The real USD and USDT/RUB rate
This page explains the USD reference rate without presenting it as a bank quote. SAIKYO exposes live market data through /api/rates; the exchange direction, payment method and execution conditions determine the final result.
Current rate
Live value from the public SAIKYO rates API.

USD, USDT and the exchange rate
The Central Bank USD rate and an exchanger’s USDT/RUB rate are different values. The first is published by the Bank of Russia; the second reflects a source and direction conditions. The final order may differ from either number; check the order screen before paying.
How to compare
Compare date, time, base currency and direction. Do not mix a USDT buy rate with a sell rate. If the source is missing or stale, ask support.
Exchange directions
Note
The page is a navigation reference. Fees, limits, network and AML/KYC depend on the order and must not be invented.
Before an order
Label every number with its source and timestamp. The Central Bank USD rate is an official reference, while SAIKYO USDT/RUB belongs to an exchange flow and may reflect a different market, network, payment method and margin. The order screen is more important than a generic chart because it shows the direction, amount, rate and requisites. History is for observing a trend after points accumulate, not for promising a future quote. If widget, API and order values differ, pause and ask support.
Before publishing or paying, record the check date and separate static page facts from runtime API data. The explanatory text describes a process, while /api/rates, /api/reserves and /api/reviews change over time. An FAQ range is not a universal limit for every network, and an aggregate review count is not a substitute for the source reviews. If a parameter is absent from the checked source, the correct action is to ask support, inspect the order and wait for an answer. This avoids confusing an old screenshot, another domain or another direction.
For an independent check, open several sources, but do not turn them into a single guarantee. Terms describe general conditions, the FAQ lists published scenarios and ranges, the backend/API exposes current state, and a monitor provides its own direction snapshot. These layers may update at different times. Record the URL, date, network and amount so support can reproduce the question. Where a legal or financial interpretation is not published, this page keeps a neutral wording instead of guessing.
Before any transfer, verify the correct domain and the network named in the order. A crypto address cannot be corrected after sending, and a wrong network may delay or prevent crediting. Never share SMS codes, passwords, seed phrases or private keys with support. In a dispute, keep the time, order ID, rate screenshot and transaction hash, while removing personal data from public chats. Support may request additional KYC/AML information, but that is never a reason to disclose wallet secrets.
When comparing two orders, keep the conditions equal: the same asset, network, payment method and time. Changing one parameter can change the available rate or limit. Do not transfer a page’s terms to another domain, Telegram bot or partner interface without checking the address. Internal links are navigation aids; execution is determined by the current order form. Ask support about method availability and unusual amounts.
