Summary
- Base is an Ethereum Layer 2 (L2) solution developed by Coinbase in collaboration with Optimism, offering a secure, low-cost environment for building decentralized applications (DApps).
- Compatible with all EVM wallets and Coinbase Wallet.
- Use cases include payment apps, token swaps, liquidity provisioning, bridging, and DAO launches.
What is Base?
Base is an Ethereum L2 blockchain launched on August 9, 2023, by Coinbase. It’s notable as the first blockchain introduced by a publicly traded company. Built on OP Stack (Optimism’s open-source framework), Base grants developers access to Coinbase’s ecosystem of 110M verified users and $80B+ in assets.
Key Vision:
- Create a Superchain powered by Optimism.
- No plans for a native token—users should beware of scams offering fake "BASE tokens."
What is Layer 2?
A Layer 2 (L2) blockchain enhances scalability and reduces fees of its Layer 1 (L1) counterpart (e.g., Ethereum) without compromising security.
Types of L2 Solutions:
- State Channels (e.g., Lightning Network).
- Sidechains (e.g., Polygon).
- Rollups (Optimistic, ZK-Rollups).
Popular L2 Networks: Optimism, Polygon, Arbitrum, zkSync.
What is Optimism?
Optimism is an L2 using optimistic rollups:
- Aggregates off-chain transactions into a single batch.
- Uses fraud-proof mechanisms to challenge invalid transactions.
Use Cases for Base
1. Payment Apps
- Example: Beam (supports USDC/Eco tokens, fiat-crypto conversions).
2. Token Swaps
- DEXs like Uniswap, Maverick operate on Base.
3. Liquidity Provisioning
- Earn fees via BaseSwap, Dackieswap liquidity pools.
4. Bridging
- Use Base Bridge to move ERC-20 tokens between Ethereum/Base.
- Bridging times: Ethereum → Base (~minutes), Base → Ethereum (~7 days).
5. DAO Launches
- Tools like Aragon enable no-code DAO creation.
Will There Be a BASE Token?
Coinbase confirms no plans for a native token. However, future airdrops (unannounced) could reward early adopters.
How to Connect to Base
Via Coinbase Wallet:
- Open the browser extension.
- Connect to a Base app (e.g., BaseSwap).
- Select Base from the network dropdown.
Via MetaMask:
Add Base manually:
- Network Name: Base
- RPC URL: [Provided by Base]

- Save and switch networks.
Benefits of Base
✅ Low Cost: Optimistic rollups reduce gas fees.
✅ Accessibility: EVM compatibility simplifies development.
✅ Scalability: Processes 2,000+ TPS vs. Ethereum’s ~15 TPS.
Drawbacks of Base
⚠️ Centralization: Coinbase is the sole sequencer node.
⚠️ Slow Withdrawals: 7-day delay for Base → Ethereum transfers.
⚠️ Security Risks: Relies on fraud-proof mechanisms vulnerable to data withholding attacks.
Conclusion
By September 2023, Base hit 1M+ users and $385M TVL, surpassing Cardano and Solana in value locked. As the first L2 from a public company, Base bridges traditional finance and Web3, though users must weigh its trade-offs.
