Development

Referendum detail page enhancements

• Statistics on referendum detail page.
• DV vote status under the votes bubble.
• Deciding & confirming information enhancement.
• Call view enhancement and information extraction.
• Kill/Cancel a referendum.
• Stable coin support.
• comments filter.

Referenda track status page

Each track is a referenda queue for the community decision, and each track has its capacity and other properties. We created a track status page to visualize how track works and their status. Check here for the tracks status page.

New referenda and templates

It will be very easy for the community to create new referenda on subsquare with this feature. Users can first create preimages and then create referenda. We also developed several templates which can help users quickly create new referenda. Currently the templates include:

• local treasury spend
• stable coin treasury spend
• remark
• kill/cancel a referendum

Preimages management

Preimages are basic elements for governance and other on chain actions. Subsquare preimages feature includes:

• A list to show all on chain preimages
• An user can filter out a preimage by its hash
• A connected user can filter out preimages with his own deposits.
• A connected user can create a preimage by composing an extrinsic or by filling a template.
• A connected user can unnote a preimage with his deposit.

Work also includes the support for pallet preimage updates, for example this update.

Account and profile page enhancements

On the first release of the account/profile page, users can manage their votes or see other accounts' votes. We developed more features so users can check more information of their accounts.

• Deposits management. Subsquare will check and show deposits by referenda, fellowship, democracy, treasury, identity, and preimages. Users can also remove these deposits when available.
• Delegation status. Users can see their received delegations and delegations to others.
• Users can check their history transfers on their profile page.
• Users can check their identity history(timeline) on their profile page.

Treasury spends and multi assets treasury support

Treasury spends are another way which is different from proposals and bounties. A treasury spend can spend any assets in polkadot via XCM. After approval by a referendum, a spend will be created. The beneficiary can claim the fund in a predefined limited time or the spend will become expired.

The work includes:

• Scan scripts which scan related business, extract data and save them to the database.
• Backend APIs to serve treasury spends business data.
• A spend list page which shows all treasury spends and their basic properties including requested token and amount, propose, title, etc.
• Treasury spend detail page on which
  • We can see the binded referendum and corresponding comments.
  • Requested fund details.
  • Valid and expiration visualization(countdown components).
  • Timeline.
  • A payout button with which users can claim the fund.

Assethub basic features

These features will help users manage their assets on assethub. With these features, users can:

• See all their assets and balances.
• Transfer their assets.
• See transfer history.
• Check all on chain active assets.
• See any other address' assets on the profile page.

Bounty enhancement

New features include:

• Show bounty curator. If the curator address is a proxy or multisig address, we will show the proxied and multisig signatories addresses.
• Support creating a new child bounty. It can work with mimir if the curator is controlled by a multisig address.
• Support proposing a curator on child bounty.
• Support accepting curator on parent/child bounty.
• Support claiming a parent bounty.

Q&As

1. What's your plans?

Subsquare will be a full-featured dapp for polkadot. It will help the community to understand polkadot, track polkadot status and perform actions on polkadot. Our next concrete plans includes identity, more discussion data decentralization features, proxy/multisig enhancement, coretime, etc. We are also doing research about quadratic funding and trying to figure out a solution for the polkadot ecosystem.

2. How many users are using subsquare?

We didn't collect user data, so we didn't know the exact aggregated user numbers. Currently, our monthy unique visitors are about 175K and daily unique visitors are 10k.
