Employee Salary

Businesses often prefer to keep salary information private. This creates issues for some businesses who want to use blockchain for payments but also want to keep salary information confidential. With zkBob, employers can keep information private and use the blockchain to send salaries.

Several prominent projects in the ecosystem are already using zkBob for salary payments. These Tier 1 projects are able to deposit higher amounts into the protocol for sending salary to known employees of the business. Since employees are KYC'd by their employers, this KYC is automatically inherited into the protocol.

Multi-sender functionality and integrations with projects like Request Finance make salary processing even easier as more users onboard to zkBob.

Generic Use Case: Bob 👨‍💼 the Business Employer

Bob has 5 employees (Alice, Carlos, Dave, Erin and Frank) he pays monthly with crypto. Bob’s preference is to keep salaries private while still processing them on-chain and using a stable asset for payment. zkBob makes it easy.

  1. Bob and his employees each create their own zkBob zkAccounts, using either a secret phrase or web3 wallet private key.

  2. Bob deposits USDC or BOB into the zkBob application (depending on his pool selection).

  3. Alice, Carlos, Dave, Erin and Frank each send Bob their zkAddress in a private DM on Slack.

  4. Bob transfers USDC or BOB to each employee for their monthly salary.

  5. Once received (or at a later time to improve anonymity) Alice, Carlos, Dave, Erin and Frank choose to withdraw any amount of USDC into a 0x wallet on Polygon. This can be a brand new address (which is also sent 0.1 MATIC for txs) or an established 0x address.

  6. Alice, Carlos, Dave, Erin and Frank can convert their BOB or USDC to a coin/token of their choice, and use however they wish (ie send to an exchange, bank, pay with crypto etc).

  7. The history tab within each zkBob account makes it easy for employees to track and report their own transfers and withdrawals.

  8. The process is repeated monthly, with employees DM’ing Bob a newly generated zkAddress at the beginning of each month.
