Syntax

public sealed class Transaction : IEquatable<Transaction>, ITransaction, IUnsignedTx, ITxInvoice, ITxSigningMetadata

Constructors

Transaction(IUnsignedTx, ImmutableArray<Byte>)

Creates a new Transaction instance by verifying a signature of an unsignedTx.

Declaration

public Transaction(IUnsignedTx unsignedTx, ImmutableArray<byte> signature)

Parameters

Type	Name	Description
IUnsignedTx	unsignedTx	The IUnsignedTx instance to combine with signature.
ImmutableArray<System.Byte>	signature	The signature to combine with unsignedTx.

Exceptions

Type	Condition
InvalidTxSignatureException	Thrown when the given signature is not valid for unsignedTx.

ITransaction

Transaction(IUnsignedTx, PrivateKey)

Creates a new Transaction instance by signing an unsignedTx with a privateKey.

Declaration

public Transaction(IUnsignedTx unsignedTx, PrivateKey privateKey)

Parameters

Type	Name	Description
IUnsignedTx	unsignedTx	The IUnsignedTx instance to sign.
PrivateKey	privateKey	The private key to sign unsignedTx with.

ITransaction

Properties

Actions

A list of s. These are executed in the order. This can be empty, but cannot be null.

Declaration

public TxActionList Actions { get; }

Property Value

Type	Description
TxActionList

See Also

ITransaction

GasLimit

The limit on the total amount of gas that the Transaction can use.

If null, gas processing is entirely bypassed. The parity of null-ness is always the same as that of MaxGasPrice.

If not null, this value cannot be negative.

Declaration

public long? GasLimit { get; }

Property Value

Type	Description
System.Nullable<System.Int64>

See Also

GasLimit

GenesisHash

A BlockHash value of the genesis which this transaction is made from. This can be null iff the transaction is contained in the genesis block.

Declaration

public BlockHash? GenesisHash { get; }

Property Value

Type	Description
System.Nullable<BlockHash>

See Also

ITransaction

Id

A unique identifier derived from this Transaction's content.

For more characteristics, see TxId type.

Declaration

public TxId Id { get; }

Property Value

Type	Description
TxId

See Also

TxId

MaxGasPrice

The maximum amount of FungibleAssetValue that the Transaction's author is willing to pay per gas for the Transaction.

If null, gas processing is entirely bypassed. The parity of null-ness is always the same as that of GasLimit.

If not null, this value cannot be negative.

Declaration

public FungibleAssetValue? MaxGasPrice { get; }

Property Value

Type	Description
System.Nullable<FungibleAssetValue>

See Also

GasLimit

Nonce

The number of previous Transactions committed by the Signer of this transaction. This nonce is used for preventing replay attack.

Declaration

public long Nonce { get; }

Property Value

Type	Description
System.Int64

See Also

ITransaction

PublicKey

A PublicKey of the account who signs this transaction. The Signer address is always corresponding to this for each transaction. This cannot be null.

Declaration

public PublicKey PublicKey { get; }

Property Value

Type	Description
PublicKey

See Also

ITransaction

Signature

A digital signature of the content of this Transaction. This is signed by the account who corresponds to PublicKey. This cannot be null.

Declaration

public byte[] Signature { get; }

Property Value

Type	Description
System.Byte[]	A new array of this transaction's signature. Changing a returned array does not affect the internal state of this Transaction object.

Remarks

Although this cannot be null, it can be an empty array if the transaction is not signed yet.

See Also

ITransaction

Signer

A PublicKey of the account who signs this transaction. This is derived from the PublicKey.

Declaration

public Address Signer { get; }

Property Value

Type	Description
Address

See Also

ITransaction

Timestamp

The time this transaction is created and signed.

Declaration

public DateTimeOffset Timestamp { get; }

Property Value

Type	Description
DateTimeOffset

See Also

ITransaction

UpdatedAddresses

A deprecated property which was used as an approximated list of addresses whose states would be affected by actions in this transaction.

This is no longer officially supported in the sense that a Transaction cannot be created with a non-empty set of Addresses through normal means (i.e. using intended APIs).

It is still possible to create a Transaction through other means, such as creating a payload directly by assigning appropriate values and signing an "unsigned transaction". This is not recommended.

Declaration

public IImmutableSet<Address> UpdatedAddresses { get; }

Property Value

Type	Description
IImmutableSet<Address>

ITransaction

Methods

Create(Int64, PrivateKey, Nullable<BlockHash>, IEnumerable<IValue>, Nullable<FungibleAssetValue>, Nullable<Int64>, Nullable<DateTimeOffset>)

A façade factory to create a new Transaction. It automatically fills the following values from:

Property	Parameter the filled value derived from
Signer	privateKey
PublicKey	privateKey
UpdatedAddresses	actions and updatedAddresses

Note that the privateKey in itself is not included in the created Transaction.

Declaration

public static Transaction Create(long nonce, PrivateKey privateKey, BlockHash? genesisHash, IEnumerable<IValue> actions, FungibleAssetValue? maxGasPrice = null, long? gasLimit = null, DateTimeOffset? timestamp = null)

Parameters

Type	Name	Description
System.Int64	nonce	The number of previous Transactions committed by the Signer of this transaction. This goes to the Nonce property.
PrivateKey	privateKey	A PrivateKey of the account who creates and signs a new transaction. This key is used to fill the Signer, PublicKey, and Signature properties, but this in itself is not included in the transaction.
System.Nullable<BlockHash>	genesisHash	A value of the genesis which this Transaction is made from. This can be null iff the transaction is contained in the genesis block.
IEnumerable<IValue>	actions	A list of user-defined custom actions to include. This can be empty, but cannot be null. This goes to the Actions property.
System.Nullable<FungibleAssetValue>	maxGasPrice	The maximum gas price this transaction can pay fee.
System.Nullable<System.Int64>	gasLimit	The maximum amount of gas this transaction can consume.
System.Nullable<DateTimeOffset>	timestamp	The time this Transaction is created and signed. This goes to the Timestamp property. If null (which is default) is passed this will be the current time.

Returns

Type	Description
Transaction	A created new Transaction signed by the given privateKey.

ITransaction

Deserialize(Byte[])

Decodes a Transaction's Bencodex representation.

Declaration

public static Transaction Deserialize(byte[] bytes)

Parameters

Type	Name	Description
System.Byte[]	bytes	A Bencodex representation of a Transaction.

Returns

Type	Description
Transaction	A decoded Transaction object.

Exceptions

Type	Condition
InvalidTxSignatureException	Thrown when its Signature is invalid or not signed by the account who corresponds to PublicKey.
