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.

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 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 $$$.

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 eips.ethereum.org/EIPS/eip-7…

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.
