Submitter¶

::: {.module} Cardano.Node.Client.Submitter :::

Protocol-agnostic interface for submitting signed transactions. ConwayTx is the package's alias for Tx TopTx ConwayEra (Cardano.Node.Client.Ledger).

data SubmitResult
    = Submitted !TxId       -- accepted into the mempool
    | Rejected !ByteString  -- rejection reason (UTF-8)

newtype Submitter m = Submitter
    { submitTx :: ConwayTx -> m SubmitResult
    }

Constructors¶

Function	Module	Transport
`mkN2CSubmitter`	`Cardano.Node.Client.N2C.Submitter`	Unix socket (N2C)

The N2C submitter wraps the ledger ConwayTx into a consensus GenTx Block before submission and serialises any rejection reason to a ByteString.

Usage¶

import Cardano.Node.Client.N2C.Submitter (mkN2CSubmitter)

let submitter = mkN2CSubmitter ltxsChannel

result <- submitTx submitter signedTx
case result of
    Submitted txId  -> putStrLn $ "OK: " <> show txId
    Rejected reason -> putStrLn $ "FAIL: " <> show reason
