Gutter Market
US
Gutter Market is a peer-to-peer NFT marketplace and launchpad for Gutter Cat Gang collections based on Seaport Protocol.
Aegas team had collaborated with project founders Gutter Labs on Gutter Cat Gang since August 2021 until project acquisition by community members in 2023. Aegas team isn't affiliated with further development of Gutter Cat Gang and current collection owners.

The Challenge
Duration of work: 3 months
People on the project: 8
Gutter Market was a space combining all Gutter Cat Gang collections-related trading of digital and digital-physical NFTs, handle new Gutter collection drops and establish holders community with means to launch their own collections and trade them. Combining best practices from major NFT marketplaces like Opensea, Blur, X2Y2 and LooksRare, Gutter Market provided numerous trading mechanics and had custom features such as rarity-based offers that major players didn't have at the time.
Core NFT trading was based on the early version of Seaport Protocol by Opensea. Protocol had limited user documentation at the time, and Aegas team has conducted R&D to develop new trading mechanics out of the supported basics by Seaport and contributed to Seaport protocol open-source project with robust user guide and cookbook on how to build an NFT marketplace over Seaport protocol.
