What you gain from this page is the ability to read a swap receipt the way the contract reads it. A receipt is the summary shown after your swap confirms, and every line on it corresponds to something the Router either measured or refused to accept. Six lines matter.

How to read your swap receipt: delivered, quoted, floor, route, link, stamp
How do you read your swap receipt?
The six things a swap receipt tells you — what you were quoted, what arrived, the floor you signed, the route your tokens took, the transaction link that proves it, and the stamp that records when the site last read isSolvent() from the staking engine.

English — The six things a swap receipt tells you — what you were quoted, what arrived, the floor you signed, the route your tokens took, the transaction link that proves it, and the stamp that says the Router kept nothing — and what a surplus and a shortfall each mean.
Português — As seis coisas que um recibo de swap lhe diz — o que lhe foi cotado, o que chegou, o piso que assinou, a rota que os seus tokens seguiram, o link da transacção que o prova, e o carimbo que diz que o Router não ficou com nada — e o que significam um excedente e um défice.
Español — Las seis cosas que te dice un recibo de swap — qué te cotizaron, qué llegó, el suelo que firmaste, la ruta que tomaron tus tokens, el enlace de la transacción que lo prueba, y el sello que dice que el Router no se quedó con nada — y qué significan un excedente y un déficit.
Français — Les six choses qu’un reçu de swap vous dit — ce qui vous a été coté, ce qui est arrivé, le plancher que vous avez signé, la route qu’ont prise vos tokens, le lien de transaction qui le prouve, et le tampon qui dit que le Router n’a rien gardé — et ce que signifient un excédent et un déficit.
Deutsch — Die sechs Dinge, die eine Swap-Quittung Ihnen sagt — was Ihnen angeboten wurde, was ankam, die Untergrenze, die Sie unterschrieben haben, die Route, die Ihre Token genommen haben, der Transaktionslink, der es beweist, und der Stempel, der sagt, dass der Router nichts behalten hat — und was ein Überschuss und was ein Fehlbetrag jeweils bedeuten.
Русский — Шесть вещей, о которых говорит чек свопа: что вам котировали, что пришло, пол, который вы подписали, маршрут, которым прошли ваши токены, ссылка на транзакцию, которая это доказывает, и штамп, говорящий, что Router не оставил себе ничего — и что означают излишек и недостача.
Türkçe — Bir takas makbuzunun size söylediği altı şey — size verilen teklif, gelen miktar, imzaladığınız taban, tokenlarınızın izlediği rota, bunu kanıtlayan işlem bağlantısı ve Router’ın hiçbir şey alıkoymadığını söyleyen damga — ve bir fazlanın ve bir eksiğin ayrı ayrı ne anlama geldiği.
العربية — الأشياء الستة التي يخبرك بها إيصال المبادلة — ما الذي سُعِّر لك، وما الذي وصل، والحد الأدنى الذي وقّعت عليه، والمسار الذي سلكته عملاتك، ورابط المعاملة الذي يثبت ذلك، والختم الذي يقول إن Router لم يحتفظ بشيء — وماذا يعني الفائض وماذا يعني النقص.
हिन्दी — एक स्वैप रसीद आपको जो छह बातें बताती है — आपको क्या कोट किया गया, क्या आया, आपने कौन-सी न्यूनतम सीमा पर हस्ताक्षर किए, आपके टोकन किस रूट से गए, वह ट्रांज़ैक्शन लिंक जो इसे सिद्ध करता है, और वह मुहर जो कहती है कि Router ने कुछ नहीं रखा — और अधिशेष तथा कमी का क्या-क्या अर्थ है।
日本語 — スワップの領収書があなたに伝える六つのこと — 提示された見積もり、実際に届いた量、あなたが署名した下限、トークンが通ったルート、それを証明するトランザクションのリンク、そして Router が何も取っていないと告げる刻印 — そして余剰と不足がそれぞれ何を意味するか。
中文 — 一张兑换收据会告诉你的六件事 — 你拿到的报价、实际到账的数额、你签下的下限、你的代币走过的路线、能够证明这一切的交易链接,以及表明 Router 分文未留的印记 — 以及盈余和缺口各自意味着什么。
한국어 — 스왑 영수증이 알려주는 여섯 가지 — 제시받은 견적, 실제로 도착한 양, 서명한 하한, 토큰이 지나간 경로, 그것을 증명하는 트랜잭션 링크, 그리고 Router가 아무것도 남기지 않았음을 말하는 도장 — 그리고 초과분과 부족분이 각각 무엇을 뜻하는지.
Bahasa Indonesia — Enam hal yang diberitahukan sebuah struk swap — berapa yang dikuotasikan kepada Anda, berapa yang tiba, batas bawah yang Anda tanda tangani, rute yang ditempuh token Anda, tautan transaksi yang membuktikannya, dan cap yang menyatakan Router tidak menyimpan apa pun — serta apa arti surplus dan apa arti kekurangan.
বাংলা — একটি সোয়াপ রসিদ আপনাকে যে ছয়টি বিষয় জানায় — আপনাকে কত কোট করা হয়েছিল, কত এসেছে, আপনি কোন নিম্নসীমায় সই করেছিলেন, আপনার টোকেন কোন রুটে গেছে, যে ট্রানজ্যাকশন লিংক তা প্রমাণ করে, এবং যে সিলমোহর বলে Router কিছুই রাখেনি — এবং উদ্বৃত্ত ও ঘাটতির আলাদা আলাদা অর্থ।
