+todos:
+
+- more checks:
+    - general/fsp:
+        - [ ] check if addresses (submit, signature, sign) have enough tokens for gas
+            - [ ] collect fast updates addresses and check them too
+        - [ ] check for unclaimed rewards
+        - [ ] check for registration:
+            - [ ] aggresively report failure to register after X minutes of registration window
+            - [ ] include preregistration as well
+        - [ ] check if transactions are being made against correct contracts (eg.: what if relay contract switches)
+        - [ ] check if transactions are being made but were sent too early or too late
+    - staking:
+        - [ ] check node uptime
+    - ftso:
+        - [ ] better ftso value analysis 
+            - weird value (not just None but also 0.1 all the time, or just wildly different to median)
+            - parse events to be able to tell feeds by names not by indices
+        - [ ] check submit signatures signature against finalization 
+    - fdc:
+        - [ ] correct bitvote length (submit2 fdc)
+        - [ ] check submit signatures signature against finalization 
+    - fast updates:
+        - [ ] recover signature from fast updates and check if updates are being made 
+        - [ ] check if length of update is correct
+- push notification scheme:
+    - we need a general-ish extnesible framework to add more notification plugins
+    - notification plugins
+        - [x] stdout logging
+        - [x] discord
+        - [ ] slack
