## Dear Kusama community,

##  Meet ParaSpell:

![ParaSpell logo](https://user-images.githubusercontent.com/55763425/251588903-bcf72b05-bdf7-46d8-b804-16b0e3236792.png)

## A set of powerful XCM Tools ready to elevate your project cross-chain experience.

### What is [ParaSpell](https://paraspell.xyz) currently working on full-time:

-   [**XCM SDK**](https://github.com/paraspell/xcm-tools/tree/main/packages/sdk): The core of ParaSpell - library making your dApp achieve interoperability within seconds. Simple to use, well-documented, and continuously improved by daily refactors for better performance and efficiency.
-   [**XCM API**](https://github.com/paraspell/xcm-tools/tree/main/apps/xcm-api): Everything that XCM SDK offers but without need to install anything or compromise on anything! Getting cross-chain capability in a package-less way was never this easy. Suitable for applications where space is everything. And when response speed also matters you can deploy XCM API to your own server as well!
-   [**XCM Router**](https://github.com/paraspell/xcm-tools/tree/main/packages/xcm-router): Send different asset than you receive. Cross-chain exchanges within one line now possible.
-   [**XCM Analyser**](https://github.com/paraspell/xcm-tools/tree/main/packages/xcm-analyser): Decode complex XCM junctions or entire XCM Calls with ease. A minimalistic library without heavy dependencies.
-   [**XCM Visualizator**](https://github.com/paraspell/xcm-tools/tree/main/apps/visualizator-fe): A stunning 3D Universe-like Visualization of XCM. Browse through XCM history, explore selected Parachains, download selected graphs and data, filter accounts engaging in XCM the most, and much more.
-   **A full tool overview is also available on the new ParaSpell** [**landing page**](https://paraspell.xyz)**.**

## The XCM SDK that just works.

Created when there were no other SDKs for XCM in the ecosystem. At the sole beginning of Polkadot. Born from a wild idea to unify the XCM experience in the ecosystem. Meet battle-hardened and well-established XCM SDK.

![sdk](https://github.com/user-attachments/assets/9b0c8c15-df8c-482e-86d0-8e2bbee87556)

### What the XCM SDK Provides:

-   🥇 First SDK to also support the **PAPI** package. Supporting both Polkadot API and PolkadotJS. Users can easily choose whether to use **PAPI** or **PJS**.
-   API Failsafe mechanisms (API endpoint doesn't work? No worries, SDK automatically switches to the next working one!)
-   XCM DRY Running (DRY RUN your XCM messages and find out whether they will execute without wasting resources and potentially risking asset loss!)
-   Ability to transfer XCM messages from/to **58** different XCM compatible Parachains & Relay chains (Number of compatible chains fluctuates as some of them are added/removed)
-   Support for ecosystem bridges such as **Polkadot<>Kusama bridge** or **Polkadot<>Ethereum** (Snowbridge)
-   All three XCM transfer scenarios in one line (**UMP** - Para to Relay, **DMP** - Relay to Para, **HRMP** - Para to Para)
-   Multiple choices for asset selection - id, symbol, multilocation, multiasset selection
-   Customizable XCM version (If preselected version stops working, you can select one that works with just one simple parameter)
-   Testing on testnet or localhost (You can input custom WS port parameter or even custom Parachain ID)
-   There are multiple important Asset queries for the front end, such as **getExistentialDeposit**, **getOriginFeeDetails**, **getAssetBalance**, **getTransferrableBalance,** and **getTransferInfo,** which query asset and balance data directly from the chain of your choice.
-   Other front-end-related data queries, such as XCM Pallet support queries, Asset support queries, and more (all of these are instant because they are in the SDK map).
-   XCM Batch transfers (Send multiple XCM messages at once)

**XCM SDK has, since it was introduced 835 days ago (September 25th. 2022) had a total [73477](https://npm-stat.com/charts.html?package=%40paraspell%2Fsdk&from=2022-01-25&to=2025-01-07) of downloads on NPMJS**

## ParaSpell's Team and history:

-   By now, we completed 6 Web 3 Foundation grants meant to fund the development of ParaSpell's common good tools. This goes to show our dedication to the topic and the community. They can be observed here: [Phase 1](https://github.com/w3f/Grants-Program/pull/1118), [Phase 2](https://github.com/w3f/Grants-Program/pull/1245), [Phase 3](https://github.com/w3f/Grants-Program/pull/1589), [Phase 4](https://github.com/w3f/Grants-Program/pull/1817) and [Phase 5](https://github.com/w3f/Grants-Program/pull/2057). We are also pushing development onwards in other cross-chain topics in the ecosystem. For example, the [xcNFT pallet](https://paraspell-research.github.io/xcnft-docs/) meant to allow users to **transfer NFTs** through XCM - [Link](https://github.com/w3f/Grants-Program/pull/2358).
-   We have been granted trust from the Kusama community multiple times in the following maintenance proposals that helped us further perfect XCM Tools: [Maintenance 1](../referenda/277), [Maintenance 2](../referenda/344) and [Maintenance 3](../referenda/417). [Maintenance 2](../referenda/344) is also historically 🥇first maintenance-related referenda to receive **100% AYE support** for which we are very thankful!
-   Some of XCM Tools are partially / fully funded by participation in Hackathons (To maximize self-sufficiency when developing state-of-the-art tools).
-   XCM API was co-funded with 🥇first place at the Polkadot Global Series APAC 2023 Hackathon in the XCM Integration track.

