The Seaport version 1.2 contract is now deployed to many EVM chains! 0x00000000000006c7676171937C444f6BDe3D6282 The current Seaport contract (v1.1) is still usable & will be as long as whatever chain it's on keeps chugging; v1.2 is a new contract So, what's v1.2 all about? ⤵️

honored to contribute to punks lore by bringing metadata for the new wrapper fully onchain 🙏 the punks metadata was put onchain in 2021, but it wasn’t actually associated with the og punks or wrapper contract… until now 😎 shout out to my fellow onchain maxis 🫡

6/ Ͼ721 is immutable, permissionless, efficient, and leverages the @larvalabs PunksData contract from 2021 for fully onchain metadata. Huge shout out to @optimizoor for a wildly optimized 721 base, and @emo_eth for a metadata contract to parse PunksData into a valid tokenURI.

@worm_emoji @AlexMasmej yeah, seems to save 253 bytes with the same compiler settings specifying more optimizer runs results in more gas-efficient code but larger code size, so anywhere you can shave off bytes from the contract code can lead to gas savings (19066 optimizer runs in the deployed version)

Random Foundry tip. Don't remap your dependencies with a trailing "src/". Rather, use "src" in the actual import paths written in your contracts. This is to ensure compatibility with Hardhat projects.
