What are liquidity mining incentives and how long do they last

02 September 2026

Liquidity mining incentives are token rewards given to users who deposit assets into a protocol’s liquidity pools. They are a marketing tool disguised as yield. The core idea is simple: instead of paying for user acquisition with cash, a project pays with its own newly created tokens.

These incentives are separate from the underlying revenue a protocol earns. A liquidity pool that charges trading fees, for example, collects those fees regardless of whether mining incentives are active. The interest or yield you see quoted in an APY often combines two very different streams: real fees and subsidized tokens. The subsidized part can disappear overnight.

How they work

A protocol prints its own governance or utility token - think COMP for Compound, CRV for Curve, or any of the hundreds of variants. It then allocates some of those tokens to specific pools. Users who deposit into those pools earn a pro-rata share of the daily emission. The more value locked in a given pool, the smaller each individual’s share becomes.

Compound’s COMP distribution is the canonical example. From mid-2020, Compound began distributing COMP to users who supplied or borrowed assets on the protocol. The emission schedule was fixed: a known number of tokens per day, halved over time according to a pre-set rate. Users could calculate exactly how many COMP would be issued on any given day, and therefore the approximate dilution rate for existing holders.

Curve uses a different twist. Its liquidity pools compete for CRV emissions via “gauge weights.” A pool’s weight determines what percentage of the day’s CRV emission it receives. The weights can change weekly based on governance votes. A pool with heavy voting support might earn 10% of daily emissions one week, then drop to 2% the next. The yield is therefore not predictable over longer periods.

How long do they last

That depends entirely on the tokenomics of the specific project. A few general categories exist.

Fixed emission schedules. Some protocols commit to a set number of tokens per day or per block, with a known end date or a halving schedule. You can check the relevant block explorer or the protocol’s documentation to find the emission rate. The schedule is usually hardcoded into a smart contract. You can verify it yourself if you know how to read a Solidity source file or use a block explorer’s read functions.

Gauge-based or voting-dependent. Curve falls here. Emissions continue as long as there is a token supply to allocate. The protocol may have an infinite emission schedule with gradual decay, or it may allocate a fixed percentage of inflation each year. The real end date matters less than the fact that yields can plummet within a week when gauge weights shift.

Community-governed. The protocol may hold periodic votes to adjust emission rates. This is common with DAO-run projects. The next vote could cut emissions to zero, or extend them indefinitely. There is no guarantee.

How to check an emission schedule yourself

You need three pieces of information.

1. The token’s total supply and emission schedule. This is often published in the protocol’s documentation. Look for a section on “tokenomics” or “emission schedule.” For more trustworthy projects, the schedule is encoded in a smart contract on the blockchain. You can verify it using a block explorer.

2. The current allocation to the specific pool you care about. For fixed-schedule protocols, this is the emission per block multiplied by the pool’s fraction. For gauge-weighted protocols, you need the pool’s current weight. Curve publishes gauge weights on its website. Compound publishes distribution schedules per asset.

3. The dilution rate. This is the percentage of the total token supply being emitted per year. A protocol that issues 10% of its total supply annually is diluting existing holders by 10% per year. If the token price stays the same, holders of the token lose 10% of their purchasing power annually to inflation.

When incentives wind down

The most common sign is a reduction in daily emissions without a corresponding increase in protocol revenue. You can observe this on the protocol’s dashboard. If farming yields decline month-over-month while trading volumes stay flat, the mining incentive is shrinking.

Another sign is when the protocol’s own token price falls while its supply inflates. The yield you earn is denominated in that token. If the token price halves, the USD value of your rewards halves, even if the token count stays the same.

A third sign is governance proposals to redirect emissions elsewhere. If the community votes to transfer emissions from pool A to pool B, the existing pool’s yield will collapse. You should monitor governance forums for such proposals.

The bottom line

High APY on a liquidity mining program is a temporary subsidy. It is not revenue. Treat it as a marketing budget that will eventually run out. The question is not whether it ends, but when. If you cannot find the emission schedule or verify the tokenomics, assume the yield will last only a few weeks. That is usually the safest bet.
