# What is Base? Its network, execution and Ethereum settlement Base is an Ethereum rollup: it executes transactions on its own chain and publishes transaction data to Ethereum so nodes can reconstruct the chain. Its sequencer provides quick ordering, while Ethereum publication, finality and the proof system provide later assurances. A Base balance is separate from a mainnet balance, and a fast local confirmation is not the same as completing a withdrawal to Ethereum.

([Base network information](https://docs.base.org/get-started/connect-to-base)) - **Data:** Base publishes compressed transaction data to Ethereum. ([Base network overview](https://docs.base.org/specifications/base-protocol/overview)) - **Stages:** L2 inclusion, Ethereum finality and withdrawal completion are distinct. ([Base transaction finality](https://docs.base.org/specifications/transactions/transaction-finality)) ## Ordering and verification have different jobs The current protocol overview describes a sequencer ordering transactions and independent validators executing the resulting chain. A batcher publishes compressed data to Ethereum, while proposals and proofs support verification of state claims. The documentation retrieved on 2 October 2026 describes a Reth-based execution engine and Base-specific proof components. This article follows that current protocol description rather than assuming every historical architecture label remains complete. Evidence: [Base network overview](https://docs.base.org/specifications/base-protocol/overview) ## Receiving ETH on Base does not fund mainnet gas Suppose a transfer credits 0.05 ETH to your Base account. The balance is on Base even if your mainnet wallet displays the same address. Switching the wallet’s network changes the state you view, not the location of those funds. Use the correct network and supported deposit or withdrawal route. Base’s use of ETH for fees does not merge its balance accounting with Ethereum mainnet.

Withdrawals to Ethereum have additional proof and finalization conditions. Those conditions depend on the active protocol version and proof path. Check the withdrawal’s actual state instead of assuming a generic seven-day rule or treating the local receipt as an L1 payout.

No. It is a separate rollup chain that uses Ethereum for data publication and settlement-related verification. Its account state is separate. Evidence: [Base network overview](https://docs.base.org/specifications/base-protocol/overview); [Base network information](https://docs.base.org/get-started/connect-to-base) ### Does Base’s quick confirmation make every withdrawal immediate? No. A transaction can be included on Base while an L1 withdrawal still needs proof and finalization steps under the current protocol.
