What happens if an attacker uses an abnormally high gas fee?

If an attacker uses an abnormally high gas fee, FailSafe Interceptor handles the situation through several strategic measures:

• Enterprise-Defined Gas Fee Threshold: Enterprises can set a maximum gas fee they are willing to pay to protect their funds. This allows for a controlled and predictable response to high gas fee attacks, ensuring cost-effective protection.

• Obfuscated Recovery Vault: The Recovery Vault is only deployed in the block where the attack is occurring, making it invisible to attackers until it is actively protecting assets. This obfuscation prevents attackers from knowing whether an enterprise is protected by FailSafe, reducing the likelihood of preemptive gas fee escalation.

• Risk of Gas Fee Forfeiture for Attackers: Since attackers are unaware of FailSafe's protection, any preemptive action to increase gas fees can backfire. If FailSafe successfully intercepts the attack, the attacker's transaction, whether it succeeds or fails, incurs computational costs. Validators must verify and execute the transaction, which consumes computational power, leading to the attacker forfeiting the gas fees paid for the failed transaction.
