- The Polygon Heimdall v2 upgrade has finally debuted on the mainnet, sparking a 10% price surge for POL.
- Heimdall v2 upgrade modernizes the Polygon PoS network for improved performance, security, and scalability.
Polygon Foundation has announced that the long-awaited Heimdall upgrade has finally gone live on the mainnet. Following the announcement, Polygon’s native asset, POL, saw its price increase by over 10%.
Polygon Gets a New Lift with Heimdall
As revealed in an X post, the team launched the Heimdall v2 upgrade on the Polygon PoS mainnet, together with PIP-43, PIP-44, and PIP-62.
The Polygon Foundation said the team is working full-time to ensure all providers upgrade to Heimdall. They also assured users that the chain is running smoothly and finalizing on the network.
However, the Foundation said the Polygon Portal and Polygon staking app will remain under maintenance for a few more hours.
The Heimdall v2 upgrade is a major hard fork of the Polygon Proof-of-Stake (PoS) network. Polygon Foundation CEO Sandeep Nailwal described Heimdall v2 as the most technically complex hard fork since mainnet launch in 2020.
The Heimdall v2 is at the core of the Polygon PoS ecosystem, bringing major upgrades to the network’s functionality. The upgrade modernizes the Heimdall consensus layer, which manages validators, block producer selection, and state synchronization between Ethereum and Polygon PoS.
As noted in our earlier post, Heimdall v2 upgrade reduces finality from 90 seconds to approximately 5 seconds. This enables faster checkpoints and a smoother user experience. The upgrade also reduces Block times from approximately 5–6 seconds to about 2 seconds, boosting network throughput.
The Polygon Foundation released the Heimdall v2 upgrade on the Amoy Testnet on June 24, 2025. The team leveraged the testnet to validate functionality and identify potential issues in a controlled environment.
To ensure compatibility with the upgraded Heimdall layer, validators imported their signing keys into a new keyring system. This transition was due to the shift from Hex to Base64 encoding.
The Polyon Foundation also advised dApps to increase confirmation thresholds to 256 blocks during the migration to mitigate risks.
As indicated in our earlier discussion, Heimdall v2 upgrade supports Polygon’s goal of scaling to 1,000 transactions per second (TPS) and beyond.
POL Price Regains Momentum
The launch of the Heimdall v2 upgrade has sparked a new rally for POL. Within the past 24 hours, POL surged over 10% to $0.234.
The POL trading volume also surged by over 50% to $221 million. This rally suggests traders are actively trading the digital asset and betting on its future price.
The latest rally for POL is significant as the token faced intense sideways movement over the past month. POL dropped to as low as $0.175 in June, with its daily trading volume decreasing to under $100 million.
The Heimdall v2 mainnet launch is just one among other recent developments in the Polygon ecosystem. In our last update, we examined how Polygon partnered with Agora and the AUSD stablecoin. The partnership focused on establishing AUSD as the native stablecoin powering the AggLayer cross-chain ecosystem.
Furthermore, Polygon recorded a new milestone in the Decentralized Finance (DeFi) space. As we covered in our latest report, Polygon surpassed $100 billion in all-time volume on Uniswap.
