Hush doesn’t take a cut. The exact amount shows up on the review screen before you confirm.
How long things take
- First open
- Your browser downloads and checks RAILGUN’s history once. About a minute. After that it’s quick.
- New deposits
- Usually a few minutes before you can spend them, while the clean-funds check runs.
- Sending
- Your browser builds a zero-knowledge proof first: roughly 10 to 30 seconds on a laptop.
Almost ready.
