A program to calculate the address deployed from a contract using create2. It can also be used to find a salt which generates an address with a particular sequence of start or end hex values. This is written in Rust to encourage myself to become more familiar with the language and to learn its unique features.

The program can be used as follows:

1. Calculate the deployed address given a deployed address, salt and initcode:

   ./create2calc calc <address> <salt> <code>
   

   Example:

   ./create2calc calc --address 0x1234 --code 0x1234567890 --salt 0x4321
   Deployed address: 1892225c1b09454c18418c380603021c26e8b6ff
   

2. Find some salt to deploy an address with the specific sequence of hex values:

   ./create2calc find <address> <salt> --start <sequence> --end <sequence>
   

   Example:

   ./create2calc find --address 0x1234 --code 0x1234567890 --start 0x222 --end 0x333
   Found: 2222cbd6bc152fab9b5312a333de108e63c333
   For deployer: 0000000000000000000000000000000000001234
   With init code: 1234567890
   Using salt: f9327c7c264fb331cf8ad0f22c2759770ebe835b469e4f3382e654b02c4b024b
   
   ./create2calc find --address 0x1 --code 0x111 --start 0x1234
   Found: 123407b6d1c03cd97331e8b4e01e529b278e6b
   For deployer: 0000000000000000000000000000000000000001
   With init code: 0111
   Using salt: 06e03da6a716735d984ee55f0d799457c9ea1cc01049e285fd01cb7427d4ddc0
   

The arguments work with or without the hex 0x prepend.

The following is a list of previously completed or future improvements:

• Enum arguments
• Generic arguments
• Add support for non-standard arguments
  • Varying lengths for address and salt
  • Hex input 0x prepend optional
• Add CLI interface rather than hardcoding values
• Move important logic into separate library
• Add support for bruteforcing desired beginning or end hex sequences
  • Multithreading
