Liquidity with a rising floor. 3% swap fee builds a floor that only moves up, pays WETH yield to depositors. Live on Robinhood Chain. $PLINTH @Dan_anthony1
Plinth is a Uniswap v4 hook, not a protocol with a switch. The floor is a WETH bid ratcheted by swap fees — the hook rejects any call that sets it lower. That's the entire safety guarantee: one comparison, no exemptions, no whitelist. Code, not promises.
What it is
Plinth is a liquidity vault on Robinhood Chain, implemented as a Uniswap v4 hook around its own $PLINTH/WETH pool. The thesis: the floor only ever moves up.
Mechanism — a ratcheted floor
- Every swap pays a 3% fee: 1.20% is laid under the price as permanent WETH liquidity, 1.20% goes to depositors, 0.60% funds operations.
- The floor is ratcheted inside the hook — it has no downward path. The hook rejects any call that would lower it: "the whole guarantee is one comparison."
- A keeper converts coin-side fees to WETH and pushes the bid up; each lift is a course, recorded in an on-chain ratchet blotter.
Trust model
No admin key, no second token, no points program, no launchpad — the vault wraps its own pool and nothing else. Hook, keeper and position NFTs are pure code, and nothing is reversible.

How the floor is built:
1. Every $PLINTH swap pays a fee
2. Fees settle as WETH
3. WETH joins the floor
4. The floor never moves down
Locked. Lifted. Permanent.
swap fees flowing
The floor — rising with every course
only up
The ledger — every lift recorded, readable by anyone The positions — tokenized as NFTs, carried in wallets
Not a promise. On chain now.
