A swap costs the rate plus the cost of sending the coins. Here is our second number, in full.
The charge for moving your coins to your address does not shrink with the size of your order, so on a small swap it can be most of what you lose — and it is the number comparison tables leave out. Ours is below for every one of the 31 routes we pay out on, across 15 chains. It is declared on the quote before you commit, and it is the same figure our payout code charges.

Why the numbers are so different from each other
They are costs, and the costs genuinely differ. Tron is the busiest rail for USDT and we staked TRX for the energy those transfers burn, so the charge is cost recovery at 0.15 USDT. Solana is cheap to transact and expensive to arrive on for the first time: paying a token to a wallet that has never held it makes us open that wallet’s token account, about 0.00203928 SOL, every time. Bitcoin rides the mempool. Averaging those into one tidy figure would be wrong on every chain at once.
The rule underneath the table. No fixed cost of paying someone out may exceed what we earn on the smallest swap we accept on that route. A charge set below its own cost is not generosity, it is a hole: whoever finds it can repeat it until the wallet is empty, and they never have to break anything to do it. We found one — Solana token payouts once charged 0.000005 against a real cost of about $0.21 — and one automated actor ran 36 swaps through it before it was closed. So a route we cannot cover at a sensible price is one we withdraw rather than quietly absorb.
Frequently asked
Does Cambio charge a fee to send my coins?
Yes, and it is on this page in full — 31 payout routes with the exact amount for each. It is declared on the quote before you commit, never deducted silently afterwards, and it is the same number our payout code charges: the two are held together by a test rather than by good intentions.
Why does it cost more on some chains than others?
Because it is a cost, not a margin. Sending USDT on Tron uses energy we staked for, so it is 0.15 USDT. Sending a token on Solana to a wallet that has never held that token makes us pay to open the recipient's token account — about 0.00203928 SOL every time — so Solana token payouts carry more. Bitcoin moves with the mempool. We publish what each one costs rather than averaging them into a single number that would be wrong on both.
Is this the only cost of a swap?
No, and that is the point of listing it separately. A swap costs the commission inside the rate plus the cost of sending the coins. The second one does not shrink with the size of your order, so on a small swap it can be most of what you lose — which is exactly why comparing headline rates alone is misleading. Compare the amount that actually arrives.
What about the other exchanges Cambio compares?
Each sets its own payout charge on its own terms, and this page prints no figure under anyone else’s name. What Cambio does is rank the panel on the amount that arrives after every fee it can read, rather than on the headline rate — and where an exchange publishes no such figure at all, its page here says so.
Every exchange on the panel
Cambio asks each of these for a live price on every swap and ranks them on the amount that arrives after every fee it can read. Each page says what that exchange publishes, what it is good at, and what we would want to know before using it.
