In this dashboard, Deposit Volume to Optimism in native bridge and HOP bridge are analyzed.

Methods

• Using contracts of the native bridge to identify eth transfers in ethereum.core.ez_eth_transfers table
• Using contract, Event name and event input of HOP protocol transactions in ethereum.core.fact_event_logs table to identify deposit transactions
• For withdraw via HOP, I actually did transactions on HOP but I couldn't find any event that relate the transaction to any L2 blockchain. so in this dashboard only deposit transactions are compared.

Let's look at statistics of deposit transactions via OP native and HOP bridge:

• Deposits from ETH to OP via native bridge is way more popular than HOP. It could be because the fee doesn't differ much.
• Based on my previous dashboard, the withdraw via native bridge is not popular (less than 10 transaction per day) because it take 7 days for the transaction to complete, So I think withdraws are done using a third party brides as native withdraw page of OP recommend it because of the time it takes.
• the volume of withdraws from native bridges is also high ( based on OPTIMISM BRIDGE - Wallets dashboard: More than 32 ETH per transaction), the reason could be lack of enough liquidity in third party bridges or that users with high volume of assets prefer to use official native bridge.

Now, let's look at daily count of distinct wallets and volume on those two bridges:

Conclusion:

• Deposit from ETH to OP via native bridge is more popular than other third party bridges.
• Withdraw ETH from Optimism to ETH blockchain takes 7 days via native network, so users with less assets prefer using third party bridges to withdraw their assets.
