BOB Stablecoin

BOB is an innovative, multi-chain and multi-collateral stablecoin optimized for reliable value transfer. On its own, BOB is perfectly suited for everyday usage.

Unlock BOB's
privacy power

Using BOB with zkBob enables optional and robust privacy features.
With zkBob, BOB holders, senders, and receivers gain access to a secure platform featuring advanced zk functionality.
zkBob + BOB stablecoin transfers are safe, secure, cataloged, and completely confidential.
Transfers are wholly contained within the application. Users do not need a 3rd party wallet like MetaMask or any tokens other than BOB to transfer and withdraw.

100% on-chain

Inventory is managed and stored transparently on-chain.
Stability is balanced on-chain via concentrated liquidity AMM algorithms.
BOB is acquired on-chain at a ~1:1 ratio to stablecoins such as USDC and BUSD.

BOB is currently available on Polygon, Ethereum, BNB Chain, and Optimism.
