TEEs are vulnerable to side channel attacks. The Secure Enclave’s private key can be extracted. Once again, wasted work in the wrong direction!

Huge milestone for Cashu.

After 3 years of work, we finally have unruggable mints.

I'm testing the first on-chain Cashu mint running inside a Trusted Execution Environment (TEE), where the mint keys are generated entirely within the enclave and remain unknown to the operator.

That means the operator cannot inflate the ecash supply and cannot access the Bitcoin reserves backing it.

We've moved from trusting operators to relying on hardware-enforced cryptographic guarantees.

There's still work to do, but the path forward is clear. This is an incredibly exciting step toward trust-minimized ecash.
