PTxInfo

info

The modifications in PTxInfo from V2 version are highlighted.

It includes all the information (details about inputs, outputs, fees, minting, certificates, and various associated data) about a transaction in which the script is included.

Definition:

export const PTxInfo = pstruct({
    PTxInfo: {
        inputs: list( PTxInInfo.type ),
        refInputs: list( PTxInInfo.type ),
        outputs: list( PTxOut.type ),
        fee:  int, // lovelaces
        /** mint has no lovelaces entry */
        mint: PValue.type,
        certificates: list( PCertificate.type ),
        withdrawals: map( PCredential.type, int ),
        interval: PPOSIXTimeRange.type,
        signatories: list( PPubKeyHash.type ),
        redeemers: map( PScriptPurpose.type, data ),
        datums: map( PDatumHash.type, data ),
        id: PTxId.type,
        votes: map( PVoter.type, map( PTxOutRef.type, PVote.type ) ),
        proposalProcedures: list( PProposalProcedure.type ),
        currentTreasury: PMaybe( int ).type,
        treasuryDonation: PMaybe( int ).type,
    }
});

Values implements all the properties defined on the TermList utility term.

inputs​

type: list( PTxInInfo.type )

elements's type:

refInputs​

type: list( PTxInInfo.type )

elements's type:

outputs​

List of transaction outputs. Each output represents a new UTXO created by the transaction.

type: list( PTxOut.type )

elements's type: PTxOut

fee​

Transaction fee specified in lovelaces

type: TermInt

mint​

Includes all tokens minted/burned in the transaction.

type: PValue.type

ADA entry

Map of votes cast in the transaction

type: map( PVoter.type, map( PTxOutRef.type, PVote.type ) )

elements's types:
