1/1 Continuum Art 📆

Some Partner Artists such as Costo Bravo, Smiley Bits, Milla Si and Viola Misscode as well as Lemonhaze (sold out), were amongst the 91 artists who contributed to the Continuum calendar and have released the artworks they created for it as unique 1/1 pieces on BTC, now available to collect on Gamma. These seasonal works, spanning photography, painting, generative, and pixel art, are part of a larger vision that began in February—to bridge digital and physical art while creating something timeless.

That vision became Continuum: a perpetual daily calendar featuring 366 unique artworks by 91 Gamma Partner Artists, each contributing four pieces spread across the seasons. Printed on museum-grade art paper and designed to last decades, Continuum is more than a calendar—it’s a collectible, a daily ritual, and a lasting piece of art.

You can now bid for a chance to collect the physical calendar through our newly launched Signals platform, where early supporters gain access to exclusive rewards, discounts, and limited-edition bonuses.

Gutter Cat Gang on Bitcoin 😼

Launched in June 2021, Gutter Cat Gang (GCG) is one of the most iconic and culturally influential NFT collections born on the Ethereum blockchain. With a gritty, street-smart aesthetic and a narrative rooted in the Gutter—a post-apocalyptic, cyberpunk world of survival and community—GCG quickly stood out as a lifestyle- and identity-driven Web3 brand. Known for real-world collaborations with brands like Puma and the Detroit Pistons, GCG blended Web3 with sports, fashion, and IRL events. On June 11, 2025, Doggtor took ownership of the project and has been rebuilding and evolving the brand with a focus on transparency, creative expansion, and cross-chain innovation—including the upcoming GCG-Legends drop on Bitcoin Ordinals. 100 curated 1 of 1s with the help of Ordinals OG Karmelo.

Gutter Legends - Launching on Gamma soon.

Partner of the Week 👩‍🎨

For Sepim, art has never been just a career—it’s been a journey of transformation. A full-time physical painter for over a decade, her transition into digital art began in February 2022 when she entered the NFT space. She started minting her work on platforms like OpenSea, KnownOrigin, Foundation, and Exchange.art, exploring both Ethereum and Solana. But it was an open call that introduced her to the Bitcoin art community, and it changed everything. “I received so much love from the Bitcoin family,” she recalls. “They care deeply about real art—your story, your style, your technique.” For Sepim, that level of authenticity and appreciation was what she’d been searching for all along.

A Focus on Leo Cats 😻

Launched in December 2023, $LEO is a memecoin named after the pet cat of Muneeb, the founder of the Stacks blockchain.

Over the past 20 months, Leo has grown into one of the most active, if not the most active communities on Stacks, with over 12,500 holders and the highest volume and liquidity of any memecoin on the network. It reached a $30M all-time high in March 2024 and became only the second Stacks token listed on MEXC. The team also launched stxtools.io, a popular analytics platform, and in August, the Leo Cats NFT collection on Gamma, which sold out in hours. With 3,200+ unique holders and strong secondary market activity, Leo Cats ranks among the top PFP collections on Stacks. Through regular giveaways, whitelist perks, and high-value collaborations like the Pizza Pets airdrop, Leo continues to drive momentum across the Stacks ecosystem.
