Upgrading Contracts

Sometimes, we need to fix problems in our smart contracts. We can do this by upgrading contracts that use ERC1967Proxy. Here's how to do it:

Upgrading the Verifier

  1. Change the code in this file: packages/contracts/src/utils/Verifier.sol

  2. Add this to your .env file:

    VERIFIER={DEPLOYED_VERIFIER_PROXY_ADDRESS}

  3. Run this command:

    source .env
forge script script/Upgrades.s.sol:Upgrades --rpc-url $RPC_URL --chain-id $CHAIN_ID --etherscan-api-key $ETHERSCAN_API_KEY --broadcast --verify -vvvv

Upgrading Other Contracts

You can also upgrade ECDSAOwnedDKIMRegistry and UserOverrideableDKIMRegistry:

For ECDSAOwnedDKIMRegistry:

  1. Change the code in: packages/contracts/src/utils/ECDSAOwnedDKIMRegistry.sol

  2. Add to .env:

    ECDSA_DKIM={DEPLOYED_ECDSA_DKIM_PROXY_ADDRESS}

For UserOverrideableDKIMRegistry:

  1. Change the code in: @zk-email/contracts/UserOverrideableDKIMRegistry.sol

  2. Add to .env:

    DKIM={DEPLOYED_USEROVERRIDEABLE_DKIM_PROXY_ADDRESS}

Remember to be careful when changing these contracts. Always test your changes before using them.
