ChangeNOW delivers the most here — 0.04% more than Cambio, but it has not stated its network fee, so that figure is a ceiling rather than a promise. Cambio is 0.04% behind on paper and is one of the few whose number we can confirm.

Network fee — a stated amount is what the exchange returned, and the figure shown is after it. “included” means the exchange’s own price already contains its network fee, not itemised. “not stated” means its API returned no fee, so that amount is a ceiling rather than a promise.
Every row is what that exchange would pay for this exact size, quoted live from its own API at the time shown and ranked by what lands in your wallet. The bar is each row’s all-in cost against the market rate at that moment, drawn to one scale — ours included.
Cambio was behind the best rate at this check — and we show it anyway. Every quote is compared live, and the number on the card is the number that settles.
Arbitrum produces blocks several times a second, so the 20 confirmations Cambio waits for on your USDC pass almost immediately and the USDT payout is what you are actually waiting on.
USDT on Ethereum is a token, so sending it also needs Ethereum's own coin for gas. Cambio funds that separately, which is why the USDT side is capped by what the wallet holds rather than by a policy number.
Floor on Ethereum: 0.455%. Below that the corridor stops covering settlement.
USDT on Ethereum carries 6 decimals, so every amount on this page is quoted to that precision and no further.
USDC and USDT both track the dollar, but they are separate tokens on separate chains — USDC issued on Arbitrum, USDT issued on Ethereum.
Worth checking before you send: on Arbitrum the token is 0xaf88d065e77c8cC2239327C5EDb3A432268e5831, and the USDT you receive on Ethereum is 0xdAC17F958D2ee523a2206206994597C13D831ec7.
Arbitrum needs 20 confirmations before Cambio releases your USDT; that wait, not the Ethereum payout, is what you spend time on.
People move a dollar token between chains to reach something only one side has: a protocol, an exchange deposit, or a cheaper onward transfer. Cambio does it as a swap — send USDC on Arbitrum, receive USDT on Ethereum, no account.
Cambio waits 20 confirmations on Arbitrum, then sends the payout immediately. End to end this corridor typically takes ~5 min.

Two different assets, two different on-chain stories. Here’s the minimum you should know before you send anything.
USDC on Arbitrum is issuer-native USDC (not a bridged wrapper). The network confirms in seconds, with L2 fees — a fraction of Ethereum L1 gas — and Circle mints it directly on Arbitrum rather than bridging it over.
USDT on Ethereum is the most widely accepted USDT there is. The network confirms in well under a minute, with gas is the price of L1 — it rises when the chain is busy — and acceptance is maximal, with L1 gas applying whenever you move it.

No. Your USDC goes to a Cambio deposit address on Arbitrum as an ordinary transfer, and you receive USDT on Ethereum as an ordinary Ethereum transaction. No bridge contract, no wrapped assets, no cross-chain messages.
The deposit side on Arbitrum confirms in seconds; the payout on Ethereum confirms in well under a minute. The status card tracks every stage live — detection, confirmation, payout — so you are never guessing which side you are waiting on.
No account or sign-up is needed. Every swap is screened against sanctions and on-chain risk lists before a deposit address is issued; in line with applicable law and our risk-based AML policy, identity verification may be requested where screening flags elevated risk.
There is no fixed per-swap cap. The most you can send on this pair is shown in the table above and recalculated on every quote, so it always reflects what we can settle right now.
Yes — on the exchange’s deposit screen pick USDT and make sure the network is Ethereum (ERC20), then paste that deposit address into the Cambio composer as your destination. If the network on the exchange side doesn’t match, don’t send — ask the AI and it will walk you through it.
Every quote ships with a live comparison against the biggest instant exchanges — including when we lose — and the number on the card is the number that settles. Pricing is chain-aware, the route has no bridge exposure, and screening happens before your deposit, never after.
All from the 62,231 active launch-scope pairs. Each one has its own page with live rates, competitor comparison, and chain-specific notes.
