Crema Finance

Inspiration

Inspired by Uniswap V3's price band liquidity provision, we are excited to build this concentrated liquidity market maker (CLMM) infrastructure on Solana.

What it does

Our CLMM allows liquidity providers to specify their price ranges when they add their liquidity. The capital efficiency can be dramatically improved and users can conduct range order trading with CLMM.

How we built it

Crema Finance's CLMM algorithm is fully developed in the native Rust language.

Challenges we ran into

Solana's strict computational limit is challenging to any CLMM builders because the algorithm complexity is way higher than that of the common AMM model.

Accomplishments that we're proud of

We are proud that we have successfully launched the first concentrated liquidity market maker (CLMM) on Solana mainnet.

What's next for Crema Finance

There will be a series of big moves and great news of Crema in the next few months. Our NFT liquidity farming function is about to be launched very soon, which will give our liquidity providers great extra incentives. We are also going to be explore our multichain versions to other ecosystems such as Terra and support the cross-chain swap between Solana and other networks. With our CLMM pools to be deployed on multichains, the price slippage during the cross-chain swap can be controlled to the minimum level.

The values that our CLMM can add to the cross-chain market

High price slippage and inadequate liquidity are the most typical painpoints that current cross-chain swap solutions are struggling with. The situation is even worse when it comes to those non-mainstream tokens. The altcoins pool liquidity in cross-chain contracts is usually very limited and AMM trading pool price will also suffer from a high price impact when there is a large-size swap order. These issues leave the current cross-chain swap solutions far from reaching the point of ubiquity. Now, we want to change this. With our CLMM trading pools and smart router system to be deployed on multiple blockchain networks, we can ensure that the price slippage on both sides during the cross-chain swap can be controlled to the lowest level. At the meanwhile, we plan to integrate with existing influential cross-chain bridge such as Wormhole to bridge the gap and introduce UST stablecoins and its wrapped version at the medium to set up the trading route between two ecosystems, which can effectively avoid the lack of liquidity. In the end, Crema are wishing to serve as a fundamental element of the next-gen cross-chain solutions that can give all users barrier-free trading experience.
