@nvonpentz i did some tests. I think this could be related to https://github.com/brave/brave-browser/issues/35697. However, this time, we can trigger asset discovery by calling WalletService.discoverAssetsOnAllSupportedChains but core only returns some assets not all assets via WalletService.onDiscoverAssetsCompleted callback.
