Limits are imposed to protect against large deposits and withdrawals which may result from illegal activity (for example a hack where attackers need to quickly move a large amount of funds).
By default, new users are limited in the amount they can deposit and withdraw.
zkBob is multichain, with different limits for different tiers which can also vary by chain.
There are 2 pools for Optimism, one for USDC and a second for ETH.
Limits are reviewed periodically and adjusted as needed to maintain security and follow industry standards.
