Harmony is set to shut down its block explorer service at explorer.harmony.one on November 18, 2026. Users must export all transaction records dated before January 1, 2025, before the service goes offline to prevent permanent data loss.
Why it matters
Operators relying on Harmony blockchain audit trails must transition their record-keeping workflows to accommodate the upcoming infrastructure shift. Businesses holding pre-2025 financial documentation on the network face a strict cutoff for manual data extraction.
The shutdown of the Harmony block explorer on November 18, 2026, marks the end of access for all data created before January 1, 2025. Businesses must manually export all prior records to maintain compliance or audit continuity.
The players
Harmony
A blockchain network platform providing distributed ledger services and infrastructure for digital transactions.
The details
The decommissioning of the explorer.harmony.one interface requires users to manually retrieve transaction history through the site's export function before the November deadline. While Harmony plans to host transaction data from January 1, 2025, onward via a new lookup tool at migrate.country, any financial or operational records existing before this date will not be accessible through the new system.
Timeline
January 1, 2025: Start date for transaction data moving to the new lookup tool.
November 18, 2026: Official closure of the Harmony block explorer service and export deadline.
Market Landscape
This move signals a broader industry trend where blockchain networks shift from maintaining comprehensive, long-term block explorers to fragmented, tiered data access models. It mirrors recent efforts by network operators to optimize infrastructure costs by offloading historical data hosting.
Business operators with historical transaction data on the Harmony network should initiate a full audit and export of pre-2025 records immediately. Future retrieval for these older files will be restricted, making current manual documentation an essential step for ongoing financial compliance.
The takeaway
The transition to the new migrate.country tool effectively creates a permanent boundary for ledger accessibility. Operators should verify that all necessary historical documentation is downloaded and archived in internal systems well before the November 18, 2026, cutoff date.
What happens next
Users must complete all manual data exports from the Harmony block explorer by November 18, 2026, to avoid losing historical transaction records.
