1️⃣ Connecting Privacy Systems Across Different Chains
Each partner ecosystem (Starknet, Arcium, Aztec, Zcash, Osmosis, Axelar, FHENIX) uses its own cryptography, account model, and transaction format.
I built bridge adapters to translate shielded commitments and intents between them.

2️⃣ Maintaining Privacy During Cross-Chain Execution
Even when values are hidden, metadata leaks (timing, routing, bridge hops) can reveal identity.
I fixed this using encrypted intents, randomized relayers, and delayed reveal logic.

3️⃣ Secure Self-Custody With Multichain Support
Wallets like Zashi, Unstoppable, and Noah all manage keys differently.
I implemented a unified key abstraction layer so users keep full control without breaking privacy.

4️⃣ Private AI Computation Without Trusting a Backend
Running AI on private data typically requires exposing it somewhere.
I solved this using distributed private compute Arcium to keep user data encrypted end-to-end.

5️⃣ Private DeFi Liquidity Without Breaking UX
Shielded swaps and trading often feel slow or complex.
I optimized ZK circuits and added intent batching to make private transactions feel as fast as normal swaps.

The real difficulty wasn’t adding privacy…
It was making privacy usable, fast, and interoperable across chains.
