BOB is currently available on Polygon, Optimism, Arbitrum, BNB Chain and Ethereum. BOB can be acquired in several ways outside of the zkBob application.
- Sent between users to any 0x address on Polygon, Optimism, Arbitrum, BNB or Ethereum.
BOB token inventory is pre-minted and paired with an existing stable token (multi-collateral, for example USDC and BUSD) on decentralized exchanges featuring concentrated liquidity mechanisms (Uniswap v3, Kyberswap). The ability to set a narrow exchange rate range via ticks and provide concentrated liquidity for the pair results in very limited slippage to the stablecoin peg. Learn More.
Called an inventory LP position, this mechanism maintains BOB stability while providing the option for users to purchase BOB inventory.
To enter the circulating supply, BOB must be purchased from the inventory. Users can then create their own LP positions from this purchased BOB, resulting in additional non-inventory LP positions (BOB/WETH, BOB/GNO etc) within the ecosystem.

BOB inventory is increased in LP positions currently via a small governance multisig Safe. The goal is to balance inventory supply with demand and usage. Inventory details are described and catalogued here. A larger DAO formation is in the early stages to govern BOB minting, upgradeability and other critical operations moving forward.
No, not through the protocol itself. BOB stablecoin is designed for utility and low fees. The protocol is able to collect revenue through fee collection and idle-capital compounding. These fees can then create a self-sustaining protocol which subsidizes low cost transactions for users. BOB holders can earn fees in other ways such as providing liquidity to non-inventory LP positions on DEXs like Uniswap, Quickswap and Kyberswap.
Overarching BOB governance (including BOB inventory, CDP settings and zkBob updates) are currenlty handled via a governance multi-sig SAFE. This process will be transitioned to a larger BOB DAO following the beta implementation. Information about BOB governance, proposals and decisions is located here.
