When we started MSquared, our ambition always went far beyond creating immersive virtual worlds. We aimed to reshape the metaverse, creating an extension of the internet where users are not locked into one platform; instead, identities and assets can move across virtual worlds.
While some progress has been made across the industry, most solutions remain surface-level or isolated to specific platforms. The kind of deep, functional interoperability needed to unlock truly composable worlds has yet to be realised at scale.
As fans of The Sandbox, we have released another open source experiment, a lightweight converter that wraps Sandbox avatars in Metaverse Markup Language (MML). This tool lets creators and collectors use their Sandbox assets into any world that supports MML custom characters, showing in practice how cross platform interoperability can work. It is one of many proof of concept projects we are building to test ideas, gather feedback, and move the open metaverse from vision to reality.
We’ve deliberately shared this as an open-source experiment, inviting the community to test, fork, and build upon it. But while it opens creative possibilities, it also highlights the need for broader systems of trust. Right now, the tool does not verify NFT ownership, meaning that in theory, anyone could convert and use a Sandbox avatar they don’t own.
This is where moderation and protocol design come in. As we expand MSquared’s infrastructure, tools like Atlas, our asset indexing and classification system can play a critical role in verifying source, enforcing rules, and supporting takedown requests when needed.If you’re a member of The Sandbox community, it's really easy to get started: Check out the converter on GitHub , wrap your avatar, then load a WebWorld and import your new asset to see it in action.
If you are an engineer, open a pull request and help us extend support to new file types or metadata standards. If you are part of another platform, reach out; we would love to test this with other platforms!
We are committed to an open metaverse built on transparent protocols. Through tools such as MML and Atlas, and community driven experiments like our converter, we are making that vision real, one asset at a time.
