Gravity Protocol

Trading through an intermediary means someone can see your order before it settles and take a slice of it. Gravity is building a decentralised exchange on Cardano with deterministic swaps and protection against that reordering, so the price a trader is shown is the price they get.

Every trade placed through an intermediary is an opportunity for someone else. In decentralised markets the mechanism is public: transactions sit visible before they settle, and whoever controls the ordering can insert themselves. The result is a spread that nobody quotes and everybody pays, and it applies to careful institutions exactly as it applies to retail.

Gravity's approach is to remove the discretion rather than to police it. Deterministic swaps mean the outcome is fixed by the protocol rather than by whoever assembles the block, which is a design decision instead of a policy. The whitelist and the unprompted testnet use are what a pre-launch protocol has instead of revenue: evidence that people want the thing enough to try it before it pays them to.
