OptimismEthereum

Network-specific checks before a cross-chain transaction.

Optimism and Ethereum have separate network contexts. A cross-chain route must account for the source environment, destination environment and the mechanism used to transfer or represent the asset.

Route Intelligence

Source network

Optimism: Optimism is an Ethereum Layer 2 environment with its own transaction and asset context.

Destination network

Ethereum: Ethereum is an EVM network and the base layer for a large ecosystem of tokens, applications and Layer 2 networks.

Asset considerations

On the source side, Verify the Optimism contract address for the asset you intend to move. On the destination side, Verify the ERC-20 contract address and distinguish Ethereum-native assets from representations on other networks.

Fee considerations

Compare network gas with bridge and route costs, especially for low-value balances. On Ethereum, Ethereum gas can make very small balance movements uneconomical, so compare total execution cost with the balance value.

Before You Bridge

  • Source: confirm the asset is actually held on Optimism.
  • Destination: confirm the wallet and destination network.
  • Token: verify the exact asset representation rather than relying on ticker or logo.
  • Costs: compare gas, bridge fees, liquidity, price impact and the final received amount.
  • Security: Check network, recipient, contract and transaction details before signing. At the destination, Pay close attention to contract approvals, transaction details and the exact domain used to initiate a transaction.
Never use a seed phrase or private key to complete a bridge. A legitimate bridge flow should not require either.

Use the Live Bridge Tool

When a live route is available, open Dust Sweeper and review the current quote immediately before signing. Route availability, liquidity and network conditions can change.
