A dealer who quoted the currency and a builder who opened Korea's mobile payments era. One team.
AI is starting to work in financial markets.
We're laying the groundwork.
AI already reads, writes and reasons. But working in a financial market takes more than intelligence.
It has to understand the company, know the market, and follow the rules.
An AI that can't see the cash position can't make the call. One that can't see a tradable price can't act. And nobody hands money to an AI without controls in place.
KustodyFi builds those three things as infrastructure.
MOVE structures the company's cash flows into financial context AI can read,
SNAP delivers tradable market prices,
and SEAL blocks any execution outside policy and approval.
On top of that, AI proposes, people decide, and the system proves it. Final approval always belongs to a person.
