## Candid Post Upgrade Args
```candid
(record { governance_canister_id = principal "rrkah-fqaaa-aaaaa-aaaaq-cai"; ledger_canister_id = principal "ryjl3-tyaaa-aaaaa-aaaba-cai"; exchange_rate_canister = opt variant { Set = principal "uf6dk-hyaaa-aaaaq-qaaaq-cai" } })
```
### Validating Candid Args
Verify that the hash of the args matches proposal contents.
`didc encode '(record { governance_canister_id = principal "rrkah-fqaaa-aaaaa-aaaaq-cai"; ledger_canister_id = principal "ryjl3-tyaaa-aaaaa-aaaba-cai"; exchange_rate_canister = opt variant { Set = principal "uf6dk-hyaaa-aaaaq-qaaaq-cai" } })' | xxd -r -p | sha256sum`
## Wasm Verification
Verify that the hash of the gzipped WASM matches the proposed hash.
```
git fetch
git checkout 2ef275ecee0b8e2e6eba06d13ff4585ba8957f2e
./gitlab-ci/container/build-ic.sh -c
