Asset valuations applicable to tax
When the need arises to work out the value of boxETH, there is a simple solution to pulling the necessary information for your jurisdictions tax requirements.
Assuming you’ve only traded it using the boxETH/stETH LP or resolved part of another user's debt position (which is a trade from boxETH to stETH), then you can derive the value of boxETH directly from the value of stETH at the time of the trade.
