## So What on Earth Is a Contract Factory?
It is important to understand that Ethereum Virtual Machine (EVM) opcodes can only be called via a smart contract. A contract factory in the context of the EVM refers to a special smart contract that is used to create and deploy other smart contracts on EVM-compatible blockchains using contract creation opcodes (i.e. [`CREATE`](https://www.evm.codes/#f0?fork=shanghai) or [`CREATE2`](https://www.evm.codes/#f5?fork=shanghai)). Using a contract factory provides a flexible and efficient way to deploy and manage smart contracts that share similar functionalities but may have different configurations or settings.
Different approaches can be used to create contracts using a factory contract, and this is exactly what [`CreateX`](./src/CreateX.sol) offers: _a comprehensive range of contract creation functions that are triggered by a smart contract itself_. It is worth emphasising the two differences in the address calculation of the opcodes [`CREATE`](https://www.evm.codes/#f0?fork=shanghai) and [`CREATE2`](https://www.evm.codes/#f5?fork=shanghai) (`||` stands for byte-wise concatenation, `[12:]` refers to the last 20 bytes of a 32-byte expression, and `rlp` is an abbreviation for Ethereum's "Recursive Length Prefix" serialisation scheme):
- [`CREATE`](https://www.evm.codes/#f0?fork=shanghai): `address computedAddress = keccak256(rlpEncode([deployerAddress, deployerNonce]))[12:]`,
- [`CREATE2`](https://www.evm.codes/#f5?fork=shanghai): `address computedAddress = keccak256(0xff||deployerAddress||salt||keccak256(initCode))[12:]`.

Returns the address where a contract will be stored if deployed via _this contract_ (i.e. [`CreateX`](./src/CreateX.sol)) using the [`CREATE`](https://www.evm.codes/#f0?fork=shanghai) opcode. For the specification of the Recursive Length Prefix (RLP) encoding scheme, please refer to p. 19 of the [Ethereum Yellow Paper](https://ethereum.github.io/yellowpaper/paper.pdf) and the [Ethereum Wiki](https://ethereum.org/en/developers/docs/data-structures-and-encoding/rlp/). Based on the [EIP-161](https://github.com/ethereum/EIPs/blob/master/EIPS/eip-161.md) specification, all contract accounts on the Ethereum mainnet are initiated with `nonce = 1`. Thus, the first contract address created by another contract is calculated with a non-zero nonce.

computeCreateAddress(address,uint256)
Returns the address where a contract will be stored if deployed via `deployer` using the [`CREATE`](https://www.evm.codes/#f0?fork=shanghai) opcode.

deployCreate3AndInit(bytes,bytes,tuple(uint256,uint256))
Deploys and initialises a new contract via employing the [`CREATE3`](https://github.com/ethereum/EIPs/pull/3171) pattern (i.e. without an initcode factor) and using the creation bytecode `initCode`, the initialisation code `data`, the struct for the `payable` amounts `values`, `msg.value` as inputs. The salt value is calculated _pseudo-randomly_ using a diverse selection of block and transaction properties. This approach does not guarantee true randomness! In order to save deployment costs, we do not sanity check the `initCode` length. Note that if `values.constructorAmount` is non-zero, `initCode` must have a `payable` constructor, and any excess ether is returned to `msg.sender`.

## Special Features
> [!TIP]
> Note that the separate project [`createXcrunch`](https://github.com/HrikB/createXcrunch) is a [Rust](https://www.rust-lang.org)-based program designed to efficiently find _zero-leading_, _zero-containing_, or _pattern-matching_ deployment addresses, taking into account the subsequent special features of [`CreateX`](./src/CreateX.sol).
### Permissioned Deploy Protection and Cross-Chain Redeploy Protection
The `salt` value implements different safeguarding mechanisms depending on the encoded values in the salt (`||` stands for byte-wise concatenation):
```console
=> salt (32 bytes) = 0xbebebebebebebebebebebebebebebebebebebebe||ff||1212121212121212121212
```
- The first 20 bytes (i.e. `bebebebebebebebebebebebebebebebebebebebe`) may be used to implement a permissioned deploy protection by setting them equal to `msg.sender`,
- The 21st byte (i.e. `ff`) may be used to implement a cross-chain redeploy protection by setting it equal to `0x01`,
- The last random 11 bytes (i.e. `1212121212121212121212`) allow for $2^{88}$ bits of entropy for mining a salt.
