Sherpa
Introducing the unique algorithm Sherpa designed by EISEN Finance to minimize the slippage.
Swaps using the Sherpa
EISEN Finance uses its swap algorithm, Sherpa, to find the optimal swap path for every new block, enabling swaps with reduced price impact and slippage.
Similar to Himalayan Sherpas guiding climbers safely and efficiently, EISEN Finance's swap service uses the 'Sherpa' engine to navigate users through the crypto space, ensuring they attain the optimal swap ratio. Presently, EISEN Finance's swap service is accessible on EVM-compatible mainnets.
Price impact
Automated Market Makers (AMMs) make swap rates vary with the amount being swapped. Price impact is the difference between the swap rate for a small selling amount and the swap rate for the actual selling amount.
Slippage
DEXs utilizing AMMs provide only market orders, leading to variations in swap results for transactions involving the same pools on the blockchain. Slippage is the discrepancy between the expected and actual amounts
Merge Swap Routing
Sherpa leverages the composability of DeFi to access all available liquidity sources on the chain, as most DeFi liquidity pools are permissionless. When accessing liquidity sources, there are five methods for routing sell tokens, as described below. EISEN uses the most advanced approach, merge swap routing, which allows it to provide traders with better swap prices than other protocols using simpler algorithms.
Multi-hop swap refers to the process of finding the optimal swap path where the entirety of sell tokens only pass through multiple DEXs, without being split.
Reduced Price Impact
By splitting the sell amount into multiple DEXs, Sherpa can reduce the price impact.
See the paths colored in red below.
100A in DEX 1 (single DEX) takes up a greater proportion than 40A in DEX 1 (DEX aggregator).
This is why the price impact is lower when using a DEX aggregator than a single DEX.
Reduced Slippage
By capturing potentially profitable arbitrage opportunities that arise when traders swap their assets and return a portion of the profits to traders, Sherpa offsets traders' losses from slippage.
To explain further, whenever a trader swaps asset ETH for USDC, the front-running transaction that also swaps ETH for USDC will drive up the price of USDC and cause slippage for the trader.
Sherpa therefore examines whether the cyclic arbitrage path USDT -> USDC -> ETH -> USDT can generate a profit, given that the price of USDC has increased.
If the arbitrage is deemed profitable, Sherpa executes it and returns a portion of the profits to traders.
Asset USDT is sourced from EISEN's own vault (for EVM-incompatible chains) or through a flashloan (for EVM-compatible chains).
