Participating in a testnet, like zkSync Lite, does not automatically guarantee mainnet rewards. However, it is a strong positive signal. Projects often use testnet activity to identify early, technically-inclined adopters who are willing to help stress the network without financial incentive. While not a direct 1:1 guarantee, this demonstrated support is frequently rewarded in retrospective airdrops. Many major protocols have allocated tokens to active testnet users, making it a high-value, low-cost strategy to potentially qualify for a future mainnet distribution.

For a risk-averse operator, break-even is not a simple financial equilibrium but a utility-based one, where the expected utility of staking equals the utility of a risk-free alternative. This requires a multiplier that provides a significant risk premium above the mathematical expected loss. The calculation uses a utility function, such as the Constant Absolute Risk Aversion (CARA) model: U(W) = -exp(-γ * W), where γ is the risk aversion coefficient. The operator compares the utility of their current wealth to the expected utility of staking, which is a weighted average of utility after receiving rewards and utility after being slashed. Solving for the reward that makes the expected utility of staking equal to the utility of not staking yields the break-even multiplier. This value is always higher than the risk-neutral break-even point and increases with both the slashing probability and the operator's personal level of risk aversion (γ). It compensates for the psychological cost of bearing uncertainty.
