Following are the recent discussions of XCQ
[XCM as a Standard for Reading And Interacting with Parachains - #19 by gavofyork,](https://forum.polkadot.network/t/xcm-as-a-standard-for-reading-and-interacting-with-parachains/266/19) and [Polkadot forum discussion of XCQ](https://forum.polkadot.network/t/cross-consensus-query-language-xcq/7583), with all the positive comments, we would like to move onto the next phase, to have treasury's funding support in making this happen.

Cross-consensus Query Language or XCQ, is the missing piece to enable a lot of utilities that currently lacks with XCM alone.

Example use cases (more in our full proposal [here](https://docs.google.com/document/d/11c0-t0S5WbVLpoonh24OgadcK4X35_I1Q0HKpxKxLBk/edit?usp=sharing)):

- Query balances of an account
- Query the weight and fee of a particular XCM
- Query if a certain feature / pallet is available
- Implement decentralized staking pool from a parachain
- Use XCQ to query staking rewards from relaychain
- Use XCQ to query weights and fees for related operations
- Automatically purchase coretime from broker chain
- Use XCQ to query market information
- Use XCQ to query weights and fees for related operations

XCQ employs a extension based design, above features are developed as extensions and new features can be added later on as extensions too, all without changing to the core XCQ protocol.

With these XCQ queriable informaiton, it will greatly enhance UX of XCM bridge UIs, wallets, universal dApps in the ecosystem, and more as list of extensions grows.

We would like to open this discussion for other use cases (i.e. extensions) you would like to see, if it has enough support we will add them to the list too.

Proposal: Funding for Design and Development of XCQ, the Cross-Consensus Query Language

Treasury

This proposal is a top-up for the remaining funds of REF #631 which was underpaid by 28.9% due to the fluctuation of DOT.

Maintenance of public RPC and boot node services supporting the Polkadot and Kusama relay chains, system parachains, and testnets.

- **Problem Statement:** Seeking treasury funding support to develop Cross-consensus Query Language (XCQ) to enhance utilities lacking with XCM alone.
- **Significance:** XCQ enables querying balances, fees, features, staking rewards, and market information across parachains and relaychains, improving user experience and expanding dApp functionalities.
- **Proposed Solution:** Develop XCQ with extension-based design to add features without altering the core protocol.
- **Expected Outcomes:** Enhanced UX for XCM bridge UIs, wallets, and dApps, with potential for additional extensions based on community support.
