Announcing a contract upgrade

Update: as of 2/25/22 our contract upgrade is completed.

TL;DR – We’re upgrading the smart contract we use to help address the inactive listings issue on Ethereum. The upgrade ensures that old, inactive listings expire, enables bulk cancellation with a single, low cost transaction, and allows us to roll out new features like bulk cancellation and more descriptive signatures. There are a few actions required of anyone with active listings:

As of today, Friday, February 18 at 3pm ET, you can start migrating your listings to the new Wyvern smart contract. You will have 1 week to move all your existing listings to the new contract. At 2pm ET on Friday, February 25, any listings you have not migrated will expire. If you miss the window to migrate your listings to the new contract, you will be able to re-list your expired listings without incurring any additional fees (including gas fees). Any new listings made during this 7-day migration period will automatically be set to the new contract (so no additional effort is required for new listings).
