## Wasm Verification

Verify that the hash of the gzipped WASM matches the proposed hash.

```
git fetch
git checkout 98eb213581b239c3829eee7076bea74acad9937b
./gitlab-ci/container/build-ic.sh -c
sha256sum ./artifacts/canisters/ledger-canister_notify-method.wasm.gz
```

## Argument Verification
```
didc encode -d rs/rosetta-api/icp_ledger/ledger.did -t '(LedgerCanisterPayload)' '(variant { Upgrade = opt record { feature_flags = opt record {icrc2 = true} } })' | xxd -r -p > ~/ledger_arg.bin
sha256sum ~/ledger_arg.bin
```
