Polymarket has successfully completed maintenance on its Central Limit Order Book (CLOB), with all services now fully operational. The development team announced the completion on X, stating they will monitor latency and stability closely in the coming hours. Further enhancements are scheduled for next week. In addition, Polymarket has updated its L1 Client interface documentation. The revision changes the constraint from allowing only one active API key per wallet to specifying that creating a new API key (L2 credential) will invalidate the previous one.
