🔐⚡ Privacy Track — Colosseum Hackathon (Powered by MagicBlock, ST MY & SNS)

Privacy is the primitive for the next generation of on-chain applications — especially in a world of autonomous agents.

This track challenges you to build privacy-first systems on Solana, powered by MagicBlock's (Private) Ephemeral Rollups & Payment API:

• Ephemeral Rollup (ER)

• Private Ephemeral Rollup (PER)

• Private Payments API

👉 Think beyond wallets and balances — build systems where data, intent, and interactions remain private by default, while still being composable and verifiable.
