Base (BASE): why Coinbase’s L2 onboards retail users to on‑chain apps
- Base is a new Layer‑2 network that brings low‑cost transactions to Ethereum.
- Coinbase leverages its user base and wallet integration to make on‑chain apps more accessible.
- The result: retail investors can interact with DeFi, NFTs, and gaming without high gas fees.
- Base’s design supports secure, developer-friendly contracts while keeping costs low.
- Eden RWA shows how tokenized real estate benefits from Layer‑2 scalability.
In 2025 the crypto ecosystem is in a transition phase. Ethereum remains the dominant smart‑contract platform, but its high gas fees and congestion have kept many retail users on the sidelines. Coinbase’s launch of Base – a dedicated Layer‑2 (L2) network built atop Ethereum – addresses this gap by offering near‑zero transaction costs while preserving security and compatibility with existing tools.
Base is not just another scaling solution; it represents a strategic move to bring mainstream retail users into the world of on‑chain applications. By integrating directly with Coinbase’s wallet, exchange, and onboarding processes, Base reduces friction for newcomers who are already familiar with Coinbase’s interface.
This article explains what Base is, how it works, why it matters now, and what opportunities and risks it presents to retail investors. We also look at a concrete example – Eden RWA – that demonstrates the practical benefits of L2 tokenization for real‑world assets.
Background & Context
Base is a roll‑up Layer‑2 network built by Coinbase, launched in early 2024. It uses optimistic roll‑ups to bundle multiple transactions off‑chain and submit them to Ethereum as a single commitment. This design keeps the security guarantees of the mainnet while dramatically reducing gas usage.
The timing is key: after years of scaling debates – from sharding proposals to zk‑rollups – developers and users have demanded a reliable, low‑cost solution that is easy to adopt. Base fills this niche by offering:
- Compatibility with Ethereum’s tooling (ERC‑20, ERC‑721, etc.)
- Built‑in bridges for assets from Coinbase’s ecosystem
- A developer portal and SDKs that mirror the familiar Ethereum stack
- Zero or minimal gas fees for end users, thanks to subsidized transaction costs from Coinbase
Coinbase’s reputation as a regulated exchange gives Base an advantage in trust. The company can provide fiat‑onboarding, KYC/AML compliance, and consumer protection that many other L2s lack.
How It Works
The core mechanism behind Base is the optimistic roll‑up model. Here’s how it unfolds step by step:
- User Initiates Transaction: A retail investor opens Coinbase Wallet, selects a DeFi app on Base (e.g., a liquidity pool), and submits a swap.
- Transaction Bundled Off‑Chain: The Base operator collects many such transactions into a single batch. Each transaction is signed by the user but not yet executed on Ethereum.
- Commitment Posted to L1: The operator posts a cryptographic commitment of the entire batch to the Ethereum mainnet. This commitment includes a Merkle root that represents all included actions.
- Challenge Period: During this period, anyone can submit fraud proofs if they suspect an invalid transaction. Coinbase’s own operators also audit batches for compliance and security.
- Finalization & Settlement: After the challenge window closes without disputes, the batch is finalized. The state root is published to L1, and all users’ balances are updated on Base.
- Cross‑Chain Bridge: If a user wants to move assets back to Ethereum or another chain, they use Base’s built‑in bridge. This process involves locking tokens on Base and minting wrapped equivalents elsewhere.
Key actors include:
- Base Operators: Coinbase’s infrastructure that manages roll‑up execution and security.
- Users/Investors: Retail participants who interact with DeFi, NFTs, or gaming on Base.
- Developers: Build dApps using standard Ethereum SDKs; no need to learn new languages.
- Bridge Providers: Enable asset movement across chains while maintaining liquidity.
Market Impact & Use Cases
Base’s low fees and high throughput unlock a range of use cases that were previously cost‑prohibitive on Ethereum:
- DeFi Yield Farming: Users can stake or provide liquidity without paying steep gas, improving net returns.
