Today we are introducing support for the Polygon Amoy testnet, which replaces Mumba as the new Sepolia-backed testnet. Mumbai will be deprecated on Friday due to node providers spinning down their services.

If you need test MATIC tokens on Amoy, Alchemy provides a great faucet: https://t.co/zOt7umjt3s

Big thanks to my fellow coauthors and contributors in the Seaport Working Group for making this release a reality

Excited to see what you all build using Seaport Hooks!

[OpenSea @opensea]

OpenSea and the Seaport Working Group are thrilled to unveil Seaport 1.6 — the latest generation of the most advanced NFT marketplace protocol in the EVM ecosystem.

Seaport 1.6 introduces a new capability enabled by the recent Ethereum Dencun upgrade called Seaport hooks 🪝. Similar in spirit to Uniswap v4 hooks, Seaport hooks allow developers to build applications that greatly expand the utility and liquidity of NFTs.

Seaport hooks allow developers to create:
-NFTs whose traits modify or “upgrade” in response to the price or volume in which they’re purchased
-NFTs that can only be bought with certain currencies or other NFTs
-Bonding curves for automatically priced NFTs
-Price oracles for NFTs
-Many, many more applications to be dreamt up yet

PS: Seaport 1.6 is up to 5% cheaper in gas than Seaport 1.5 for certain actions, saving you $$$.

2/ It's critical that our developer ecosystem has access to an easy to use, accurate, and detailed hub for documentation. Please let us know how we can further improve the docs!

[OpenSea Developers @openseadevs]

1/ Check out the newest version of our the OpenSea Developer Hub at https://t.co/SXtBctAbay - we created a new home page, added some "How To" guides for beginners, and revamped our API, Protocol, Primary Drops technical documentation.

2/ Just using ERC-173's owner() is not a bulletproof method as anyone can assign any non-consenting owner. We hope supporting this standard creates a better way to prove contract creation/ownership.

[OpenSea Developers @openseadevs]

1/ OpenSea now supports ERC-7015: NFT Creator Attribution for a more concrete method for proving opt-in contract ownership. The creator emits a log containing a signature confirming the contract deployment https://t.co/YuP95kEZqb

We've changed our handle on @X from @apiopensea to @openseadevs - this is the official account for all @opensea developer communications.

"ERC-7572: Contract-level metadata via contractURI()" has been merged into the canonical ERCs repo. This has been a long-supported standard by OpenSea, and now includes a newly introduced event `ContractURIUpdated()` for notifying updates https://t.co/scC0m5vkUW
