Pump.fun, the memecoin launch platform that dominates Solana trading, has crossed $1 billion in cumulative protocol revenue — making it the first application on Solana to reach that milestone. The achievement underscores how much volume its bonding-curve token launches have captured since the platform's early 2024 debut.

Now the team appears to be looking beyond Solana. On-chain watchers discovered that Pump.fun quietly registered subdomains for four blockchains: Base, Ethereum, BNB Smart Chain (BSC), and Monad. The subdomains — which sit under the main pump.fun domain and are named after each respective network — typically precede smart contract deployments and user-facing front-ends.

The team also removed "Solana" from the location field on its official X profile around the same time, fueling speculation that Pump.fun is repositioning itself as a chain-agnostic platform rather than a Solana-native product.

Why These Chains

Base offers low fees and deep ties to the broader Ethereum ecosystem via Coinbase's infrastructure. BSC brings a large retail user base already comfortable with memecoin trading. Ethereum remains the largest pool of on-chain liquidity. Monad — a newer, high-throughput EVM-compatible chain — represents a bet on emerging networks built for parallel execution.

Together, the four chains would give Pump.fun access to nearly every major retail trading community in crypto.

What Comes Next

No official launch dates have been announced. The visible evidence so far is limited to DNS registrations and profile edits. Traders are watching for test contract deployments, beta front-ends on the new subdomains, and clarity on how the PUMP token — currently tied to Solana activity — might function in a multichain environment.

If the expansion materializes, it would bring Pump.fun's rapid-launch, bonding-curve model to the Base ecosystem for the first time.
