DOT What this update covers
Polkadot is launching important updates to its Products Devnet. This is Polkadot's public developer sandbox environment that aims to allow developers to test upcoming features in advance before the network is fully operational and released. This update will be deployed simultaneously in mobile and desktop applications, so this is a broad-based change covering the entire platform rather than a patch for specific issues.
Since 2026, the "Product Test Network" has been a core part of Polkadot's developer strategy. The testnet provides developers with early access to upcoming network features and allows them to conduct risk-free testing without real funding. The test network is built on Paseo, a community-operated Polkadot test network, and is operated by the Paseo team.
Devnet provides a framework for building Web applications that run within the Polkadot host, allowing developers to explore features that go beyond the capabilities of typical blockchain applications. The original intention is to reduce vulnerabilities and security risks through realistic simulations and community collaboration, smooth protocol upgrades, and accelerate the popularization of decentralized applications.
This update appears to be part of this ongoing process, keeping the environment up to date as the broader Polkadot product stack matures for release to the main network.
Actions for developers
This update introduces changes to the Devnet environment that require developers to take specific steps to maintain access. Failure to take action before the update takes effect may render existing settings unusable.
The required operating steps are simple but crucial. All developers must first back up their own Recovery Phrases, then delete existing application backups, and finally reinstall the application. Completing these steps in strict order is key to ensuring that updates take effect smoothly.
Developers currently active on Devnet should act as soon as possible. Missing the migration window can disrupt access to the test environment and affect ongoing work.
