+### [Aztec.nr] get_public_key oracle replaced with get_ivpk_m
+
+When implementing changes according to a [new key scheme](https://yp-aztec.netlify.app/docs/addresses-and-keys/keys) we had to change oracles.
+What used to be called encryption public key is now master incoming viewing public key.
+
+```diff
+- use dep::aztec::oracles::get_public_key::get_public_key;
++ use dep::aztec::keys::getters::get_ivpk_m;
+
+- let encryption_pub_key = get_public_key(self.owner);
++ let ivpk_m = get_ivpk_m(context, self.owner);
+```
