Introduction

Optimism bridging

> Optimism is a layer 2 chain, meaning it functions on top of Ethereum mainnet (layer 1). Transactions take place on Optimism, but the data about transactions get posted to mainnet where they are validated. It’s like driving in a less crowded side street while benefiting from the security of a highway. > > credits: coindesk

Dashboard Introduction

This dashboard tries to answer these following questions:

• How many distinct wallets have deposited or withdrawn ETH to Optimism via the native bridge in the last 60 days?
• Visualize your findings.

Methodology

Results

Optimism basic stat for last 60 days

• There are about 29k and 0.5k in number of unique deposit and withdraw respectively.
• Number of unique deposit wallet is 98.4% of total number of unique wallet.

• The deposit information for last 60 days can be extracted from ethereum.core.fact_transactions table where to_address is 0x99c9fc46f92e8a1c0dec1b1747d010903e884be1
• On the other hand, the withdraw information can be queried from ethereum.core.fact_traces where from_address is 0x99c9fc46f92e8a1c0dec1b1747d010903e884be1

How many distinct wallets have deposited or withdrawn ETH to Optimism via the native bridge in the last 60 days?

More analysis on ETH amount

• This graph show the ETH deposit (blue) and withdraw (orange) amount in last 60 days.
• The peak for both type appear in the same period.

• This plot show the difference between deposit and withdraw amount in ETH.
• Positive means deposit amount > withdraw amount and vice versa.
• The positive peak is on Jun,1 which is the same day with unique deposit wallet, and deposit amount peaks.

Conclusion

• The difference between deposit and withdraw amount in ETH in last 60 days is around 50k ETH.

To crossing process between layer 1 and layer 2 called bridging. The typical bridge functionality allows an ERC20 token to be deposited and locked on L1 in exchange for an equivalent token on L2 in the same quantity.
