FIRO to USDT (ERC-20): questions and answers
How do I swap FIRO to USDT (ERC-20) without KYC?
Enter the FIRO amount on this page, paste your USDT address and send your FIRO to the deposit address shown. AltoSwap has no accounts and asks for no identity documents, and it routes your swap through exchanges rated A for KYC, meaning providers that do not run identity checks. The USDT is paid directly to your wallet.
What is the FIRO to USDT (ERC-20) exchange rate?
The rate moves with the market every few seconds and depends on the amount. The calculator at the top of this page requests live quotes from 20+ exchanges and shows the best current FIRO to USDT rate for the amount you enter.
What are the minimum and maximum for FIRO to USDT (ERC-20)?
The minimum is about 5.26 FIRO and the maximum about 1,642,281 FIRO. Limits vary slightly between exchanges and follow market prices; the form tells you immediately if your amount is outside the range.
How long does a FIRO to USDT (ERC-20) swap take?
Usually 5 to 30 minutes. Most of that is waiting for your FIRO deposit to confirm on Firo, which takes about 10-30 minutes. There is no verification step, so nothing else adds to the wait.
Is swapping FIRO to USDT (ERC-20) anonymous?
AltoSwap does not know who you are (no account, no email, no identity checks) and the default route uses no-KYC exchanges. Your FIRO deposit is private by Firo's design; the USDT payout is a normal public transaction on Ethereum.
Which USDT address should I use?
Your USDT is paid on Ethereum. Use an address that starts with 0x and is 42 characters long. Always use an address in a wallet you control and double-check the first and last characters before sending.
What fees are included in the FIRO to USDT (ERC-20) rate?
Everything. The exchange's spread, the Ethereum network fee for the payout and any service commission are already inside the quoted rate, so the amount shown is what you receive: exactly on a fixed rate, approximately on a floating rate. You only pay your own Firo network fee to send the deposit.
Can I swap USDT (ERC-20) back to FIRO?
Yes. The reverse direction, USDT (ERC-20) to FIRO, works the same way and has its own page and live rate on AltoSwap. Each direction is quoted independently, so the two rates are not exact mirrors of each other.
