SubSquare is a governance platform for substrate based blockchains, and we have been continually maintaining the deployments for Hydration. We propose a treasury spend to support the work.

## Work scope

Our request will cover:
- Labor cost for daily monitor to keep the deployment well running.
- Infrastructure including servers, email services cost.
- New release deployments.
- UI tweaks and bug fixes related to hydration.
- Customized development.

Customized features include:
- Extract EVM contracts calls and show them on the referendum detail page.
- Add Hollar stable coin treasury spend template for referenda and preimages.

We won't request new common features development from para chain teams since most of them are funded by the polkadot/kusama treasury. Part of them include:
- OpenGov referenda actions.
- Search feature enhancement.
- Multisig support.
- Show voters on referendum page curve chart, so users can see voters' affection.
- Show gas and nonce on some extrinsic signing popups.
