Brian Armstrong Says Base Is the Best Chain for Trading, Payments, and Agents

Key Takeaways:

Coinbase CEO Brian Armstrong named Base the top chain for trading, payments, and AI agents on April 23, 2026. Base commands roughly 46% of all Ethereum L2 decentralized finance TVL, outpacing Arbitrum across major activity metrics. Armstrong’s comments follow Base’s Solana bridge launch and Coinbase’s push into UK stablecoin payments.

Armstrong’s Three-Pronged Case for Base

Armstrong named trading, payments, and agents as Base’s three defining verticals. The statement arrives as Base holds approximately 46% of all decentralized finance ( DeFi) TVL across Ethereum L2 networks, having surpassed both Optimism and Arbitrum to become the dominant rollup in the ecosystem.

Daily active wallets, decentralized exchange ( DEX) volumes, and net inflows on Base have consistently outperformed rivals through 2025 and into 2026, even as competing networks shed users after incentive cycles wound down.

Built on the OP Stack and incubated by Coinbase, Base launched in August 2023. Coinbase has since committed to storing more of its corporate and customer USDC reserves on the chain, reinforcing Base’s credentials as a payment-grade infrastructure layer. The PACE Act, currently under review in the US, would push the Federal Reserve to open its payment systems to nonbanks and crypto firms and could significantly accelerate Base’s adoption as a payments rail if passed.

The Agent Economy and What Comes Next

The AI agent angle is where Armstrong’s claim is most forward-looking, given that Base has become a preferred deployment chain for autonomous agents performing onchain tasks (ranging from portfolio execution to real-time payment routing). Low transaction fees and deep integration with Coinbase’s developer ecosystem give it a structural edge over higher-cost alternatives.

Armstrong also stated separately that stablecoins are “the best form of money” and are heading to the UK, positioning Base as a regulated stablecoin conduit across major jurisdictions. Circle and OSL have already expanded USDC access across Asia, a move that complements Base’s payment rails thesis.

Back in the US, the SEC has been facing mounting pressure to formalize DeFi rules, an outcome that would define how agent and payment infrastructure on Base is regulated going forward.

Armstrong stopped short of providing specific metrics to support the claim, but onchain data largely makes his case without them.
