Base is a Coinbase-backed Layer-2 (L2) rollup built for the Ethereum blockchain. It processes transactions off-chain before submitting a summarized, cryptographically verified batch to the Ethereum mainnet, alleviating congestion, reducing costs, and improving transaction speeds.
As explained, Base has a deep integration with Coinbase, benefiting from direct access to its ecosystem, including users, infrastructure, and strategic partnerships. These key points are the main selling points for developer adoption, providing seamless tools and resources that give the layer 2 a competitive advantage.
This layer 2 is designed to be accessible and user-friendly, being compatible with the Ethereum Virtual Machine (EVM), allowing developers to deploy existing EVM smart contracts.
How Does Base Work?
Base was built on the open-source OP Stack, developed in collaboration with Optimism. The network improves Ethereum’s scalability through transaction aggregation. Instead of processing each transaction individually on the ETH mainnet, it bundles multiple transactions together off-chain using Optimistic Rollups.
These batched transactions are then executed on Base before being submitted to Ethereum in bulk, reducing the computational load on the mainnet. This process not only enhances efficiency but also decreases transaction fees for users.
How Safe is Base?
Base periodically submits summaries of processed transactions, along with cryptographic proofs, back to Ethereum. This finalization ensures that transactions remain verifiable and tamper-proof.
If fraudulent activity is detected, fraud proofs allow disputes to be raised, providing a mechanism to challenge and correct discrepancies before finalization on the mainnet.
Base’s full EVM compatibility allows the migration of dApps into its ecosystem without requiring major modifications, lowering the adoption barrier and allowing developers to access Base’s enhanced scalability without sacrificing Ethereum’s established ecosystem.
Gas Fees
Transactions on Base incur two types of fees: an L2 execution fee for processing transactions on Base and an L1 security fee for publishing the final results on the Ethereum mainnet. While L1 fees remain necessary for security, the L2 execution fees are significantly lower, making Base a more affordable option for users than directly interacting with Ethereum.
How to Use The Base Network
For regular users who wish to benefit from Base’s low fees and high throughput, you just need to follow the steps below:
- Use a compatible wallet like Coinbase Wallet.
- Transfer ETH or supported tokens from Ethereum Layer 1 to Base using a bridging service.
- Once your wallet is connected and funded, access dApps such as DeFi platforms, NFT marketplaces, GameFi apps.
- Transactions on Base require ETH for gas fees, so always maintain a sufficient ETH balance to avoid transaction failures.
Top Base Projects
Base has become a hub for all kinds of dApps and Web3 projects, becoming a DeFi powerhouse for all things crypto, amassing billions in total value locked (TVL). Below are the top projects in the Base ecosystem.
Aerodrome Finance
Aerodrome Finance is Base’s largest DEX, allowing users to swap tokens with minimal slippage and low transaction fees. It leverages advanced algorithms and liquidity pools to optimize trading efficiency, ensuring minimal difference between expected and executed trade prices.

The platform uses two tokens: AERO and veAERO. AERO serves as the native token, distributed to liquidity providers as an incentive, while veAERO functions as a governance token. Users can lock their AERO tokens to receive veAERO, allowing them to participate in the platform’s decision-making processes.
Morpho
Morpho is a decentralized lending protocol that provides permissionless lending. It allows users to create custom lending markets without requiring additional approval.

Morpho offers higher collateralization factors, improved interest rates, and significantly lower gas costs compared to traditional lending platforms. Each lending market is isolated, enabling precise risk management and the potential for higher loan-to-value ratios.
Echelon Prime
Echelon Prime is a Web3 gaming ecosystem built on the Ethereum blockchain, designed to revolutionize the gaming industry by enabling decentralized gaming economies.

It offers a robust infrastructure that includes smart contract libraries, secure communication protocols, and token distribution frameworks, providing developers with the tools needed to build and sustain Web3 gaming experiences.
Optimistic Rollups vs. Zero-Knowledge Rollups
Optimistic Rollups and Zero-Knowledge Rollups (ZK-rollups) are some of the most popular layer-2 solutions for tackling Ethereum’s scalability issues. Each has distinct validation mechanisms, security models, and performance trade-offs.
Optimistic Rollups assume that all transactions are valid by default. Instead of verifying each transaction immediately, they rely on a fraud-proof mechanism in which network participants have a designated challenge period–typically up to seven days–to contest potentially fraudulent transactions
The delayed finality is a way to ensure dispute resolution, but it also means users may have to wait longer for their transactions, particularly when withdrawing funds back to Ethereum.
ZK-rollups, in contrast, leverage cryptographic validity proofs (ZK proofs) to verify every batch of transactions before submission to Ethereum. These proofs instantly confirm the transactions’ accuracy, allowing for immediate finality and eliminating the need for a challenge period
As a result, ZK rollups enable faster withdrawals and offer a more seamless user experience. However, generating validity proofs is computationally intensive, making this approach more complex and resource-demanding than Optimistic Rollups.
EVM Compatibility
In terms of EVM compatibility, Optimistic Rollups have an edge as they support existing Ethereum smart contracts with little to no modifications, making them easier to implement for developers
ZK-Rollups have historically struggled with EVM compatibility, often requiring smart contracts to be rewritten in specialized languages and therefore increasing development complexity.
Security
ZK-rollups provide cryptographic certainty for every transaction, removing the reliance on external actors for security and making fraud nearly impossible.
Conversely, Optimistic Rollups depend on network participants to detect fraud, so their security model assumes that enough users monitor transactions to challenge invalid ones. This introduces a potential risk if there is insufficient participation in fraud detection.
Privacy
Privacy is another area where ZK-Rollups excel. While Optimistic Rollups post all transaction data on-chain, making details publicly visible, ZK-Rollups only submit validity proofs and state updates, keeping transaction details hidden, making it ideal for identity verification systems or protocols requiring private financial data/transactions.
Cost Efficiency & Use Cases
Optimistic Rollups have lower gas fees for posting transaction batches but incur higher costs during fraud-proof challenges. ZK-Rollups are more expensive due to the computational power needed to generate proofs.
From a practical perspective, Optimistic Rollups are well-suited for applications prioritizing ease of development and interoperability, such as DEXs and synthetic asset platforms
Meanwhile, ZK-Rollups are ideal for use cases that demand high security, privacy, and instant finality, including identity verification and confidential transactions.
