Measured. Every trade on this page is a real swap in the vej pool, with its real size, price and wallet. Price, market value, pool depth and holder count are read live, once a second. Every set of three probabilities is a real answer from Jev, asked once, at the moment of the trade, and stored with the exact facts it was given and the time it took to answer. The model's speed and cost shown on the model page are measured here, not quoted.

Defined here. The question, and the three routes it can choose between. The facts we chose to show the model. The weight formula. Balances and the share a wallet has sold are built from the trades this site has seen since it began watching, so a wallet that received tokens by transfer will look lighter than it is. The amounts on this page are what each route and each wallet is owed by the rule. Moving the money is a separate step, and the earned column only counts as paid once a transfer is recorded.
