Five tools, five different kinds of question. None of them makes a network request, none stores anything, and none can give you live data, which is a limitation we would rather state than work around badly.
Which one answers your question
| Your question | Tool | What it is |
|---|---|---|
| Can I even register from here? | Eligibility self-check | A lookup against a compiled table |
| What am I really paying per trade? | Effective fee calculator | Arithmetic on numbers you supply |
| Is this address safe to send to? | Address format checker | A validator, honest about its limits |
| What do I need to photograph? | Document checklist | A checklist builder |
| What does holding this position cost? | Funding rate converter | A unit converter |
The tools
- Eligibility self-check
Pick a region and see the platform's availability status, what the peer-to-peer book looked like when we queried it, and the specific limitations worth knowing. - Effective fee calculator
Stack the discount layers the way the exchange stacks them, fold in the purchase premium, and see how far the addition method is off. - Deposit address format checker
Full checksum verification where the format supports it, character and length checks where it does not, and a clear statement of which you got. - Verification document checklist
Three quick choices produce the list for your document, your device and whether proof of address is needed yet. - Funding rate converter
Turns a per-interval rate into a daily cost, a period total and an annualised figure, so it can be compared against everything else.
What none of them do
No live data. No prices, no current fee rates, no real-time availability. Every tool here works entirely in your browser, and nothing you enter is sent anywhere. Try one with your internet switched off: it still works, which is better evidence than our word for it.
That is a deliberate trade rather than a missing feature. A tool that promised live rates would have to fetch them from somewhere, and when that source went stale or broke, the page would quietly display something wrong. Given the choice between a tool that occasionally lies and a tool that asks you to type two numbers, we took the second one.
It is also why the honesty statement on each tool matches what the code actually does. A page here claiming real-time data would be contradicting its own privacy page, and that would be a bug worth reporting.
Why these five and not a wall of calculators
Every affiliate site in this subject seems to have a fee calculator and a liquidation calculator, and little else. Five near-identical calculators is not a toolkit; it is one tool repeated.
These five are deliberately different in kind — a lookup, a calculator, a validator, a checklist builder and a converter — because the questions people arrive with are different in kind. The eligibility checker exists because the "supported countries" articles we read while researching this site contradicted each other badly. The address checker exists because the alternatives claim checksum verification and mostly do not perform it.
Where each one fits
The eligibility check and the document checklist belong before you register — see getting started. The address checker belongs immediately before any transfer, alongside deposits and withdrawals. The fee calculator and the funding converter belong with fees and costs, which explains what the numbers you feed them actually mean.
