Lightspark, a crypto payments infrastructure company founded by former Meta executive David Marcus, has joined Visa's network as a principal member. This partnership aims to expand Lightspark's stablecoin-powered payment services, deepening integration between crypto infrastructure and traditional financial rails.
Visa's principal member status is typically reserved for financial institutions meeting strict regulatory, capital, and operational requirements. For a crypto-native company like Lightspark, obtaining this designation signals that the firm has cleared compliance thresholds most digital asset startups have not. Principal members can issue cards, acquire merchants, and settle transactions directly on the Visa network rather than operating through a sponsoring bank.
Lightspark has been building out its payments stack beyond this Visa arrangement. The company's CEO launched Grid Global Accounts at Bitcoin 2026 in Las Vegas, a product designed to facilitate cross-border stablecoin transfers. That rollout, combined with the Visa membership, suggests the company is pursuing both traditional and crypto-native distribution channels.
Separately, Visa also announced a partnership with WeFi, co-founded by Tether co-founder Reeve Collins, to enable stablecoin payments for everyday use across Europe, Asia, and Latin America. WeFi operates an on-chain banking platform supporting over 200,000 users across 153 jurisdictions, processing over $150 million in transaction volume in the past month. Visa has been testing stablecoin settlements with volumes reaching an annualized run rate exceeding $3.5 billion as of late 2025, using USD Coin on the Solana blockchain.
The partnership reflects a broader pattern of legacy payment networks moving to accommodate stablecoin settlement. Visa's decision to onboard a stablecoin-focused company as a principal member suggests the network views digital dollar instruments as complementary to its existing infrastructure.
