Lightspark CEO Launches Grid Global Accounts at Bitcoin 2026 Las Vegas

Marcus demonstrated the account through a character named Barbara, a creator in Mexico receiving a $5,000 payment from a U.S. platform. In the demonstration, she spent at Visa merchants globally, converted funds to Mexican pesos in real time, and sent money to a friend’s Brazilian Pix account in seconds. The same account also held bitcoin natively alongside dollars and stablecoins, all under a single wallet address.

The interoperability extends across networks. “A dollar in a Grid Global Account is a dollar on any network,” Marcus said. It can move to USDC on Solana or to USDT on Optimism, and because Grid runs on Spark, Bitcoin support is built in from the start.

For platforms, Marcus framed every payment feature as a revenue source. Stablecoin yield, foreign exchange on-ramps and off-ramps, Visa card interchange, and Bitcoin buy-and-sell functions each represent income that platforms currently hand off to correspondent banks and payment intermediaries.

Marcus also introduced agent delegation, a feature that lets AI agents execute financial tasks inside a user’s wallet with defined permissions. He demonstrated an integration with Bread, a bitcoin wallet launching in the Apple App Store. Through a Whatsapp-based agent, he showed the system generating a scoped card to buy coffee and sending $500 to a contact in Brazil.

“The agent plans, the policy decides, and the account enforces,” Marcus said. “The user always stays in control.” He closed with a direct answer to a long-running skepticism in the industry. “People said for years that you cannot build this on Bitcoin,” Marcus said. “They were wrong.”
