impl TransactionApi

pub fn as_multi_threshold_1( &self, other_signatories: OtherSignatories, call: Call, ) -> StaticPayload<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.

Complexity

O(Z + C) where Z is the length of the call and C its execution weight.

pub fn as_multi( &self, threshold: Threshold, other_signatories: OtherSignatories, maybe_timepoint: MaybeTimepoint, call: Call, max_weight: MaxWeight, ) -> StaticPayload<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.

Complexity

• O(S + Z + Call).
• Up to one balance-reserve or unreserve operation.
• One passthrough operation, one insert, both O(S) where S is the number of signatories. S is capped by MaxSignatories, with weight being proportional.
• One call encode & hash, both of complexity O(Z) where Z is tx-len.
• One encode & hash, both of complexity O(S).
• Up to one binary search and insert (O(logS + S)).
• I/O: 1 read O(S), up to 1 mutate O(S). Up to one remove.
• One event.
• The weight of the call.
• Storage: inserts one item, value size bounded by MaxSignatories, with a deposit taken for its lifetime of DepositBase + threshold * DepositFactor.

pub fn approve_as_multi( &self, threshold: Threshold, other_signatories: OtherSignatories, maybe_timepoint: MaybeTimepoint, call_hash: CallHash, max_weight: MaxWeight, ) -> StaticPayload<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.

Complexity

• O(S).
• Up to one balance-reserve or unreserve operation.
• One passthrough operation, one insert, both O(S) where S is the number of signatories. S is capped by MaxSignatories, with weight being proportional.

pub fn cancel_as_multi( &self, threshold: Threshold, other_signatories: OtherSignatories, timepoint: Timepoint, call_hash: CallHash, ) -> StaticPayload<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.

• O(S).
• Up to one balance-reserve or unreserve operation.
• One passthrough operation, one insert, both O(S) where S is the number of signatories. S is capped by MaxSignatories, with weight being proportional.
• One encode & hash, both of complexity O(S).

• I/O: 1 read O(S), one remove.
• Storage: removes one item.

pub fn poke_deposit( &self, threshold: Threshold, other_signatories: OtherSignatories, call_hash: CallHash, ) -> StaticPayload<PokeDeposit>

Poke the deposit reserved for an existing multisig operation.

The dispatch origin for this call must be Signed and must be the original depositor of the multisig operation.

The transaction fee is waived if the deposit amount has changed.

• threshold: The total number of approvals needed for this multisig.
• other_signatories: The accounts (other than the sender) who are part of the multisig.
• call_hash: The hash of the call this deposit is reserved for.

Emits DepositPoked if successful.
