WalletConnect Pay Adds Solana, Making SOL and Stablecoins Spendable at Merchants

WalletConnect has added Solana to its WalletConnect Pay merchant payment platform, enabling users to spend SOL, USDC, and USDT at any merchant that accepts the protocol. The Solana Foundation confirmed the integration in its May 2026 ecosystem roundup, which described it as "expanding merchant stablecoin and token acceptance to eligible participants."

WalletConnect Pay operates as a payment abstraction layer sitting on top of WalletConnect's existing wallet connectivity infrastructure. Merchants and payment service providers integrate once, gaining access to the network's 700-plus compatible wallets and 55.5 million active users without building separate wallet logic for each chain they want to support. The official token and chain coverage documentation lists all three Solana assets in general availability, with USDC and USDT offering fiat settlement in USD or EUR via offramp partners, and SOL settling directly in crypto.

How Settlement Works on Solana

The three Solana assets carry different settlement paths. USDC and USDT can convert to fiat through WalletConnect's offramp partners before reaching the merchant, meaning a retailer accepting USDC does not necessarily need to hold stablecoin positions: the offramp handles conversion to dollars or euros. Native SOL settles in direct crypto, without a fiat conversion step. The documentation notes that fiat settlement availability "depends on offramp partner support per token and chain," so merchant access to fiat offramps will vary depending on their payment service provider.

This mirrors the approach Mastercard took when it named Solana as one of eight blockchains for always-on stablecoin settlement in June, in which merchants receive USDC, PYUSD, or other stablecoins through a single integration rather than per-chain backend work. As that coverage showed, the structural bet across payments infrastructure is on USDC as the Solana settlement rail of choice, and WalletConnect Pay's setup fits that pattern.

Where the Infrastructure Is Deployed

The WalletConnect network processed over $400 billion in volume in 2025, a 119% increase year over year, according to the company's year-ahead blog post. The platform is already embedded in the stacks of Stripe, Coinbase Commerce, SumSub, and MoonPay, meaning Solana payment support flows through those integrations without requiring those providers to build separate Solana checkout logic.

WalletConnect Pay also has a physical retail footprint through a partnership with iMin, a smart POS terminal manufacturer operating in more than 100 countries across retail, hospitality, food service, healthcare, and logistics. That integration, announced April 21, brought WalletConnect Pay natively to Android-based POS hardware, with no additional hardware required. Solana's addition to the supported chain list means Solana assets are in scope for those point-of-sale flows.

CEO Jess Houlgrave has framed the direction plainly: "WalletConnect will still be the defacto connectivity layer across the financial internet, but it's time to bring the ecosystem we support into the real world, to the checkout."

May 2026 Payments Pattern

The WalletConnect integration was one of several payments infrastructure moves that landed in May. Solana's share of global USDC supply reached 10.3% in early June, with Visa and Mastercard identified as structural institutional demand drivers. Western Union launched a stablecoin on Solana via Anchorage Digital, and Cash App rolled out USDC support including Solana in the same period.

WalletConnect Pay's Solana support extends that arc from institutional settlement into consumer-facing checkout. Where the earlier moves were about how businesses and payment networks settle, WalletConnect Pay is aimed at the actual purchase moment, connecting wallets to merchant checkout flows across existing payment service provider infrastructure.

Solana is the ninth chain on the WalletConnect Pay platform, joining Arbitrum, Base, Polygon, Ethereum, Optimism, BSC, Celo, and Monad.
