Deterministic Deployment

1. Run foundryup and install the foundry toolchain.
2. Replace the 0x04 with the minter's Ethereum address in script/CkIcp.s.sol in line new CkIcp{salt: bytes32(uint256(1))}(address(0x04));.
3. Register an Etherscan account and export ETHERSCAN_API_KEY.
4. For mainnet deployment: change eth_rpc_url and chain_id in foundry.toml.
5. Run forge script script/CkIcp.s.sol -v --private-key $DEPLOYER_SK --broadcast --etherscan-api-key $ETHERSCAN_API_KEY --verify.
6. The Airdrop.sol does not need a deterministic address and can be deployed using forge create --private-key $DEPLOYER_SK src/Airdrop.sol:Airdrop --etherscan-api-key $ETHERSCAN_API_KEY --verify.
7. Commit broadcast/CkIcp.s.sol/{chain_id}/*.json back to this repo.
