A fee that defends the pool
The agent reads the real market price every block and widens the fee the moment the pool drifts off-market. Instead of draining your liquidity, arbitrage pays you for it.
Uniswap v4 hook · Robinhood Chain
Liquidity that prices its own risk.
The Marlin dynamic-fee hook moves the pool fee with volatility. Your liquidity earns more when markets get fast, and stays protected when they turn toxic. Provide liquidity on tokenized stocks and ETH paired with USDG, live on Robinhood Chain.

The hook
A smarter fee, working for you.
Most pools charge one flat fee no matter what the market is doing. The Marlin hook prices the fee to the moment, so liquidity providers keep more of the value their capital creates.
You keep the fee you earn
The hook only sets the fee, it never takes a cut. Every fee a pool charges on a swap goes to its liquidity providers pro-rata, and because it climbs with volatility, you capture more of it exactly when the market is moving.

How it works
Set the range. The hook does the rest.
You add liquidity once. From there the agent prices the fee to the market in real time, so you do not have to watch the tape to stay protected.
Reads the market every blockOn duty
Providing liquidity carries market risk and impermanent loss. Fees are not guaranteed.
- 01
Add liquidity
Pick a live pool, set a full or custom range, and deposit. Hold ETH? It is automatically wrapped to WETH when you add liquidity.
- 02
The agent watches
It compares the pool price to the real market price every block, tracking volatility and any off-market drift as it happens.
- 03
The fee adapts
When the market turns fast or the pool drifts off-market, the fee widens from its 0.10% base; when things are calm it eases back down.
- 04
You earn the fee
You collect the pool's trading fees pro-rata for as long as your liquidity is in range, and the dynamic fee means you capture more of it when volatility spikes.

The flagship token
Do not want to run a range? Hold $MARLIN.
This is separate from the hook. Every $MARLIN trade carries a 3% protocol fee, and 2.75% of it is routed into a protocol-owned liquidity book on high-volume tokenized-stock pools. Holders earn 80% of the fees that book earns, paid weekly. The principal is never unwound, so the payout compounds.

Provide liquidity
Add liquidity to the Marlin hook.
Deposit into a tokenized-stock or ETH pool paired with USDG, and let the dynamic-fee hook price your risk block by block. Your position stays in your wallet, and you keep the pool fees it earns. Experimental; liquidity carries market risk and impermanent loss.
