Credentials class abstract

Anything that can sign payloads with a private key.

Constructors

Credentials()

Properties

address → EthereumAddress

no setter

hashCode → int

The hash code for this object.

no setter, inherited

isolateSafe → bool

Whether these Credentials are safe to be copied to another isolate and can operate there. If this getter returns true, the client might chose to perform the expensive signing operations on another isolate.

no setter

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

extractAddress() → Future<EthereumAddress>

Loads the ethereum address specified by these credentials.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

sign(Uint8List payload, {int? chainId, bool isEIP1559 = false}) → Future<Uint8List>

Signs the payload with a private key. The output will be like the bytes representation of the eth_sign RPC method, but without the "Ethereum signed message" prefix. The payload parameter contains the raw data, not a hash.

signPersonalMessage(Uint8List payload, {int? chainId}) → Future<Uint8List>

Signs an Ethereum specific signature. This method is equivalent to sign, but with a special prefix so that this method can't be used to sign, for instance, transactions.

signPersonalMessageToUint8List(Uint8List payload, {int? chainId}) → Uint8List

Signs an Ethereum specific signature. This method is equivalent to signToUint8List, but with a special prefix so that this method can't be used to sign, for instance, transactions.

signToEcSignature(Uint8List payload, {int? chainId, bool isEIP1559 = false}) → MsgSignature

Signs the payload with a private key and returns the obtained signature.

signToSignature(Uint8List payload, {int? chainId, bool isEIP1559 = false}) → Future<MsgSignature>

Signs the payload with a private key and returns the obtained signature.

signToUint8List(Uint8List payload, {int? chainId, bool isEIP1559 = false}) → Uint8List

Signs the payload with a private key. The output will be like the bytes representation of the eth_sign RPC method, but without the "Ethereum signed message" prefix. The payload parameter contains the raw data, not a hash.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
