Incentive
An incentive is a payment, fee rule, discount, penalty, or token allocation designed to make a participant choose behavior the system needs.

System record
Start with the economic purpose, participants, resources, and entitlements before studying implementation detail.
Why it exists
DeFi protocols rely on external users to supply liquidity, liquidate unsafe debt, report data, validate state, vote, or secure networks, so desired actions need an economic motive.
Traditional-finance analogy
Performance compensation and market-making rebate is the closest comparison recorded for this concept.
Where the analogy stops
- Token issuance can fund rewards without current operating income, transferring value through dilution and market demand rather than cash earned by the protocol.
- Permissionless actors, composable positions, transferable rewards, and automated execution let participants optimize or game a rule faster than a managed compensation plan.
Main actors
- ActorReward payer or token issuer
- ActorLiquidity provider, lender, liquidator, reporter, validator, or voter
- ActorGovernance or parameter administrator
- ActorToken holder bearing dilution or treasury cost
Assets and claims
Assets — controlled or transformed resources
Assets are resources the mechanism moves, holds, values, or transforms.
- AssetFee revenue, reserve assets, or newly issued reward tokens
- AssetCapital or work supplied by the participant
Claims — entitlements and corresponding dependencies
Claims are rights to value, repayment, redemption, control, or another party's performance; each depends on an obligation or system that must honor it.
- ClaimAccrued or vesting reward entitlement
- ClaimEligibility right defined by the incentive rule
An incentive pays, rewards, discounts, or penalizes measurable behavior so that independent participants have a reason to perform a protocol function.
Why it exists
Section titled “Why it exists”Protocols need liquidity, lending capital, liquidators, data reporters, validators, voters, and other external actors. Code can define the action but cannot compel participation. An incentive connects useful behavior to an economic consequence.
Traditional-finance analogy
Section titled “Traditional-finance analogy”Performance compensation, a market-making rebate, or a service penalty is a useful analogy. The difference is that permissionless actors and composable contracts can optimize a rule at machine speed, while newly issued token rewards may be funded by dilution rather than operating income.
Actors, assets, and claims
Section titled “Actors, assets, and claims”The payer may be a trader, borrower, protocol treasury, or token issuer. The recipient may supply capital, execute liquidation, report data, validate state, or vote. Fee revenue and reserve assets are existing value; newly issued tokens are new units. An accrued or vesting reward is a claim only under the eligibility and distribution rules.
Mechanism and flows
Section titled “Mechanism and flows”- Define the target behavior and an observable measurement.
- Define payer, reward asset, rate, period, cap, and eligibility.
- Record eligible capital or work without double counting.
- Accrue and distribute or vest rewards under explicit claim rules.
- Measure whether the behavior persists and whether adversaries can game the proxy instead of producing the intended outcome.
Capital flow includes participant capital and paid rewards. Claim flow covers accrued rewards. Return flow names the payer: users and protocol revenue pay fees, a treasury spends reserves, or token holders bear dilution. Control flow follows whoever changes weights and eligibility. Risk flow includes sybil behavior, wash activity, bribes, mercenary capital, and reflexive token prices.
State and loss allocation
Section titled “State and loss allocation”| Funding source | Recipient return | Economic cost bearer |
|---|---|---|
| User fee | Existing asset revenue | User paying for service |
| Borrower interest | Interest income | Borrower |
| Treasury subsidy | Reserve distribution | Treasury stakeholders |
| New token issuance | Reward tokens | Existing and future token holders through dilution |
| Penalty or slashing | Transfer or burn | Penalized participant |
If subsidy attracts capital that leaves immediately, the treasury or token holders pay without buying durable service. If the rule is gameable, honest users can face worse liquidity, governance, security, or reward allocation.
Beginner lens
Section titled “Beginner lens”Always ask who pays a reward. “Free tokens” can be a temporary subsidy whose market value and dilution change after the campaign ends.
Practitioner lens
Section titled “Practitioner lens”Measure retained liquidity or service after subsidy, marginal cost per desired outcome, emissions versus fees, vesting, caps, recipient concentration, sybil resistance, bribes, wash activity, exit behavior, and governance control over weights.
Engineer or auditor lens
Section titled “Engineer or auditor lens”Curve DAO gauges are one implementation in which protocol issuance is allocated according to gauge weights and eligible liquidity. That design illustrates the need to audit checkpointing, measurement periods, voting influence, boost rules, claim accounting, and emission caps; it is not a generic reward formula.
Security review notes
Section titled “Security review notes”Bind reward state to one eligible identity, amount, period, and funding source. Test duplicate claims, boundary timestamps, stale checkpoints, self-dealing, sybil splitting, flash capital, ordering, rounding, cap exhaustion, governance changes, and zero-value activity.
Common misunderstandings
Section titled “Common misunderstandings”- “High APY proves high productive return.” Issuance and subsidy can dominate fees or external income.
- “More deposits mean the incentive worked.” Capital can be temporary or economically unproductive.
- “Users follow the intended behavior.” Rational actors optimize the encoded measurement, including its loopholes.
Prerequisites and learn next
Section titled “Prerequisites and learn next”Read tokenomics. Continue to protocol treasury to identify whether rewards spend reserves or issue new units.

Machine-readable model
Key equations
Canonical expressions come from the structured concept record. KaTeX renders the notation, while the plain-text expression and variable table keep its meaning and units inspectable without JavaScript. Read the narrative above for the model's domain, assumptions, and rounding rules.
This concept does not require one canonical equation. Its mechanism and state transitions remain the authoritative explanation; do not invent a formula merely to make the topic look quantitative.
Assurance contract
Security properties
These structured statements define desired behavior. Their stable IDs can bind tests, invariants, specifications, audit findings, or proof results without turning descriptive review advice into an assurance claim.
Desired · not evaluated: No test, audit, or proof result is implied until scoped evidence is linked to this property.
Reward eligibility, measurement period, units, funding source, caps, vesting, and claim lifecycle are explicit
One unit of eligible work or capital cannot be counted repeatedly outside the documented rule
Adversarial splitting, self-dealing, ordering, and sybil behavior cannot extract rewards beyond the threat model
Reported return separates fees or external income from token issuance, dilution, and temporary subsidy

Who pays a newly issued token reward?
Model answer
No existing asset necessarily leaves a payer's account, but current and future holders bear dilution and depend on market demand for the new units.
