Justin Sun Hints at TRON-Stellar Alliance After Visiting McCaleb’s Space Firm
Justin Sun met with Stellar founder Jed McCaleb at Vast, McCaleb’s space infrastructure startup.
Sun’s history with Ripple and McCaleb’s legacy in crypto set the stage for renewed partnerships between TRON, Stellar, and Ripple communities.
After Vast, Sun visited SpaceX, suggesting bold ambitions linking crypto projects with the space sector.
This crossover has got Twitter buzzing! TRON founder Justin Sun recently paid a visit to Jed McCaleb, the low-key legend behind Stellar and Ripple. Oh, and here’s where it gets interesting. The meeting took place at Vast, McCaleb’s space infrastructure startup.
Sun’s takeaway? “This is just the beginning.” And if you know anything about how he moves, you know he means it.
From Peer-to-Peer to Space Stations
Sun took to X to thank McCaleb for the meeting.
“From eDonkey to Mt. Gox, Ripple, and Stellar, your journey has been a continuous source of inspiration for me. I hope we can have more collaboration in the space sector in the future”
McCaleb’s resume speaks for itself. He built eDonkey in the early 2000s, co-founded Mt. Gox, helped launch Ripple and the XRP Ledger, and later created Stellar. Now he’s moved beyond blockchain to focus on space infrastructure with Vast, where he’s building next-gen space stations.
A Long-Running Thread Between TRON and Ripple
Before launching TRON, Sun was Ripple’s first hire in China – a role that gave him a front-row seat to early crypto development. That early connection has resurfaced from time to time, with even Ripple CTO David Schwartz acknowledging Sun’s past contributions.
There’s a history here. And maybe, the beginnings of a bigger alignment.
One More Stop: SpaceX
After meeting McCaleb at Vast, Sun made another interesting visit – this time to SpaceX. He shared a playful photo in front of a Falcon 9 rocket, hinting at a possible joint mission with Elon Musk. It fits the moment, doesn’t it?
Why It Matters
Sun has always had a flair for dramatic moves but this one feels different. With McCaleb now building for orbit and Sun publicly pushing for “collaboration in the space sector,” it’s clear these conversations are headed for massive impact. We’re excited!
