Due to Arbitrum Sequencer, rappers can be stronger than expected with less training
Description
On Arbitrum, a sequencer is used for block.timestamp, and it can deviate by up to 24 hours earlier or 1 hour in the future compared to real-time (See Arbitrum docs for more information).
A rapper is supposed to wait at least 1 day during staking to be more confident. However, if block.timestamp is 24 hours earlier (due to Arbitrum sequencer) during a call to stake, a rapper will directly have weekKnees = true if he/she is unstaked. It will save one day for the rapper to be stronger.
Risk
Likelyhood: Low
Depends of the Arbitrum Sequencer.
Impact: Medium
Rappers will save one day of training in the street.
Recommended Mitigation
Use an oracle like Chainlink to have accurate data for the time.
Alternatively, consider using other Ethereum Layer 2 solutions or the Ethereum mainnet to avoid issues related to time deviation.
