Lightspark Launches Bitcoin L2 Stablecoin Platform to Challenge Traditional Banking Rails

Ex-PayPal exec David Marcus' Lightspark unveiled Grid Global Accounts, an API-first BaaS on Bitcoin Layer-2 Spark, offering dollar accounts, stablecoins, yield, payments, and Visa cards settled via Lightning-compatible rails. Partnering with Cross River Bank, it integrates RTP and FedNow across 65+ countries, competing with Stripe’s Bridge amid GENIUS Act and MiCA regulations. With $175M raised and billions in payment volume, the launch boosts Bitcoin utility, stablecoin demand, and on-chain transactional volumes for platforms and AI agents.