The full logic is implemented in the `internal` [`_guard`](./src/CreateX.sol#L873-L912) function:
```solidity
function _guard(bytes32 salt) internal view returns (bytes32 guardedSalt) {
(
SenderBytes senderBytes,
RedeployProtectionFlag redeployProtectionFlag
) = _parseSalt({ salt: salt });
if (
senderBytes == SenderBytes.MsgSender &&
redeployProtectionFlag == RedeployProtectionFlag.True
) {
// Configures a permissioned deploy protection as well as a cross-chain redeploy protection.
guardedSalt = keccak256(abi.encode(msg.sender, block.chainid, salt));
} else if (
senderBytes == SenderBytes.MsgSender &&
redeployProtectionFlag == RedeployProtectionFlag.False
) {
// Configures solely a permissioned deploy protection.
guardedSalt = _efficientHash({
a: bytes32(uint256(uint160(msg.sender))),
b: salt
});
} else if (senderBytes == SenderBytes.MsgSender) {
// Reverts if the 21st byte is greater than `0x01` in order to enforce developer explicitness.
revert InvalidSalt({ emitter: _SELF });
} else if (
senderBytes == SenderBytes.ZeroAddress &&
redeployProtectionFlag == RedeployProtectionFlag.True
) {
// Configures solely a cross-chain redeploy protection. In order to prevent a pseudo-randomly
// generated cross-chain redeploy protection, we enforce the zero address check for the first 20 bytes.
guardedSalt = _efficientHash({ a: bytes32(block.chainid), b: salt });
} else if (
senderBytes == SenderBytes.ZeroAddress &&
redeployProtectionFlag == RedeployProtectionFlag.Unspecified
) {
// Reverts if the 21st byte is greater than `0x01` in order to enforce developer explicitness.
revert InvalidSalt({ emitter: _SELF });
} else {
// For the non-pseudo-random cases, the salt value `salt` is hashed to prevent the safeguard mechanisms
// from being bypassed. Otherwise, the salt value `salt` is not modified.
guardedSalt = (salt != _generateSalt())
? keccak256(abi.encode(salt))
: salt;
}
}
```
Please note that when you configure a permissioned deploy protection, you **must** specify whether you want cross-chain redeploy protection (i.e. 21st byte equals `0x01`) or not (i.e. the 21st byte equals `0x00`). The underlying reason for this logic is to enforce developer explicitness. If you don't specify a cross-chain redeploy protection decision (i.e. the 21st byte is greater than `0x01`) the function reverts.
Furthermore, you can configure _only_ cross-chain redeploy protection by setting the first 20 bytes equal to the zero address `0x0000000000000000000000000000000000000000`. The rationale behind this logic is to prevent a pseudo-randomly generated 32 byte salt from inadvertently activating cross-chain redeploy protection. Also in this case, if you don't specify a cross-chain redeploy protection, i.e. the 21st byte is greater than `0x01`, the function reverts. The underlying reason for this logic is as well to enforce developer explicitness.
> [!IMPORTANT]
> When using the read-only functions [`computeCreate2Address(bytes32,bytes32)`](https://github.com/pcaversaccio/createx/blob/main/src/CreateX.sol#L600-L610) or [`computeCreate3Address(bytes32)`](https://github.com/pcaversaccio/createx/blob/main/src/CreateX.sol#L857-L867), it is essential to provide the _guarded_ `salt` value, meaning the value after being processed by the `_guard` function, as the input parameter. This ensures the correct computation of the deployment address. For more details, refer to [this issue](https://github.com/pcaversaccio/createx/issues/140).
### Pseudo-Random Salt Value
For developer convenience, the [`CreateX`](./src/CreateX.sol) contract offers several overloaded functions that generate the salt value pseudo-randomly using a diverse selection of block and transaction properties. Please note that this approach does not guarantee true randomness!
The full logic is implemented in the `internal` [`_generateSalt`](./src/CreateX.sol#L960-L988) function:
```solidity
function _generateSalt() internal view returns (bytes32 salt) {
unchecked {
salt = keccak256(
abi.encode(
// We don't use `block.number - 256` (the maximum value on the EVM) to accommodate
// any chains that may try to reduce the amount of available historical block hashes.
