ProxyFactory Test
Testing the ProxyFactory contract for cheaper deployment of copies of contracts.
Status: Testing completed. Get your code audited before using the code from this repo in production.
WARNING: Use with utmost care!
Information from:
- https://www.reddit.com/r/ethereum/comments/6c1jui/delegatecall_forwarders_how_to_save_5098_on/
- Creating the forwarding contract only costs <50000 gas, regardless of the length of the underlying call
- Constructor functions are currently not supported, though the mechanism could be expanded with more effort to support constructors.
- The output length is limited to 4096 bytes
- Each call to the contract thereafter will cost an additional ~1100 gas (700 DELEGATECALL + 400 memory expansion)
