[34r7h]

This PR adds the XMBL grant application for a decentralized media content management and distribution platform built on Substrate.

Summary

XMBL is a Substrate-based blockchain solution for content creation, distribution, and monetization in the Web3 ecosystem. The platform provides decentralized infrastructure for media content management with cross-chain interoperability through Polkadot.

Application Details

• Level: 2
• Team: XMBL
• Focus: Content management pallets, creator economics, licensing, and XCM integration

The application includes detailed technical specifications, roadmap with 2 milestones, and comprehensive ecosystem fit analysis.

Grant Level

Application Checklist

• The application template has been copied and aptly renamed (XMBL.md).
• I have read the application guidelines.
• Payment details have been provided (Polkadot AssetHub (USDC & DOT) address in the application and bank details via email, if applicable).
• I understand that an agreed upon percentage of each milestone will be paid in vested DOT, to the Polkadot address listed in the application.
• I am aware that, in order to receive a grant, I (and the entity I represent) have to successfully complete a KYC/KYB check.
• The software delivered for this grant will be released under an open-source license specified in the application.
• The initial PR contains only one commit (squash and force-push if needed).
• The grant will only be announced once the first milestone has been accepted (see the announcement guidelines).
• I prefer the discussion of this application to take place in a private Element/Matrix channel. My username is: @_______:matrix.org (change the homeserver if you use a different one)

Hi @34r7h, thank you for the application and the effort you have put into it. However, the Web3 Foundation has decided to shut down the Grants Program. Therefore, we are not accepting any new applications.