// We also don't subtract 1 to mitigate any risks arising from consecutive block
// producers on a PoS chain. Therefore, we use `block.number - 32` as a reasonable
// compromise, one we expect should work on most chains, which is 1 epoch on Ethereum
// mainnet. Please note that if you use this function between the genesis block and block
// number 31, the block property `blockhash` will return zero, but the returned salt value
// `salt` will still have a non-zero value due to the hashing characteristic and the other
// remaining properties.
blockhash(block.number - 32),
block.coinbase,
block.number,
block.timestamp,
block.prevrandao,
block.chainid,
msg.sender
)
);
}
}
```
## Design Principles
- [`CreateX`](./src/CreateX.sol) should cover _most_ but not all contract creation use cases.
- [`CreateX`](./src/CreateX.sol) should be human-readable and should be simple to understand for readers with low prior experience.
- [`CreateX`](./src/CreateX.sol) should be maximally secure, i.e. no hidden footguns.
- [`CreateX`](./src/CreateX.sol) should be trustless.
- [`CreateX`](./src/CreateX.sol) should be stateless.
- [`CreateX`](./src/CreateX.sol) should be extensible (i.e. it can be used to deploy protocols, within protocols, or to deploy other types of deterministic deployer factories).
The following consequences result from these principles:
- We only use inline assembly if it is required or if the code section itself is based on short and/or audited code.
- We document the contract to the smallest detail.
- We extensively fuzz test all functions.
- We deliberately do not implement special functions for [clones with immutable arguments](https://github.com/wighawag/clones-with-immutable-args), as there is neither a finalised standard nor a properly audited contract version.
- We do not implement any special functions for [EIP-5202](https://eips.ethereum.org/EIPS/eip-5202) (a.k.a. blueprint contracts), as all existing functions in [`CreateX`](./src/CreateX.sol) are already cost-effective alternatives in our opinion.
## Security Considerations
> [!WARNING]
> **This contract is unaudited!** Special thanks go to [Oleksii Matiiasevych](https://github.com/lastperson) for his thorough review and feedback 🙏🏽.
Generally, for security issues, see our [Security Policy](./SECURITY.md). Furthermore, you must be aware of the following aspects:
- Several functions allow for reentrancy, however we refrain from adding a mutex lock to keep it as use-case agnostic as possible. Please ensure at the protocol level that potentially malicious reentrant calls do not affect your smart contract system.
- In the functions:
- [`deployCreate3(bytes32,bytes)`](https://github.com/pcaversaccio/createx/blob/main/src/CreateX.sol#L616-L646),
- [`deployCreate3AndInit(bytes32,bytes,bytes,tuple(uint256,uint256))`](https://github.com/pcaversaccio/createx/blob/main/src/CreateX.sol#L725-L760), and
- [`deployCreate3AndInit(bytes32,bytes,bytes,tuple(uint256,uint256),address)`](https://github.com/pcaversaccio/createx/blob/main/src/CreateX.sol#L665-L723)
we strongly recommend implementing a permissioned deploy protection by setting the first 20 bytes equal to `msg.sender` in the `salt` to prevent maliciously intended frontrun proxy deployments on other chains.
- The target EVM version for compilation is set to [`paris`](https://github.com/ethereum/execution-specs/blob/master/network-upgrades/mainnet-upgrades/paris.md), i.e. neither the contract creation bytecode of [`CreateX`](./src/CreateX.sol) nor the returned runtime bytecode contains a [`PUSH0`](https://www.evm.codes/#5f?fork=shanghai) instruction.
- Please refer to our comment in the discussion [here](https://github.com/pcaversaccio/createx/discussions/61#discussioncomment-7937359) for background information on the risks of our private-key-based deployment approach. We recommend verifying prior to interacting with [`CreateX`](./src/CreateX.sol) on any chain, that the `keccak256` hash of the broadcasted contract creation bytecode is `0x12ec861579b63a3ab9db3b5a23c57d56402ad3061475b088f17054e2f2daf22f` or of the deployed runtime bytecode is `0xbd8a7ea8cfca7b4e5f5041d7d4b17bc317c5ce42cfbc42066a00cf26b43eb53f`.
