Solana Processes $4.2B in Monthly Stablecoin Payments as DePIN Commerce Use Cases Emerge

Monthly stablecoin payment volume on Solana reached $4.2 billion in April, according to data from Artemis and Dune Analytics. The figure excludes DeFi trading volume and captures only merchant payments, P2P transfers, and machine-to-machine micropayments — making it arguably the most commercially relevant blockchain payments metric.

Growth is concentrated in two categories: point-of-sale payments in Latin America and Southeast Asia (where Solana Pay integrations now cover 340,000 merchants through partnerships with Stripe and Shopify), and DePIN micropayments (where IoT devices pay each other for bandwidth, compute, and energy in sub-cent increments).

The Helium network (now running on Solana) alone processes $180 million monthly in carrier offload payments, while Render Network pays GPU providers $94 million monthly for distributed compute. These machine-to-machine payments are economically viable only because Solana transaction fees average $0.00025.

"Traditional payment rails can't do a half-cent transaction — the minimum fees make it impossible," said Lily Liu, president of the Solana Foundation. "On Solana, a vending machine can pay a power grid in real time, per kilowatt-hour. That unlocks entirely new commercial models."

Ethereum L2s (Arbitrum, Base, Optimism) collectively process roughly $6.8 billion in monthly stablecoin payments by the same methodology. But Solana's single-chain architecture avoids the liquidity fragmentation that makes L2-to-L2 payments complex for merchants.
