How each exchange is built
Variational Omni is a decentralized exchange (DEX) on Arbitrum. You trade from a self-custody wallet. It uses request-for-quote: a market maker quotes each trade, and there is no public order book. The price you get is the quote for your size, so there is no book to read for depth.
Coinbase International is a centralized exchange (CEX): you open an account with the company, and the account holds your funds. It matches orders on a central limit order book, where a limit order can rest until it is filled.
Fees and what they mean
Variational Omni's base tier is 0 bp maker and 0 bp taker, per Variational's fee page. Coinbase International's base tier is 2 bp maker and 4 bp taker, per Coinbase International's fee page.
A market order pays the taker fee to open and again to close: 0 bp per round trip on Variational Omni, 8 bp on Coinbase International. A limit order that rests on the book pays the maker fee instead. Coinbase International charges 2 bp for it, and Variational Omni's maker fee is also 0 bp.
Fees are only part of a trade's cost. Slippage, the price you move by eating through the order book, grows with size. The round trip in the cost table above includes it, which the fee alone does not show. Read the table at your own size.

Reading the numbers on this page
Variational Omni publishes open interest as the sum of traders' longs and shorts, against a pool or dealer. Coinbase International publishes one side of open positions. For the same positions Variational Omni's figure reads about twice as large, so the open interest row and chart above are not a like-for-like comparison of size.
Neither exchange has a TVL row or chart. DefiLlama has no figure for Variational Omni, and a centralized exchange such as Coinbase International publishes none. Because Variational Omni quotes each trade, the order-book depth row in the Head to head table has no public book to read for it, so compare cost in the cost table instead.
