Base is an Ethereum Layer 2 built by Coinbase — the largest US crypto exchange. It combines Coinbase’s 100M+ verified user distribution with OP Stack technology, making it one of the fastest-growing L2s in crypto.
History
Announced and launched by Coinbase in 2023. Built on the OP Stack (Optimism’s open-source framework). Notably, Base has no token — Coinbase chose not to launch one, distinguishing it from every other major L2. Despite no token incentive, Base grew explosively through Coinbase’s distribution. See L2 guide and Optimism guide.
Why Base Matters
- Coinbase distribution: 100M+ verified users can withdraw directly to Base — the largest on-ramp of any L2
- No token: No speculative token, no airdrop farming — usage driven by genuine need
- Consumer focus: Social apps (Farcaster/Warpcast), AI agents, and consumer dApps thrive on Base
- Aerodrome: Base’s dominant DEX. See Aerodrome guide
- OP Stack: Part of the Optimism Superchain — interoperable with OP Mainnet and Mode

Frequently Asked Questions
Can I invest in Base?
Base has no token. You can invest indirectly through Coinbase stock (COIN), OP token (Base contributes to the Superchain), or Base ecosystem tokens (AERO, BRETT). See Aerodrome.
Is Base safe?
Base inherits Ethereum’s security via optimistic rollups. Coinbase operates the sequencer. Funds can always be withdrawn to L1. See security guide.
