# A constant used in `_can_deposit_or_withdraw` when comparing Lido share prices.
#
# Due to integer rounding, Lido.getPooledEthByShares(10**18) may return slightly
# different numbers even if there were no oracle reports between two calls. This
# might happen if someone submits ETH before the second call. It can be mathematically
# proven that this difference won't be more than 10 wei given that Lido holds at least
# 0.1 ETH and the share price is of the same order of magnitude as the amount of ETH
# held. Both of these conditions are true if Lido operates normally—and if it doesn't,
# it's desirable for AnchorVault operations to be suspended. See:

    # The code below sells all rewards accrued by stETH held in the vault to UST
    # and forwards the outcome to the rewards distributor contract in Terra.
    #
    # To calculate the amount of rewards, we need to take the amount of stETH shares
    # the vault holds and determine how these shares' price increased since the last
    # rewards sell operation. We know that each shares that was transferred to the
    # vault since then was worth the same amount of stETH because the vault reverts
    # any deposits and withdrawals if the current share price is different from the
    # one actual at the last rewards sell time (see `can_deposit_or_withdraw` fn).
    #
    # When calculating the difference in share price, we need to account for possible
    # insurance applications that might have occured since the last rewards sell operation.
    # Insurance is applied by burning stETH shares, and the resulting price increase of
    # a single share shouldn't be considered as rewards and should recover bETH/stETH
    # peg instead:
    #
    # rewards = vault_shares_bal * (new_share_price - prev_share_price)