Filipino — Ang anim na bagay na sinasabi sa iyo ng isang resibo ng swap — kung ano ang ikinuwenta sa iyo, kung ano ang dumating, ang sahig na iyong nilagdaan, ang rutang tinahak ng iyong mga token, ang link ng transaksyong nagpapatunay nito, at ang tatak na nagsasabing walang itinago ang Router — at kung ano ang ibig sabihin ng sobra at ng kulang.
Quoted, delivered, floor
The quoted amount, also called the predicted or attested output, is what the preview computed for your trade at the moment you asked. The delivered amount is what actually landed in your wallet, measured as the change in your balance, not as the number anyone typed. The floor is the minimum the Router would have accepted: it was attested by the same preview, and if the delivery had landed below it the contract would have refused the trade instead of filling it worse.
The relationship between the three is the whole receipt. Delivered is at or above the floor on every settled swap — that is asserted on every one of the 240 samples of the quote-ageing study, not hoped. Delivered can sit above or below the quote, and the two cases have names.
- A surplus is delivery above the quote. The world moved in your favour between quote and fill. Surplus above the attested quote is fee-exempt — the Surplus Rule — so it is yours in full.
- A shortfall is delivery below the quote but at or above the floor. The world moved against you by less than the floor allowed. You received less than predicted and never less than you signed for.
- A refusal is what happens instead of a shortfall that would breach the floor. There is no receipt for a fill below the floor, because no such fill exists.
A worked reading
The receipt expresses delivered against quoted in basis points, where 10,000 bps is exactly the quote. On a fork of Base, 1,000 USDC quoted into WETH and executed 10 seconds later with nothing else moving delivered 10,000 bps — precisely the prediction. The same quote with 1,000,000 USDC traded ahead of it through the same route delivered 9,974 bps: 99.74 % of the quote, a shortfall of about a quarter of a percent, inside the floor. A million dollars ahead of a thousand cost the thousand a quarter of a percent.
| what happened between quote and fill | delivered / quoted | reading |
|---|---|---|
| nothing moved; executed 0, 3, 6 or 10 s later | 10,000 bps | exactly the quote, four times out of four |
| 10,000 USDC traded ahead | 9,999 bps | shortfall, inside the floor |
| 1,000,000 USDC traded ahead | 9,974 bps | shortfall of about 0.26 %, inside the floor |
| 5,000,000 USDC traded ahead | 10,000 bps | exactly the quote — the big trade used pools your route did not touch |

The route line
The route line names the hops your tokens took — each hop is one token becoming another — and the legs inside a hop, which are the pools that hop was split across. Two hops through a bridge coin such as WETH or USDC is common for a pair no single pool serves deeply. The route line is also where the protocol fee attaches: once, at the first hop whose input is a bridge coin, or once per hop on a route no bridge coin ever enters.
The transaction link and the stamp
The transaction link opens your swap on a block explorer. It is the receipt behind the receipt: the balance changes there are the ones the delivered line was computed from, and anyone can open it without an account. If the two ever disagreed, the explorer would be right.
The stamp is the time at which the site last read isSolvent() from the staking engine on Base — a protocol-level check that refreshes every five minutes, not a statement about your swap. The property that your swap left nothing on the Router is enforced by the contract and checked by the invariant suite; it is not printed on the receipt. That is a property the test suite asserts after every settlement — on every row of both covering arrays and after each of 2,000 fee-fuzz settlements — and it is what makes a shortfall a shortfall rather than a leak: what did not reach you did not stay in the Router either. It went to the pools, as their fee, or to the treasuries, as the protocol fee, and both are measured.
