refactor: make trending token query params extensible

packages/assets-controllers/CHANGELOG.md

@@ -7,8 +7,15 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 
 ## [Unreleased]
 
+### Added
+
+- Export new type `TrendingTokensQueryParams` for extensible trending token query parameters ([#8729](https://github.com/MetaMask/core/pull/8729))
+
 ### Changed
 
+- **BREAKING:** `getTrendingTokens` now accepts `sort` instead of `sortBy` to match the API parameter name ([#8729](https://github.com/MetaMask/core/pull/8729))
+- `getTrendingTokens` and `getTrendingTokensURL` now accept arbitrary query parameters via an index signature on `TrendingTokensQueryParams`, allowing new API parameters to pass through without a core release ([#8729](https://github.com/MetaMask/core/pull/8729))
+
 - Bump `@metamask/account-tree-controller` from `^7.2.0` to `^7.3.0` ([#8722](https://github.com/MetaMask/core/pull/8722))
 - Bump `@metamask/keyring-controller` from `^25.4.0` to `^25.5.0` ([#8722](https://github.com/MetaMask/core/pull/8722))
 - Bump `@metamask/multichain-account-service` from `^8.0.1` to `^9.0.0` ([#8722](https://github.com/MetaMask/core/pull/8722))
