TL;DR: Unfortunately, it is not possible to deploy the Create2Deployer contract on the Base production network.

Background

When bridging the funds to the Base mainnet, Base applied a recently introduced (but unfortunately unexpected) behaviour in the Bedrock upgrade that essentially sends a self transfer on L2. I.e. the nonce of the deployer account 0x554282cf65b42fc8fddc6041eb24ce5e8a0632ad was increased by 1 before deploying the Create2Deployer contract. Unfortunately, this means that I can no longer deploy the contract to 0x13b0D85CcB8bf860b6b79AF3029fCA081AE9beF2. If the demand for this chain is high enough, I might consider redeploying the Create2Deployer contract to a new address including the Base mainnet.

Ouffffff this is so sad :((( What would be the alternatives to how to deploy on Base?

Well I got good news for you: ethereum-optimism/op-geth#126. It will be added as predeploy to Base. This might take however until January most probably.

By the way, question. If you will include an option to selfdestruct in the new version of Create2Deployer, this would allow in case of such problems to destroy the contract and re-deploy it, right?

Would it pose any security risks? I guess it would not, right?

Then maybe you could add it in the new version so that if similar problems happen in the future, they are not so huge.

There will be no selfdestruct nor any other governance function in the new Create2Deployer! If you wanna have a look at the new version, here you go: https://github.com/pcaversaccio/createx. It's muuuuuch more powerful now and will also be available on Base Mainnet.

As of xdeployer v3.0.0, baseMain deployments are possible 🍻!
