Questions
Short answers to what people ask most.
Yes. A stablecoin is a cryptocurrency built to track a reference asset, usually the US dollar, through cash reserves, crypto collateral or other mechanisms.
Most cryptocurrencies float freely in price. A stablecoin aims to hold a fixed value, usually one dollar, and its issuer often promises to redeem it.
Fiat-backed coins such as USDT and USDC hold cash and short-term government debt and redeem tokens for dollars. Crypto-backed coins lock more collateral than they issue.
The coins can land at an address the receiver does not control on that network, and getting them back depends on the receiving exchange or wallet. Match the network on both sides.
Fees follow demand for block space, so busy hours cost more than quiet ones. Check the estimate in your wallet before you send.
