What does HashDude do?
When you swap tokens or send multiple transactions, normal apps broadcast them publicly. Bad actors can see that and attack you.
Normal way
Your trade is visible to everyone first. Bots can jump ahead of you.
HashDude way
Your trade goes through our private relay. It lands hidden and all at once.
Safe
Nobody can sneak in front of you
We call this “MEV protection.” Here’s what that means in normal words:
Your keys stay yours
We never ask for your password or private key. You sign on your own device. We only deliver.
All or nothing
If one part of your bundle fails, the whole thing fails. No half-done swaps.
Fast
Everything lands in one block
Multiple transactions? They all go in together — not spread across different blocks.
-
1
We wait for the right moment
HashDude syncs to the next block on Robinhood Chain.
-
2
We send everything at once
All your transactions fire together in one burst.
-
3
We double-check
Every transaction must be in the same block — or we reject the bundle.
