FERA is a way to **provide liquidity** (to be the counterparty that traders swap against) on Robinhood Chain, and get paid better for it than a plain liquidity pool would. It has two parts: 1. **A smart fee (the hook).** FERA runs on a Uniswap v4 "hook", a small piece of code that sets the swap fee *per trade, based on live market conditions*. When flow is dangerous to liquidity providers (violent memecoin moves, bots, weekend stock-token drift), the fee goes up. When flow is benign, the fee goes down. Traders always get to swap; they just pay what the moment is worth. 2. **A managed vault.** You deposit into a vault, receive a normal ERC-20 share token, and the vault runs a transparent, rule-based strategy for you. No keeper to run, no ranges to rebalance by hand. You can withdraw whenever you want. ## The core idea Ordinary liquidity providers lose money to two things: **volatile flow** (bots and sharp price moves pick them off) and **structural arbitrage** (tokenized stocks drift from their real price over the weekend, and someone arbitrages that gap at the liquidity provider's expense). FERA's bet is simple: **that flow isn't the enemy. It's underpriced.** Instead of trying to block bots or fight arbitrageurs, FERA charges them a fee that matches how toxic their flow is, and that fee goes to you, the liquidity provider. * **Memecoin pools:** the fee rises with realized volatility, from a floor of **0.34%** up to **3%** (and a hard cap of 5% on one-sided sell pressure). The more violent or mechanical the flow, the more you earn. Wash-trading and volume bots become a fee source by design. * **Tokenized-stock pools (RWA):** the fee is near-zero (\~2 bps) while the underlying market is open, and widens (30–100 bps) when it's closed, scaling with how far the on-chain price has drifted from the Chainlink oracle. The weekend arbitrageur pays you for the drift instead of taking it from you. The exact formulas, with worked numbers, are in [How the dynamic fee works](/feradotfun/for-liquidity-providers/how-fees-work.md). FERA does **not** change your impermanent loss. Over the same price path, your IL is the same as it would be in a vanilla pool. The entire difference FERA makes is **fee capture**: you collect more of the fees on the flow that matters. (See [Risks](/feradotfun/trust-and-safety/risks.md) for what impermanent loss is and why it still applies.) ## For a degen You already LP the hot WETH/memecoin pairs and chase emissions. FERA gives you: * **Higher fee capture on violent pairs.** The fee scales up exactly when the action is craziest. A dump that would bleed a vanilla LP instead pays an elevated (asymmetric) fee. * **A token to farm, honestly.** Depositing into the vault makes you eligible for FERA emissions (paid as esFERA). Directly LPing the same pool does *not* earn emissions. The vault is the only door to them. But read [Emissions](/feradotfun/tokenomics-and-transparency/emissions-and-tokenomics.md) first: early emissions are **small** by design, because emissions are capped by real protocol revenue. We are not selling you a fat emission APR. * **The "Active" risk profile.** On memecoin pools, a band near the price does the fee capture while a wide base holds your position through big moves, so the strategy earns from volatility instead of churning your principal to chase it. You still take impermanent loss when the price moves; that's the trade-off for the higher fee capture. ## For someone LPing NVDA You own tokenized stocks (NVDA, AAPL, GOOG…) and now they trade on-chain 24/7. You want to earn on the shares you already hold, without becoming a market maker. FERA gives you: * **The weekend-drift story, in your favour.** Your stock tokens drift from the cash price over the weekend and snap back at Monday's open. In a normal pool, that reconciliation is a recurring *loss* to you: you're the one being arbitraged. FERA's RWA fee turns that same drift into recurring *income*: the arbitrageur pays a widened fee to close the gap. * **The "Steady" risk profile.** Your liquidity sits in a wide range that stays in-range through crashes and rebounds, so less impermanent loss is realized. You earn a thinner but steadier slice of fees. It's built for exposure, not for running a trading desk. * **One-click, single-asset deposit.** Deposit one side; the vault handles the rest. A caution for this reader specifically: FERA provides **liquidity infrastructure**, not securities. We don't help you "invest in NVDA" or "buy stocks." Deposits to stock-token pools are geo-fenced by jurisdiction (swaps are never gated). See [Risks](/feradotfun/trust-and-safety/risks.md#rwa-and-geo-fencing). ## What FERA is *not* * **Not a yield product with a number on it.** There is no "X% APY." Your earnings depend on volume and volatility, both of which vary. * **Not a way to beat a professional market maker.** A skilled person hand-managing a tight range will typically capture more fees per dollar than the vault. The vault sells *management, emissions-eligibility, simplicity, and a risk-profile choice*, not higher yield than a pro. We're explicit about this because it's the easiest thing to overstate. * **Not an MEV solution (yet).** v1 *prices* toxic swap flow through fees. It does not auction the block or "capture the MEV." That's a v2 roadmap idea, not a v1 claim. * **Not custodial of your principal.** Money-path contracts are non-upgradeable; the protocol cannot pause your withdrawals or touch your principal. ## Where FERA runs Robinhood Chain is a permissionless Arbitrum Orbit L2 with \~100ms blocks, ETH for gas, and Chainlink as the chain's oracle infrastructure. Uniswap (v2/v3/v4) is the chain's primary AMM, and \~95 Robinhood-issued stock tokens trade there 24/7 alongside memecoins. FERA deploys pools for pairs that are *already trading*, so there's real flow to price from day one. *** Next: [How to LP →](/feradotfun/for-liquidity-providers/lp-guide.md) --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://fera-3.gitbook.io/feradotfun/what-is-fera.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
