Multisig class

Main class for managing multisig operations on a Substrate-based blockchain.

This class provides methods for creating, funding, and managing multisig accounts, as well as approving and executing multisig transactions. It handles the complete lifecycle of multisig operations including initiating transfers, collecting approvals, and executing transactions when the threshold is met.

Example:

final multisig = Multisig(
  provider: provider,
  chainInfo: chainInfo,
  multisigAccount: multisigAccount,
);

// Fund the multisig account
await multisig.createAndFundMultisig(
  fundingAmount: BigInt.from(1000000000000),
  depositorAddress: alice.address,
  signingCallback: alice.sign,
);

Constructors

Methods

approveAsMulti({required String approverAddress, required SigningCallback signingCallback, required Uint8List callData, int eraPeriod = 64, BigInt? tip, int? nonce, Weight? maxWeight}) → Future<MultisigResponse>

Approves a pending multisig transaction (non-final approval).

asMulti({required Uint8List callData, required String approverAddress, required SigningCallback signingCallback, int eraPeriod = 64, BigInt? tip, int? nonce, Weight? maxWeight}) → Future<MultisigResponse>

Submits the final approval and executes the multisig transaction.

cancel({required String signerAddress, required SigningCallback signingCallback, required Uint8List callHash, int eraPeriod = 64, int? nonce}) → Future<Uint8List>

Cancels a pending multisig transaction and refunds the deposit.

createAndFundMultisig({required BigInt fundingAmount, required String depositorAddress, required SigningCallback signingCallback, int eraPeriod = 64, BigInt? tip}) → Future<MultisigResponse>

Creates and funds a multisig account by transferring the specified amount from the depositor's account.

createCallData({required String recipientAddress, required BigInt transferAmount, bool keepAlive = true}) → Uint8List

Creates SCALE-encoded call data for a balance transfer operation.

initiateTransfer({required String senderAddress, required SigningCallback signingCallback, required String recipientAddress, required BigInt transferAmount, bool keepAlive = true, int eraPeriod = 64, BigInt? tip, int? nonce, Weight? maxWeight}) → Future<MultisigResponse>

Initiates a transfer from the multisig account by creating the first approval.

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

inherited

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
