PumpFun, the memecoin launchpad that has exploded in popularity in 2025, could be quietly preparing to launch its own EVM-compatible blockchain—alongside a host of new features—according to leaked API documentation uncovered through public domain research.
The documents, accessible via PumpFun’s domain api.pump.fun, reveal a sprawling backend infrastructure that includes endpoints for subscriptions, token launches, videos, order management, and Stripe integration. Blockchain analysts believe this indicates a major expansion beyond memecoins and into broader DeFi territory.
One of the most revealing elements is the presence of “orderbook” architecture and “approval” terminology, both commonly associated with Ethereum-based chains. This, along with token creation and subscription pricing tools, suggests that PumpFun may be building its own EVM-compatible network to power future launches.
Also included in the documentation are social features—user posts, live broadcasts, and video content—alongside integration with Privy (now part of Stripe), hinting at a future social trading environment.
While PumpFun has yet to confirm any of this, the scale and scope of the leaked infrastructure strongly point to a much larger vision for the platform. Whether this leads to a full blockchain launch remains to be seen, but the signs are all there.
