What is Base and Why It Matters
Base is an Ethereum Layer 2 scaling solution developed by Coinbase. It operates as an Optimistic Rollup built on top of the Ethereum mainnet. The main goal of Base is to create a secure, low-cost, and developer-friendly environment that can bring the next billion users into the crypto economy.
The network positions itself as a complementary technology to Ethereum rather than a competitor. Base aims to scale Ethereum by handling transactions more efficiently while still relying on Ethereum's security. The platform offers one-second transaction times and costs less than one cent per transaction. This makes it accessible to users around the world who might find Ethereum's gas fees too expensive.
One important thing to note is that Base plans to issue its own network token — BASE. The network uses bridged ETH for gas fees previously. This decision sets Base apart from many other Layer 2 solutions that have launched their own tokens. For users, this means they don't need to acquire a new asset just to interact with the network.

How Base Technology Works
Base is built on the OP Stack, which is an open-source and modular framework developed by Optimism. The network specifically uses the Bedrock release of the OP Stack. This version is designed to be as close to Ethereum as possible, which makes it easier for developers to port their applications.
As an Optimistic Rollup, Base processes transactions off-chain and bundles them together into batches. These batches are then submitted to Ethereum Layer 1 for validation. The system assumes transactions are valid unless someone challenges them during a specified time window. This approach is called "optimistic" because it trusts transactions by default.
Every Base transaction has two cost components:
- L2 Execution Fee: The cost for running the transaction on the Layer 2 network
- L1 Security Fee: The estimated cost to publish the transaction data on Ethereum mainnet
The L1 security fee is usually higher than the L2 execution fee. It also changes based on how congested the Ethereum network is at any given time. Base enforces a per-transaction gas maximum of 25,000,000 gas. This limit is expected to change around January 2026 when Fusaka's EIP-7825 will likely lower it to 16,777,216 gas.
Base Development Timeline and History
Base has moved quickly from announcement to mainnet launch and continues to develop its decentralization roadmap.
Base Announced
Coinbase revealed Base as an Ethereum Layer 2 built on OP Stack, positioning it as a gateway for mainstream users and developers to access onchain applications with low fees and Ethereum level security.
Mainnet Launch
Base launched its mainnet for developers, enabling smart contract deployment and live applications while carefully controlling early access to ensure network stability.
Public Access
Base opened fully to the public, allowing unrestricted user transactions and bridging. This event triggered rapid growth in users, apps, and total value locked.
Fault Proofs
Base advanced decentralized fault proof development, a key step toward reducing trust assumptions and aligning more closely with Ethereum rollup security standards.
Fee Scaling
Network upgrades lowered transaction costs and improved throughput during peak demand, making Base more viable for consumer apps and high frequency use cases.
Superchain Growth
Base expanded interoperability within the OP Superchain, improving cross network liquidity and coordination while maintaining Ethereum settlement guarantees.
Fault Proofs Live
Decentralized fault proofs became fully active, significantly reducing reliance on centralized operators and strengthening Base’s trust minimization.
Stage One
Base progressed toward Stage One rollup maturity, meaning withdrawals and safety mechanisms no longer depended on centralized control paths.
App Scaling
Base shifted focus toward large scale consumer applications, optimizing UX, throughput, and tooling to support payments, social, and onchain identity use cases.
Coinbase developed Base based on its background in crypto product development. The company joined Optimism as a second Core Dev team working on the open-source OP Stack. This collaboration has contributed to the technical development of both projects.
Key People Behind Base
Several important figures have shaped the development and growth of Base.
Jesse Pollak led the project to create the Ethereum L2 solution. His vision focuses on building a global on-chain economy that anyone can participate in. Pollak has been the public face of Base and has played a major role in driving adoption.
Brian Armstrong, the CEO of Coinbase, has publicly expressed strong support for the network. He has stated that "on-chain payments are the future," which shows how central Base is to Coinbase's long-term strategy.
From the institutional side, Naveen Mallela from JPMorgan has highlighted the instant settlements that Base enables. He noted that deposit tokens on Base offer compelling alternatives for institutions looking for faster and more efficient settlement options.
Base vs. Ethereum: Key Differences
Users and developers can easily move assets between Base and Ethereum. The official Base bridge and many compatible wallets support this transfer process. This interoperability means users don't have to choose between networks permanently.
How Base Funds Its Ecosystem
Base supports its ecosystem and builders through several funding programs. The network has delivered grants to more than 1,000 builders so far.
Base Ecosystem Fund is managed by Coinbase Ventures along with other venture capital firms. This fund backs early-stage projects at the pre-seed and seed stages. It focuses on teams building innovative applications on Base.
Base Grants are retroactive awards given to projects that have already shipped working prototypes. These grants range from 1 to 5 ETH and reward builders who have demonstrated real progress.
Base Builder Rewards distribute 2 ETH weekly to active builders within the ecosystem. This ongoing support helps developers continue their work without waiting for large funding rounds.
