Coinbase CEO Brian Armstrong made a bold declaration on April 23, 2026, naming Base the leading blockchain for trading, payments, and artificial intelligence (AI) agents. The statement reinforces Base's dominance as the largest Ethereum rollup by total value locked (TVL), commanding approximately 46% of all decentralized finance (DeFi) TVL across Ethereum Layer-2 networks — surpassing both Arbitrum and Optimism across major activity metrics such as daily active wallets, decentralized exchange (DEX) volumes, and net inflows throughout 2025 and into 2026.
Trading, Payments, and the Agent Economy
Armstrong outlined three defining verticals for Base: trading, payments, and AI agents. For trading, Base has consistently outperformed rivals as competing networks shed users after incentive cycles ended. In payments, Base recently launched a bridge to Solana, and Coinbase has committed to storing more of its corporate and customer USDC reserves on the chain, strengthening Base's credentials as a payment-grade infrastructure. Armstrong separately stated that stablecoins are “the best form of money” and highlighted Base's role in regulated stablecoin corridors, particularly as Circle and OSL expand USDC access across Asia. The PACE Act, currently under review in the US, would push the Federal Reserve to open its payment systems to nonbanks and crypto firms, potentially accelerating Base's adoption as a payments rail.
The AI agent angle is where Armstrong's claim is most forward-looking. Base has become the preferred deployment chain for autonomous agents performing onchain tasks — from portfolio execution to real-time payment routing — thanks to low transaction fees and deep integration with Coinbase's developer ecosystem. This structural cost advantage makes Base more attractive than higher-cost alternatives for agent-driven applications.
Regulatory Tailwinds and Data Validation
In the UK, Armstrong positioned Base as part of Coinbase's push into stablecoin payments, which aligns with the broader shift toward regulated digital money. In the US, the SEC is facing mounting pressure to formalize DeFi rules — an outcome that would define how agent and payment infrastructure on Base is regulated. While Armstrong did not provide specific metrics to support his claim, onchain data largely makes his case without additional numbers. Base's dominance in TVL, transaction volumes, and developer activity speaks for itself, even as competitors like Arbitrum and zkSync attempt to close the gap.
Base, built on the OP Stack and incubated by Coinbase, launched in August 2023 and has since grown into the dominant Ethereum L2 rollup. With its strong fundamentals and Coinbase's backing, Base appears well-positioned to lead the next wave of trading, payments, and AI-driven onchain activity.
