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.

THIS CORRIDOR, IN NUMBERS
USDC on Ethereum → USDT on Ethereum
What USDC → USDT actually costs
- You send 100 USDC on Ethereum.
- You receive 98.8299 USDT.
- The smallest swap this corridor accepts is 109.978 USDC.
Why this pair behaves the way it does
Ethereum confirms in seconds per block, and 4 confirmations is enough to make a reorganisation impractical without leaving your USDC sitting there.
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 on Ethereum and USDT on Ethereum
USDC and USDT both track the dollar, but they are separate tokens on separate chains — USDC issued on Ethereum, USDT issued on Ethereum.
Worth checking before you send: on Ethereum the token is 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48, and the USDT you receive on Ethereum is 0xdAC17F958D2ee523a2206206994597C13D831ec7.
Ethereum needs 4 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 Ethereum, receive USDT on Ethereum, no account.
How long USDC on Ethereum takes to clear
Cambio waits 4 confirmations on Ethereum, then sends the payout immediately. End to end this corridor typically takes ~5 min.