### The team behind the project has been hacking in the Polkadot ecosystem for a while now.

Consisting of 2 members:

-   Dušan Morháč: [PBA 2023 Buenos Aires Alumni](https://singular.app/collectibles/statemine/20/12), Building in ecosystem since 2021, [LINKEDIN](https://www.linkedin.com/in/dudo50/), [GITHUB](https://github.com/dudo50).
-   Michael Absolon: Typescript expert with 4 years of professional experience, Building in the ecosystem since 2022, [LINKEDIN](https://www.linkedin.com/in/michael--absolon/), [GITHUB](https://github.com/michaeldev5).

Both team members achieved their Master's degree recently (June 2024) and are working on ParaSpell full-time. Dušan continues to study for a Doctoral degree (To be able to continue research passion and release more research papers for Polkadot and ParaSpell). Michael is registered into for PBA X and in-person PBA Campus 2025.

## Aim of this proposal:

The proposal aims to aid server costs and maintenance for the 🥇 first [XCM API](https://github.com/paraspell/xcm-tools/tree/main/apps/xcm-api) and [XCM Visualizator](https://github.com/paraspell/xcm-tools/tree/main/apps/visualizator-fe) in the Polkadot and Kusama ecosystem. Maintaining XCM API, [XCM ROUTER](https://github.com/paraspell/xcm-tools/tree/main/packages/xcm-router) and XCM Visualizator also include maintaining its core component - [XCM SDK](https://github.com/paraspell/xcm-sdk). These common good tools along with [XCM Analyser](https://github.com/paraspell/xcm-tools/tree/main/packages/xcm-analyser), [XCM Playground](https://github.com/paraspell/xcm-tools/tree/main/apps/playground), [Documentation](https://github.com/paraspell/docs) and [Landing page](https://github.com/paraspell/xcm-tools/tree/main/apps/site) will be fully maintained for the mentioned period starting on 1st February 2025 and ending on 1st August 2025. This proposal allows all tools to remain completely free for the entire Polkadot and Kusama communities. It also allows ParaSpell team to dedicate time to help other teams that wish to implement XCM Tools.

### What are you getting by implementing one of ParaSpell's XCM Tools or more

-   Complex free support with implementation (Through a private telegram group between ParaSpell's team and your team (We usually respond within minutes and we are also open to live calls when time plays a role in your project delivery - form to reach out to us can be found on ParaSpell's [Landing page](https://paraspell.xyz/)))
-   Prompt issue solving if any occurs (Feel free to open an issue in any repo)
-   Constant updates for every package (We strive to bring new features for each tool)
-   Comprehensive [documentation](https://paraspell.github.io/docs/) for each tool
-   Reliability (Checked each month for changes in Pallets or compatible Parachains)
-   **Guarantee, that everything is free for everyone. The ParaSpell✨ team aims to deliver only the common good, be completely open-source and free with no hidden costs or subscriptions.**

### What are you getting as a non-developer/dApp user by supporting this proposal

-   XCM tools allow dApps to be created much faster, so you can enjoy their benefits quicker.
-   You can be sure, that dApp implementing XCM tools is safe for XCM as XCM Tools are thoroughly tested and regularly updated. There are multiple ways to lose assets cross-chain.
-   You, too, can try XCM Tools via the [Playground](https://playground.paraspell.xyz/).
-   The XCM Tools team has been in the ecosystem for a while now, and we are hardcore ecosystem fans. We will continue maintaining the tools even if we are short of funding (Just at a slower pace). So you do not have to deal with your dApp suddenly disabling your favourite feature. This is because we primarily build and maintain these tools to make life easier for everyone - not for profits (There is no business model or hidden fees in any of ParaSpell's XCM Tools. They are purely common good).

## Proposal schedule

-   Discussion: 7. January. 2025 - 13. January. 2025
-   Voting: 14. January. 2025 - 28. January. 2025

## Proposal ask

The proposal seeks 45.990$ worth of funding for 6 months of various maintenance tasks, research, and improvement tasks, as well as assistance to other teams. This is divided into 7.665$ per month and 23,95$ per developer work hour (A decrease of 2000$ from the previous proposal because research articles are now fully covered by the faculty where Dušan studies). More information can be found in the full proposal document.
