PolymeshTransactionBase
Properties
blockHash
• Optional
blockHash: string
hash of the block where this transaction resides (status: Succeeded
, Failed
)
Defined in
base/PolymeshTransactionBase.ts:106
blockNumber
• Optional
blockNumber: BigNumber
number of the block where this transaction resides (status: Succeeded
, Failed
)
Defined in
base/PolymeshTransactionBase.ts:111
error
• Optional
error: PolymeshError
stores errors thrown while running the transaction (status: Failed
, Aborted
)
Defined in
base/PolymeshTransactionBase.ts:86
multiSig
• multiSig: null
| MultiSig
This will be set if the signingAddress is a MultiSig signer, otherwise null
When set it indicates the transaction will be wrapped as a proposal for the MultiSig,
meaning .runAsProposal
should be used instead of .run
Defined in
base/PolymeshTransactionBase.ts:119
receipt
• Optional
receipt: ISubmittableResult
stores the transaction receipt (if successful)
Defined in
base/PolymeshTransactionBase.ts:91
status
• status: TransactionStatus
= TransactionStatus.Idle
current status of the transaction
Defined in
base/PolymeshTransactionBase.ts:81
txHash
• Optional
txHash: string
transaction hash (status: Running
, Succeeded
, Failed
)
Defined in
base/PolymeshTransactionBase.ts:96
txIndex
• Optional
txIndex: BigNumber
transaction index within its block (status: Succeeded
, Failed
)
Defined in
base/PolymeshTransactionBase.ts:101
Accessors
isSuccess
• get
isSuccess(): boolean
returns true if transaction has completed successfully
Returns
boolean
Defined in
base/PolymeshTransactionBase.ts:903
result
• get
result(): TransformedReturnValue
returns the transaction result - this is the same value as the Promise run returns
Returns
TransformedReturnValue
Note
it is generally preferable to await
the Promise
returned by transaction.run() instead of reading this property
Throws
if the transaction.isSuccess property is false — be sure to check that before accessing!
Defined in
base/PolymeshTransactionBase.ts:819
Methods
getProtocolFees
▸ Abstract
getProtocolFees(): Promise
<BigNumber
>
Return this transaction's protocol fees. These are extra fees charged for specific operations on the chain. Not to be confused with network fees (which depend on the complexity of the operation), protocol fees are set by governance and/or chain upgrades
Returns
Promise
<BigNumber
>
Defined in
base/PolymeshTransactionBase.ts:745
getTotalFees
▸ getTotalFees(): Promise
<PayingAccountFees
>
Retrieve a breakdown of the fees required to run this transaction, as well as the Account responsible for paying them
Returns
Promise
<PayingAccountFees
>
Note
these values might be inaccurate if the transaction is run at a later time. This can be due to a governance vote or other chain related factors (like modifications to a specific subsidizer relationship or a chain upgrade)
Defined in
base/PolymeshTransactionBase.ts:537
onProcessedByMiddleware
▸ onProcessedByMiddleware(listener
): UnsubCallback
Subscribe to the results of this transaction being processed by the indexing service (and as such, available to the middleware)
Parameters
Name | Type | Description |
---|---|---|
listener | (err? : PolymeshError ) => void | callback function that will be called whenever the middleware is updated with the latest data. If there is an error (timeout or middleware offline) it will be passed to this callback |
Returns
unsubscribe function
Note
this event will be fired even if the queue fails
Throws
if the middleware wasn't enabled when instantiating the SDK client
Defined in
base/PolymeshTransactionBase.ts:577
onStatusChange
▸ onStatusChange(listener
): UnsubCallback
Subscribe to status changes
Parameters
Name | Type | Description |
---|---|---|
listener | (transaction : GenericPolymeshTransaction <ReturnValue , TransformedReturnValue >) => void | callback function that will be called whenever the status changes |
Returns
unsubscribe function
Defined in
base/PolymeshTransactionBase.ts:519
run
▸ run(): Promise
<TransformedReturnValue
>
Run the transaction, update its status and return a result if applicable. Certain transactions create Entities on the blockchain, and those Entities are returned for convenience. For example, when running a transaction that creates an Asset, the Asset itself is returned
Returns
Promise
<TransformedReturnValue
>
Defined in
base/PolymeshTransactionBase.ts:270
runAsProposal
▸ runAsProposal(): Promise
<MultiSigProposal
>
Run the transaction as a multiSig proposal
Returns
Promise
<MultiSigProposal
>
Defined in
base/PolymeshTransactionBase.ts:228
supportsSubsidy
▸ Abstract
supportsSubsidy(): boolean
Return whether the transaction can be subsidized. If the result is false AND the caller is being subsidized by a third party, the transaction can't be executed and trying to do so will result in an error
Returns
boolean
Note
this depends on the type of transaction itself (e.g. staking.bond
can't be subsidized, but asset.createAsset
can)
Defined in
base/PolymeshTransactionBase.ts:715
toSignablePayload
▸ toSignablePayload(metadata?
): Promise
<TransactionPayload
>
Returns a representation intended for offline signers.
Parameters
Name | Type |
---|---|
metadata | Record <string , string > |
Returns
Promise
<TransactionPayload
>
Note
Usually .run()
should be preferred due to is simplicity.
Note
When using this method, details like account nonces, and transaction mortality require extra consideration. Generating a payload for offline sign implies asynchronicity. If using this API, be sure each procedure is created with the correct nonce, accounting for in flight transactions, and the lifetime is sufficient.
