Pickle Finance is a yield aggregator that compounds LPs across various chains:

There are a constantly evolving series of opportunities for yield farming across the DeFi ecosystem. Pickle Finance provides a tailored selection of Pickle Jars and Pickle Farms that have been custom-built to earn yield from specific assets and through specific DeFi protocols. Jars are the Pickle equivalent of yearn.finance’s vaults. A jar receives a specific asset (usually an LP token), such as sLP ALCX/ETH (Liquidity provider token for the ALCX/ETH pair on SushiSwap) and utilizes a strategy developed by the Pickle Finance team to earn yield on that asset. Your asset will auto-compound to earn more of itself, meaning your holdings of that asset will only increase. However, jars don’t prevent your asset from losing value relative to USD.

Farms are the “next step” after putting an asset into a jar. When you deposit an asset into a jar, such as sLP ALCX/ETH, you will receive a number of pTokens (in this example, pSLP ALCX/ETH) that represent your share of the tokens in the Jar. These pTokens can then be staked in the appropriate farm to earn additional PICKLE rewards on top of your existing rewards. Your PICKLE rewards can be boosted by locking existing PICKLE tokens for DILL for up to four years.
