contract SafePool {
constructor(string memory _name, address Owner ,address TokenAddress) {
        name = _name;
        owner = Owner;
        token_address = TokenAddress;
//other codes

contract SafePoolFactory {
 constructor(address Token_Address)  {

You can verify using tool like Foundry or Hardhat, after compiling the contract that’s being created by your factory contract.

Using Foundry:

  1. Compile the contract:

    forge compile
  2. Then, you can use the forge verify-contract command like this:

    forge verify-contract \
        --chain-id 11155111 \
        --num-of-optimizations 1000000 \
        --watch \
        --constructor-args $(cast abi encode "constructor(string,string,uint256,uint256)" "ForgeUSD" "FUSD" 18 1000000000000000000000) \
        --etherscan-api-key <your_etherscan_api_key> \
        --compiler-version v0.8.10+commit.fc410830 \
        <the_contract_address> \

Using Hardhat:

  1. Compile the contract:

    npx hardhat compile
  2. Then, you can use the hardhat-verify plugin, and verify the contract using command like this:

    npx hardhat verify --network NETWORK_NAME DEPLOYED_CONTRACT_ADDRESS "Constructor argument 1" "Constructor argument 2"
