The $XPL token is the fuel and security backbone of the Plasma network. While the protocol famously offers zero-fee USDT transfers (funded by a protocol-managed paymaster), $XPL is required for all other activities, including complex smart contract executions, governance voting, and validator staking. To secure the network, users stake $XPL to validators, who in turn receive rewards. As of early 2026, the launch of native staking has become a primary driver for token demand, as it allows holders to earn yield while reducing the circulating supply.
