Coinbase Reveals $50M x402 Payment Growth and New Solana–Base Integration

• x402 adoption is rising fast, processing over $50 million in stablecoin payments recently.
• Coinbase offers crypto as a service, helping banks and fintechs launch crypto features easily.
• Companies can launch custom stablecoins, backed by USDC for payments and rewards.

Coinbase executives say adoption of the x402 payment standard is accelerating, with the system now processing over $50 million in transactions in the past 30 days. The update was shared by Alec Lovett, Head of Infrastructure Businesses at Coinbase, and later echoed by Coinbase CEO Brian Armstrong.

“Crypto as a Service” for Banks and Startups

Coinbase is focusing on making crypto easy for companies to use by offering “crypto as a service” through its developer platform. This allows banks, fintech firms, payment companies, and startups to add crypto features without building everything from scratch. Alec said Coinbase already powers crypto products for major players, including startups, scaling fintechs, and large banks such as JPMorgan and PNC.

The company said that stablecoin payments are gaining traction because they are faster, cheaper, and more global than traditional payment systems. Companies are now using stablecoins to pay vendors, freelancers, and employees, and to manage treasury operations more efficiently.

Coinbase Introduces Custom-Branded Stablecoins

At the center of this push is x402, an open payment standard designed for the internet. The protocol allows stablecoin payment requests to be attached directly to web transactions. Alec said this makes it possible for websites, apps, and even AI agents to send and receive payments seamlessly using stablecoins.

“And one final launch, a product that seamlessly accompanies our custody, payments, and trading products. Today, we’re announcing that you can now create your own custom-branded stablecoin with Coinbase, backed by USDC,” Alec said.

Cross-Chain Support With Solana and Base

At the same time, Coinbase is expanding its cross-chain capabilities. The exchange has added support for Solana (SOL) deposits and withdrawals via the Base network, its Ethereum-aligned blockchain built for scalability and interoperability.

The update connects the Solana and Ethereum ecosystems directly inside Coinbase, allowing users to move SOL between Solana and Base with fewer steps and lower risk. 

With the integration, SOL on Base functions as an ERC-20 compatible asset, meaning it can be used inside Ethereum-based decentralized applications. 

Together, the rise of x402 payments and the Solana-Base connection show Coinbase’s broader strategy.
