YB token
YB is the ERC-20 governance token of YieldBasis. To vote on proposals and gauges, or to earn a fee revenue share, you lock YB into veYB, a vote-escrowed position. Unlocked YB has no protocol utility.

Supply structure
The maximum supply of 1,000,000,000 YB has two parts:
- Pre-allocations: 700,000,000 YB. The owner minted them with
mint()to vesting contracts (team, investors, treasury, and others) before it renounced ownership. For the distribution and the vesting schedules, read Tokenomics. - Emission reserve: 300,000,000 YB.
GaugeControllerreleases the reserve over time withemit(), on an exponential-decay schedule. Thereservestate variable holds the remaining YB thatemit()can mint. It approaches zero but does not reach it. For the math of the decay curve, read Emission dynamics.
reserve + totalSupply equals 1,000,000,000.
Nobody can add a new minter, because the token has no owner. renounce_ownership() removed the owner and its minter role, and owner() returns the zero address. The GaugeController holds the minter role and mints only through emit(), which is bound by the reserve. Verify the full minter set from the token's RoleMinterChanged events.
Utility when locked
Lock YB into veYB to get three rights:
- Votes on YB DAO proposals.
- Gauge votes, which direct YB emissions across markets.
- A fee revenue share, paid in yb-LP tokens (the share tokens of YieldBasis markets), on the terms in veYB.
