Introduction

Linea, a pioneer in the ZK space delivering a fully EVM-compatible, secure, and performant zkEVM rollup, is launching Linea Ignition campaign designed to boost liquidity depth, DeFi activity, and Linea’s long-term ecosystem growth. This incentive program is a catalyst for our ecosystem, targeting over $1 billion in TVL and distributing 1 billion LINEA tokens from the ecosystem fund managed by the Linea Consortium as rewards.

Linea Ignition campaign is supported by Brevis—a Infinite Compute Layer for Web3 (and Everything). Brevis unlocks a new level of scalability and trust for blockchain, by enabling blockchain applications to run complex, data-intensive computations off-chain while still proving the results on-chain using zero-knowledge proofs generated by Brevis Pico zkVM and zkCoprocessor.

Linea Ignition campaign exemplifies Continuous Protocol Incentivization — a new model allows protocols to distribute rewards sustainably over time based on on-chain behaviors. Brevis enables this process by generating ZK proofs for each LP’s activity (e.g. liquidity provided, volume absorbed), applying predefined reward logic, and enabling end-to-end on-chain verification of reward distribution. By launching the Linea Ignition campaign on Brevis, Linea is showing what it means to put principles into action:

• No centralized rewards database — every calculation is backed by a cryptographic proof published directly on-chain.
• No unnecessary friction — works seamlessly with positions users already hold.
• No compromise on trust — anyone can verify payouts independently.

All these actions make the Linea Ignition campaign fully secure, trustless, and transparent.

Rewards Calculation

Etherex Pools

Note: For Etherex pools, the displayed APR on the UI is just an estimate using last week rewards and current TVL. The actual APR of your LP position depends on the swap volume your liquidity absorbs and the corresponding swap slippage.

Rewards for each LP are allocated based on the swap volume generated by their liquidity and the slippage of each swap. The detailed reward formula is as follows.

For each pool and each epoch (1 epoch = 1 week), suppose there are $K$ swaps and $N$ LPs.

Then LP $i$’s reward for the pool and the epoch can be calculated as

$$ R_i=R_{total}\cdot\frac{\sum_{k=1}^KV_{(i,k)}F(\Delta P_k)}{\sum_{j=1}^N \sum_{k=1}^KV_{(j,k)}F(\Delta P_k)} $$

• $R_{total}$ is the total amount of LINEA rewards allocated to the pool during the epoch.
• $V_{(i,k)}$ is the volume absorbed by LP $i$ in swap $k$.
• $\Delta P_k$ is the actual slippage of swap $k$. For example, $\Delta P_k=0.003$ means that the execution of swap $k$ moves the price by 0.3% (either price up or price down).
• $F(\Delta P_k)=a\cdot(\Delta P_k)^b$ is a function of $\Delta P_k$ where parameter $a$ and $b$ are decided by the Linea team.

Note: Note: The reward reward formula and parameters might be updated on a weekly basis by the Linea team.

Lending Pools

Note: Looping or leveraged lending may be penalized. Please see reward details below.

For lending pools (Aave and Euler), the following reward calculation rules are applied.

Step 1: Compute Reward Allocation for Each Pool

For each epoch, there is a total reward amount $R_{total}$ for all the lending pools.

For each pool $k$, its weight $W_k$ during the epoch can be calculated as

$$ W_k=\beta_k Q_k *TVL^k_a $$

• $\beta_k$ is a per-pool constant (defined by the Linea team).
• $TVL^k_a$ is the actual effective TVL TWA (Time-Weighted Average) during the epoch in pool $k$.
• $TVL^k_t$ is the target TVL for pool $k$ (defined by the Linea team).
• $Q_k=Q_{min}+(Q_{max}-Q_{min}) \exp(-\alpha \frac{TVL^k_a}{TVL^k_t} )$, where $Q_{min}$ is the min ratio (e.g., 0.02) and $Q_{max}$ is the max ratio (e.g., 0.15). $\alpha >0$ is a sensitivity parameter (e.g., $\alpha=2$).

Then the reward allocated to pool $k$ during the epoch can be calculated as

$$ R_k = R_{total}*\frac{W_k}{\sum_{j} W_j} $$

Note: Each “pool” as mentioned above corresponds to an asset (e.g., USDC). If there are multiple lending protocols that support the same asset (e.g., Aave USDC and Euler USDC), the above formula can be used to calculate the reward allocation for each asset (where $TVL^k_a$ is the sum of actual TVLs from these protocols). Then the rewards are further split to different lending protocols proportional to their actual TVLs.

Step 2: Compute Each Users’ Rewards in a Lending Pool

For each pool $k$ and each epoch, the reward for LP $i$ can be calculated as

$$ R^k_{i}=R_k\cdot\frac{S^k_i}{\sum_{j=1}^N S^k_j} $$

• $R_k$ is the reward allocated to the pool (computed according to the formulas in Step 1).
• $S^k_i$ is the eligible holding by LP $i$ in pool $k$, calculated as $S_i^k = \max (0, c_i^k - \frac{d_i^k}{l_k})$, where
  • $c_i^k$ is the supplied collateral (aToken/eToken) TWA by LP $i$ in pool $k$
  • $d_i^k$ is the debt (dToken) TWA by LP $i$ in pool $k$
  • $l_k$ is the liquidation threshold for pool $k$ (e.g., 78% for Aave USDC/USDT pool, 83% for Aave ETH pool). For all Euler pools, the liquidation threshold is hardcoded to 92%.

Note: With the above formula of eligible holding, users who loop the collateral with the debt of the same asset will be penalized.

Note: Note: The reward reward formula and parameters might be updated on a weekly basis by the Linea team.

Campaign Information

Campaign Website

LPs can review the campaign information and view/claim their rewards directly through the campaign website: https://linea-ignition.brevis.network.

Rewards Update Epoch

Rewards are updated on a weekly basis. After each week ends, Brevis will retrospectively attest the rewards for all LPs for the past week. LPs should see their rewards for the past week updated on each Monday or Tuesday.

The start of each epoch (and the end of last epoch) is the UTC 00:00:00 every Monday.

Last Week Rewards

For Etherex pools: The “Last Week Rewards” displayed on the UI are the rewards allocated to the DEX pool during the past week.

For Aave and Euler pools: The “Last Week Rewards” displayed on the UI for each lending pool are the actual rewards allocated to the pool based on the calculated weights during the past week. View the rewards calculation rules for lending pools for details.

TVL

The displayed TVL of Etherex pools represents the total liquidity provided to this pool by all LPs, including both in-range and out-of-range liquidity.

The displayed TVL of Aave/Euler pools represents the total collateral value supplied to this pool by all LPs.

APR

The APR shown on the UI is an estimate value based on last week’s rewards and the current TVL, which is estimated as:

Note: For Etherex pools, the actual APR of your LP position depends on the swap volume your liquidity absorbs and the corresponding swap slippage.

End Date
