## SSTORE Gas Refund Limits

SSTORE gas refund limits are the maximum amounts of gas that can be reclaimed by a user through state-cleaning operations in a single transaction. These limits are set by the protocol to prevent abuse and ensure that the refund mechanism does not negatively impact the stability of the network.

Without these limits, it might be possible for malicious actors to create transactions that are extremely cheap to execute while still consuming significant network resources. The limits are periodically adjusted based on network usage and security analysis.

They represent a compromise between incentivizing state cleanup and maintaining network safety. Understanding these limits is important for developers when designing contracts that rely on refunds.
