    zkBob

    BOB is a multi-chain, multi-collateral stablecoin. When paired with zkBob, BOB can be transferred completely privately using advanced zk cryptography, without the need for 3rd party wallets like Metamask. Limits and compliance integrations make this a safe option for users who want honest privacy for ordinary use cases (remittance, salary, P2P, donations etc).
