New Solidity Smart Contract Verification
Contract Address
The 0x address supplied on contract creation.
Contract Name
Must match the name specified in the code. For example, in
contract MyContract {..}
MyContract
is the contract name.
Include nightly builds
No
Yes
Select yes if you want to show nightly builds.
Compiler
The compiler version is specified in
pragma solidity X.X.X
. Use the compiler version rather than the nightly build. If using the Solidity compiler, run
solc —version
to check.
EVM Version
homestead
tangerineWhistle
spuriousDragon
byzantium
constantinople
petersburg
istanbul
berlin
london
default
The EVM version the contract is written for. If the bytecode does not match the version, we try to verify using the latest EVM version.

Optimization
No
Yes
If you enabled optimization during compilation, select yes.

// SPDX-License-Identifier: MIT pragma solidity ^0.8.0; import "../Proxy.sol"; import "./ERC1967Upgrade.sol"; /** * @dev This contract implements an upgradeable proxy.

We recommend using flattened code. This is necessary if your code utilizes a library or inherits dependencies. Use the
POA solidity flattener or the
truffle flattener
.
Try to fetch constructor arguments automatically
No

Add arguments in
ABI hex encoded form
. Constructor arguments are written right to left, and will be found at the end of the input created bytecode. They may also be
parsed here.
Add Contract Libraries
Contract Libraries
Library Name
A library name called in the .sol file. Multiple libraries (up to 5) may be added for each contract. Click the Add Library button to add an additional one.
Library Address
The 0x library address. This can be found in the generated json file or Truffle output (if using truffle).
