A payment protocol jointly developed by Coinbase and Shopify is showing the kind of growth curve that makes crypto-commerce advocates feel vindicated. The Commerce Payments Protocol, which launched on Base in June 2025, has processed roughly $1.7 million in settled USDC volume across approximately 8,000 transactions, with the bulk of that activity concentrated in the most recent weeks.
Of the total volume, around $750,000 was processed in just the two months prior to the latest data, suggesting the protocol hit an inflection point after a slow initial ramp.
How the protocol actually works
The Commerce Payments Protocol is an open-source, permissionless smart contract system deployed on Base, Coinbase’s layer 2 network built on Ethereum. It handles escrow-based payment flows, refund processing, voids, and delayed capture. Six core operations power the system: authorize, capture, charge, void, reclaim, and refund.
USDC serves as the primary payment token. Shopify merchants using the protocol can accept USDC payments through their existing Shopify Payments infrastructure. On the receiving end, merchants get a choice: take payouts in USDC on Base or convert automatically to local currency with no foreign exchange fees.
The numbers behind the growth
As of early February 2026, data from growthepie showed over $1.2 million in USDC processed through the protocol across roughly 3,200 customers and 5,700 merchants. By late February, that cumulative settled volume had climbed to approximately $1.7 million.
The protocol has also diversified beyond its initial Shopify-only merchant base, with operators outside the Shopify ecosystem beginning to build on the open-source infrastructure. Given that the smart contracts are permissionless, any developer can integrate the protocol into their own commerce stack without asking Coinbase or Shopify for permission.
Why this matters beyond the numbers
Instead of asking consumers to figure out wallet connections and gas fees, the protocol embeds itself into Shopify’s existing infrastructure. The merchant doesn’t need to become a crypto expert. The buyer pays in USDC. The settlement happens on Base. The merchant sees money in their preferred currency.
Multiple audits were conducted throughout 2025 before and after the mainnet deployment. A protocol handling escrowed funds needs to be airtight, and the team appears to have taken that seriously.
