How to read confirmations
Once an on-chain transfer goes out, it isn't settled until several blocks have bundled it in and "stamped" it. The more confirmations required, or the slower the chain produces blocks, the longer you wait. Bitcoin produces a block roughly every ten minutes and tends to require more confirmations, so a Bitcoin deposit is usually on the slower end of the major coins. Ethereum is about twelve seconds per slot, while Tron and Solana produce blocks very fast, so those feel a lot quicker. But how many confirmations it actually takes to arrive is set by Binance based on risk, it changes, so don't treat it as a fixed number.
To understand why some chains are fast and others slow, and how to check when one is stuck, read how long deposits take. If you've genuinely waited too long and suspect something's wrong, walk through the deposit troubleshooter step by step.
It doesn't go online, doesn't check the live confirmation progress of your particular deposit, and doesn't report an exact number of minutes. The table shows the rough order of magnitude for each network. To see "how many confirmations are left," open your Binance deposit history and the matching block explorer for the live count.
