Privacy projectHinkal: Private DeFi layer. Technology: zero-knowledge proofs.
Hinkal took shielded balances further than most, letting users hold assets privately and then deploy them directly inside DeFi protocols across several chains, rather than shielding transfers alone. An access check put compliance in front of the pool rather than after it. In July 2026 an exploit drained roughly 820 thousand dollars, close to the value locked in the protocol at the time, and no post-mortem has been published since. Listed here for completeness of the map.

What is zero-knowledge proofs?
One party proves a statement about hidden data is true without revealing the data the statement is about.
How it compares with the other approaches on latency, trust assumptions and fit is set out, with sources, in the technology taxonomy.
Private by design.
