Built MultiStract over the weekend with my teammate Thijs for the
#Fidelity - sponsored by
#Solana hackathon - and we ended up taking 2nd place 🏆
MultiStract explores crypto-agility for digital asset custody in a post-quantum future.
#Algorand is implemented and was the blueprint. ✅
The core idea:
if foundational cryptography used across blockchain ecosystems were ever compromised, custody infrastructure should be able to adapt without rebuilding the entire application layer.
We explored cross-chain abstractions, post-quantum authorization models, and how different ecosystems may evolve toward PQ-secure asset movement over time.
Because this was built for a closed-source/private hackathon, we can’t share implementation details or the repository publicly right now, but excited to talk more about the broader ideas and research direction soon. 💚
