Withdrawals can take about 3 hours to complete.
Remember that Aevo is an Ethereum rollup and like all L2 needs a reasonable amount of time before transferring transactions to the mainnet, in order to safeguard the security and finality of transactions.
In other words, the 3 hours are necessary for your safety!
In addition, Aevo constantly and randomly selects some withdrawals for additional security checks. If your withdrawal is selected, it will be completed within 12 hours. Please bear with us: this is an additional security measure, necessary to ensure that the exchange works properly!
