To withdraw staked RAMA, open the validator you delegated to, click Undelegate, enter the amount, and confirm on Polygon. New exits follow the fast challenge window: 2,400 seconds half period and 4,800 seconds full period (about 1 hour 20 minutes). After the claim window opens, use Withdraw Unbonded.
Important: delegation principal, rewards, claims, and undelegation withdrawals are all handled as RAMA on Polygon.
If you need tokens for Ramestta-side usage or market activity listed as RAMA on Ramestta, bridge from Polygon back to Ramestta after withdrawal.
