Great to hear!

In particular, only now my [Capture-the-ICP hacking challenge](https://forum.dfinity.org/t/capture-the-token-hack-this-canister-for-1-icp/5159) actually works, as in order to redeem the canister’s ICP, you have to construct such a canister signature.

I wonder how long until people build transferable neurons on top of this feature (or on top of ECDSA signatures, roughly the same thing)?
