Theta Fuel (TFUEL) is the native gas and utility token of Theta Mainnet, Theta Network's own Layer-1, EVM-compatible blockchain. It is not an ERC-20 or SPL token on Ethereum, Solana, or BNB Chain.
TFUEL pays for on-chain operations on Theta Mainnet, including smart contract gas fees and relay/bandwidth payments for video sharing. It is also distributed as a staking reward to THETA stakers, Guardian Node operators, and Elite Edge Node operators. As of 2026-08-31, its role has expanded alongside Theta EdgeCloud, the network's GPU/AI-compute marketplace.
TFUEL's distinguishing feature is Theta Network's split between a governance token (THETA) and a dedicated operational token that captures network usage through fee burns.
100% of gas fees and a portion of Edge Network payments are burned, tying TFUEL's net emission directly to actual on-chain activity rather than speculation alone. As of 2026-08-31, TFUEL's market capitalization was $65,451,657, trading 91.26% below its all-time high. The network's current growth narrative centers on Theta EdgeCloud, an AI/GPU compute marketplace, shifting TFUEL's demand driver beyond its original video-streaming use case.
TFUEL is a utility token, not a governance token; voting power on Theta Network rests with THETA, not TFUEL.
TFUEL has no maximum supply; it is an inflationary token with a partial offsetting burn mechanism.
Because there is no maximum supply, a fully diluted valuation is not meaningful for TFUEL.
TFUEL launched via free distribution to existing THETA holders when Theta Mainnet went live on March 15, 2019, rather than through an ICO.
At the mainnet snapshot, holders received 5 TFUEL per 1 THETA held, producing an initial supply of 5 billion TFUEL against THETA's 1 billion supply. THETA itself had been sold earlier, in a 2017-2018 token sale raising $20,000,000 ($12.8 million private pre-sale, $7.2 million public crowdsale at $0.1331 per THETA), backed by Samsung, Sony, Sierra Ventures, Heuristic Capital, and The Venture Reality Fund.
TFUEL runs on Theta Mainnet, Theta Network's own Layer-1, EVM-compatible blockchain, secured by a two-tier, multi-level BFT consensus design.
A committee of roughly 20-30 Enterprise Validator Nodes — historically including Google, Samsung, Sony, Creative Artists Agency, Binance, Blockchain Ventures, DHVC, and gumi — proposes and finalizes blocks. A second layer of community-run Guardian Nodes, potentially numbering in the thousands, seals blocks and checks validator behavior, adding a decentralization check on the validator committee.
Theta Network was co-founded in 2017 by Mitch Liu (CEO) and Jieyi Long (CTO).
Theta Labs, Inc. is the company that develops and maintains the Theta blockchain protocol and Theta EdgeCloud, a blockchain-powered decentralized cloud for AI, media, and entertainment workloads.
Samsung and Sony are cited as investors in the project. Theta's enterprise validator/governance council has included Google, Samsung, Sony, Creative Artists Agency (CAA), Binance, Blockchain Ventures, DHVC, and gumi.
Theta Network uses a two-token, two-tier governance and consensus model in which THETA, not TFUEL, carries staking and voting weight.
THETA is staked to run either Enterprise Validator Nodes or community Guardian Nodes (originally requiring a minimum stake of approximately 1,000 THETA), which together propose, finalize, and check blocks. A protocol upgrade lowered the Validator Node staking threshold from 2,000,000 THETA to 200,000 THETA to broaden participation. TFUEL is not a governance or voting token; it is generated as a staking reward and consumed for on-chain operations.
Theta Network's 2025-2026 development has centered on expanding Theta EdgeCloud, its decentralized GPU/AI-compute marketplace, and repositioning the ecosystem around an "AI agent economy."
CertiK Skynet's one recorded audit for the Theta ecosystem covers the TDROP token contract, not TFUEL or the core Theta Mainnet protocol.
The audit, requested December 13, 2021 and completed December 28, 2021, used static analysis and manual review. It found 0 Critical, 1 Major (a centralization-related finding, acknowledged but not resolved), 0 Medium, 2 Minor (resolved), and 4 Informational (resolved) issues — 6 of 7 findings resolved. No audit of the Theta Mainnet consensus code or the TFUEL token logic itself was identified.
