In https://github.com/rotki/rotki/pull/5207/files#diff-93dd3d2fccb5ce3e2b0a394be8aa37f0c27f48d449b1c61182f07011c0318472L180 we removed the code using the subgraph to query for LP positions in uniswap, sushiswap and balancer. We need a new way of detecting the LP positions and adding them to the balances.

Approach proposed

We can use the decoded transactions to detect the pools where the user has deposited assets. We can solve the problem in two ways

• A better approach will be replaying the history and knowing exactly the LPs with non 0 value for each address
• The second approach is to query the deposits in uniswap pools and query balances for all the possible tokens for each address

Requirements

For this approach we need to add decoders for deposits/withdrawals of LP positions. For Uniswap we don't have them at the moment and for balancer #5197 does it
