Polygon (MATIC) (POL) Launches Ahmedabad Upgrade on PoS Mainnet

According to polygon.technology, Polygon (MATIC) has officially launched the Ahmedabad upgrade on its Proof-of-Stake (PoS) mainnet, improving both developer and user experience.

The upgrade, which has been tested on the Amoy testnet for two weeks, has gone live on block #62278656. This important update introduces several notable features.

• Change token symbol: Polygon PoS token symbols have been updated from MATIC to POL and from WMATIC to WPOL.
• Increased code size: Developers can now build more complex contract deployments with code size expanded from 24KB to 32KB.
• Improved Bridge Trading: This upgrade allows for replay of failed state synchronizations, saving aborted bridge transactions and improving observability of the Plasma Bridge on the network.

The Ahmedabad upgrade consists of three Polygon Improvement Proposals (PIPs).

PIP-30: Increased code size

PIP-30 increases the maximum code size from 24KB to 32KB. This change allows decentralized application (dApp) developers to deploy more complex contracts without having to resort to alternative, less direct development patterns.

PIP-36: Gas Pricing and Bridging Issues

PIP-36 addresses a gas price issue that arose after Ethereum’s Berlin hard fork, which caused certain POL (formerly MATIC) transactions to become locked in the Plasma Bridge. This proposal patches this bug and improves the overall observability of the Plasma Bridge on the network by allowing failed state synchronizations to be replayed.

PIP-45: Token Symbol Change

PIP-45 follows the recent migration from MATIC to POL, changing the token symbols of PoS-based tokens from MATIC to POL and from WMATIC to WPOL.

All node operators, including infrastructure providers and validators, have already upgraded to the latest versions of Bor (>= v1.4.0) and Erigon (>= 2.60.8) to ensure a smooth transition to the new system.

Impact on developers and users

According to Polygon, no action is required from developers or end users after this upgrade. These changes are designed to improve the entire ecosystem without any additional steps from the community.
