How It Works
Fluel provides a simple interface to swap your USDC for native gas tokens on any supported chain via third-party decentralised protocols. No bridges to figure out, no wallet extensions to install — just Telegram.
Open our Telegram bot and type /start. A secure wallet is automatically created for you by Privy, a third-party wallet infrastructure provider. No seed phrases to write down, no browser extensions to install. Your wallet keys are generated and held exclusively by Privy within hardware-backed enclaves (TEE) — Fluel never has access to your private keys.
Tell Fluel where to deliver gas tokens. This is your own wallet — MetaMask, Rainbow, Coinbase Wallet, or any EVM wallet you already use. Gas tokens are sent directly to this address, so you have full control from the moment they arrive.
/setwallet 0xYourWalletAddressSend USDC to your Fluel deposit address on any supported chain. This is a standard blockchain transfer — you can verify your deposit address on any block explorer. Your USDC stays in your managed wallet until you swap or withdraw it. Type /deposit to see your address.
Request a quote, review the details, and confirm. Fluel relays your instruction to LI.FI — a leading cross-chain aggregator trusted by major DeFi protocols — which finds the best route across bridges and DEXs and executes the swap on-chain. Native gas tokens are delivered directly to your destination wallet, typically within 30 seconds to 2 minutes depending on the chains involved.
/gas 5 base arbitrumGas tokens arrive in your external wallet ready to use. Mint NFTs, interact with DeFi, bridge tokens — whatever you need gas for. Changed your mind? Withdraw your full USDC balance at any time with /withdraw. There is no lock-up period and no withdrawal fees.
Where do my tokens go?
Your tokens follow a transparent, verifiable path. Every step happens on-chain and can be tracked with a block explorer.
Built on trusted infrastructure
Your wallet keys are generated and held exclusively by Privy inside hardware security enclaves (TEE). They never leave the secure environment — Fluel cannot access, view, or extract them.
Your swap instructions are relayed to LI.FI, a battle-tested cross-chain aggregator used by Jumper, 1inch, and other major DeFi applications. All swap execution happens on-chain via decentralised protocols.
Every transaction is recorded on public blockchains. You can verify your deposits, swaps, and withdrawals on any block explorer at any time.
Your USDC is never locked. Withdraw your full balance to your own wallet at any time with a single command. No waiting periods, no fees.
Transparent fees
Fluel charges a service fee on each swap. The fee is applied to the transaction amount before the swap is submitted to the underlying protocol — you see the exact amount in the quote before confirming. No hidden charges.
Minimum fee: $0.10 per swap. Network gas costs and bridge fees (set by Li.Fi, not Fluel) are shown separately in the quote.
Full transparency
All code is public on GitHub. Verify exactly what runs.
