Harmony announced that it will permanently close its block explorer, found at explorer.harmony.one, on November 18, 2026. Users must complete manual data exports for any transaction records generated before January 1, 2025, before the service becomes unavailable.
Why it matters
This transition ensures that historical data remains accessible via a new interface while the platform optimizes its technical infrastructure for newer transaction records. Users who rely on older records must act before the deadline to ensure they maintain their personal transaction history.
The transition splits dataset availability, with the explorer service at explorer.harmony.one shutting down entirely on November 18, 2026. Data from January 1, 2025, onwards will move to a new lookup tool hosted at migrate.country.
The players
Harmony
Harmony is a blockchain platform that provides infrastructure for decentralized applications and cross-chain asset transfers.
The details
Users are responsible for manually exporting their own transaction history from the current explorer platform prior to the 2026 shutdown date. Following the closure, only records dated from January 1, 2025, forward will be available through the newly established lookup tool at migrate.country.
Timeline
Records from January 1, 2025, onwards will move to the migration tool.
The block explorer service will close permanently on November 18, 2026.
Market Dynamics
This transition mirrors the standard industry practice seen with platforms like the Ethereum Etherscan block explorer, where infrastructure is periodically updated to maintain performance. It reflects a broader trend of blockchain networks shifting historical data management to specialized tools to streamline main network operations.
Investors and users must manually save their transaction history before the service shutdown to prevent the loss of access to older financial records. Failure to act by the November deadline will limit future lookups exclusively to data from 2025 and beyond.
The takeaway
Blockchain users should regularly audit and export their personal transaction logs as platforms modernize their data hosting requirements. Relying on centralized explorer services indefinitely is risky, as services can shift or sunset as technologies evolve.
What happens next
Users must export all required pre-2025 data from the platform prior to November 18, 2026.
