The Price of Arrival

Every quote our engine produces describes a journey: this asset, this amount, from here, to there, arriving as that. For a long time the pricing inside that journey had a quiet fiction in it. The leg you give was valued at face — the spot price of the asset, as if it were already where it needed to be. The costs of converting it and moving it were real, but they lived in a different part of the calculation, applied afterward, inconsistently, and sometimes not at all.

Face value is a number that assumes teleportation. An asset sitting on one network is not worth its sticker price on another; it is worth whatever remains after you swap it into something the destination understands and pay to carry it across. A route that ignores that is quoting a price nobody can actually get.

Pricing the trip, not the ticket

This release rebuilds the book around realizable value: what an asset is worth at the location where it will be spent, not where it currently sits.

Concretely, that meant teaching the engine to ask the venues themselves. Solana legs are now repriced through live aggregator quotes rather than a static price table. Tron and HyperEVM assets carry proper metadata so their decimals and identities resolve correctly instead of being guessed. Each rail carries a transport cost — the honest expense of moving value across that boundary — and the give leg is priced net of it. If a quote or a metadata lookup fails, the route fails closed: no price is better than a wrong one.

The difference sounds small until you run it. A route that "looks" profitable at face value can be underwater once the give leg is honestly repriced — and routes that looked marginal can turn out to be the best available. The book stopped flattering itself.

Capital is a cost, not a assumption

The second change is about how fills are funded. Not every route can settle atomically — sometimes the cheapest liquidity sits behind a borrow that repays later, across a settlement window. The old model treated funding as free infrastructure. The new one makes it explicit:

• Atomic fills draw on atomic liquidity — the capital cost is effectively zero because the funding exists only inside the transaction.
• Deferred fills borrow over a repay window — the capital is real, it has a duration, and it has a price.

Every route record now carries which kind of fill it is and what the capital costs. A deferred route that wins on price but loses on capital cost should lose — and now it can, because the cost is in the margin calculation instead of hidden in a footnote.

The book that notices its own crossings

One quieter feature fell out of the same rebuild: crossings. When two independent orders in the book want opposite things — one selling what the other is buying, with enough overlap to matter — they can satisfy each other directly. The index now detects those pairs and surfaces them, which matters for a book whose whole premise is that fragmented liquidity is best consumed by matching, not by paying spread to an intermediary that doesn't need to exist.

What this does not claim

Realizable value is only as real as the quotes behind it. A Solana repricing is an indicative aggregator quote until it executes; transport costs are estimates until the message lands. The book fails closed on missing data, but "fail closed" still means "no answer," and sometimes the honest answer is that we don't know yet. Coverage is also uneven by design — deep EVM liquidity, thinner long-tail rails — and the intent feed we opened alongside this work publishes coverage counts so consumers can see exactly where the book is strong and where it's guessing.

The through-line is the same one that runs through everything we ship: a number is only worth quoting if it's the number you can actually get. Face value was easy to compute and wrong to trust. The price of arrival is harder to compute — and it's the only one that's real.
