描述
Fables is a market-aware ve(3,3) decentralized exchange built on Uniswap v4 and live on Robinhood Chain. Our vision is to bring the best hook ideas together into the most efficient AMM infrastructure onchain, and to become the go-to liquidity layer on Robinhood Chain.
We launched early on Robinhood Chain, before deep incumbent pools had formed, which gave room for our first efficiency improvement: dynamic fees. Our fees reflect the market each pool serves and price in toxic flow. On ETH/USDG they rise with volatility and price deviations. On tokenized stocks they also follow market hours, rising around the open and close when new information arrives and easing when markets are calm, such as at weekends, while guardrails raise them whenever a thin market turns frantic. Fees also adapt to other venues on Robinhood Chain. The aim is to compensate LPs for the risks they take while keeping execution competitive.
On Fables, LPs manage liquidity and staking, while token holders manage locks, voting and rewards. Staked LPs earn FABLES emissions. veFABLES holders vote on weekly allocations and receive pool fees and partner incentives.
Lastly, we plan to ship Super Hooks that combine the best hook features in a single implementation, building on our work in dynamic fees and LP incentives. One example is liquidity rehypothecation, which adds lending yield on top of swap fees and is practical thanks to low gas costs on Robinhood Chain.

Contracts
This weekend we built and released the v2 of our live hooks as a public, audit-ready repository.
Compared with the hooks live today, v2 adds:
- lower fees for chosen takers, through per-pool sender discounts (for example for partner routers) that can never raise a fee or go below the floor
- a gas-optimized swap path written in assembly and checked against a plain-Solidity twin by differential tests
- direction-specific dynamic fees in every build, for ERC-20 and native-ETH pools, plus an optional continuation fee that charges more for trades chasing a fresh move
- wider but safer bounds, with a fee floor down to 0 (from 0.01%), a hard 10% cap on every build, and keeper fee raises paced at one step per minute
- a new stable-pair hook that runs Uniswap's StablePair fee together with our LP ledger, staking and discounts in one pool, open to any LP or ledger-only, with added protection from a 10% fee cap and a price window against parked-price tricks
- optional ledger-only liquidity builds
560 tests pass on a fresh clone, including OpenZeppelin's Uniswap-hooks invariants, an ERC-6909 conformance suite and fork tests on live Robinhood Chain state. We also ran an internal security pass of the final code, with no open findings.
App Update (live on fables.fi)
- Redesigned position and lock views, with clearer staking steps in deposit, withdrawal and repositioning flows, plus simpler lock creation, extension and merging
- Reworked rewards with hourly emissions history, per-lock voting rewards, and separate accruing, verifying and claimable amounts
- A new Vote page and incentive form with allocation controls, weekly charts, total and per-week incentive amounts, and a week calendar
Go-to-market
At Founder House, we met interesting builders and are in talks with some about partnering in the future. We also used user feedback to iterate on the UI/UX and on features such as lock merging. On Saturday, we also started reaching out to existing and potential LPs, directly following feedback from our first Mentorship session.
