Earlier today, we announced that we’ve started to migrate to Seaport, a new web3 marketplace protocol designed for safely and efficiently buying and selling NFTs.  Following up on our detailed migration guide for developers that we had shared a few weeks ago, we’re highlighting the implications for developers at this milestone.

To recap, here’s what developers can expect from today (June 14) forward:

June 14

API: Begin using the new Seaport offers and listings endpoints on Mainnet

API: Begin parsing new Seaport offers and listings from /assets and /bundles endpoints on Testnets

SDK: Begin using new Seaport-ready functions in SDK v4.0.0 on Mainnet

June 21

API+ SDK: Offers and listings can no longer be posted to Wyvern v2.3 contract using OpenSea

July 13

API + SDK: Offers and listings can no longer be fetched from Wyvern v2.3 contract using OpenSea

For more details on each of these updates, please refer back to our detailed Seaport migration guide.  If you have any questions, please reach out on Discord as we’re here to help.
