Resurrecting Crypto’s Greatest Failures with Solana's Graveyard Hackathon
74 teams rebuilt “dead” crypto ideas and proved social infrastructure can give them a second life.
Solana created the Graveyard Hackathon with a simple question: what if crypto’s failures just needed the right social layer to come back to life?
We offered Tapestry’s Protocol as the social track and 74 builders answered with extraordinary work.
What followed was a range of thoughtful experiments, real applications, and new possibilities for shared social data.
A Surprisingly Mature Track
The quality of submissions was striking.
74 projects
96% shipped GitHub repos
80% included video demos
Many were deployed and usable
Even more telling was how teams used the social graph:
77% wrote to the social graph
72% created content nodes
66% imported user profiles
54% integrated all three Tapestry primitives
Builders weren’t just experimenting, they were building real applications around shared social data.
A Taste of What People Were Building
Gaming: 29 projects
Social / Community: 13 projects
AI / Agents: 12 projects
Governance: 12 projects
Each category found a different reason to lean on social infrastructure.
Gaming used it for provable ownership and reputation. Governance projects surfaced reasoning behind votes. AI agents gained persistent identities. Social apps discovered that trust graphs work better when users actually own them.
The Winners
We judged on consumer readiness, creativity, and data contribution.
🥇 1st Place: Biotry — Research as a Social Graph
Biotry saw that scientific research is a social graph (researchers, papers, citations, funding flows) but it’s trapped in centralized databases owned by journal publishers. They brought it onchain: researchers become profiles, publications become content nodes, peer review becomes graph edges, and funding becomes a function of onchain reputation.
🥈 2nd Place: ClawdDAO — Governance with Receipts
ClawdDAO diagnosed a critical problem: ~5% voter turnout in Solana DAOs. Their answer: AI agents that internalize your governance values, vote on your behalf (through Realms), and publish their reasoning to Tapestry so you can audit every decision.
🥉 3rd Place: Umanity — Wiring the Graveyard Together
Umanity asked the meta question: what if failed concepts only failed because they were isolated? They took six things crypto declared dead (SocialFi, charity tokens, DAOs, NFTs, loyalty programs, and Blinks) and wired them together into one coherent app. The result = transparent donations, collective fund governance, and provable impact.

Honorable Mentions
Ouija: A SocialFi graveyard where users confess bad trades, press F for respect, and bond through shared failure.
sigints.club: A verification economy for real-time signals between humans and agents.
ReZero: NFTs reimagined as persistent AI agents with memory, relationships, and autonomy.
Graves are Becoming Gardens
The era of isolated, single-purpose crypto apps is over. The builders in this hackathon proved that the future is interconnected, social, and honest about the problems it’s solving. Sometimes an idea just needs more energy, and that energy comes from people interacting naturally. That’s what Tapestry can do.
Your graves are becoming gardens. Keep building.
