Short answers. Nothing here depends on the amount you're moving.
Does the network I pick change the usdt to xmr rate?
No. USDT is the same asset whichever chain it sits on, so the price is identical across TRC-20, ERC-20 and Solana. The chain changes which deposit address you're given and what the chain itself charges you to send. The rate stays put.
Which USDT network should I use?
Whichever one already holds your balance. Moving Tether between chains just to use a cheaper one means an extra transfer and an extra chance to get it wrong. If you're funding a wallet from scratch and genuinely free to choose, TRON and Solana both keep sending cheap.
What happens if I send on the wrong chain?
The tokens arrive at that address on a chain nobody is monitoring. Sometimes an operator can recover them and sometimes the address doesn't exist in a usable form on that chain at all. Treat it as lost and check the label before you send instead.
Do I need an account to swap usdt to xmr?
No. The whole thing runs as two ordinary on-chain transactions: you send Tether from your own wallet, and Monero arrives at the address you named. There's nothing to register and nothing to top up first.
How long does a tether to monero swap take?
Most of the clock is confirmations on both sides. Your deposit needs to confirm on whichever chain you used, then the payout goes out and settles into Monero's two-minute blocks. It's usually a matter of minutes rather than hours, and a congested Ethereum is the common reason it stretches.
Why can't I spend the XMR the moment it arrives?
Every output you receive is locked for ten blocks, roughly twenty minutes, before it becomes spendable again. It's baked into the protocol. Your wallet may well show the amount before it shows it as available, which looks alarming and isn't.
Can I check my Monero balance in a block explorer?
You can't, and that's working as intended. Amounts and recipients aren't readable on the chain, so an explorer has no balance to display for an address. Open your wallet instead.
Should I take the fixed rate or the floating one?
Fixed locks your number immediately and costs more for the privilege. Floating keeps adjusting to the market while the deposit confirms, so you might end up slightly ahead or slightly behind. If a small move would bother you, pay for fixed.
Can I convert usdt to xmr now and reverse it later?
Yes, and the reverse trip has its own page here. Going back means picking the chain for the Tether you want to receive, which is a heavier decision than picking the one you're sending from — there's nothing sitting in your wallet to check against.
Is the USDT I'm sending the same thing as a dollar?
It's pegged to the US dollar, but it's a token issued by a company rather than the currency itself. Worth holding that distinction in mind whichever chain you keep it on.
