Monero (XMR) perpetual futures on Polymarket track the spot price of Monero in USD, with no expiry. XMR is the native token of Monero, a privacy-focused proof-of-work cryptocurrency that hides the sender, receiver and amount of every transaction by default. Monero launched in April 2014 as a fork of Bytecoin's CryptoNote code, started by a pseudonymous developer known as thankful_for_today and developed since by an open-source community, and XMR is used for private payments and transaction fees. Its privacy relies on ring signatures, stealth addresses and Ring Confidential Transactions (RingCT), so privacy is mandatory rather than opt-in.
