BuidlersBTC

100 architectural silhouettes inscribed on Bitcoin. Each one built through a sequence of analog and digital techniques: urban photography, AI-assisted retexturing, hand drawing, compressionism, vectorising and collage. 1/1 art meets pfp culture.

100 INSCRIPTIONS · 100 UNCOMMON SATS · FOREVER ONCHAIN

Created by Costo Bravo. Using the genesis Buidlings as a starting point, each Buidler is the result of a complex, sequential creative process, permanently preserved on the Bitcoin blockchain. Inscribed on uncommon sats, Buidlers are also home to the 100 Apps on Bitcoin project, bridging art and community infrastructure.

Creative instruments, data explorers, games, experiments and community tools running entirely on-chain. No centralised servers, no external APIs, no off-chain dependencies.
Built natively on Bitcoin Ordinals.

2 LIVE · 98 IN DEVELOPMENT · BUIDLER SATS

An ordinals collection where every sat holds both a work of art and an application. Free from centralised infrastructure, uncensorable and open to all, every app runs independently, exploring what updatable software on Bitcoin can be. The collection spans tooling for artists and communities, making the onchain ecosystem more approachable with every new build. Always under construction.
