Frequently asked questions

What is Optimism and how does it work?

Optimism is a layer-2 scaling solution for the Ethereum blockchain that aims to improve scalability and reduce transaction costs. It achieves this through a technology called Optimistic Rollup, which processes transactions off-chain and periodically submits a summary of these transactions to the Ethereum mainnet. This approach enables faster and more cost-effective transactions while leveraging the security of the Ethereum network.

Is Optimism secure for conducting transactions?

Optimism places a strong emphasis on security and leverages the underlying security of the Ethereum network. The Optimistic Rollup design ensures that transactions are validated on-chain, providing a high level of security. Additionally, Optimism conducts regular audits and engages with the Ethereum community to address any vulnerabilities and enhance the overall security of the network.

Can I transfer my tokens between the Ethereum mainnet and Optimism?

Yes! You can use Kado to bridge assets between Ethereum mainnet and Optimism.

What are the benefits of using Optimism for Ethereum users?

Using Optimism offers several benefits for Ethereum users, including: - Faster Transaction Confirmation: Optimism enables faster transaction finality, allowing users to experience near-instantaneous transaction confirmation. - Lower Transaction Costs: By leveraging Optimistic Rollup, users can significantly reduce gas fees, making transactions more affordable. - Improved Scalability: Optimism's layer-2 solution increases Ethereum's capacity, allowing for a higher volume of transactions to be processed simultaneously. - Seamless Integration: Users can interact with decentralized applications (DApps) and smart contracts on the Ethereum mainnet and enjoy the benefits of Optimism's scalability without needing to switch networks.
