Multisig

Calls

approveAsMulti

Register approval for a dispatch to be made from a deterministic composite account if approved by a total of threshold - 1 of other_signatories.

Payment: DepositBase will be reserved if this is the first approval, plus threshold times DepositFactor. It is returned once this dispatch happens or is cancelled.

The dispatch origin for this call must be Signed.

threshold: The total number of approvals for this dispatch before it is executed.
other_signatories: The accounts (other than the sender) who can approve this dispatch. May not be empty.
maybe_timepoint: If this is the first approval, then this must be None. If it is not the first approval, then it must be Some, with the timepoint (block number and transaction index) of the first approval transaction.
call_hash: The hash of the call to be executed.

NOTE: If this is the final approval, you will want to use as_multi instead.

Namespace

api.tx.multisig.approveAsMulti

Type

function approveAsMulti(
  threshold: u16,
  other_signatories: Vec<SeedPrimitivesSignatureAccountId20>,
  maybe_timepoint: Option<PalletMultisigTimepoint>,
  call_hash: [u8;32],
  max_weight: WeightV1
)

asMulti

Register approval for a dispatch to be made from a deterministic composite account if approved by a total of threshold - 1 of other_signatories.

If there are enough, then dispatch the call.

Payment: DepositBase will be reserved if this is the first approval, plus threshold times DepositFactor. It is returned once this dispatch happens or is cancelled.

The dispatch origin for this call must be Signed.

threshold: The total number of approvals for this dispatch before it is executed.
other_signatories: The accounts (other than the sender) who can approve this dispatch. May not be empty.
maybe_timepoint: If this is the first approval, then this must be None. If it is not the first approval, then it must be Some, with the timepoint (block number and transaction index) of the first approval transaction.
call: The call to be executed.

NOTE: Unless this is the final approval, you will generally want to use approve_as_multi instead, since it only requires a hash of the call.

Result is equivalent to the dispatched result if threshold is exactly 1. Otherwise on success, result is Ok and the result from the interior call, if it was executed, may be found in the deposited MultisigExecuted event.

Namespace

api.tx.multisig.asMulti

Type

function asMulti(
  threshold: u16,
  other_signatories: Vec<SeedPrimitivesSignatureAccountId20>,

  max_weight: WeightV1
)

asMultiThreshold1

Immediately dispatch a multi-signature call using a single approval from the caller.

The dispatch origin for this call must be Signed.

other_signatories: The accounts (other than the sender) who are part of the multi-signature, but do not participate in the approval process.
call: The call to be executed.

Result is equivalent to the dispatched result.

Namespace

api.tx.multisig.asMultiThreshold1

Type

function asMultiThreshold1(
  other_signatories: Vec<SeedPrimitivesSignatureAccountId20>,
  call: Call
)

cancelAsMulti

Cancel a pre-existing, on-going multisig transaction. Any deposit reserved previously for this operation will be unreserved on success.

The dispatch origin for this call must be Signed.

threshold: The total number of approvals for this dispatch before it is executed.
other_signatories: The accounts (other than the sender) who can approve this dispatch. May not be empty.
timepoint: The timepoint (block number and transaction index) of the first approval transaction for this dispatch.
call_hash: The hash of the call to be executed.
