Why does a withdrawal take 7 days?

This guide provides information on the time it takes to process a withdrawal from Metal L2.
 

When transferring assets from Metal L2 to Ethereum L1, please note that it takes 7 days due to a security feature called the Challenge Period. This waiting period is designed to ensure the safety of the Metal L2 Bridge and to mitigate any potential vulnerabilities, as explained by the Optimism L2 protocol.