## Tests
For all (fuzz) tests available in the [`test`](./test) directory, we have consistently applied the [Branching Tree Technique](https://x.com/PaulRBerg/status/1682346315806539776) with [`bulloak`](https://github.com/alexfertel/bulloak). This means that each test file is accompanied by a `.tree` file that defines all the necessary branches to be tested.
**Example ([`CreateX._guard.tree`](./test/internal/CreateX._guard.tree)):**
```tree
CreateX_Guard_Internal_Test
├── When the first 20 bytes of the salt equals the caller
│ ├── When the 21st byte of the salt equals 0x01
│ │ └── It should return the keccak256 hash of the ABI-encoded values msg.sender, block.chainid, and the salt.
│ ├── When the 21st byte of the salt equals 0x00
│ │ └── It should return the keccak256 hash of the ABI-encoded values msg.sender and the salt.
│ └── When the 21st byte of the salt is greater than 0x01
│ └── It should revert.
├── When the first 20 bytes of the salt equals the zero address
│ ├── When the 21st byte of the salt equals 0x01
│ │ └── It should return the keccak256 hash of the ABI-encoded values block.chainid and the salt.
│ ├── When the 21st byte of the salt equals 0x00
│ │ └── It should return the keccak256 hash of the ABI-encoded value salt.
│ └── When the 21st byte of the salt is greater than 0x01
│ └── It should revert.
└── When the first 20 bytes of the salt do not equal the caller or the zero address
├── It should return the keccak256 hash of the ABI-encoded value salt.
└── When the salt value is generated pseudo-randomly
└── It should return the unmodified salt value.
```
### Test Coverage
This project repository uses [`forge coverage`](https://book.getfoundry.sh/reference/forge/forge-coverage). Simply run:
```console
forge coverage
```
In order to generate an `HTML` file with the coverage data, you can invoke:
```console
pnpm coverage:report
```
The written tests available in the directory [`test`](./test) achieve a test coverage of **100%** for the [`CreateX`](./src/CreateX.sol) contract:
```console
| File | % Lines | % Statements | % Branches | % Funcs |
|-----------------|-------------------|-------------------|-----------------|-----------------|
| src/CreateX.sol | 100.00% (149/149) | 100.00% (210/210) | 100.00% (78/78) | 100.00% (31/31) |
```
> [!IMPORTANT]
> A test coverage of 100% does not mean that there are no vulnerabilities. What really counts is the quality and spectrum of the tests themselves!
## ABI (Application Binary Interface)
> [!TIP]
> If you `forge install` this repository, the Solidity-based interface can also be found [here](./src/ICreateX.sol).

## New Deployment(s)
We offer two options for deploying [`CreateX`](./src/CreateX.sol) to your desired chain:
1. Deploy it yourself by using one of the pre-signed transactions. Details can be found in the subsequent paragraph.
2. Request a deployment by opening an [issue](https://github.com/pcaversaccio/createx/issues/new?assignees=pcaversaccio&labels=new+deployment+%E2%9E%95&projects=&template=deployment_request.yml&title=%5BNew-Deployment-Request%5D%3A+). You can significantly reduce the time to deployment by sending funds to cover the deployment cost (a reliable amount with a small tip 😏 would be ~0.3 ETH) to the deployer account: `0xeD456e05CaAb11d66C4c797dD6c1D6f9A7F352b5`.
> [!CAUTION]
> Prior to using a pre-signed transaction, you **MUST** ensure that the gas metering of the target chain is **EQUIVALENT** to that of Ethereum's EVM version!
>
> The _default_ pre-signed transaction has a gas limit of 3,000,000 gas, so if the target chain requires more than 3 million gas to deploy, the contract creation transaction will revert and we will not be able to deploy [`CreateX`](./src/CreateX.sol) to the address `0xba5Ed099633D3B313e4D5F7bdc1305d3c28ba5Ed`. In this case, the only way to get [`CreateX`](./src/CreateX.sol) deployed at the expected address is for the chain to store the contract there as a predeploy.
>
> If you are not sure how to validate this, you can either use the [`eth_estimateGas`](https://ethereum.github.io/execution-apis/api-documentation/) JSON-RPC method or simply deploy the [`CreateX`](./src/CreateX.sol) contract from another account and see how much gas is needed for the deployment. Standard EVM chains should require exactly 2,580,902 gas to deploy [`CreateX`](./src/CreateX.sol).
