We believe all polkadot community members expect the parachains will boom the ecosystem, while fungible assets and DeFi maybe the most important part. We're looking forward some assets like USDT maybe issued on statemine, and we can also see some teams tried to issue some test assets on Rococo#statemint. 

Then we need an explorer to check our history transfers, our issued asset lifecycle, learn some assets statistics, etc. StateScan is an explorer for it, and we began to develop it about 2 weeks ago. You can check [https://test.statescan.io](https://test.statescan.io) for our current development status. It's a development version link, but you can see current features it support. Generally they are asset list/detail, block/extrinsic/address detail. We are proposing a treasury spend to improve StateScan and so we can bring more features.

## Work in this proposal

### 1. Unfinalized blocks and asset businesses handling
Currently we handle only finalized blocks. We have to handle the unfinalized ones to help user see the latest extrinsic status and some other unsettled businesses like the transfers.

### 2. Asset lifecycle
Here we record the create, issuance, mint, destroy events, and make the asset's lifecycle.

### 3. Make the site SSR
Currently the front site is made with create-react-app.  We want to improve the user's experience with server side rendering and user don't have to see the initial spinner loading before the expected data.

### 4. Block/extrinsic/event list pages
### 5. Block/extrinsic/event/address/asset detail page create or polish
### 6. Asset statistics like holders trend, transfers amount/count trend, etc
### 7. Cross chain assets transfer records
### 8. Statemine implementation

## Possible future work
- Identity scan and view. It depends on the statemint chain identity policy. We will scan the relay chain identity if statemint use the relay chain's identity.
- Assets price tracker and assets info(like icon, team, site) collect.

## Time and cost

4 developers and 1 designer will work on this proposal, and we will request about 3 weeks equivalent cost. Cost list:
1. 4 developers and 1 designer: $5000 * 4 + $3000 = $23,000
2. Server fee: dotreasury will share the server for current stage, so $0.

So final cost is $23,000. We will calc the KSM count with the MA30 price at the onchain propose time if councilors have no problems.

## Delivery
- Will release it to statescan.io continually.
- Will make it open source.
- Will try to finish the work in 6 weeks.
