### Signature

```solidity
function store(address account, bytes32 slot, bytes32 value) external;
```

### Description

Stores the value `value` in storage slot `slot` on account `account`.

### Parameters

| Parameter | Type      | Description                              |
|-----------|-----------|------------------------------------------|
| `account` | `address` | The account whose storage will be modified|
| `slot`    | `bytes32` | The storage slot to write to             |
| `value`   | `bytes32` | The value to store                       |

### Examples

:::code-group
```solidity [test/Store.t.sol]
function testStore() public {
    vm.store(address(leetContract), bytes32(uint256(0)), bytes32(uint256(31337)));
    bytes32 leet = vm.load(address(leetContract), bytes32(uint256(0)));
    assertEq(uint256(leet), 31337);
}
```

```solidity [src/LeetContract.sol]
contract LeetContract {
    uint256 private leet = 1337; // slot 0
}
```

### Gotchas

:::warning
You must know the exact storage slot layout of the contract. Solidity uses complex packing rules for storage, especially for mappings and dynamic arrays. Use `forge inspect` or the [Std Storage](/reference/forge-std/std-storage) library to find storage slots.
