The old GMX RewardRouters have been disabled, all users will be migrated to the new staking structure today to allow rewards to be received in GMX tokens
Rewards will be distributed in GMX tokens starting from this coming Wednesday, 30 Oct 2024
Note that GMX token buybacks have also been enabled
As fees accumulate in GMX V1 and V2, any user can call the claim and buyback function to swap the pending fees for WETH / WAVAX / GMX based on the appropriate ratios and based on the configured buyback batch size
