# TxResult.txGasUsed

Returns the gas a receipt reports: `max(totalGasSpent - refunded, floorGas)`.

This is the value a transaction is charged for, which is neither `totalGasSpent` (pre-refund) nor a plain subtraction (the EIP-7623 floor can absorb the refund).

## Imports

:::code-group
```ts [Named]
import { TxResult } from 'ox/evm'
```

```ts [Entrypoint]
import * as TxResult from 'ox/evm/TxResult'
```
:::

## Examples

```ts twoslash
// @noErrors
import { Evm, TxResult } from 'ox/evm'

const result = Evm.callTx(evm, transaction)
TxResult.txGasUsed(result)
// @log: 21000n
```

* **Type:** `bigint`

State gas consumed per EIP-8037. Zero when EIP-8037 is disabled.

#### result.status

* **Type:** `boolean`

Whether execution succeeded.

#### result.stop

* **Type:** `"stop" | "return" | "selfDestruct" | "revert" | "callTooDeep" | "outOfFunds" | "createInitCodeStartingEF00" | "invalidEofInitCode" | "invalidExtDelegateCallTarget" | "outOfGas" | ... 22 more ... | "invalidImmediateEncoding"`
