## Updates

### + Resolved — May 21, 5:30 PM

We've completed an hour of monitoring with no further issues. Gas estimates on Polygon Mainnet are now fully aligned with the Chicago hardfork, and the paymaster verification gas limits are returning expected values. This incident is resolved. We apologize for any disruption and appreciate your patience while we worked through the fix.

### x Monitoring — May 21, 4:33 PM

We've released a fix that aligns the execution gas cost with the new hard fork. We're monitoring the situation. 

Update:
We've released a second fix that adjusts the verification gas limits returned by the paymaster.  We're monitoring the situation.  


### x Identified — May 21, 4:09 PM

Polygon Mainnet has undergo a Chicago Hardfork. 

The HF updates gas costs for selected EVM opcodes and precompiles. We're now working on updating our services to align with the execution cost.
