***

### `Optional` error

• **error**? : [*PolymeshError*](https://developers.polymath.network/polymesh-sdk-api-reference/classes/polymesherror)

*Defined in* [*src/base/PolymeshTransactionBase.ts:32*](https://github.com/PolymeshAssociation/polymesh-sdk/blob/46845947/src/base/PolymeshTransactionBase.ts#L32)

stores errors thrown while running the transaction (status: `Failed`, `Aborted`)

***

### isCritical

• **isCritical**: *boolean*

*Defined in* [*src/base/PolymeshTransactionBase.ts:57*](https://github.com/PolymeshAssociation/polymesh-sdk/blob/46845947/src/base/PolymeshTransactionBase.ts#L57)

whether this transaction failing makes the entire transaction queue fail or not

***

### `Optional` receipt

• **receipt**? : *ISubmittableResult*

*Defined in* [*src/base/PolymeshTransactionBase.ts:37*](https://github.com/PolymeshAssociation/polymesh-sdk/blob/46845947/src/base/PolymeshTransactionBase.ts#L37)

stores the transaction receipt (if successful)

***

### status

• **status**: [*TransactionStatus*](https://github.com/PolymeshAssociation/polymesh-sdk/blob/docs/v14/docs/enums/transactionstatus.md) = TransactionStatus.Idle

*Defined in* [*src/base/PolymeshTransactionBase.ts:27*](https://github.com/PolymeshAssociation/polymesh-sdk/blob/46845947/src/base/PolymeshTransactionBase.ts#L27)

current status of the transaction

***

### `Optional` txHash

• **txHash**? : *undefined | string*

*Defined in* [*src/base/PolymeshTransactionBase.ts:42*](https://github.com/PolymeshAssociation/polymesh-sdk/blob/46845947/src/base/PolymeshTransactionBase.ts#L42)

## Methods

### getFees

▸ **getFees**(): *Promise‹*[*Fees*](https://github.com/PolymeshAssociation/polymesh-sdk/blob/docs/v14/docs/interfaces/fees.md) *| null›*

*Defined in* [*src/base/PolymeshTransactionBase.ts:337*](https://github.com/PolymeshAssociation/polymesh-sdk/blob/46845947/src/base/PolymeshTransactionBase.ts#L337)

Get all (protocol and gas) fees associated with this transaction. Returns null if the transaction is not ready yet (this can happen if it depends on the execution of a previous transaction in the queue)

**`note`** this value might change if the transaction is run at a later time. This can be due to a governance vote

**Returns:** *Promise‹*[*Fees*](https://github.com/PolymeshAssociation/polymesh-sdk/blob/docs/v14/docs/interfaces/fees.md) *| null›*

***

### getPayingAccount

▸ **getPayingAccount**(): *Promise‹*[*PayingAccount*](https://github.com/PolymeshAssociation/polymesh-sdk/blob/docs/v14/docs/interfaces/payingaccount.md) *| null›*

*Defined in* [*src/base/PolymeshTransactionBase.ts:295*](https://github.com/PolymeshAssociation/polymesh-sdk/blob/46845947/src/base/PolymeshTransactionBase.ts#L295)

Retrieve the Account that would pay fees for the transaction if it was run at this moment, as well as the total amount that can be charged to it (allowance). A null allowance means that there is no limit to that amount

A null return value signifies that the caller Account would pay the fees

**`note`** this value might change if, before running the transaction, the caller Account enters (or leaves) a subsidizer relationship

**Returns:** *Promise‹*[*PayingAccount*](https://github.com/PolymeshAssociation/polymesh-sdk/blob/docs/v14/docs/interfaces/payingaccount.md) *| null›*

***

### onStatusChange

▸ **onStatusChange**(`listener`: function): *function*

*Defined in* [*src/base/PolymeshTransactionBase.ts:278*](https://github.com/PolymeshAssociation/polymesh-sdk/blob/46845947/src/base/PolymeshTransactionBase.ts#L278)

Subscribe to status changes

**Parameters:**

▪ **listener**: *function*

callback function that will be called whenever the status changes

▸ (`transaction`: this): *void*

**Parameters:**

| Name          | Type |
| ------------- | ---- |
| `transaction` | this |

**Returns:** *function*

unsubscribe function

▸ (): *void*

***

### run

▸ **run**(): *Promise‹void›*

*Defined in* [*src/base/PolymeshTransactionBase.ts:130*](https://github.com/PolymeshAssociation/polymesh-sdk/blob/46845947/src/base/PolymeshTransactionBase.ts#L130)

Run the transaction and update its status

**Returns:** *Promise‹void›*

***

### `Abstract` supportsSubsidy

▸ **supportsSubsidy**(): *boolean*

*Defined in* [*src/base/PolymeshTransactionBase.ts:393*](https://github.com/PolymeshAssociation/polymesh-sdk/blob/46845947/src/base/PolymeshTransactionBase.ts#L393)

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

**`note`** this depends on the type of transaction itself (i.e. `staking.bond` can't be subsidized, but `asset.createAsset` can)

**Returns:** *boolean*
