<img width="250" alt="ParaSpell logo" src="https://i.ibb.co/ZHjtZXL/214-Para-Spell-1719786844194.png">

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

## This is the current state of tools:
There are five tools from which - one is core (SDK) for the three (API, ROUTER, VISUALIZATOR). Each tool can be installed independently.

- [XCM SDK](https://github.com/paraspell/xcm-sdk): Core component for API, Router and Visualizator. Meant to unify the cross-chain experience on Polkadot and become a layer 2 protocol that allows for seamless integration of XCM into your dApps. XCM SDK groups all 54 integrated XCM-compatible Parachain XCM Pallets into one uniform package and allows you to generate cross-chain calls with just one line.
- [XCM Router](https://github.com/paraspell/xcm-tools/tree/main/packages/xcm-router): (SpellRouter☄️): Meant to allow you to create XCM calls where you receive different assets than assets you send (Eg. Send -> DOT from Polkadot, receive ASTR on Astar)—all in just one call.
- [XCM API](https://github.com/paraspell/xcm-tools/tree/main/apps/xcm-api): (LightSpell⚡️): Meant to ease the integration of XCM interoperability into your dApp, offload your dApp from heavy computing and save you costs. LightSpell implements XCM SDK and XCM Router into simple API endpoints.
- [XCM Analyser](https://github.com/paraspell/xcm-tools/tree/main/packages/xcm-analyser): Tool to convert XCM Multilocations to human-readable format. Written in emphasis on minimalistic dependency list.
- [XCM Visualizator](https://github.com/paraspell/xcm-tools/tree/main/apps/visualizator-fe): Tool to visualize XCM in the Polkadot ecosystem. Browse through history, explore selected Parachains, filter accounts engaging in XCM the most and more all in exciting 3D universe-like visualization.

## The core and the only XCM SDK you will ever need
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 our battle-hardened and well-established [XCM SDK](https://github.com/paraspell/xcm-sdk).
[![sdk](https://github.com/dudo50/dudo50/assets/55763425/4348e5e4-b4cc-4205-a890-41efc6cfac15)](https://github.com/paraspell/xcm-sdk)

### The abilities you gain by using XCM SDK:
- Ability to transfer XCM messages from/to 54 different XCM compatible Parachains (Number of compatible chains fluctuates as some of them are added/removed)
- Support for all three XCM transfer scenarios (UMP - Para to Relay, DMP - Relay to Para, HRMP - Para to Para)
- Support for multi-asset transfers and fully customizable multi-locations (for destination chains, accounts and currencies)
- Customizable XCM version (If our preselected version stops working, you can select one that works with just one simple parameter)
- Asset claim feature with reduced parameters (Only 3 parameters required - chain, amount and address)
- Polkadot <> Kusama bridge implemented for both DOT & KSM transfers
- Testing on testnet or localhost (You can input custom WS port parameter or even custom Parachain ID)
- Useful [transfer info queries](https://paraspell.github.io/docs/sdk/xcmPallet.html#xcm-transfer-info) (Query fees, expected delivery amount and other transfer-related info all in just one query)
- Front-end related data queries - useful [asset queries](https://paraspell.github.io/docs/sdk/AssetPallet.html), [XCM pallet queries](https://paraspell.github.io/docs/sdk/NodePallets.html), [existential deposit queries](https://paraspell.github.io/docs/sdk/xcmPallet.html#query-existential-deposit) and more!
- Ability to use a keep-alive kind of XCM transfer which checks the balance of the account on the destination chain and determines if the amount you send is sufficient.

**XCM SDK has since the last 9 months of maintenance had a total of 23506 downloads on NPMJS**

## Sending one asset cross-chain and receiving another was never this easy
Meet our latest state-of-the-art technology called [XCM-Router](https://github.com/paraspell/xcm-tools/tree/main/packages/xcm-router). It is easy to implement and has plenty of awesome features like automatic exchange chain selection! Featuring **524** asset exchange pools makes it the largest liquidity routing tool in the Polkadot. Try it out via [playground](https://playground.paraspell.xyz/)!

## 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/landing-page) will be fully maintained for the mentioned period starting on 1st August 2024 and ending on 1st February 2025. This proposal allows all tools to remain completely free for the entire Polkadot and Kusama communities. It also allows our team to dedicate time to help other teams that wish to implement our tools.

### What are you getting by implementing one of our tools or more
- Complex free support with implementation (Through a private telegram group between our 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 our [Landing page](https://lightspell.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
- Our products allow dApps to be created much faster, so you can enjoy their benefits quicker.
- You can be sure, that dApp implementing our tool is safe for XCM as our tools are thoroughly tested and regularly updated. There are multiple ways to lose assets cross-chain.
- You too can try our products via the [Playground](https://playground.paraspell.xyz/).
- We have 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 our tools. They are purely common good).
