MERIDIAN WORLD MODEL

Real fills, verified. The market, in the open.

A live model of the stock-token market on Robinhood Chain, rebuilt from every confirmed fill.

FILL INTAKE

Every Uniswap v3 swap in a stock-token pool is read the block it lands.

VERIFIABLE TRAJECTORY

Each fill links to its transaction on Blockscout. Open any one of them.

EVIDENCE LAYER

Fills become labels: price paid against the consensus mid, size, side, venue.

NO-CUSTODY ROUTING

Quotes run on QuoterV2. Your wallet signs one transaction to the Uniswap router — Meridian keeps nothing.

MARKET WORLD MODEL

One live state of the stock tokens: consensus price, depth, and best route.

Every fill adds up. The proof stays open.

Real fills only

The market teaches through consequence. Every number on Meridian is a Swap event or a pool read on Robinhood Chain. Nothing is simulated and nothing is estimated from outside the chain.

Open proof

Check the model against the chain. Each fill carries its block and a link to its transaction. The public API returns the same data this page draws.

No custody

Your keys, your route, your fill. The Swap Gateway quotes every candidate pool and your wallet signs one transaction. Meridian holds no funds and makes no market.

Execution is one transaction from your wallet to the Uniswap v3 router. Meridian is not a party to it and keeps no balance.
Every fill your trade makes lands in the model above, with its transaction linked.
