off-chain matching + on-chain settlement con ZK proofs (anti front-running), Retail Price Improvement (RPI) orders

A few months ago I watched a trade get worse the exact second I hit confirm — the price I saw wasn't the price I got, and the gap was too clean to be coincidence.

I started calling that gap the order-book leak: the small, repeated tax that happens when someone else sees your order before it settles and moves first. It rarely shows up as a single dramatic loss. It shows up as a hundred small ones you stop noticing because they feel like "just how trading works."

@grvt_io 's architecture separates order matching from settlement and verifies every trade with zero-knowledge proofs on Ethereum, which is the specific design meant to close that gap — on top of retail price improvement orders that check for a better execution price automatically before a trade fills.

Whether that fully closes the leak in practice, versus just making it harder to see, is something I'd want more independent execution data on before calling it solved. But the last time I watched a fill happen live, the price didn't move against me first.
