What AWS has been for Web2, @SuiNetwork💧 is for Web3 — no one knows that better than @EmanAbio.

Honored to be working alongside the talent building the future of the internet and bringing the next billion users to Web3.

.@SuiNetwork is the only blockchain that can handle the scale tomorrow's developers need to bring Web3 to one billion users.

That's why @millcity_3 is in this for the long haul. The companies already building on it are doing incredible work, and there's much more that's coming.

[stephen mackintosh @S_A_Mackintosh]

As I told @EmanAbio: If you think you missed out on @SuiNetwork, think again.

It's only just getting started — and so are we.

Chatted with @zGuz on @coinage_media this morning about how crypto has a trillion-dollar, billion-user future–which only @SuiNetwork makes possible.

The #Sui ecosystem offers things most other blockchains don’t. @millcity_3 is committed to it for the long-term, as it’s undeniable that it will be at the center of Web3’s growth. $MCVT

[stephen mackintosh @S_A_Mackintosh]

Thanks for having me this morning, @zGuz and @coinage_media.

The demand for crypto is growing, and $MCVT is the only way to access $SUI in an institutional-grade wrapper, managed by an active team with a deep belief in the blockchain’s future.

The future of Web3 lies in @SuiNetwork, and we’re excited to be part of that.
