The Fee You Never Agreed To 👀

Gas is the number you approve before you sign, and it is not the one that decides your fill.

That gets decided in the gap between broadcasting an order and having it settle, where anyone reading the mempool can price against you.

And none of it shows up as a fee anywhere.

Most of the aggregator volume on Solana routes through $JUP , so most of the order flow worth reading crosses a single surface.

That surface is valuable enough that Jupiter spent real engineering on MEV protection and Jito bundles to narrow the window, while the institutional side went the other way entirely and $CC now settles size on domains where a counterparty only receives its own slice of a deal.

Two completely different markets, both paying to close the same exposure.

That is the part I keep coming back to.

Not a rounding error, when a retail router and a network run by Goldman Sachs, BNP Paribas and Nasdaq are both spending money on the same problem.

Arcium works one level below both of them.

A computation splits across a cluster of nodes and each node only holds a fragment of the input, so no operator assembles the whole thing at any point.

So an order book can match on that basis without the venue reading the orders it is matching.

The trade that comes out still settles on Solana as an ordinary public transaction anyone can verify.

But I want to be precise about what is live.

Sealing a computation has run on Mainnet Alpha since February 2, with more than 4,000 nodes and over 30 apps in production.

Sealing a transfer amount is C-SPL, and that has not shipped.

Which means the confidential order book everyone talks about is half built, and the half that exists is the harder half.

My read is, whoever ships confidential matching on Solana first takes the size that has never come onchain, because an order nobody can read is an order nobody can trade ahead of.
