| Property      | Type                                                 | Description                                                                                                                                                                                                                                        | Inherited from    |
| :------------ | :--------------------------------------------------- | :------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | :---------------- |
| `accessList?` | [`AccessList`](/sdk/content/type-aliases/AccessList) | The [EIP-2930](https://eips.ethereum.org/EIPS/eip-2930) access list. Storage slots included in the access list<br />are warmed by pre-loading them, so their initial cost to fetch is guaranteed, but then each additional access is<br />cheaper. | `Omit.accessList` |
| `blockTag?`   | [`BlockTag`](/sdk/content/type-aliases/BlockTag)     | When using `call` or `estimateGas`, this allows a specific block to be queried. Many backends do not support this<br />and when unsupported errors are silently squelched and `"latest"` is used.                                                  | `Omit.blockTag`   |
| `chainId?`    | `bigint`                                             | The chain ID for the network this transaction is valid on.                                                                                                                                                                                         | `Omit.chainId`    |
| `customData?` | `any`                                                | A custom object, which can be passed along for network-specific values.                                                                                                                                                                            | `Omit.customData` |
