forge verify-contract
NAME
forge-verify-contract - Verify smart contracts on Etherscan.
SYNOPSIS
forge verify-contract [options] --compiler-version compiler_version address contract [etherscan_key]
DESCRIPTION
Verifies a smart contract on Etherscan.
You must provide:
- The compiler version used to build your smart contracts (
--compiler-version, read below) - The contract address
- The path to the contract (read below)
- Your Etherscan API key, either by passing it as an argument or setting
ETHERSCAN_API_KEY
To find the exact compiler version, run ~/.svm/x.y.z/solc-x.y.z --version and search for the 8 hex digits in the version string here.
The path to the contract is in the format <path>:<contract>, e.g. src/Contract.sol:Contract.
By default, smart contracts are verified in a multi-file fashion. If you want to flatten the contract before verifying, pass --flatten.
This command will try to compile the source code of the flattened contract if --flatten is passed before verifying. If you do not want that, pass --force.
OPTIONS
Verify Contract Options
--compiler-version version
The compiler version used to build the smart contract.
To find the exact compiler version, run ~/.svm/x.y.z/solc-x.y.z --version where x and
y are major and minor version numbers respectively, then search for the 8 hex digits in the version string here.
--num-of-optimizations num
The number of optimization runs used to build the smart contract.
--constructor-args args...
The ABI-encoded constructor arguments.
--chain-id chain_id
The chain ID the contract is deployed to (either a number or a chain name).
Default: mainnet
--flatten
Flatten the source code before verifying.
-f
--force
Do not compile the flattened smart contract before verifying.
--delay delay
Optional timeout to apply in between attempts in seconds.
--retries retries
Number of attempts for retrying. Defaults to 1.
--watch
Wait for verification result after submission.
Automatically runs forge verify-check until the verification either fails or succeeds.
Project Options
--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, this is the root directory of the current git repository, or the current working directory.
-c path
--contracts path
The contracts source directory.
Environment: DAPP_SRC
--lib-paths path
The path to the library folder.
-r remappings
--remappings remappings
The project's remappings.
The parameter is a comma-separated list of remappings in the format <source>=<dest>.
--cache-path path
The path to the compiler cache.
--config-path file
Path to the config file.
--hh
--hardhat
This is a convenience flag, and is the same as passing --contracts contracts --lib-paths node-modules.
Common Options
-h
--help
Prints help information.
EXAMPLES
- Verify a contract built with solc v0.8.11+commit.d7f03943:
forge verify-contract --compiler-version "v0.8.11+commit.d7f03943" \ 0x.. src/Token.sol:MyToken