- NFT Minting & Trading: Artists and collectors can create and swap NFTs with negligible fees, encouraging broader participation.
- Gaming: Play‑to‑earn games on Base allow microtransactions that are economically viable for players.
| Feature | L1 Ethereum (before 2025) | Base L2 (2025+) |
|---|---|---|
| Average Gas Fee (USD) | $10–$30 | $0.01–$0.05 |
| Throughput (tx/s) | 15–30 | 2,000+ |
| User Adoption Barriers | High transaction cost & slow confirmations | Low cost & instant finality |
| Security Model | Native L1 security | Optimistic roll‑up with L1 settlement |
These improvements translate into higher daily active users and a broader range of retail applications, making Base an attractive platform for developers targeting non‑institutional audiences.
Risks, Regulation & Challenges
While Base offers compelling benefits, several risks remain:
- Regulatory Scrutiny: Coinbase’s regulated status is a double‑edge sword. The U.S. SEC and European MiCA regulations could impose stricter oversight on L2 operators, potentially limiting operational flexibility.
- Smart Contract Risk: Although Base reuses Ethereum contracts, bugs in roll‑up logic or bridge code can expose funds. Users must still exercise caution when interacting with new protocols.
- Custody & Liquidity: Base relies on Coinbase’s custodial infrastructure. In a market downturn, liquidity for certain tokens may dry up faster than on L1.
- User Experience: New users need to understand bridging mechanisms and the difference between L1 and L2 assets, which can be confusing.
- Potential Centralization: Coinbase’s role as operator could raise concerns about control over transaction ordering and batch composition.
Real‑world examples of these risks include the 2023 roll‑up security incident where a mis‑sequenced batch caused temporary loss of funds for a small number of users. Coinbase responded swiftly, but the event highlighted that operator malfeasance or software bugs remain tangible threats.
Outlook & Scenarios for 2025+
Bullish scenario: Base’s low fees attract millions of retail users, driving adoption of DeFi and NFT projects. The network becomes a de facto hub for micro‑transactions, and Coinbase leverages its data to offer tailored financial products.
Bearish scenario: Regulatory crackdowns on L2 operators or a major security breach erodes trust. Users migrate back to Ethereum or alternative chains, stalling growth.
Base case: Base sees steady user growth (~10% monthly) as developers release more dApps and Coinbase gradually expands bridge support. Retail investors gain modest but consistent exposure to on‑chain opportunities without high gas costs.
Eden RWA: A Concrete Example of Tokenized Real Estate on Layer‑2
Eden RWA is an investment platform that democratizes access to French Caribbean luxury real estate (Saint‑Barthélemy, Saint‑Martin, Guadeloupe, Martinique). By combining blockchain technology with tangible, yield‑focused assets, Eden offers investors fractional ownership in high‑end villas through ERC‑20 property tokens.
Key features of the Eden RWA model include:
- SPV Ownership: Each villa is owned by a dedicated Special Purpose Vehicle (SCI/SAS) that issues ERC‑20 tokens representing indirect shares.
- Automated Income Distribution: Rental income, collected in USDC stablecoin, flows directly to investors’ Ethereum wallets via smart contracts. This removes traditional banking intermediaries.
- Quarterly Experiential Stays: A bailiff‑certified draw selects a token holder for a free week at the villa, adding an experiential layer that incentivizes holding.
- DAO‑Light Governance: Token holders vote on major decisions (renovation, sale) while maintaining efficient governance without full DAO overhead.
- Transparent P2P Marketplace: Eden’s own marketplace enables primary and secondary token sales, with audited smart contracts ensuring fairness.
- Dual Tokenomics: A platform utility token ($EDEN) for incentives and governance, plus property‑specific ERC‑20 tokens (e.g., STB‑VILLA‑01).
Eden RWA exemplifies how Layer‑2 networks like Base can support complex real‑world asset tokenization. The low transaction costs make it feasible to issue, trade, and manage fractional real estate units on a daily basis without incurring prohibitive gas fees.
