// TODO: We may have a fetchTokenHistory in future, but Fulcrum does not currently support indexing tokens.
//       There are actually a few functional discrepancies with the adapters: different adapters grant different capabilities.
//       For example, Chaingraph can fetch token and address history. But BCHN P2P network cannot even fetch address history.
//       We might want to handle this by having multiple BlockchainInterfaces (e.g. IBlockchainAddressSubscriptions) that describe capabilities.
//       But we should return to that later.
