What are stablecoins and why they are convenient for transfers
A stablecoin is a digital token that is meant to stay worth exactly one unit of a regular currency, usually the US dollar. The two biggest are USDT (issued by Tether) and USDC (issued by Circle).
A digital dollar, roughly speaking
When you hold 100 USDT, the idea is simple: it should be worth 100 US dollars today, tomorrow and next month. The issuer keeps reserves (cash and short-term government bonds) and promises to exchange tokens for dollars 1:1. Because the price does not jump around like Bitcoin, people use stablecoins as a place to park money and as a way to move it.
The token itself lives on a blockchain. That is what makes it transferable: you can send it from your wallet to any other wallet in the world without a bank in the middle.
Why people use them to move money
- The amount arrives as sent. There is no exchange rate inside the transfer: 500 USDT out, 500 USDT in, minus a small network fee.
- Fees are small. On networks like Tron, TON or Solana a transfer usually costs cents; on Ethereum it can be a few dollars when the network is busy.
- It works 24/7. Weekends, holidays and bank cut-off times do not exist. A transfer typically settles in seconds to a few minutes.
- No paperwork per transfer. Once you have a wallet, you do not fill in a form for every payment.
Networks: the part that confuses people
The same USDT exists on several blockchains: Ethereum (ERC-20), Tron (TRC-20), TON, Solana, Polygon, Arbitrum and others. They are not interchangeable. If you send USDT on Tron to an address that only accepts USDT on Ethereum, the money can be lost.
The rule is easy: the sender and the receiver must pick the same network. Wallets usually show it next to the address; when in doubt, ask the receiver which network they expect.
Where the cost actually is
The transfer itself is cheap. The cost sits at the edges: buying stablecoins with a card or a bank transfer (the on-ramp) and turning them back into local money (the off-ramp). Each service charges a spread or a fee there, and this is where offers differ by a few percent. Our converter compares exactly that: how much you end up with after the whole path.
What to keep in mind
A stablecoin is only as good as its issuer and its reserves. USDT and USDC have held their peg for years, but the promise is made by a company, not a central bank, and there is no deposit insurance. Keep your wallet's recovery phrase safe: nobody can restore it for you. And most services that sell stablecoins for fiat will ask for identity verification (KYC) above a small amount.
