Odaily Planet Daily News: Matt Hamilton, a former executive of Ripple, tweeted that XRP Ledger is the first blockchain to support so-called stablecoins. On XRPL, this type of asset is named and called an IOU (loan note). Users lend $1,000 in exchange for 1,000 USDC, and Circle will return it on demand. Such a system requires users to clearly determine how much they trust their counterparties. With the advent of Ethereum, people called these things "stablecoins" and began to view them as assets in themselves, rather than IOUs for other assets.
