How long does a Hop transfer take?

It depends which network you are sending to and from. As a general rule of thumb, L1 to L2 transfers take the same amount of time than sending via the native bridge. For example, depositing from Ethereum to Polygon takes 8 minutes via the Polygon bridge and the same amount of time with the Hop bridge. This is because Hop itself uses the native bridges for L1 -> L2 deposits. The advantages with Hop come about when you transfer the other way around from L2 to L1 or from one L2 to another L2. Here, the rule of thumb is that an exit will take as many blocks to be considered final (safe from reorgs) on the sending chain. Deposits from L1 Ethereum -> Gnosis Chain: ∼5 minutes Ethereum -> Optimism ∼10 minutes Ethereum -> Arbitrum ∼16 minutes

Ethereum -> Polygon: ∼18 minutes

Withdrawals Arbitrum

Arbitrum -> Ethereum: ∼1 min Arbitrum -> Any other L2: ∼1min

Withdrawals Optimism

Optimism -> Ethereum: ∼1 min Optimism -> Any other L2: ∼1min

Withdrawals from Gnosis chain

Gnosis chain -> Ethereum: ∼1 minutes Gnosis chain -> Any other L2: ∼1min Withdrawals from Polygon Polygon-> Ethereum: ∼4.5 minutes Polygon-> Any L2 : ∼4.5 minutes
