ParaSpell✨ XCM Tools - Maintenance & Server cost coverage Q1 & Q2 2025
Dear Kusama community,
Meet ParaSpell:
A set of powerful XCM Tools ready to elevate your project cross-chain experience.
What is ParaSpell currently working on full-time:
- XCM 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: 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: Send different asset than you receive. Cross-chain exchanges within one line now possible.
- XCM Analyser: Decode complex XCM junctions or entire XCM Calls with ease. A minimalistic library without heavy dependencies.
- XCM Visualizator: 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.
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.
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 of downloads on NPMJS
Want to go packageless and save space? We got you
Meet award-winning and 🥇 first XCM API in the ecosystem. XCM API packs every XCM SDK feature and allows you to implement XCM packagelessly.
Unable to decide? A couple of why XCM API might be the right way for your project:
- Built-in Token authentication for DDoS prevention (No authentification required for up to 100 req/min)
- Designed for simple private deployment (Need faster responses? Have servers that are faster? Feel free to deploy API yourself! You can also build business models on top of this when there are other projects needing faster responses. Opportunities are limitless).
- XCM API Offloads your server from computing required to construct calls (You receive constructed message already)
- You save server costs!
- Package-less integration (No need to install anything compared to SDK alternatives)
- Simple to implement (Constructed to be as dev-friendly as possible)
- It is free for everyone to request more requests per minute!
XCM API Served since its launch 482 days ago (September 13th. 2023) a total of 729791 requests and faced 0 downtime
