Create 2 Patterns
summary
Create2 is presented as the primitive that enables counterfactual wallets and address-encoded metadata by using a factory, salt and init code so addresses are deterministic; actual builds include lazy wallets (send assets before deploy), Uniswap-style deterministic pools, an L2 token-address oracle, a withdraw-via-deploy UX hack, and a proof-of-concept c2c NFT bridge repo that works but pushes complexity to withdrawals. Notes: resurrecting via self-destruct is possible but fragile, duplicate salts fail, and deposits boil down to the minimal transfer+mint pattern.
