⚡| DLMM Pools

The DLMM (Dynamic Liquidity Market Maker) protocol feature allows to concentrate liquidity into single "bins", which leads to more efficient and flexible liquidity provisioning and seamless trading experiences with zero slippage and low fees.

With DLMM, liquidity providers can provide liquidity within a specified price range in any amount of their choice - this is called "Concentrated Liquidity". Using a $USDC-$USDT pool as an example: If an liquidity provider chooses to provide liquidity between $0.99 and $1.01 then the LP will earn trading fees as long as the price is within that active trading range.

When someone makes a token swap or trade, a transaction fee will be charged. For all SectorOne DLMM pools 80% of that earned trading fees goes back to the liquidity providers and 20% of that earned trading fees go to the $ONE token stakers. All earned fee rewards are automatically compounded back into the active bin where trading happens. When a user withdraws his LP, he also collects all accumulated trading fee earnings together with his provided liquidity.

Bins in DLMM Pools

Bins

To allow concentrated liquidity, the price curve is discretized into "bins", which is similar to the "tick"-concept in Uniswap V3. The main difference however, is that DLMM protocols use the "Constant Sum"-price formula instead of the "Constant Product"-price formula.

Bin Steps

What this means is that each bin represents a single price point and the difference between two consecutive bins is the "bin step" parameter. Take for example the $USDC-$USDT pool again*: If the current price is $1 and the bin step setting is 1 basis point (i.e. 0.0001 or 0.01%), then the next consecutive bins up are 1 x 1.0001=$1.0001, 1.0001 x 1.0001=$1.00020001 etc. *Note that this is the geometric sequence.

In addition to using a different price calculation, bin steps are not restricted to one basis point. The "bins step" pool setting is a non-adjustable parameter, which can only be set-up by the initial pool creator. Because of this, there can be multiple DLMM pools of the same token pair, that differ only in their bin step and/or the base fee pool settings.

Impermanent Loss Keep in mind that providing liquidity could be subject to impermanent loss and it may carry certain risks. Make sure you are aware of all the pros and cons of providing liquidity into a concentrated liquidity pool before taking any actions. You can learn more about impermanent loss by clicking here.
