## Infrastructure summary

| Item  | Cost |
| ------- | ---- |
| Servers | $2332.2 |
| Ali email service | $35.32 |
| Domains | $106.93 |
| volatility and currency translation for servers and domains | $243.92 |

Note: we paid server and domain bills with Chinese CNY, and it costed us additional fees because of currency translation and token price volatility. This is only requsted for server/domain bills, no developers payment.

## Maintenance

The maintenance work includes:
- Server deployment maintenance: daily server monitor, upgrading products versions, emergency handling, etc.
- Necessary context information collection, like dotreasury proposal/projects context collection and updation, statescan asset information.
- Collaboration with other teams to provide api support and some governance explanation.
- Codebase maintenance: code refactor, bug fixes, UI tweaks, dependency upgrading, etc.

We will list the main work for codebase maintenance by products.

### Subsquare

- Polkassembly changed its backend apis, and we'd have to change most of context syncing and comments query code.
- Support split votes for democracy referendum.
- Support OpenGov inline proposal.
- Common post detail page refactor, and common business are extracted as components.
- Remember the choice even when user don't agree with the cookie policy.
- Config eslint for next/backend/scan packages to check potential bugs with github CI.
- Fix popup and delegation items responsive scroll style.
- Add warning bar for scam proposals.
- Improve word break style for post content and remark call argument.
- Fix estimated democracy referendum executed time.
- Fix babel build configuration.
- CSS common code extraction.
- Add more react components mounted check to prevent memory leak on fronted pages.
- Fix external urls for subscan/statescan.
- Remove useless user profile query in Auth component.
- Fix toast item style.
- Fix identity icon for addresses with sub identity.
- Fix page width for some pages including empty overview page, settings page, etc.
- Disable background page scrolling when popup is shown.
- Fix theme toggle with react context, while previously we use redux.
- More than 10 times hotfixes after new version released.

Please check the [changelog](https://github.com/opensquare-network/subsquare/blob/main/CHANGELOG.md) (release 2.3.1 to 2.9.8) and [commits](https://github.com/opensquare-network/subsquare/commits/main) for more details. We will request 10 FTE equivalent work per month for subsquare, totally 60 FTE.

### Dotreasury
- Fix tip slashed business handling. There are 2 slashed ones on kusama.
- Refactor proposals/applications tab summary layout, better for responsive view.
- Add overview api for statescan.
- Fix the business in council motion rejected hook to solve the proposal invalid state bug.
- Add `isFinal` field to proposals in case of council motions handle finished proposals.
- Query and show proposal titles from subsquare if no set manually by admin.
- Update funded projects information.
- Remove semantic ui css patch because of dependency upgrading.
- Improve codebase configuration to ignore annoyning and unnecessary sourcemap warnings.
- Several times hotfix after release. Many times we found bugs, and sometimes user reported them.

Please check [commits](https://github.com/opensquare-network/dotreasury/commits/main) for more details. We will request 6 FTE equivalent work per month for dotreasury, totally 36 FTE.

### Statescan

We deprecated [statescan v1](https://github.com/opensquare-network/statescan) and developed [statescan v2](https://github.com/opensquare-network/statescan-v2). There are several reasons:
1. We want a better codebase for [visualizing polkadot bounty program](https://kusama.subsquare.io/treasury/bounty/11). The code should be more modularized and clean.
2. SSR is abandoned, because:
    - We want the page first be loaded without the affection of backend apis. 
    - Fronted code can be deployed to IPFS.
    - Better collaboration for future bounties.

The work includes:

- We migrate the statemine/statemint/westmint v1 deployments to v2 and add new deployments for kusama, collectives and westend collectives.
- We refactored the scripts to parse, fetch and sync NFT metadata. The code is splited into different modules including IPFS related utilities, parse task population, parse result syncing, etc.
- Add asset height for predefined asset information, so destroyed assets' context won't be used for existed ones.
- Fix NFT image layout and background color for better image view.
- Remove all count for extrinsics/events list api for performance. The all documents count require a full DB table scan, so it's extremely slow.
- Test and add more database indexes for better performance.
- Blockmeta scan for collectives para-chain. 
- A [monitor api](https://status.statescan.io/) is created to fast track all chains scan status.
- A [lark](https://www.larksuite.com/) bot is created to report the scan failure. OpenSquare team use lark for daily collaboration work and this bot can reach us well.
- Support video NFTs, including metadata parse and fronted site rendering.
- Remove scemantic UI from dependency.
- Add lint and github CI configuration for backend packages.

Please check [commits](https://github.com/opensquare-network/statescan-v2/commits/main) for more details. We will request 7 FTE equivalent work per month for statescan, totally 42 FTE. Note our request is higher than previous request because the statescan v2 really cost more devops, design and hotfix work.
