Privacy is the primitive. Speed is the catalyst. Build without compromise.

Unlink lets you build compliant private applications on any public blockchain in 5 lines of code.


Monad is the fastest EVM chain with over 10,000 TPS.

Why?

Public blockchains unlocked programmable money and global settlement. But they made everything public, and that breaks how the real world operates. No individual or company will put their entire life on a public ledger.

Privacy isn't a feature. It's the prerequisite. But privacy alone isn't enough. Confidential transactions need to settle fast enough for the real world to rely on them. The infrastructure has to be both private and performant. Build with the tools making it possible.
