## Enable `pzp6e` to sign with `ecdsa:secp256r1:key_1`

The resharing of the tECDSA secp256r1 master key from subnet `pzp6e` to `uzr34` as described above was successful.

A new [proposal](https://nns.ic0.app/proposal/?proposal=144490) has been submitted to enable this key for signing on fiduciary subnet `pzp6e`, which is already the signing subnet for the existing master keys.
