How we compare
USDT to USDT across chains. Cost is how much less than 1,000 USDT comes out of a 1,000 USDT swap. Ours is computed live for the pair you picked above; the others quote one flat all-in rate.
Sources and method
Sources: sideshift.ai/api/v2/pair, api.changenow.io/v1/exchange-amount, exolix.com/api/v2/rate, and the /info endpoint of this service. Rates move: ours is recomputed every ten minutes, the other three are re-measured hourly from those same public endpoints. "Not verified" means the provider publishes no keyless figure we could check.
