Polygon PoS: The Ahmedabad Upgrade Is Live on Mainnet

After two weeks on the Amoy testnet, the Ahmedabad upgrade will go live on mainnet at block #62278656. At the current rate, that block height is expected to be reached on September 25. 

Collectively, this upgrade brings improved developer and user experience:

• Changes token symbol on Polygon PoS from MATIC to POL, as well as WMATIC to WPOL;
• Enables developers to build more complex contract deployments and logics with increased code size, from 24KB to 32KB 
• Saves stuck bridge transactions by allowing a replay of failed state syncs, improving observability of the network’s plasma bridge.

The Ahmedabad Hardfork (PIP-37) includes three Polygon Improvement Proposals:  

• PIP-30: Increase Max Code Size
• PIP-36: Replay Failed State Syncs
• PIP-45: Token Symbol Change

All node operators including infra providers and validators have already upgraded to the latest version of Bor (>= v1.4.0) and Erigon (>= 2.60.8).

What’s in Ahmedabad? 

PIP-30 increases the max code size from 24KB to 32KB, allowing dApp devs to deploy more complex contracts without resorting to alternative (and less direct) development patterns. 

PIP-36 addresses a gas pricing issue that followed Ethereum’s Berlin hardfork and which caused certain POL (formerly MATIC) transactions to be locked in the plasma bridge. PIP-36 patches the bug and makes it possible to replay failed state syncs, improving overall observability of the network’s plasma bridge. 

Finally, PIP-45 follows the recent (and highly anticipated) POL migration to change the token symbol of the native token on PoS from MATIC to POL. and WMATIC to WPOL.