Base Batches are structured programs that provide mentorship and distribution opportunities. Some rounds have awarded over $1 million in total funding. These programs help projects grow beyond just receiving capital.
Paymaster Gas Credits help developers create gasless applications. By removing the friction of gas fees for end users, these credits make onboarding new users much easier.
The ecosystem has also attracted significant venture capital investment. For example, the blockchain-based game Parallel raised $35 million while building on Base. This shows that serious capital continues to flow into the network.
Base Use Cases and Ecosystem
Base is designed to support a wide range of decentralized applications. The network offers high-quality tooling that makes it easier for developers to build and deploy their projects.
Decentralized Finance (DeFi) is one of the strongest use cases for Base. The network provides a scalable environment for lending platforms, decentralized exchanges, and yield farming protocols. Low fees and fast transactions make DeFi more accessible to everyday users. Popular protocols like Uniswap and PancakeSwap have integrated Base support.
Gaming and Virtual Worlds benefit from the network's scalability and low costs. Base can support immersive gaming experiences with in-game economies that require many small transactions. RPGs, MMORPGs, and NFT-based games all work well on the network. The blockchain game Parallel uses Base for its in-game currency.
Non-Fungible Tokens (NFTs) are another major use case. Marketplaces like OpenSea have integrated Base, which allows artists and collectors to trade with lower costs. The reduced fees make it practical to mint and trade lower-value NFTs that would be too expensive on Ethereum mainnet.
Web3 Social Media platforms use Base for membership systems, loyalty rewards, community currencies, and event management. These applications give users more control over their content and data compared to traditional social platforms.
Tokenization of real-world assets represents a growing opportunity. Base can be used to tokenize real estate, intellectual property, and other assets. This opens new possibilities for fractional ownership and global trading.
The Base ecosystem benefits from seamless integration with Coinbase's products. Developers get access to over 110 million verified users and $80 billion in assets within the Coinbase ecosystem. This built-in distribution is a major advantage that few other Layer 2 networks can match.
Recent Controversies and Challenges
Base has faced some challenges that highlight the risks of building in the crypto space.
The most significant recent issue involves Base creator Jesse Pollak. He has faced criticism for publicly interacting with and seemingly supporting a meme token associated with rapper Soulja Boy. This particular token has a history of alleged scam claims. Some holders have reportedly suffered substantial losses.
The incident has reignited concerns about celebrity crypto promotions. When a major network founder appears to endorse volatile or risky assets, it creates potential conflicts of interest. Critics argue that Pollak's public support could mislead users into thinking the token is safe or endorsed by Base.
This controversy highlights a broader tension in the crypto industry. Network leaders want to support their ecosystems and engage with communities. But this engagement can sometimes blur the line between personal interest and official endorsement. The fallout from this incident may lead to more careful communication from Base leadership going forward.
Institutional Adoption on Base
Base has become a platform for institutional financial innovation. JPMorgan Chase has made particularly notable moves on the network.
JPMorgan launched the JPMD token on Base in November 2025. This is a yield-bearing USD deposit instrument designed for institutional use. It enables instant, 24/7 transactional capabilities that traditional banking systems cannot match. The deployment of JPMD enhances liquidity and settlement speed for institutions using the network.
The impact of this move is significant. Rapid settlements on Base offer a compelling alternative to traditional financial mechanisms. Institutions can now settle transactions in seconds rather than days. This efficiency could reshape how large financial players think about blockchain technology.
JPMorgan is also launching the "My OnChain Net Yield Fund" (MONY). This tokenized money market fund would operate on Ethereum and targets a $100 million initial investment. The combination of JPMD on Base and MONY on Ethereum shows JPMorgan's growing commitment to blockchain infrastructure.
What Base Means for Ethereum Scaling
Base represents a significant step forward in Ethereum's scaling roadmap. By handling transactions off-chain while inheriting Ethereum's security, it offers a practical solution to the network's congestion problems.
The fact that Coinbase built Base gives the network unique advantages. The integration with Coinbase's existing user base and products creates a distribution channel that most Layer 2 networks lack. This could accelerate mainstream adoption of on-chain applications.
The absence of a native token is also noteworthy. By using bridged ETH, Base avoids the complexity and speculation that often surrounds new token launches. Users can participate in the ecosystem without needing to acquire and understand a new asset.
Looking ahead, Base's success will depend on continued decentralization and ecosystem growth. The network is currently more centralized than Ethereum because Coinbase operates the sequencer. The roadmap includes plans to progressively decentralize this infrastructure. How well Base executes on these plans will determine whether it can maintain trust as it scales.
For developers and users, Base offers a low-cost entry point into the on-chain economy. The combination of Ethereum security, low fees, and Coinbase integration makes it an attractive option for both new and experienced crypto participants. As institutional players like JPMorgan continue to build on the network, Base may become a bridge between traditional finance and the crypto economy.
