Polkadot Confirms Smooth Asset Hub Migration — 1.63B DOT and 1.5M Accounts Shifted Without Downtime
Polkadot successfully completed the full migration of its Asset Hub on November 4, 2025, marking a major infrastructure upgrade. The operation, conducted by Parity Technologies and the Polkadot Technical Fellowship, involved transferring 1.63 billion DOT across 1,526,324 accounts within 8 hours and 39 minutes. The on-chain migration, which handled 283 MB of chain data and involved 53,407 active stakers, showcased Polkadot's resilience and scalability by completing the process without disrupting the network. The upgrade moved tasks such as staking, assets, and governance to the Asset Hub parachain, allowing the Relay Chain to focus on consensus, security, and inter-chain routing. This transition enhances network speed, lowers transaction costs, and introduces new assets. The success positions Polkadot as a leader over competitors like Ethereum and Cosmos in scalability. Community members, developers, and validators celebrated the smooth transition, and tools like ParaSpell and API Sidecar are enabling access to the new features.

Successful Migration of Polkadot's Asset Hub
Polkadot has attested that its Asset Hub, a significant infrastructure upgrade, has been fully migrated on November 4, 2025. Spearheaded by Parity Technologies and the Polkadot Technical Fellowship, the operation transferred 1.63 billion DOT across 1,526,324 accounts within just 8 hours and 39 minutes. This on-chain migration showcased Polkadot's strength and its capacity for seamless upgrades.
Technical Implementation and Network Stability
The migration, as announced by Parity, involved 283 MB of chain data and engaged 53,407 active stakers. Remarkably, this represented one of the largest blockchain activities in history to be executed without interrupting the network's stability. The process shifted the logic of staking, assets, and governance to the Asset Hub parachain, effectively offloading the core chain from unnecessary tasks. This improvement enables the Relay Chain to focus on consensus, security, and inter-chain routing, enhancing the network's speed and reliability.
Benefits of the Upgrade
With this shift, Polkadot is closer to becoming a modular blockchain framework. The migration promises lower transaction costs and a wider variety of optional assets. Parity Technologies confirmed these benefits, citing similar success in the Kusama migration carried out in October 2025.
Community Acknowledgments and Governance
Following the migration, the Polkadot Digest, shared by @DrW3RK, praised Parity Technologies, the Technical Fellowship, and all contributors to the ecosystem. Currently, the next referendum on upgrading the Asset Hub and Relay Chain to version 2.0.1 is in its voting phase. Additionally, discussions on OpenGov deposit refunds and Kusama parity updates are ongoing. Polkadot's transparency in such processes highlights its strong, community-based governance model.
Setting a New Standard for Blockchain Upgrades
The success of this migration establishes Polkadot as a leader among competitors, including Ethereum and Cosmos, in terms of scalability. Developers are already utilizing tools like ParaSpell and API Sidecar to leverage new Asset Hub features. As of November 5, 2025, community sentiment remains highly favorable, with builders and validators commending the smooth transition.
