What payment options are available?

Authors can choose to sell books and withdraw their earnings either in USD to a bank account or in USDC to a digital wallet. Both authors and readers can opt to use USDC instead of a traditional USD bank card for payments.

USDC is a digital currency that is always equivalent to 1 US dollar. It is issued by Circle, a U.S.-based, heavily regulated company that provides regular audits to verify that every USDC token is fully backed by cash or U.S. Treasury bonds.
