Documentation

J.T. Marlin is an onchain markets project on Robinhood Chain (Chain ID 4663). You connect a self-custody wallet and interact directly with onchain contracts. The firm never holds your keys and can never move or freeze your funds.

Everything is experimental digital-asset software. There is no bank, no broker, and no registered security. You are responsible for your wallet, your keys, and every transaction you sign.

Every $MARLIN trade carries a 3% protocol fee, and 2.75% of it is auto-rotated into protocol-owned liquidity on the highest-volume tokenized-stock pools, where order flow is heaviest and fee capture is strongest (0.25% funds operations, and a separate 1% covers the PONS trading rail). The protocol owns those LP positions and never unwinds them, so the book compounds: the positions earn trading fees around the clock, 80% of those LP fees is distributed to holders every week, pro-rata, and as the book grows the weekly payout grows with it. The desk keeps the remaining 20%, reinvested to keep scaling the book, plus the principal.

Holders pick and manage nothing. You hold one token and the weekly yield lands in your wallet. The agent selects and rotates the pools; the protocol owns the positions and keeps the principal working.

Hold $MARLIN and get paid, every Friday. The protocol-owned LP book earns trading fees around the clock, and 80% of that yield is distributed to holders once a week, every Friday at 18:00 UTC. There is nothing to stake and nothing to claim; the payout lands in your wallet.

Paid in the top stock, weekly. Rewards are sent in the week's top-ranked stock token, the same name the agent weights the book toward, not in $MARLIN. One token to hold, exposure to the strongest pool of the week.

Pro-rata by balance. Your share equals your $MARLIN balance divided by the eligible supply at the Friday 18:00 UTC snapshot. Wallets only; contracts (pools, routers, the desk) are excluded so the yield flows to real holders.

Nothing to claim. No staking, no lockup, no claim transaction. Hold the token and the distribution arrives in your wallet automatically.

As the book grows, the weekly payout can grow with it, but nothing is guaranteed. Payouts depend on $MARLIN trading volume and the fees the pools actually earn, and can be small or zero. See the live payout on the rewards page and the live book on the $MARLIN page.

Rotation and payout cadence: Weekly · Fridays · 18:00 UTC. The agent re-weights the book and the weekly distribution settles at that boundary. Planned supply is 1,000,000,000 MARLIN, a fixed design parameter.

There is no desk fee on marketplace buys or sells. Stock-token orders route directly through Uniswap to the best onchain price, so the only costs are the underlying pool fee (already baked into the quote you see) and network gas. The token settles to your own wallet. There is no lockup and no spread markup.

The marketplace lists tokenized stocks and ETFs, plus real-world assets such as gold and money-market tokens, all on Robinhood Chain. Each stock token tracks the price of a listed company but is a separate digital asset. Holding one is not the same as owning shares and carries no shareholder rights, votes, or dividends.

The Tape reads every meme and token pair trading against a tokenized stock on Robinhood Chain launchpads, such as PONS and other Robinhood Chain venues, and maps them in one place: pairs, 24h volume, liquidity, price, and an estimated fee APR. It is a live view of the ecosystem forming around each stock token. A local crawler indexes the pairs on a schedule; the site only reads them.

The Tape opens with a ranked list of the best pools to add liquidity to. Instead of raw APR, which runs off the chart on thin launchpad pools, each pool is scored on real fee income (volume times fee), liquidity depth, and stability, so deep, productive pools rank above violent, low-liquidity pumps. Pick a stock token to see its pairs, and open any token for its own page with stats, socials, and every stock pool it trades in.

Tokens on the Tape are third-party and unaffiliated with J.T. Marlin. Many are new, thin, and highly volatile. Nothing here is investment advice.

From a token page you can provide liquidity to its Uniswap pool directly from your wallet. Pick the protocol and fee tier (Uniswap v3 or v4), choose a price strategy (full range, stable, wide, or one-sided), and set the amount with USD presets. The LP position is minted as an NFT straight to your wallet and stays in your custody; you earn that pool's trading fees pro-rata.

This is standard Uniswap liquidity on a third-party pool, separate from the protocol-owned Book and from the $MARLIN holder payout. The Marlin dynamic-fee hook is listed as a coming-soon option and does not govern these pools yet. Providing liquidity carries market risk and impermanent loss, and launchpad pools can run their own hooks and may reject deposits, so try a small amount first.

Book is J.T. Marlin's protocol-owned liquidity, held on tokenized-stock pools. $MARLIN routes 2.75% of every trade into it, the desk manages the positions, and the principal is never unwound, so the book keeps working and compounding. You can read every position live, its value, range, and uncollected fees, on the Book. $MARLIN holders earn 80% of the fees this book makes, paid weekly, every Friday at 18:00 UTC.

Your Portfolio is where you track your own positions, fees, and activity. Public liquidity provision is now open: you can add liquidity to a Marlin hook pool directly from your wallet, the LP NFT is minted to you and stays yours, and you earn that pool's trading fees pro-rata. That is your own fee income, separate from the $MARLIN holder payout. The META/USDG pool is live today, with more stock pools opening soon.

