Stablecoin use accelerated as Coinbase expanded its payments stack for businesses, developers, and AI agents. The company said stablecoins processed over $33 trillion in transactions last year, while January 2026 volume exceeded $10 trillion. Coinbase framed the growth as proof that internet-native money is moving from crypto markets into payments, commerce, and automated services across global digital networks and platforms. 

Stablecoin Volume Moves Beyond Crypto Trading

Stablecoin transactions are growing as Coinbase builds out its payments stack. The company said stablecoins handled more than $33 trillion in transactions last year. It also said January 2026 volume crossed $10 trillion.

Coinbase said this growth shows a wider shift in digital payments. Stablecoins are now being used for settlement, commerce, business payments, and automated transactions. They offer 24-hour access, low fees, and global transfer options.

The company said stablecoins have now crossed $300 billion in circulation. Even so, Coinbase noted that most global money still runs on older financial systems. These systems can have delays, higher costs, and limited operating hours.

Coinbase Links USDC Base and x402

Coinbase is positioning itself as a full stack platform for stablecoin payments. Its stack includes USDC, Base, x402, developer tools, and business payment services. The company said these parts are designed to work together. USDC is used as a stable digital unit for payments. Base acts as the onchain settlement layer. Coinbase said Base is built for fast, low-cost, and borderless transactions. 

The x402 standard supports payments for humans and AI agents. Coinbase also offers APIs, SDKs, and payment tools for companies and developers. These tools help businesses accept crypto payments and manage settlement. According to Coinbase the aim is to support onchain payments at scale.

The company also cited wider use by partners. Shopify merchants can accept USDC transactions through Base. Coinbase Business has served more than 2,000 customers since general availability. It has processed over $250 million in onchain payments during its first three months.

AI Agents Add Demand for Internet-Native Money

Coinbase said AI agents are becoming a new source of payment demand. These agents can pay for APIs, data, compute, and digital services. Such payments often need instant settlement and automated rules.

The company pointed to McKinsey projections that agent-driven transactions could reach $3 trillion to $5 trillion by 2030. It added that stablecoins fit this use case because they are programmable, global, and always available. Coinbase has also announced a payments integration with Nium. 

The service lets customers fund payments in USDC and settle in local fiat across more than 190 countries. The company said more partner integrations are in development. The stablecoin market is still small compared with global money supply. Coinbase said this leaves room for wider use across finance, commerce, and software. Its current strategy centers on regulated stablecoins, onchain settlement, and developer infrastructure.
