My imported Polygon transactions for Balancer shows a balance mismatch for following:
B-50WBTC-50WETH: 38.2323171
B-POLYBASE: -38.2323171
I filtered the Koinly transactions for B-50WBTC-50WETH, copied one of the transaction hash and looked it up on Polygonscan, and Tokens Transferred shows B-POLYBASE. There’s no mention of B-50WBTC-50WETH on Polygonscan. If the B-50WBTC-50WETH transactions were updated with B-POLYBASE then the issue will be resolved but there could be new transactions that get imported as B-50WBTC-50WETH in the future.
This is the token address for this Balancer pool: Balancer Polygon Base Pool (B-POLYBASE) Token Tracker | PolygonScan
