Free tools for the daily work of an exchange office
The same tools we use inside the Nexto software — the free version, for everyone.
🏦 SHEBA (Iranian IBAN) Validator
Check an IBAN right here; the bank name and account number are extracted too — instant, no sign-up.
📈 FX Rate Archive Since 2008
Daily prices of the US dollar, euro, pound, Turkish lira, UAE dirham, Iraqi dinar, yuan and gold from 2008 to today — with the average, low and high of every year and month.
✍️ Amount to Words
Type a number and get it written out in words — like the forms inside Nexto.
🛡️ USDT transaction tracer and fake token check
Paste a transaction hash or an address — we read the sender, the recipient, the amount and the currency straight from the blockchain and warn you if the token is fake.
🔜 Coming next
Sayadi cheque lookup, card-to-IBAN conversion and a receipt OCR demo are on the way.
Why are these tools free?
Each of these tools is a piece of Nexto exchange software that works inside its forms every day: IBAN validation in deposit requests, amount in words in the trade form, the rate archive in revaluation and transaction tracing in crypto entries. We put their open versions here so you can use them without signing up.
All tools either run in your browser or only read public data; nothing is stored and none of them needs an account.
Frequently asked questions
Is there any limit on using the tools?
No; all tools are free and need no sign-up. Only the crypto transaction tracer has a per-minute request cap to prevent abuse.
Is the data I enter stored?
No. IBAN validation and amount-to-words run entirely in your browser, and the rate archive and transaction tracer only read public data.
Are these tools also inside Nexto?
Yes; the same engines run inside Nexto exchange software forms, connected there to customers, entries and accounts.
These tools are just one corner of Nexto — the complete exchange office management software. See the platform
