Small tools: work it out before you press confirm
Five small things for checking a number or a decision before it becomes irreversible. All of them run in your browser, none of them upload anything, and none of them need access to your account.
-
Fee comparison table
Enter a trade size and your own rates; get the full maker/taker × discount matrix, and see which cell actually saves the most.
-
Withdrawal network picker
Four questions, then a chain and the reason for it. It gives you nothing until you have confirmed what the receiving end supports — which is the input the whole decision rests on.
-
Payment-block risk self-check
A checklist to run before a P2P trade, putting the habits you have not adopted back in front of you. No score, and no risk percentage.
-
Address format validator
Paste an address and find out which chain it belongs to and whether the format is valid. Tron, Bitcoin Base58 and bech32 / bech32m all get a real checksum computation.
-
Liquidation price estimator
Entry price, leverage and direction in; estimated liquidation price and tolerance out. Mostly useful for seeing how thin high leverage really is.
How to use these
What they have in common: they are for before the decision, not after the accident. Check an address before withdrawing, run the checklist before a P2P order, compute a liquidation price before opening a position. Each takes under a minute, and the errors they catch are the ones that cannot be undone.
Their limits are worth stating too. These tools do arithmetic and format checking. They do not know where the market is going, whether a particular counterparty is honest, or what the platform's rules are at this moment. They can make what you already know precise. They cannot make the judgement for you.
