Electrum/Fulcrum already covers everything the backend needs for Bitcoin and Litecoin — balance, UTXOs, history, tip, verbose tx, fee estimation, and broadcast (blockchain.transaction.broadcast). A self-hosted Fulcrum relays broadcasts to its own backing node, so a separate Bitcoin Core RPC path buys nothing in the self-host model while adding the bitcoincore-rpc + bitcoin + secp256k1 + jsonrpc dependency tree and a duplicate broadcast surface. - Remove the `bitcoincore-rpc` dependency (and its transitive tree). - Slim `UtxoConfig` to pure Electrum config: drop use_local_node / rpc_url / rpc_user / rpc_pass; keep network + electrum_primary + electrum_fallbacks. A future LTC-MWEB or direct-node provider is a distinct capability (MWEB uses a scan-key model, not canonical scriptPubKeys) and would slot in at the provider seam rather than extending this client — so nothing is foreclosed by keeping the surface minimal now.
