<h2 id="asetofcommongoodxcmtools">A set of common good XCM tools.</h2>
<h2 id="thisisthecurrentstateoftools">This is the current state of tools:</h2>
<p>There are three tools from which - one is core for the other two. Each tool can be installed independently.</p>
<ul>
<li><a href="https://github.com/paraspell/xcm-sdk">XCM SDK</a>: Core component for both API and Router. 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 50 integrated XCM-compatible Parachain XCM Pallets into one uniform package and allows you to generate cross-chain calls with just one line.</li>
<li><a href="https://github.com/paraspell/xcm-api">XCM API</a>: (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 into simple API endpoints.</li>
<li><a href="https://github.com/paraspell/xcm-router">XCM Router</a>: (SpellRouter☄️): Meant to allow you to create XCM calls where you receive different assets than assets you send (Eg. Send -&gt; DOT from Polkadot, receive ASTR on Astar)&mdash;all in just one call.</li>
</ul>
<h2 id="thecoreandtheonlyxcmsdkyouwilleverneed">The core and the only XCM SDK you will ever need</h2>
<p>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 <a href="https://github.com/paraspell/xcm-sdk">XCM SDK</a>.</p>
<p><a href="https://github.com/paraspell/xcm-sdk"><img src="https://github.com/dudo50/dudo50/assets/55763425/4348e5e4-b4cc-4205-a890-41efc6cfac15" alt="sdk" /></a></p>
<h3 id="theabilitiesyougainbyusingxcmsdk">The abilities you gain by using XCM SDK:</h3>
<ul>
<li>Ability to transfer XCM messages from/to 50 different XCM compatible Parachains (Number of compatible chains fluctuates as some of them are added/removed)</li>
<li>Support for all three XCM transfer scenarios (UMP - Para to Relay, DMP - Relay to Para, HRMP - Para to Para)</li>
<li>Testing on testnet or localhost (You can input custom API parameter or even custom Parachain ID)</li>
<li>Useful asset queries, XCM pallet queries, minimal deposit queries and more!</li>
<li>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.</li>
</ul>
<p><strong>XCM SDK has since the last 4 months of maintenance had a total of 7.287 downloads on NPMJS</strong></p>

XCM ROUTER, XCM API & XCM SDK 5 months of maintenance and server cost coverage proposal

General

Problem Statement:
- The current state of XCM tools in the Polkadot and Kusama ecosystem is fragmented, with multiple independent tools that can be installed separately.

Significance:
- The proposed ParaSpell tools, including XCM SDK, XCM API, and XCM Router, aim to unify the cross-chain experience and provide seamless integration of XCM into dApps.
- XCM SDK has been downloaded 7,287 times in the last 4 months, XCM API has served 126,782 requests without downtime in 142 days, and XCM Router has been downloaded 1,826 times in 49 days.

Proposed Solution:
- ParaSpell offers XCM SDK as the core component, which unifies the XCM experience and allows for cross-chain calls with just one line of code.
- XCM API provides simplified integration of XCM interoperability into dApps, offloading heavy computing and saving costs.
- XCM Router enables easy cross-chain asset transfers and automatic exchange chain selection.

Expected Outcomes:
- Developers gain the ability to transfer assets cross-chain, exchange them for another asset, and hide the complexity of asset exchange.
- Users benefit from faster dApp development, safe implementation of XCM tools, and access to playgrounds for testing.
- The proposal seeks $30,000 in funding for 5 months of maintenance tasks and assistance to other teams.
