What is a Gauge?
How it works
Gauges were pioneered by Curve Finance. A liquidity provider deposits LP tokens into a pool's gauge contract, which tracks each depositor's share over time. A separate GaugeController contract holds a weight for every gauge, and the protocol's fixed token emission (CRV on Curve) is split across gauges in proportion to those weights. Your reward rate is therefore your share of the gauge multiplied by the gauge's share of emissions.
Weights are not set by the team — they are voted on by holders of the vote-escrowed governance token (veCRV), created by locking CRV for up to four years. Each address can update its vote per gauge every ten days, and weights recompute weekly. Curve adds a boost mechanic: a depositor holding enough veCRV earns up to 2.5x the base reward rate on their own gauge positions, tying emissions capture to long-term lockers.
Because gauge weight converts directly into token emissions, a market formed around it. Protocols pay veToken voters "vote incentives" (bribes) through platforms like Votium to point emissions at their pools, and meta-protocols such as Convex accumulated veCRV at scale so that much of the vote flows through their wrappers. Balancer (veBAL), Frax, and ve(3,3) DEXs like Velodrome adopted the same architecture, making gauges a standard DeFi primitive.
Why it matters
Gauges turn token emissions — usually a protocol's single largest expense — into a transparent, governed resource instead of a fixed schedule. Incentives can follow demand: a new stablecoin pool wins emissions by convincing lockers, not by lobbying a core team. Gauges also produced DeFi's clearest demonstration that governance power has cash value: the "Curve Wars," in which protocols spent heavily accumulating CRV and CVX purely to control gauge weights. For users, gauge mechanics explain why two similar pools pay very different APRs and why headline yields depend on boost. For analysts, gauge votes are a leading indicator of where liquidity will move — and a persistent attack surface, since anyone who amasses enough voting power can aim emissions at a worthless pool.
Real-world examples
In November 2021, Mochi Inu gamed Curve's gauge system. It paid vote incentives to direct CRV emissions toward its USDM stablecoin pool, attracting deep liquidity, then minted large amounts of thinly backed USDM and swapped roughly $46 million of it for DAI, draining the pool — using part of the proceeds to buy CVX and reinforce its gauge vote. Curve's Emergency DAO killed the gauge within days, a landmark case showing both the cash value of gauge weight and why gauge governance needs guardrails.
FAQ
Is depositing into a gauge the same as staking?
It is a form of staking — you stake LP tokens into the gauge to earn emissions — but a gauge adds a governance layer on top. How much the gauge pays out is decided by token-holder votes rather than fixed in code, and on Curve your personal rate can be boosted up to 2.5x by also holding veCRV.
What are gauge 'bribes'?
Payments — more neutrally, vote incentives — that a protocol offers to veToken holders who vote emissions toward its gauge, typically via marketplaces like Votium. For the paying protocol this is often cheaper than funding its own liquidity mining program, because it rents the host protocol's emissions instead.
Do gauges exist outside Curve?
Yes. Balancer uses gauge voting with veBAL, Frax runs gauges for its pools, and ve(3,3) DEXs such as Velodrome and Aerodrome made weekly gauge voting the core of their design. The pattern — governance-weighted emission routing — is now a standard DeFi primitive.
