviders widening with allowlist pick-survivor intersection.
  • Request-only by default (updateState unset/false): does not mutate Buy paymentMethods.data / .selected.
  • Fans out per contributing provider and dedupes by canonical payment id, keeping the first-seen entry. Payment-method metadata is provider-invariant: the API serves it from a per-region catalog and the provider query narrows that catalog by id-set membership without rewriting fields, so colliding entries carry identical values.
  • Returns a single provider's payment-method list unchanged; deduping applies only to multi-provider fan-out.
  • Normalizes stored region codes before stateful context writes while keeping missing-region checks fail-closed.
  • Partial provider failures still return methods from successful fetches.
  • Throws when updateState: true resolves more than one provider, before any payment-method fetch is issued. The shared Buy catalog has one slot per region, token, and selected provider, so a fan-out write cannot be ordered against a concurrent one. Callers wanting a multi-provider catalog must pass updateState: false and read the returned methods.
• Export normalizeRampsAssetId() so consuming clients can canonicalize CAIP-19 asset ids the way the Ramps API expects instead of maintaining duplicate copies of the rule (#9801)
  • Lowercases eip155 asset ids, matching the namespace case-insensitively, and passes other namespaces through verbatim so case-sensitive references (Solana base58, bitcoin bech32) are preserved.
• Export TERMINAL_ORDER_STATUSES and isTerminalOrderStatus() so consuming clients can share the controller's terminal order status set instead of maintaining duplicate copies. (#9679)

Changed

• Preserve backend provider ranking metadata in RampsService.getProviders and RampsController.getProviders responses. (#9955)
• Bump @metamask/remote-feature-flag-controller from ^5.0.0 to ^6.0.0 (#9945)
• Bump @metamask/remote-feature-flag-controller from ^5.0.0 to ^6.1.0 (#9945, #9980)

Fixed

• providerServesAsset() and getProvidersServingAsset() no longer lowercase non-EVM CAIP-19 asset references when matching a provider's supportedCryptoCurrencies (#9801)
  • Solana base58 and bitcoin bech32 references are case-sensitive, so lowercasing both sides could report a provider as serving an asset it does not serve. EVM ids still match regardless of checksum casing.
