## Complexity and Fragmentation

Most of the liquidity not on Ethereum in DeFi is spread across over 50 chains and hundreds of DEXs. As a result, DeFi remains fragmented, each with their own interfaces, DEXs, liquidity pools, unique features, and in some cases different wallet requirements. This creates a steep learning curve, especially for new users or those unfamiliar with multi-chain environments, resulting in a complicated and often frustrating user experience where it becomes difficult to both find the token you need or the DEX with the best price and liquidity.

## Slippage and Inefficient Liquidity

With liquidity scattered across chains, users can often encounter significant slippage, high transaction costs, and sub-optimal execution prices during swaps. Identifying the most efficient liquidity paths can be time-consuming and inefficient, further impacting trade outcomes.

## Poor User Experience

Many current DeFi platforms often fall short in delivering a seamless on or cross-chain experience, from unintuitive interfaces to linking users to upwards of 15-20 other protocol options to assist in their transactions, creating complex transaction flows, which leads to friction, frustration, and ultimately, abandonment of platforms.

## Gas Fee Optimization

Gas fees can start to become burdensome when conducting cross-chain transactions, or even when conducting multiple same-chain swaps, particularly when inefficient routing leads to suboptimal trade execution. This is a barrier to DeFi adoption, especially for users who frequently perform cross-chain activities.
