Read historical supply and NAV/share for Wren Staked tGBP.

class WSTGBPVaultHistoricalReader

Bases: eth_defi.vault.base.VaultHistoricalReader

Read historical supply and NAV/share for Wren Staked tGBP.

wstGBP does not implement ERC-4626 convertToAssets() or totalAssets(). Its canonical onchain share price is navprice(). Historical TVL is therefore totalSupply() * navprice() in the ERC-20 denomination returned by gem().
