How should an Optimism wallet handle Layer 2 transfers?
It should keep OP Mainnet explicit from receive address to final confirmation. NordBalticum shows Optimism as a distinct supported network, uses ETH for gas and lets you authorize transactions without handing custody of the wallet to the software provider.
OP Mainnet context
ETH pays network fees
Self-custody authorization
01
Network name stays visible
Optimism is not merged with Ethereum mainnet or another chain that uses the same address format.
02
Fee balance is chain-specific
ETH for gas must be available on Optimism to move assets there.
03
Recipient support is decisive
Only use a deposit route that explicitly accepts the asset on OP Mainnet.
The address does not choose the network for you
EVM-compatible chains can share an address format, so the selected network is essential routing information. Funds sent on Optimism stay on Optimism unless a supported bridge or transfer route moves them elsewhere.
When using an exchange, read the full deposit or withdrawal network label. A token symbol and address match are not enough on their own.
Understand what the wallet can verify
NordBalticum can preserve your selected network and present the destination, amount and fee for review. It cannot guarantee a token contract, third-party bridge or recipient policy.
After broadcast, use the network transaction reference to confirm status independently. Interface timing and blockchain finality are not always identical.

Optimism with the route kept explicit
A clear OP Mainnet context helps separate familiar addresses from the network where value actually moves.
Practical flow
What to do next
1
Choose Optimism
Select OP Mainnet before copying an address or preparing a send.
2
Verify asset support
Match the asset and network against the receiving service's instructions.
3
Keep ETH for gas
Review the fee and authorize only after the final details match your intent.
Security, in plain English
Controls with defined responsibilities
Separate chain context
Optimism actions remain distinguishable from Ethereum and other EVM networks.
Layered access controls
Device authorization, wallet confirmation and optional MFA serve separate purposes.
No silent broadcast
The protected transaction flow requires the user's authorization.
Clear answers
Frequently asked
What asset pays Optimism transaction fees?
Transactions on OP Mainnet normally use ETH held on that network for gas.
Can I use the same address on Optimism and Ethereum?
The EVM address may match, but balances and transactions remain on separate networks.
Does NordBalticum guarantee bridge availability?
No. Bridges are separate protocols or services whose availability, fees and risks can change.
