Plasma uses PlasmaBFT consensus for fast finality under 1 second and over 1000 TPS, making it ideal for high-volume payments. It supports EVM compatibility for easy smart contract deployment and includes a Bitcoin bridge for native BTC use via pBTC. A built-in paymaster enables gas payments in stablecoins like USDT without extra fees.
The paymaster acts as a network-sponsored relayer that automatically pays gas fees from a controlled XPL allowance for verified simple USDT transfers. Users interact with the official USDT contract, and the system checks eligibility before subsidizing costs, ensuring recipients get the full amount without deductions.
Plasma operates a free lane for basic stablecoin transfers (slower confirmation) and an express lane for priority or complex transactions (with fees). Custom gas options allow payments in USDT or BTC if needed, while the free path relies on fee abstraction for everyday use.
