Although early users may have an adaptation period (any changes require a learning process) when migrating to L2, overall, it is still very cost-effective: One is that the polymarket no longer has to worry about constant congestion or downtime (there have been several interruption events on Polygon), and has its own L2. The polymarket can customize optimization sorters and execution layers to reduce latency. From a user experience perspective, the operation will be smoother (betting/canceling/settling, etc.), and the experience will be better, especially for popular events (such as the World Cup) that will not lag. Secondly, security has been improved. Ethereum L2 inherits the security of the mainnet and can integrate more tools, including native stablecoin support, AI trading agents, etc. The user experience is more seamless (such as wallet interaction). Even if there are interface adaptation issues in the short term, the experience will be more convenient in the long run. Thirdly, although Polygon's gas fees are currently relatively low, the transaction scale has increased and the cost is still not small. Polymarket can further optimize costs by developing L2 on its own, such as through batch processing and cost compression at the DA layer. Overall, the cost may be optimized to a fraction or even one tenth of its previous level (depending on the design); In addition, Polymarket can also develop custom fee models to provide subsidies or zero fee settlements for predicting the market, attracting more users/institutions to participate.
