Next steps on Seaport migration

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.

Open-sourcing Seaport data abstraction

Over the next few days, OpenSea will be migrating to Seaport, a brand new web3 marketplace protocol designed for safely and efficiently buying and selling NFTs. We’re going to be one of the first marketplaces using the core Seaport smart contract to build new features for the OpenSea community.

Migrating to the Seaport protocol

Last week, we unpacked the early details of OpenSea’s new open-source protocol – Seaport – for the developer community. Seaport will become the foundation for OpenSea’s core products, unlocking a range of new use cases for creators, collectors, and the broader developer ecosystem. The protocol is non-custodial, non-upgradeable, and decentralized at its core — it belongs to the community first & foremost. And in that spirit, we’re inviting the community to join us in early testing via a $1M Code4rena contest.
