Core Contracts

Summary

The RAACMinter contract assumes a fixed 12-second block time, which is inaccurate across different EVM-compatible chains. This incorrect assumption affects the calculation of emission rates, benchmarking, and other time-dependent operations, potentially causing unintended behavior on networks with different block times, particularly Layer 2 solutions.

Vulnerability Details

The protocol documentation states that the system is intended to be deployed on all EVM-compatible chains. However, the RAACMinter contract hardcodes a block time assumption of 12 seconds, leading to incorrect calculations in chains where the block time is different.

Affected Code in RAACMinter

Using a fixed block time of 12 seconds can lead to severe miscalculations on chains with different block speeds. For example, on Unichain (1s block time), the system would incorrectly assume 5x the number of blocks per day, distorting emission calculations.

Impact

Incorrect Emission Calculations: The number of blocks per day differs across chains, leading to over- or under-emission of RAAC tokens.

Use block.timestamp Instead of block numbers for time calculations
