 ### Changed
 
+- Live token balance queries now respect the `confirmations_pay_extended.excludeChainIdsFromInfura` feature flag, skipping the Infura endpoint preference for excluded chains ([#8992](https://github.com/MetaMask/core/pull/8992))
 - Bump `@metamask/assets-controllers` from `^108.3.0` to `^108.4.0` ([#8981](https://github.com/MetaMask/core/pull/8981))
 - Bump `@metamask/assets-controller` from `^8.0.2` to `^8.3.1` ([#8981](https://github.com/MetaMask/core/pull/8981), [#8985](https://github.com/MetaMask/core/pull/8985))
 - Bump `@metamask/remote-feature-flag-controller` from `^4.2.1` to `^4.2.2` ([#8986](https://github.com/MetaMask/core/pull/8986))
