Deploy a smart contract
$ forge create --help
Usage: forge create [OPTIONS] <CONTRACT>
Arguments:
<CONTRACT>
The contract identifier in the form `<path>:<contractname>`
Options:
--constructor-args <ARGS>...
The constructor arguments
--constructor-args-path <PATH>
The path to a file containing the constructor arguments
--broadcast
Broadcast the transaction
--verify
Verify contract after creation
--unlocked
Send via `eth_sendTransaction` using the `--from` argument or
`$ETH_FROM` as sender
--show-standard-json-input
Prints the standard json compiler input if `--verify` is provided.
The standard json compiler input can be used to manually submit
contract verification in the browser.
--timeout <TIMEOUT>
Timeout to use for broadcasting transactions
[env: ETH_TIMEOUT=]
-h, --help
Print help (see a summary with '-h')
-j, --threads <THREADS>
Number of threads to use. Specifying 0 defaults to the number of
logical cores
[aliases: jobs]
Cache options:
--force
Clear the cache and artifacts folder and recompile
Build options:
--no-cache
Disable the cache
--eof
Use EOF-enabled solc binary. Enables via-ir and sets EVM version to
Prague. Requires Docker to be installed.
Note that this is a temporary solution until the EOF support is merged
into the main solc release.
--skip <SKIP>...
Skip building files whose names contain the given filter.
`test` and `script` are aliases for `.t.sol` and `.s.sol`.
Linker options:
--libraries <LIBRARIES>
Set pre-linked libraries
[env: DAPP_LIBRARIES=]
Compiler options:
--ignored-error-codes <ERROR_CODES>
Ignore solc warnings by error code
--deny-warnings
Warnings will trigger a compiler error
--no-auto-detect
Do not auto-detect the `solc` version
--use <SOLC_VERSION>
Specify the solc version, or a path to a local solc, to build with.
Valid values are in the format `x.y.z`, `solc:x.y.z` or
`path/to/solc`.
--offline
Do not access the network.
Missing solc versions will not be installed.
--via-ir
Use the Yul intermediate representation compilation pipeline
--no-metadata
Do not append any metadata to the bytecode.
This is equivalent to setting `bytecode_hash` to `none` and
`cbor_metadata` to `false`.
--ast
Includes the AST as JSON in the compiler output
--evm-version <VERSION>
The target EVM version
--optimize [<OPTIMIZE>]
Activate the Solidity optimizer
[possible values: true, false]
--optimizer-runs <RUNS>
The number of runs specifies roughly how often each opcode of the
deployed code will be executed across the life-time of the contract.
This means it is a trade-off parameter between code size (deploy cost)
and code execution cost (cost after deployment). An `optimizer_runs`
parameter of `1` will produce short but expensive code. In contrast, a
larger `optimizer_runs` parameter will produce longer but more gas
efficient code
--extra-output <SELECTOR>...
Extra output to include in the contract's artifact.
Example keys: evm.assembly, ewasm, ir, irOptimized, metadata
For a full description, see
<https://docs.soliditylang.org/en/v0.8.13/using-the-compiler.html#input-description>
--extra-output-files <SELECTOR>...
Extra output to write to separate files.
Valid values: metadata, ir, irOptimized, ewasm, evm.assembly
Project options:
-o, --out <PATH>
The path to the contract artifacts folder
--revert-strings <REVERT>
Revert string configuration.
Possible values are "default", "strip" (remove), "debug"
(Solidity-generated revert strings) and "verboseDebug"
--build-info
Generate build info files
--build-info-path <PATH>
Output path to directory that build info files will be written to
--root <PATH>
The project's root path.
By default root of the Git repository, if in one, or the current
working directory.
-C, --contracts <PATH>
The contracts source directory
-R, --remappings <REMAPPINGS>
The project's remappings
--remappings-env <ENV>
The project's remappings from the environment
--cache-path <PATH>
The path to the compiler cache
--lib-paths <PATH>
The path to the library folder
--hardhat
Use the Hardhat-style project layout.
This is the same as using: `--contracts contracts --lib-paths
node_modules`.

--config-path <FILE>
Path to the config file

for failing tests.
