Construction

initTx Source #

Arguments

:: NetworkId
-> TxIn	Seed input.
-> [OnChainId]	Verification key hashes of all participants.
-> HeadParameters
-> Tx

Create the init transaction from some HeadParameters and a single TxIn which will be used as unique parameter for minting NFTs.

mkHeadOutput :: NetworkId -> PolicyId -> TxOutDatum ctx -> TxOut ctx Source #

mkHeadOutputInitial :: NetworkId -> TxIn -> HeadParameters -> TxOut CtxTx Source #

mkInitialOutput :: NetworkId -> TxIn -> OnChainId -> TxOut CtxTx Source #

Observation

data InitObservation Source #

Data which can be observed from an initTx.

observeInitTx :: Tx -> Either NotAnInitReason InitObservation Source #

Identify a init tx by checking the output value for holding tokens that are valid head tokens (checked by seed + policy).
