About the Depth Ledger Desk

What the desk covers

The subject is liquidity rather than price. That means pool reserves and what they imply, depth at stated distances from mid, the accounting behind LP positions, the arithmetic of the gap against holding, and the movement of capital between venues on Solana.

The site is organised into two sections and one reference. Pools covers standing state: the invariant, the ladder, the transaction that creates or destroys a position, and the comparison against holding. Flows covers movement: where liquidity comes from, why reserves fall, and how to keep a series that records the change honestly. The glossary carries the vocabulary the entries lean on.

Anything that requires knowing what a price will do next is out of scope. So is anything requiring knowledge of who is behind a position, because a pool account records amounts, instructions and signers, and none of those is a person or a motive.

Who writes these entries

Entries are written and reviewed by The Depth Ledger Desk, which is the editorial function of this publication rather than a named individual. There is no author photograph, no invented biography and no claimed credential attached to any entry on this site.

That choice is deliberate. A byline on this subject is frequently used to import authority that the writing has not earned, and inventing a persona to do it is a fabrication whatever else it accomplishes. The entries stand on whether the mechanics they describe are correct, and every one of them can be checked against published protocol behaviour by anyone who wants to.

Where the material comes from

Three kinds of material appear here, and they are kept distinct in the text.

The first is protocol mechanics: how a constant-product pool computes a quote, what an add or remove instruction does, how concentrated ranges quote and stop quoting. This is public, documented and checkable, and it is stated as fact because it is.

The second is derived arithmetic: depth ladders, the gap against holding, decomposition of a reserve change into trading and liquidity components. These are consequences of the first category and are presented with the derivation visible rather than as results to be taken on trust.

The third is interpretation: what a pattern in the data might mean. This is always marked as interpretation, always accompanied by the alternative explanations that remain live, and never converted into a confident claim about anyone's intent.

How numbers are handled

Worked examples are the only honest way to teach pool arithmetic, so this site uses them throughout. Every one carries a visible stamp saying the figures are illustrative, and states that it describes no real pool, position or pair.

No yields appear anywhere on this site. A fee rate is a protocol parameter and can be stated; what any provider earned from it depends on flow through their specific position over a specific period, which is not something this desk knows. Publishing an expected return would require either a measurement that has not been made or a number that has been invented.

No frequencies appear either. Statements of the form that some pattern occurs a certain proportion of the time require a defined population and unbiased sampling. Where this desk lacks both, the word printed is unknown rather than an estimate that would describe the selection process rather than the market.

The one place round numbers appear without a stamp is where they are properties of a formula rather than observations, such as the table of divergence values derived from the constant-product expression. Those are arithmetic, and the derivation is given so a reader can reproduce them.

What the desk refuses to publish

• Any claim that a named token, team, wallet or venue acted in bad faith. Intent is not recorded on chain and no amount of data supplies it.
• Any price expectation, target, entry or exit. Reserve data has no path to one and this desk publishes none.
• Any yield, expected return or performance figure for a liquidity position.
• Any fabricated statistic, review count, rating, testimonial or invented person.
• Any frequency claim that has not been measured against a defined population.
• Any attribution of a wallet to a person or organisation.

The position this desk takes on risk

Supplying liquidity is a position with real downside. As the price ratio between two assets moves, a pool rebalances a provider claim towards whichever asset performed worse, and the resulting basket can be worth less than the two assets would have been if simply held. Fee income works against that gap and is not guaranteed to cover it.

On top of that, a liquidity position carries whatever risk attaches to the two assets themselves and whatever risk attaches to the program holding the funds. Any one of those can dominate the others in a given period.

None of that is a reason to avoid the subject, and none of it is a recommendation either way. This desk describes how the machinery behaves. What anyone should do with their own money is a decision it has no basis for making on their behalf, and nothing on this site is financial advice.

Corrections

Entries are corrected rather than quietly removed. When a mechanic is described incorrectly, the entry is fixed and the fix is a normal edit; when a conclusion turns out to have been unsupported, the conclusion is changed and the reasoning that replaced it is visible in the text.

The most useful correction anyone can send is a mechanical one: a protocol behaves differently from how an entry describes it, an arithmetic step is wrong, or a worked example does not reproduce. Those are checkable and they get fixed quickly. The contact page explains what to include.

Commercial links

Some pages on this site link to a commercial volume automation platform. Those links are marked by their placement and by the sentence introducing them, which always states that the destination is a commercial product rather than a research page.

They exist because the flow side of a market is genuinely part of this subject: depth decides what trading costs, and sustained trading decides who is willing to supply depth. A reader studying reserves eventually wants to see how routed activity is configured, and pretending otherwise would make the entries less useful, not more honest.

Those links do not change what is written here. No entry recommends any product, no entry claims a result for one, and the risk statements on this site apply exactly as they would if the links did not exist.
