getBalanceBreakdown method
The owner's coinType balance split into coin-object vs address-balance
sources — needed to resolve CoinWithBalance intents that may draw from
the address balance. Transports without address-balance support (e.g.
JSON-RPC) throw; the resolver only reaches this on the gRPC path.
Implementation
@override
Future<CoinBalanceBreakdown> getBalanceBreakdown(
String owner,
String coinType,
) async =>
throw UnimplementedError(
'Address-balance breakdown is not available over JSON-RPC; use the '
'gRPC client for CoinWithBalance resolution from address balances.');
