# Settlement - Ethereum ## **Eclipse Mainnet: Key Features and Security Benefits** ### **Validating Bridge Integration**: Eclipse Mainnet includes a validating bridge built directly into its infrastructure. This bridge plays a critical role in establishing the "canonical chain," which is respected by all Eclipse nodes. ### **Concurrent Ethereum Full Nodes**: To ensure accurate transaction sequencing, Eclipse nodes must run a full Ethereum node alongside the Eclipse node. This integration brings Ethereum’s security benefits to the Eclipse network. ### **Security Features**: * The validating bridge authenticates all transactions, preventing invalid states from being submitted to the Eclipse network. * Guarantees "eventual liveness," ensuring the network continues to function even if the sequencer fails or attempts censorship. * Offers **censorship resistance**, allowing users to force their transactions through the bridge even if Layer 2 censorship occurs. ### **Ethereum L2 Classification**: * Eclipse Mainnet is classified as part of Ethereum Layer 2 networks, similar to validiums and optimums. ### **Ethereum as the Preferred Currency**: * Given the importance of Ethereum-native assets in DeFi and NFT markets, **Ethereum (ETH)** is the chosen decentralized currency for Eclipse Mainnet. * ETH will also be used as the gas token for transactions on the network. ### **Future Fee Flexibility**: * **Fee abstraction** is planned, allowing users to pay gas fees with tokens like USDC. * There are currently no plans to introduce a proprietary token for Eclipse Mainnet. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
