Base (L2)
Coinbase's Ethereum L2 built on the OP Stack, launched 2023; known for low fees and Coinbase ecosystem integration.
Base (L2) — Base is an Ethereum Layer 2 network built by Coinbase using the OP Stack (Optimism's open-source rollup framework). Launched in August 2023, Base offers low-cost transactions secured by Ethereum mainnet, with strong adoption driven by Coinbase's user base and the 'onchain summer' ecosystem campaign. It has become one of the top L2s by transaction volume.
What Is Base?
Base is an optimistic rollup that executes transactions off Ethereum mainnet but posts transaction data back to L1 for security. Built on the OP Stack, it benefits from shared development with Optimism and is part of the Superchain vision. Coinbase's backing provides Base with unique advantages: direct fiat on-ramps, regulatory credibility, and access to Coinbase's 100+ million verified users.
Base Ecosystem
Base has attracted a vibrant DeFi and meme coin ecosystem. Aerodrome is the leading DEX, friend.tech pioneered social trading, and numerous meme coins (BRETT, DEGEN, TOSHI) have launched on the chain. Transaction costs on Base are typically $0.01-0.10, making it accessible for high-frequency activities like volume generation and micro-transactions.
Base for Trading
Base's low fees, Ethereum security inheritance, and growing liquidity make it increasingly popular for DeFi trading. OpenLiquid supports Base for volume generation, enabling projects to build trading activity on one of the fastest-growing L2 ecosystems. The chain's EVM compatibility ensures seamless tooling support.

Common questions about Base (L2) in cryptocurrency and DeFi.
No. Base does not have a native token and Coinbase has stated there are no plans to launch one. Gas fees on Base are paid in ETH. This distinguishes Base from other L2s like Arbitrum (ARB) and Optimism (OP) that have governance tokens.
Base transactions typically cost $0.01 to $0.10, roughly 100-1000x cheaper than Ethereum mainnet. After EIP-4844 (proto-danksharding), costs decreased further by reducing the price of posting data to L1.
Base inherits Ethereum's security for finalized transactions. However, as an optimistic rollup, there is a 7-day challenge period for withdrawals to L1. Coinbase currently operates the sole sequencer, creating a centralization vector that is planned to be decentralized over time.
