MultiAgentRawTransaction

Aptos Blockchain Multi-Agent Raw Transaction

public struct MultiAgentRawTransaction 

Properties

rawTransaction

The raw transaction itself

public var rawTransaction: RawTransaction

secondarySigners

The other parties involved

public var secondarySigners: [AccountAddress]

Methods

inner()

Returns the Multi-Agent's raw transaction

public func inner() -> RawTransaction 

Returns

A RawTransaction object

prehash()

Compute the SHA3-256 hash of a string representation of a transaction with data.

public func prehash() throws -> Data 

This function computes the SHA3-256 hash of the string "APTOS::RawTransactionWithData", which serves as a prefix to the transaction data, and returns the result.

Throws

An AptosError object indicating that the conversion from string to Data object has failed.

Returns

A Data object containing the SHA3-256 hash of the string "APTOS:​:​RawTransactionWithData".

keyed()

Serialize and hash a multi-agent raw transaction for signing.

public func keyed() throws -> Data 

This function serializes the multi-agent raw transaction using a Serializer instance, computes the SHA3-256 hash of the serialized transaction concatenated with a prehash, and returns the result.

Throws

An error of type AptosError indicating that the serialization or prehash computation has failed.

Returns

A Data object containing the SHA3-256 hash of the serialized transaction concatenated with a prehash.

sign(_:)

Sign the multi-agent raw transaction using the provided private key.

public func sign(_ key: PrivateKey) throws -> Signature 

This function signs the multi-agent raw transaction using the provided private key and returns the resulting signature.

Parameters

• key: A PrivateKey object to be used for signing the multi-agent raw transaction.
• Returns: A Signature object containing the signature of the multi-agent raw transaction.
• Throws: An error of type Ed25519Error indicating that the signing operation has failed.

verify(_:_:)

Verify the signature of the multi-agent raw transaction using the provided public key.

public func verify(_ key: PublicKey, _ signature: Signature) throws -> Bool 

This function verifies the signature of the multi-agent raw transaction using the provided public key and returns a Boolean value indicating whether the signature is valid or not.

Parameters

• key: A PublicKey object to be used for verifying the signature of the multi-agent raw transaction.
• signature: A Signature object containing the signature to be verified.
• Returns: A Boolean value indicating whether the signature is valid or not.
• Throws: An error of type Ed25519Error indicating that the verification operation has failed.
