It doesn't look like they're partnering with any big crypto projects like ONDO but still, this is looking like a good step forward.
As far as i know ICE is being developed together by NYSE, Citi Bank and BNY. They're all have strong relationship with Canton Network caused by they were also the main investors of Canton Network.
So i expect them to use Canton. They will not use other RWA platform like ONDO or etc. I personally have made some investment on Canton for long-term.
