Limits update 23/07/24: Polygon USDC pool deposit limits have been reduced from 10,000 to 1,000 per day after ongoing reviews of usage and demand.

View Transaction

• Daily user deposit limit set to 1000 USD

• Single deposit limit set to 1000 USD

• Daily user direct deposit capped at 1000 USD

• 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.

• Users with optional KYC through the Know your Cat protocol or businesses with inherent KYC can access higher limits through tiered limits.

• zkBob is multichain, with different limits for different tiers which can also vary by chain.

• Limits are reviewed periodically and adjusted as needed to maintain security and follow industry standards.
