XChainJS API UTXO providers Interface

A specification for a generalised interface for api providers, to be used by XChainJS implementations. The providers should not have any functionality to generate a key, instead, the xchain-crypto library should be used to ensure cross-chain compatible keystores are handled. The providers is only ever passed a master BIP39 phrase, from which a temporary key and address is decoded.

  getTransactions(params: TxHistoryParams): Promise<TxsPage>
  getTransactionData(txId: string, assetAddress?: Address): Promise<Tx>
}