We repeat: PLEASE DO NOT BROADCAST ANY PRE-SIGNED TRANSACTION WITHOUT LOCAL TESTING! Also, before deploying, you MUST send at least 0.3 ETH to the deployer address `0xeD456e05CaAb11d66C4c797dD6c1D6f9A7F352b5`. We offer three pre-signed, pre-[`EIP-155`](https://eips.ethereum.org/EIPS/eip-155) transactions with the same gas price of 100 gwei, but different `gasLimit` levels:
- _Default Case:_ `gasLimit = 3_000_000`; [`signed_serialised_transaction_gaslimit_3000000_.json`](./scripts/presigned-createx-deployment-transactions/signed_serialised_transaction_gaslimit_3000000_.json),
- _Medium Case:_ `gasLimit = 25_000_000`; [`signed_serialised_transaction_gaslimit_25000000_.json`](./scripts/presigned-createx-deployment-transactions/signed_serialised_transaction_gaslimit_25000000_.json),
- _Heavy Case:_ `gasLimit = 45_000_000`; [`signed_serialised_transaction_gaslimit_45000000_.json`](./scripts/presigned-createx-deployment-transactions/signed_serialised_transaction_gaslimit_45000000_.json).
You can broadcast the transaction using either [`ethers.js`](https://docs.ethers.org/v6/) or [`cast`](https://book.getfoundry.sh/reference/cli/cast):
#### [`ethers.js`](https://docs.ethers.org/v6/)
It is recommended to install [`pnpm`](https://pnpm.io) through the `npm` package manager, which comes bundled with [Node.js](https://nodejs.org/en) when you install it on your system. It is recommended to use a Node.js version `>= 22.0.0`.
Once you have `npm` installed, you can run the following both to install and upgrade `pnpm`:
```console
npm install -g pnpm
```
After having installed `pnpm`, simply run:
```console
git clone https://github.com/pcaversaccio/createx.git
cd createx
pnpm install
```
Now configure your target chain in the [`hardhat.config.ts`](./hardhat.config.ts) file with the `networks` and `etherscan` properties, or use one of the preconfigured network configurations. After you have locally ensured that the `gasLimit` of 3 million works on your target chain, you can invoke:
```console
npx hardhat run --no-compile --network scripts/deploy.ts
```
The [`deploy.ts`](./scripts/deploy.ts) script ensures that [`CreateX`](./src/CreateX.sol) is automatically verified if you have configured the `etherscan` property accordingly. The current script broadcasts the _default_ pre-signed transaction, which has a gas limit of 3,000,000 gas. If you want to use a different pre-signed transaction, you must change the import of the pre-signed transaction in the [`deploy.ts`](./scripts/deploy.ts) script.
#### [`cast`](https://book.getfoundry.sh/reference/cli/cast)
It is recommended to install [Foundry](https://github.com/foundry-rs/foundry) via:
```console
curl -L https://foundry.paradigm.xyz | bash
foundryup
```
To broadcast a pre-signed transaction, you can invoke:
```console
# $TX is the pre-signed transaction.
# $RPC_URL is the RPC URL of the target chain to which you want to deploy.
cast publish $TX --rpc-url $RPC_URL
```
You must verify the [`CreateX`](./src/CreateX.sol) contract separately, as specified in the next section.
> [!IMPORTANT]
> After deployment, please open a pull request that updates the [`deployments.json`](./deployments/deployments.json) file and the [`CreateX` Deployments](#createx-deployments) section with the new deployment so that other users can easily know that it has been deployed.
### Contract Verification
To verify a deployed [`CreateX`](./src/CreateX.sol) contract on a block explorer, use the following parameters:
- _Verification Method / Compiler Type:_ `Solidity (Standard JSON Input)`,

> [!IMPORTANT]
> We removed the metadata hash `bytecodeHash` from the bytecode in order to guarantee a deterministic compilation across all operating systems. This implies that all [sourcify.eth](https://sourcify.dev) verifications have partial verification, as opposed to [perfect verification](https://docs.sourcify.dev/blog/verify-contracts-perfectly/), which requires a matching metadata hash.
