Base by Coinbase uses optimistic rollups, no native token, and processes transactions off‑chain with ETH gas fees. Learn its architecture, usage stats and what
Base, Coinbase’s Ethereum Layer‑2 built on the OP Stack, processes transactions off‑chain via optimistic rollups while settling and securing them on Ethereum mainnet [1]. The design cuts gas costs and boosts throughput, positioning Base as a leading L2 for consumer‑focused dApps and NFT projects.

Base runs transactions on an off‑chain sequencer operated by Coinbase, batching compressed data for submission to Ethereum. Because rollup transactions are assumed valid unless challenged during a dispute window, the model reduces fees while retaining Ethereum’s finality guarantees [1]. The reliance on Ethereum for dispute resolution means that Base inherits the same censorship‑resistance and validator security as the base chain.
Since its 2022 launch, Base has become one of the most active Ethereum L2s by transaction volume and active address count, driven largely by Coinbase’s fiat onboarding tools and the ease of using existing Ethereum wallets [1]. The network’s lack of a native token eliminates speculative liquidity fragmentation, aligning incentives directly with ETH gas fees and simplifying user experience. Coinbase has hinted at a future token launch, but no schedule or specifications have been confirmed [1].

|---|---|
| Token | None (fees paid in ETH) |
| Sequencer operator | Coinbase (single sequencer) |
| Decentralisation roadmap | Gradual, moving toward multi‑sequencer OP Stack model |
Base’s significance lies in its hybrid approach: it offers consumer‑grade performance and low fees while anchoring security to Ethereum, making it a key bridge for mainstream users entering the decentralized web. The open question is how quickly the network can dilute Coinbase’s sequencer control without compromising the user experience that has driven its rapid adoption.

Because increasing user activity has led to network congestion, high gas fees, and slower transaction speeds, which L2 solutions aim to alleviate without changing Ethereum’s base protocol.
A Layer 2 blockchain works alongside the main chain, processing transactions off‑chain and then submitting them in batches to improve speed and reduce costs.
Unichain claims it can reduce transaction fees by up to 95% compared to Ethereum by moving smart‑contract execution to its own network and using roll‑up technology.
The sources list Polygon, Arbitrum, Optimism, Immutable‑X, and xDAI as prominent Ethereum Layer 2 networks.
Unichain is in the testnet phase, providing developers with resources to build and test applications before a full launch.
