Politically exposed individuals or associates of those individuals are not permitted to use the application under existing laws.
Prior to using zkBob, a user must acknowledge and accept the following terms:
  • If acting as an individual you are of legal age (as applicable in the jurisdiction where you live).
  • You are not a politically exposed person, that is, a person who is entrusted with any prominent public function, or a politically exposed person who has stepped down from that role.
  • You are not an immediate family member or close associate of a politically exposed person or a politically exposed person who has stepped down.
  • You are not engaged in money laundering or the financing of terrorism.

  • You have not been arrested or convicted of any offence or crime.
  • You are willing to provide and verify your identity upon request.

User Responsibility

  • Use of zkBob is at the sole risk of the user.
  • The code repository, decentralized and autonomous protocol and environment, and associated decentralized networks are open-source and not controlled by any team.
  • zkBob contributors are not responsible for any losses or damages associated with inherent risks associated with cryptography, blockchain, or digital wallet usage.
  • The user agrees not to access zkBob using any technology for the purposes of circumventing location-based restrictions.
  • Users are responsible for reporting and paying any applicable taxes associated with usage.
  • Users acknowledge that addresses may be blocked from using the protocol if they are sanctioned or added to a block list.

Daily limits

Limits are imposed to prevent large-scale transactions which may be the result of illicit activity. Deposit limits are detailed here.

Geo Restrictions

The zkBob application is in Beta with minimal restrictions enabled. Users must abide by local, state and federal laws. Please check prior to usage.
Users in the UAE are programmatically restricted from using zkBob due to Virtual Assets Regulatory Authority (VARA) policies which prohibit anonymity-enhanced transactions. These policies are available here.
The BOB stablecoin on its own is not an anonymity-enhanced cryptocurrency, however when used with zkBob privacy is enabled. Therefore, out of an abundance of caution and necessity to preserve safe transactions for all zkBob users, UAE users are prohibited from accessing the protocol.
Post-beta, restrictions may be enabled for additional countries based on legal considerations.

Wallet Compliance

An integration with TRM and potential future integrations with VAF Compliance and PureFi ensure 0x wallets interacting with the protocol do not contain funds obtained from illicit sources. Suspicious wallets cannot deposit into the protocol, and funds cannont be withdrawn to suspicious wallets.

Security

Beta Release

zkBob is now released in a beta version. Contracts have been audited, and users should use at their own discretion. Risks to users are mitigated through limits on deposits and withdrawals. In addition, the overall size of a pool cannot exceed 1,000,000 BOB tokens.

Bug Bounty

Bounties are one of the most important tools for testing and enhancing application and contract security. We are in the planning phases to implement a bug bounty to help protect users and their funds.
