Syntax

public sealed class EvmTransactionInput

Properties

ChainId

The corresponding Chain identifier for the network that this transaction is being submitted to.

Declaration

public BigInteger ChainId { get; set; }

Property Value

Type	Description
BigInteger

EvmNonce

The current EVM Nonce associated with the account that will sign this transaction.

Declaration

public long EvmNonce { get; set; }

Property Value

Type	Description
long

GasLimit

The maximum amount of gas, in gas units, that the paying account is willing to pay to execute the transaction.

Declaration

public long GasLimit { get; set; }

Property Value

Type	Description
long

GasPrice

The gas price the signing account is willing to pay for computational resources to execute the transaction.

Declaration

public long GasPrice { get; set; }

Property Value

Type	Description
long

MethodName

Optional method name to call on the contract, if this is a contract call. This value must be specified if the transaction is a contract call having any values in the MethodParameters array.

Declaration

public string? MethodName { get; set; }

Property Value

Type	Description
string

MethodParameters

Optional method parameters to pass to the contract, if this is a contract call.

Declaration

public object[]? MethodParameters { get; set; }

Property Value

Type	Description
object[]

ToEvmAddress

The recipient of the transaction, which may be a contract or another Hedera account.

Declaration

public EvmAddress ToEvmAddress { get; set; }

Property Value

Type	Description
EvmAddress

Remarks

Going forward, this should be the EVM address of the account as identified by the mirror node. It may be a long zero EVM address or an ECDSA alias address. To avoid potential compatibility issues, it is recommended to use the EVM address for the target account or contract as identified by the mirror node, not just assume the long zero address is the correct address.

ValueInTinybars

The amount of HBAR to transfer to the recipient of the transaction.

Declaration

public long ValueInTinybars { get; set; }

Property Value

Type	Description
long

Methods

RlpEncode(Signatory)

Generates an RLP encoded byte array representing the transaction input values, including the signature if the Signatory is provided.

Declaration

public ReadOnlyMemory<byte> RlpEncode(Signatory signatory)

Parameters

Type	Name	Description
Signatory	signatory	Signatory (Private Key) that will sign the transaction, it must be a single ECDSA key that corresponds to the EVM address of the account paying for the transaction.

Returns

Type	Description
ReadOnlyMemory<byte>	An array of bytes representing the transaction in EVM RLP encoding.
