Deploying the first Implementation Contract

Deploy to the ropsten testnet

npx hardhat run scripts/deploy.js --network ropsten

ERC20PresetMinterPauserUpgradeSafe deployed. Proxy Contract Address is 0x7fBD91A756a4Be97f0b7C7BD4F8bE1A36406D1c3

Verify contract source code

In order to verify the contract source code, we would need to know the address of the Implementation Contract, and not the address of the Proxy Contract that was provided in Step 1 above.

The Implementation Contract address can be obtained from the artifacts within the .openzeppelin folder, and also from Etherscan directly. Follow the Verify instructions here to obtain the address of the implementation via Etherscan.

npx hardhat verify YOUR_IMPLEMENTATION_CONTRACT_ADDRESS --network ropsten

Transfer ownership to ProxyAdmin

Once deployed, the deployer must transfer the ownership of the contract to a MultiSig wallet (the ProxyAdmin address)

npx hardhat run scripts/transfer_ownership.js --network ropsten

Check Roles Allocation

On being initialized the first time, the contract will automatically grant the ADMIN_ROLE and MINTER_ROLE to the address provided as the third argument to the initialize function. The PAUSER_ROLE is also granted on initialization to the pauserSafeAccount, which is the fourth argument to the initialize function.

Please see the deploy.js script for how these arguments are passed to the contract during initialization.
