This is a proxy contract that can be deployed to any chain at the same address, and can then in turn deploy any contract at a deterministic location using CREATE2. To use, first deploy the contract using the one-time-account transaction specified in output/deployment.json (or grab last known good from bottom of readme), then submit a transaction to the address specified in output/deployment.json (or grab last known good from bottom of readme) and supply your init code as the data. This is just like deploying a transaction normally, except change the to field from null.
npm install
npm run build
./scripts/test.shSee scripts/test.sh (commented). Change JSON_RPC environment variable to the chain of your choice (requires an unlocked wallet with ETH). Notice that the script works against any chain! If the chain already has the deployer contract deployed to it, then you can just comment out the deployment steps (line 20 and 23) and everything else will still function as normal. If you have already deployed your contract with it to the chain you are pointing at, the script will fail because your contract already exists at its address.
This repository contains a simple contract that can deploy other contracts with a deterministic address on any chain using CREATE2. The CREATE2 call will deploy a contract (like CREATE opcode) but instead of the address being keccak256(rlp([deployer_address, nonce])) it instead uses the hash of the contract's bytecode and a salt. This means that a given deployer address will deploy the same code to the same address no matter when or where they issue the deployment. The deployer is deployed with a one-time-use-account, so no matter what chain the deployer is on, its address will always be the same. This means the only variables in determining the address of your contract are its bytecode hash and the provided salt.
Between the use of CREATE2 opcode and the one-time-use-account for the deployer, we can ensure that a given contract will exist at the exact same address on every chain, but without having to use the same gas # or limits every time.
Note: as of last readme update; don't trust these to be latest!

Note: The actual gas used is 62095, but that can change if the cost of opcodes changes. To avoid having to move the proxy to a different address, we opted to give excess gas. Given the gas price, this may result in notable expenses, but since this only needs to be deployed once per chain that is acceptable.
