Safe Cross-Chain Transfer Checklist on Optimism
A pre-transaction checklist designed to reduce avoidable mistakes when bridging.
Why this matters on Optimism
A short pre-flight checklist can prevent irreversible mistakes. Network, token, recipient, route, fee and minimum received should all be confirmed before signing.
Optimism is an Ethereum Layer 2 environment with its own transaction and asset context.
Optimism is part of the Ethereum scaling ecosystem. The same ticker can exist on Ethereum and on Optimism as separate token contracts, so a balance seen on one network cannot be assumed to exist, or to be redeemable at the same value, on the other.
Optimism: what to pay attention to
- Costs: Compare network gas with bridge and route costs, especially for low-value balances.
- Security: Check network, recipient, contract and transaction details before signing.
- Assets and tokens: Verify the Optimism contract address for the asset you intend to move.
A Optimism checklist for this topic
- Allow for a delay between sending and receiving; do not repeat a transfer while one is pending.
- Keep enough native balance on Optimism to pay for the transaction that starts the transfer.
- Review the final recipient address and network before confirming a cross-chain transfer.
- Confirm both the source and destination network, including whether Optimism is one of them.
Bridge from Optimism
Compare network gas with bridge and route costs, especially for low-value balances. On the Avalanche side: verify the asset representation and contract on the selected Avalanche network.
The bridge guide below is informational; any transaction depends on current network conditions and the route shown in the bridge interface.
