How an OTC rate is built
What goes into the number on a held quote.
5 November 2026
A large order on a public book eats through the resting offers and fills at a worse price with every step. Selling 500 ETH that way can cost far more than the fee on the screen suggests.
Where our number comes from
We start from the live bid if you are selling and the live ask if you are buying. Then we add a commission, which depends on how you settle. Bank transfer costs less than cash because cash has to be counted, moved and insured.
Why the quote expires
ETH can move half a percent in a minute. A 60-second window lets us stand behind one price for the whole ticket without padding it to cover a longer wait.
