Stablecoins Are Wrapped Dollars That Live on the Blockchain

Stablecoins live on the blockchain, in your crypto wallet, rather than in a bank account. This is useful if you don't have a bank account and it's hard for you to set up a dollar-denominated bank account. Most of the big stablecoin issuers issue on multiple blockchains. You can collateralize non-crypto assets such as stocks or Ether with them.
