Pools don't have to be 50/50 or just two tokens 🪎

Weighted liquidity pools let you choose how much of each token you hold. That means less impermanent loss on the token with the bigger weight, less paired capital to launch a token, and up to 10 tokens in one pool.

Why they never became the default and how Coffer fixed it👉Weighted Pools Explained

33.1% APY on Coffer's USDC/USDT pool 👀

7-day average per DefiLlama. Leverage takes $27K of deposits to $13.34M of quoted depth.

The largest USDC/USDT pool on Solana holds $3.6M and pays 0.97% on the same 0.01% fee tier.

Stablecoin exposure only, no IL while both hold their peg➡️Provide Liquidity

Coffer holds Best Return on Sumex for USDT/USDC and cbBTC/zBTC 🏆

Tested both directions from $100 to $10,000. At $100 our route is 23 bps better than LI.FI protocol, and it stays ahead all the way up.

Two assets that track each other need almost no real TVL to hold a tight spread. That is where our leverage wins.

Swaps routed through us also compete for a $1,000 prize pool until Sep 15, 2 PM UTC➡1000$ Prize Pool

V5 of the smart contracts is live🗝

This update gives pool creators even more control over their positions:

🟡Sell-off window. A speed limit on how fast one token can be sold into a pool.
🟡Dynamic fee. A fee that rises as that window fills, charged in the token the seller walks away with.
🟡Switch off one token. Disable a bad asset without freezing the rest of the pool.
🟡Hard cap on the range manager. A floor and a ceiling on how far it can move a pool in one step.
🟡Single-token deposit. Bring one token, get a position in all 10.
🟡Set the range on a chart. Drag it, and the leverage updates on its own.

Read the full article to understand what each setting does and how to set it👉V5 UPDATE

Cube is now Coffer

As part of the Colosseum hackathon we rebuilt the full product and design. We also changed the name and moved to a new domain coffer.so.

Portfolio replaced Swap as the main page. The person we build for is an LP, so the app opens on what your capital did. Charts for net worth, PnL, impermanent loss against profit, and XP. Under that sit your token holdings and your open position pools.

Quick actions live on the same screen:
🟡Zap in puts your liquidity into an existing pool.
🟡Deploy new position creates a new pool with your own custom settings.
🟡Send position sends an LP position to another user, in whatever dollar amount you pick.

Recent activity now collects everything your wallet did in one place, across every pool, LP token and swap.

The Swap page is now called Trade. In the future, we are adding limit orders to it, so it will do more than spot swaps.

The pools page is now called Explore. It lists pools and their key metrics today, and the other DeFi instruments are going there in the future.

Why Coffer?
A coffer is a strong chest for keeping money and valuables safe, from the 13th-century Middle English cofre. A pool on our platform can hold up to 10 tokens at once, so the word fits the product better than a cube did.

The landing was rebuilt to match branding that stands on two pillars. Classical paintings, our nod to the past, which pairs well with the name Coffer. ASCII characters and layout, because underneath the paintings this is a program.

We keep working on all of it and ship something every day, so tell us what breaks. Come see the changes➡coffer.so

Eight months ago this was an empty repo ⬜

A read from Cube's founder on how it was born. The idea he could not put down, the nights he spent deriving the formulas by hand, the ten days in January that turned it into working contracts.

Cube reached $100K TVL and 2,000 on-chain users ⬜

More pools, more liquidity, more to come.

A meme token pool that keeps working beyond the hype ⬜

One of Cube’s live multi-token pools pairs a meme token with SOL, USDC and USDT.

Volume on any single token comes and goes. The liquidity underneath stays active either way.

When the meme goes quiet, its pairs go quiet with it. But SOL/USDC, SOL/USDT and USDC/USDT can keep trading, so the same LP position continues earning fees from that flow.

For traders, combining these assets in one pool means deeper liquidity and better execution.

This is just one use case for LMMM pools.
Is this how liquidity should work?
