What is Theta Fuel?
Theta Fuel, traded as TFUEL, is the operational token of the Theta network, a blockchain built around video streaming, bandwidth sharing, and edge computing. TFUEL acts as the gas that pays for on-chain activity, including transactions, smart contracts, and payments to users who relay video streams across the network. Theta uses a two-token design. THETA is the governance and staking token used to run validator and guardian nodes, while TFUEL handles the high volume of small payments the network needs day to day. TFUEL launched in 2019 alongside the Theta mainnet and can also be staked to help support the system and earn rewards. This split keeps a liquid token available for frequent micropayments while governance stays separate. You can follow the Theta Fuel price and hold TFUEL in a self-custody wallet.
