## Introduction | ||
|
||
Most of the time, simply testing your smart contract isn't enough. To manipulate the state of the Aztec blockchain, as well as test for specific reverts and events, the sandbox is shipped with a set of cheatcodes. |

The start is a little weird. It is mainly to help you in the testing that we want to provide a bit of cheat-codes.

When mentioning specific reverts and such, we should probably have examples with that 👀 .
const value = await cc.l2.loadPublic(contract, 1n) // current_value is stored in slot 1 | ||
``` | ||

Think it would be neat to flip the ordering of computeSlotInMap
and loadPublic
, mainly as we could then very easily show using the computed slot for reading balances or similar. Just to carve it in neon what people can use it for etc.

Separately, the example is made with private storage, which you cannot access from cheatcodes etc. Think using public storage would be better, and then it can be bundled with the loadPublic
as mentioned.

Cheatcodes allow you to change the time of the L2 block, load certain state or more easily manipulate L1 instead of having to write dedicated RPC calls to anvil. |

This has just made me think, should we make the cheat codes agnostic of hardhat / anvil

hmm aztec uses anvil within the sandbox though

Think anvil
will also accept the hardhat naming and is just used as aliases, so if we use the hardhat ones, it might cover both more easily.

In case we like the `.eth` and `.aztec` variation over `.l1` and `.l2` in cheatcodes! This would get merged into my docs pr #1585

#### Description | ||
Sets the timestamp (unix format in seconds) for the next mined block on Ethereum. | ||
Remember that timestamp can only be set in the future and not in the past. |

should get better highlighting using `ts rather than js
These are cheatcodes exposed from anvil/hardhat conveniently wrapped for ease of use in the Sandbox. | ||

annotate `ts

noir snippets can be annotated rust for better results

Overall great content, however noir snippets can be annotated with rust, the ones currently js should be ts to get better highlighting and solidity ones can be separated rather than inline commented and annotated with
solidity
``` | ||
/// contract LeetContract { | ||
/// uint256 private leet = 1337; // slot 0 | ||
/// } | ||
|
||
const leetContractAddress = EthAddress.fromString('0x1234...'); | ||
await cc.eth.store(leetContractAddress, BigInt(0), BigInt(1000)); | ||
const value = await cc.eth.load(leetContractAddress, BigInt(0)); | ||
console.log(value); // 1000 | ||
``` |

contract LeetContract {
uint256 private leet = 1337; // slot 0
}
const leetContractAddress = EthAddress.fromString('0x1234...');
await cc.eth.store(leetContractAddress, BigInt(0), BigInt(1000));
const value = await cc.eth.load(leetContractAddress, BigInt(0));
console.log(value); // 1000
Solidity blocks can be annotated with solidity, they arent perfect in docusaurus but it does offer some highlighting.
In case we like the `.eth` and `.aztec` variation over `.l1` and `.l2` in cheatcodes! This would get merged into my docs pr #1585

#### Description | ||
Loads the value stored at the given slot in the public storage of the given contract. | ||
|
||
Note: One Field element occupies a storage slot. So structs with multiple field elements won't fit in a single slot. So using loadPublic would only load a part of the struct (depending on the size of the attributes within it). |

Note: One Field element occupies a storage slot. Hence, structs with multiple field elements will be spread over multiple slots, rather they will be spread over multiple sequential slots. Using loadPublic will only load a single field of the struct (depending on the size of the attributes within it). |
Id reword this slightly

#### Description | ||
Dumps the current Ethereum chain state to a file. | ||
Stores a hex string representing the complete state of the chain in a file with the provided path. Can be re-imported into a fresh/restarted instance of Anvil to reattain the same state. | ||
When combined with `loadChainState()` cheatcode, it can be let you easily import the current state of mainnet into the Anvil instance of the sandbox, to use Uniswap for example. |

The uniswap example here is really specific to our testing case and probably confusing without context. Lets drop it, people looking for this feature likely have in mind a specific use case

The wording is a little weird here, it can be let you
and it might not be the current
state. Maybe fine to point to the other cheatcode and say use in combination.

To be used in combination with `loadChainState()` |
