If Polymarket launches an Ethereum L2 and migrates the entire system (including order matching and settlement) to run on its own L2, while implementing a fully on-chain order book (CLOB), it could theoretically solve the synchronization issues caused by the hybrid architecture. Polymarket currently uses a "off-chain matching + on-chain settlement" hybrid model: orders are quickly matched off-chain and then submitted to the Polygon chain for fund settlement. The advantage is lower gas fees and faster user experience. However, it introduces a time gap (usually a few seconds to over ten seconds) between the off-chain state and the on-chain state. Attackers exploit this gap by placing orders via API, matching them, and then quickly draining funds on-chain, causing settlement failures and forcibly removing other market makers' orders, creating a vacuum in the order book. If Polymarket had its own L2, it could enable atomic execution of both order matching and settlement on-chain. Without off-chain components, there would be no state synchronization issues. All operations (such as signature verification and fund transfers) would be completed within the same transaction, preventing attackers from intervening between matching and settlement. Additionally, Polymarket could optimize the throughput and gas costs of its L2 (e.g., using a dedicated Sequencer or App-Specific Rollup) to support high-frequency on-chain CLOB without sacrificing too much performance.
