MegaETH shuts Mega Mafia accelerator as MegaETH graduates migrate to Base, Monad and multichain

MegaETH has ended its flagship startup programme, “Mega Mafia”, after two cohorts. The stated reason is that the accelerator’s best-known graduates moved to other ecosystems, breaking the model’s feedback loop. Around 20 teams raised roughly $80m (pre-seed to Series A) during the programme. MegaETH says it will not run “MegaMafia 3.0” and will instead focus resources on first-party consumer products and “OMEGA apps” that are more natively enabled by MegaETH’s stack. Notable migration outcomes reported include: GTE building its own chain; Noise launching on Base; HelloTrade moving to Monad; and Cap adopting a multichain strategy. The announcement also frames the shift as a move away from subsidising broad third-party experiments toward shipping products MegaETH controls. For 2026 chain selection, the article argues that teams increasingly choose where distribution, liquidity and compounding network effects already exist—typically mainstream L2s with better on-ramps (e.g., Base), performance-focused environments (e.g., Monad), or custom/app chains when control over fees and blockspace is critical. For traders, the practical takeaway is that application-layer liquidity and user flows may fragment across chains, potentially affecting routing, fee dynamics and token/liquidity interactions around migrating apps. Expect short-term volatility around cutover periods, while longer-term impact depends on whether MegaETH first-party/OMEGA products attract durable users.