The Marlin dynamic-fee hook is a Uniswap v4 hook that defends liquidity providers against arbitrage. It is approved and live on Robinhood Chain, governing the META/USDG pool today with more stock pools being brought on. When a pool runs on the hook, an off-chain keeper reads the live stock price about once a minute and, when the pool price drifts from it, writes a bounded, self-expiring fee override on-chain.

The override is one-sided: it taxes only the toxic, arbitrage side of a price gap, so ordinary buyers and sellers keep paying the base fee while LPs keep more of what the pool earns. The surcharge scales with realized volatility, and protective guards, a trading halt, a stale price feed, or an implausibly large gap, freeze the pool at its cap so nobody trades against a bad price. The floor, cap, and time-to-live all live on-chain, and if the keeper stops, the override lapses and the pool returns to its base fee.

Providing liquidity still carries market risk and impermanent loss, and trading fees do not guarantee a profit. Every override is bounded and verifiable, so any wallet can check exactly what the hook did on Robinhood Chain.

The Marlin Score is an internal ranking the agent computes for every eligible tokenized-stock pool from live onchain data: activity, fee efficiency, liquidity depth, volume, and volatility. It is a ranking tool, not a rating, a price target, or advice.

The agent monitors pools in real time and rotates the protocol-owned book toward whichever pools are generating the most fees, including stock pools that spike when a meme token begins trading against them. It re-weights on the weekly cadence and keeps positions in range.

Access to this site and any tokens or markets described here is provided as-is. You use them at your own risk. Digital assets are volatile. Smart contracts can fail. Markets can go to zero. You are solely responsible for your wallet, your keys, your transactions, and any loss that follows.

J.T. Marlin does not claim to be a broker, dealer, exchange, investment adviser, bank, or issuer of registered securities. Tokens on this site are experimental digital assets. Stock tokens may track a listed company's price without giving you shares, voting rights, dividends, or any claim on the underlying company.

J.T. Marlin has three separate products. Fees are not the same on each one.

Marketplace. You buy and sell tokenized stocks, ETFs, and other real-world assets at live prices. There is no desk fee on any buy or sell of the token itself. Orders route directly through Uniswap to the best onchain price, so you pay only the underlying pool fee (already in the quote) and network gas. The token settles to your own wallet. There is no lockup.

Liquidity.The protocol owns a live liquidity book on tokenized-stock pools, called the Book, managed by the desk; its principal is never unwound. You can now provide your own liquidity through the Marlin v4 dynamic-fee hook, live today on the META/USDG pool: you add liquidity to a hook pool directly from your wallet, the LP NFT is minted to you and stays in your custody, and you earn that pool's trading fees pro-rata. There is no desk fee to provide liquidity; you pay only the pool fee and gas. A keeper sets the pool fee within on-chain bounds to tax arbitrage, but it can never move or take your position. Providing liquidity can lose value: positions are exposed to impermanent loss and the trading fees earned do not guarantee a profit.

$MARLIN. A token that turns its own trading fees into a protocol-owned liquidity book. Each $MARLIN trade carries a 3% protocol fee, plus a separate 1% PONS trading rail (4% total). Of the 3%, 2.75% of each trade is auto-rotated as liquidity into the highest-volume tokenized-stock pools, selected by the agent and re-weighted weekly, where order flow and fee capture are strongest; the remaining 0.25% funds protocol operations. J.T. Marlin owns these LP positions and retains the principal; they are never unwound or handed out, so the book compounds and grows over time. The agent manages these positions actively, monitoring pools in real time and repositioning liquidity toward whichever pool is generating the most fees, including stock pools that spike when a meme token begins trading against them. The positions earn trading fees continuously, and 80% of that yield is distributed to holders every Friday, pro-rata by balance; the desk retains the other 20%, reinvested, plus the principal to keep scaling the book. As the book grows, the weekly distribution can grow with it, but nothing is guaranteed. Wallets only; contracts are excluded. $MARLIN is live on Robinhood Chain; its contract address is published below. Payouts depend on $MARLIN trading volume and the fees the pools actually earn, and can be small or zero. LP positions are exposed to impermanent loss, and the liquidity position and underlying stock can lose value.

Nothing on this site is investment, financial, legal, or tax advice. Nothing here is a recommendation, solicitation, or offer to buy or sell any security or other asset. The Marlin Score is an internal ranking tool, not a rating or a price target. Content is informational only. You decide whether to use the software and you accept the outcomes.

Only use funds you can afford to lose entirely. If you need advice about your situation, speak with a licensed professional where you live. Regulatory treatment of digital assets varies by jurisdiction and can change.

Always confirm the contract address your wallet displays before you sign anything. Reach an explorer yourself rather than through a link you were sent, and verify the address before you transact. Only use addresses published on this site.

Marketplace trades route directly through Uniswap to the best onchain price, with no desk fee. You pay only the pool fee (already in the quote) and gas. You hold your own tokens, and every buy and sell settles to your wallet. Liquidity you provide through the Marlin hook is your own Uniswap v4 position; the LP NFT is minted to your wallet and the hook only sets the pool fee within on-chain bounds. The $MARLIN contract address is published above; ignore any token claiming that name at any other address. Software can still contain bugs. Audits, if any, do not remove risk. Use at your own risk.
