DLMM, explained — and what Dungeon Labs is building with it

A plain-language guide to the technology behind JanusDLMM, and how it helps teams and liquidity providers earn more from their markets.

Start here: what is “liquidity,” really?

Every time someone buys or sells a token on a decentralized exchange, they’re trading against a pool of money called a liquidity pool. Think of it as an automated exchange booth. People deposit two assets into it (say, a token and USDC), and the booth uses that money to fill everyone else’s trades, setting a price automatically based on how much of each asset it currently holds.

The people who put money into the booth are liquidity providers, or LPs. They’re lending their assets to the pool, and in return they earn a cut of the fees every time a trade goes through. More trading means more fees for the LPs.

So the basic loop is simple. Traders need a pool to trade against. LPs supply that pool because they get paid to. And when the pool is deep and healthy, trading is smoother for everyone involved.

The old way, and why it wastes money

The first pools of this kind had a quiet flaw. They spread an LP’s money across every possible price, from almost zero all the way up to infinity.

Sounds thorough. In practice it’s wasteful. A token might really only ever trade between, say, $1 and $2, but the pool still parks most of the LP’s money at prices like $0.01 or $500 that are never going to happen. That money just sits there earning nothing. Only the thin slice sitting near the price people are actually trading at does any real work.

Which meant LPs were tying up large amounts of capital to collect fees on a small fraction of it. The money was there. It just wasn’t doing anything.

Enter DLMM: liquidity with precision

DLMM stands for Dynamic Liquidity Market Maker, and it fixes that waste by changing how liquidity gets placed.

Rather than smearing money thinly across all prices, a DLMM chops the price line into discrete steps called bins. Picture the rungs of a ladder, each rung being one specific price. LPs pick which rungs to put their money on, so they can concentrate it right where trading is actually happening.

A few things fall out of this.

First, trades inside a bin have zero slippage. On a single rung the price doesn’t move as people trade, so you get a clean, exact fill. When trading pushes the price up or down, it just steps to the next rung over.

Second, your capital works much harder. Since LPs only put money on the rungs near the real price, far more of it is busy earning fees instead of idling. The same deposit ends up providing deeper, more useful liquidity.

Third, you get to choose a “shape” for how your money sits across the rungs:

• Spot: spread evenly across a range. Simple, balanced, low-maintenance.
• Curve: packed tightly around the current price, which earns the most when things are stable.
• Bid-Ask: pushed out to the edges of your range. Good for volatility, and it quietly buys low and sells high as the price swings.

It’s a real step up. For the first time, an LP has the kind of fine control over their position that professionals always wanted.

The catch: DLMM is powerful, but it’s work

This is where most people get caught out.

Your money only earns fees while the price is sitting on the rungs you chose. That live rung is called the active bin. The second the price wanders off your rungs, your liquidity goes quiet and stops earning, and it stays quiet until you move it back to where the trading is.

Markets, of course, never hold still. The price drifts all day and all night. So to keep earning, an LP has to keep repositioning, lifting their liquidity and setting it back down on whatever rungs the price has moved to, and reshaping it as conditions shift.

By hand, that’s a brutal job. It never really stops, it’s technical, and if a big move happens while you’re asleep your liquidity can get stranded somewhere off to the side, earning nothing. Most teams and most LPs just don’t have the time or the tooling to keep up with it, so they end up leaving most of what DLMM can do on the table.

That gap is the reason Dungeon Labs exists.

The missing piece: this is just market making

To get what’s really going on here, look at how ordinary financial markets run.

In any serious market you’ll find professionals called market makers. The job is to always be there and always be quoting. They post a price they’ll buy at (the bid) and a price they’ll sell at (the ask), and they make money on the gap between the two, the spread, across a steady stream of trades. As the market moves they keep nudging their quotes and keep an eye on the inventory they’re holding. They’re the quiet machinery that keeps a market liquid and orderly, and doing it well is a serious, full-time craft.

Now go back to the DLMM LP. Liquidity on the rungs below the price is just an offer to buy, which is a bid. Liquidity on the rungs above is an offer to sell, an ask. The fees you collect are the spread. And shifting your liquidity as the price moves is nothing more than updating your quotes.

So here’s the thing worth sitting with: managing a DLMM position well is market making. Same craft the pros have run for decades, only now it lives on-chain, in code. The catch is that the people who’d benefit most from it usually can’t run it themselves.

What Dungeon Labs is building

Dungeon Labs makes tools that hand on-chain teams the sort of capabilities that used to belong only to professional trading firms. The first of them is JanusDLMM.

JanusDLMM is an automated, on-chain market maker. It takes the grind of DLMM management off your plate and runs it for you, day and night. It watches the pool live, runs real market-making strategies (bid-ask, curve, and others), and keeps shuffling liquidity across the bins so it stays where the trading actually is. When the price runs or volatility kicks up, it reacts and repositions instead of letting your liquidity sit stranded.

Think of it as a trading desk that never clocks out. It quotes both sides, works the spread, manages the position as things change, and does all of it on-chain, without you ever having to hire a market-making firm or babysit a screen.

Who this helps, and how

Token teams. A token is only as healthy as its liquidity, and JanusDLMM keeps that liquidity awake and working. Traders get tighter, deeper markets with less slippage, the project looks more serious, and far more of the fees that were always available actually get captured instead of slipping by. Liquidity stops being a thing you set up once and cross your fingers over, and becomes something that’s genuinely managed for you, minus the cost of bringing in an outside firm.

Liquidity providers. Normally you place your liquidity, then watch it drift out of range and go silent. Here it’s kept in range and kept earning. The aim is plain enough: keep your capital where the fees are, move with the market, and collect more of what your position could always have earned.

Underneath, it’s one idea both ways. DLMM made it possible to provide liquidity like a pro. Dungeon Labs is what makes it practical, so a team or an LP can earn the way market makers do without having to become one.

Note: liquidity provision and trading carry market risk, and any fees earned depend on real trading activity and market conditions. None of this is a promise of returns or financial advice.
