 that allows LPs to keep their liquidity positions active while expressing an UP, DOWN, or RANGE view for each epoch. The testnet is now open for early testing, and we’d value feedback from the Arc community.

I’d like to introduce Limen, an AMM that my team and I have been building on Arc.

Traditional AMMs let LPs provide liquidity and earn fees, but they don’t offer a simple way to express a short-term market view while keeping the same position active.

Limen adds an optional layer called Stance. After providing liquidity, LPs can choose one of three views for each epoch:

The underlying LP position remains active and intact. Only the fees generated during that epoch are reallocated based on the outcome.

Swap → Add liquidity → Choose a Stance → Wait for settlement → Settle and claim

Limen is currently live on Arc Testnet with cirBTC/USDC and cirBTC/EURC markets.

At this stage, we’d especially appreciate feedback on:

• Whether the mechanism is clear at first glance

• Anything confusing or unnecessary in the interface

Please feel free to be direct. Honest criticism is more useful to us than generic encouragement. There is also a Feedback button in the top-right corner of the app.

Prerequisites: A compatible wallet and Arc testnet assets

Warning: Testnet only. Please use testnet assets only. Features and mechanics may change.
