## Features & Fixes

###  Fixed

Fix an issue occurring when the NNS Governance cannot find proposals corresponding the creation
of the SNS for which Neurons' Fund participation confirmation is required during finalization. Note
that currently, new SNSs that do not even request Neurons' Fund participation are potentially
risking that their finalization halts if the NNS proposal that created that SNS cannot be found
(this recently happened due to an
[unrelated problem in the NNS](https://forum.dfinity.org/t/nns-governance-bug-in-proposal-136693/48224)).

The solution is to avoid calling the NNS Governance's `Swap.settle_neurons_fund_participation_result`
function if the SNS does not specifically request Neurons' Fund participation.
[More details](https://forum.dfinity.org/t/taco-dao-sns-finalization-temporarily-halted/48846).

## Wasm Verification

See the general instructions on [how to verify] proposals like this. A "quick
start" guide is provided here.

[how to verify]: https://github.com/dfinity/ic/tree/b3d031ec7efff83f033adaeb80c04dec0537d0bc/rs/nervous_system/docs/proposal_verification.md

See ["Building the code"][prereqs] for prerequisites.

[prereqs]: https://github.com/dfinity/ic/tree/b3d031ec7efff83f033adaeb80c04dec0537d0bc/README.adoc#building-the-code

```
# 1. Get a copy of the code.
git clone git@github.com:dfinity/ic.git
cd ic
# Or, if you already have a copy of the ic repo,
git fetch
git checkout b3d031ec7efff83f033adaeb80c04dec0537d0bc

# 2. Build canisters.
./ci/container/build-ic.sh -c

# 3. Fingerprint the result.
sha256sum ./artifacts/canisters/sns-swap-canister.wasm.gz
```

This should match `wasm` field of this proposal.
