# Assets

We store user positions as Assets which store their original liquidity balance, the liquidity type, and node information for each node they use in AssetNode. We essentially keep track of an Assets fees and liquidity balance by tracking them separately for each node they use in the tree.

These AssetNodes are updated during WalkerLib.modify.
