Fenix Finance Questions Answered
Everything you want to know about trading, liquidity, token mechanics, and security on the Fenix Finance platform. For a deeper overview, visit the About Fenix Finance page or go back to the main app.
What exactly is Fenix Finance and what does it do?
Fenix Finance is a decentralized exchange and liquidity protocol built on the Blast network. It lets anyone swap tokens, provide liquidity, and earn trading fees — all without a central intermediary. The protocol combines concentrated liquidity pools (similar in concept to those popularized by Uniswap v3) with a native token, FNX, that gives holders governance rights and fee-sharing when locked. Blast's native yield on ETH and stablecoins flows directly through the platform, meaning liquidity providers earn yield from two sources simultaneously.
How is Fenix Finance different from other DEXes on other networks?
Most DEXes pass trading fees to liquidity providers and stop there. Fenix Finance runs on Blast, a Layer 2 chain that natively rebases ETH and USDB holdings — so idle capital inside the protocol keeps earning even when there is no trading activity. That dual yield is the core difference. Beyond that, the ve(3,3) tokenomics model means FNX lockers receive a share of protocol fees each epoch, aligning long-term token holders with protocol growth in a way that standard AMMs do not.
What is the FNX token and why does it matter?
FNX is the governance and incentive token of Fenix Finance. On its own, one FNX is a liquid ERC-20 asset tradeable on the open market. The real utility comes from locking: deposit FNX for a chosen duration and you receive veFNX, a vote-escrowed position. veFNX holders vote on which liquidity pools receive FNX emissions each week, and in return they collect trading fees and bribes from protocols that want their pool to attract more liquidity. Longer lock periods produce higher veFNX balances, which means proportionally more votes and more fee income.
How do I swap tokens on Fenix Finance?
Connect a Web3 wallet (MetaMask, WalletConnect, or any compatible wallet) to the main interface. Select the token you want to sell in the top input field and the token you want to receive in the bottom field. The router finds the best path automatically. Set a slippage tolerance — 0.5 % works for most liquid pairs — then confirm the transaction in your wallet. The swap executes on-chain and tokens arrive in your address within the same block.
Is Fenix Finance safe? Has it been audited?
The Fenix Finance protocol has been audited by two independent security firms: Hats Finance and Code4rena. Code4rena ran a competitive audit in September 2024 where independent researchers reviewed the codebase under an incentivized bug-bounty format. Hats Finance operates an ongoing on-chain bug-bounty program. No audit is a guarantee against all risks, but two separate reviews covering the same codebase substantially reduce the chance of critical undiscovered vulnerabilities. As with any DeFi protocol, users should only deploy capital they are prepared to lose in a worst-case scenario.
What fees does Fenix Finance charge for swaps?
Trading fees vary by pool type. Volatile pairs — assets whose prices move independently of each other — typically carry a 0.3 % fee per swap. Stable pairs, such as two different USD-denominated stablecoins, use a much lower fee, often around 0.01 %. A portion of every swap fee goes to liquidity providers in that pool, and another portion is distributed to veFNX holders each epoch. The exact fee split is governed by protocol parameters that veFNX holders can vote to adjust.
How do I add liquidity and start earning fees?
Navigate to the Liquidity section of the app. Choose a pool — ETH/FNX, USDB/ETH, or any other listed pair. For concentrated liquidity pools, you define a price range inside which your capital is active. Narrower ranges produce higher fee yields when the price stays within them, but your position earns nothing if the price moves outside. Wider ranges are more hands-off. Deposit both tokens in the correct ratio, sign the transaction, and you will receive an LP NFT representing your position. Fees accumulate in real time and can be claimed at any point.
What is impermanent loss and how does it affect Fenix Finance LPs?
Impermanent loss (IL) occurs when the price ratio of your deposited tokens changes after you add liquidity. You end up holding a different mix of assets compared to simply holding them in a wallet. IL is not unique to Fenix Finance — it affects every AMM, including Uniswap. Concentrated liquidity makes IL more pronounced because your exposure is amplified within the chosen range. The Blast native yield partially offsets this by continuously accruing ETH and stablecoin rebases on top of trading fees. For stable-to-stable pools, IL is very small because the prices rarely diverge.
Can I lock FNX if I already hold it elsewhere, like on a CEX?
You must first withdraw FNX to a self-custody wallet on the Blast network. Centralized exchanges hold tokens on their own infrastructure and do not expose the underlying on-chain mechanics. Once your FNX is in your Blast wallet, go to the Lock section of the Fenix Finance app, choose a lock duration, and confirm the transaction. The minimum duration is one week; the maximum is four years. Locking converts your FNX into a non-transferable veFNX NFT position.
What is Blast and why was Fenix Finance built on it?
Blast is an Ethereum Layer 2 network that passes native ETH staking yield and T-bill yield back to users automatically. Most L2s hold bridged ETH in a contract that earns yield for the operator; Blast returns that yield to wallets and contracts instead. For a DEX, that means liquidity sitting inside pools earns a base return even between trades. The Fenix Finance team chose Blast specifically to combine this passive yield layer with active trading fee revenue, creating a product that competes with ve(3,3) DEXes on other chains while offering an additional yield source no other network currently provides at the protocol level.
Why would a protocol pay bribes to veFNX voters?
External protocols — typically other DeFi projects — need deep liquidity for their own tokens. They cannot force Fenix Finance to direct FNX emissions toward their pool, but they can pay incentives (called bribes) to veFNX holders who vote for their pool in the weekly gauge. It is rational: if a protocol pays $10,000 in bribes and receives $50,000 worth of FNX emissions that attract liquidity, the trade is clearly worthwhile. veFNX holders get paid to vote. The protocol benefits from diverse, competitive demand for votes. Everyone has an aligned incentive — which is the idea behind ve(3,3) tokenomics as a category.
How does the weekly epoch system work?
Time on Fenix Finance is divided into epochs of roughly seven days. At the start of each epoch, veFNX holders cast their votes on which liquidity pools should receive FNX token emissions during that period. Votes determine the split of newly minted FNX distributed to LPs as farming rewards. At the end of the epoch, fee revenue and bribes collected during that period are distributed to voters proportionally. Your veFNX balance at the snapshot time is what counts — late top-ups within an epoch may not register until the following period.
What happens to my veFNX when the lock expires?
When your lock period ends, the veFNX position converts back to standard FNX at a 1:1 ratio. You can withdraw the underlying FNX to your wallet at any time after expiry. While locked, the position cannot be transferred, but it can be extended or topped up with more FNX at any point before expiry. Some users choose to keep extending their lock to maintain voting power; others let it expire and exit their position. The choice depends entirely on how you weigh ongoing fee income against liquidity preferences.
Does Fenix Finance have a referral or points program?
The Fenix Finance team has run points campaigns tied to Blast's own points and gold distribution system. Users who traded, provided liquidity, or locked FNX during active campaign periods accumulated Fenix Finance points that factored into airdrop allocations. Whether a new campaign is currently active depends on the team's current roadmap — check the official Discord and Twitter for the latest announcements. Blast Gold, separately distributed by the Blast team itself, has also been allocated to active Fenix Finance users in prior rounds.
Where can I follow Fenix Finance updates and get support?
The primary channels are Twitter (@fenixfinance), Discord (discord.com/invite/fenixfi), and Medium for longer-form posts. The technical documentation lives on the official docs site. For protocol-level questions and governance discussions, Discord is the most active venue. For a structured overview of what Fenix Finance is building, the About Fenix Finance page on this site is a good starting point.
