Solar is in a maintenance-only state. There is no active development team and no further protocol updates are planned. The network continues to operate through its independent block producers, and the Foundation maintains seed infrastructure and this record on a best-effort basis so the chain remains reachable for existing holders and integrations.
Following the resignation of the project's lead developer in November 2025 (statement), the Foundation published a full Project Status Update (January 2026) and held an open governance vote on an optional path forward. After that vote did not reach quorum, no successor development team came forward. Solar remains open for any credible organization to steward — see Get involved.
Last protocol release: Core 4.3.1. No further releases are planned; Core 5.0 was never shipped.
Major listings closed in 2025–2026, including Binance spot on 1 April 2026. See exchanges.
The Foundation keeps seed infrastructure and the explorer online — best-effort, no SLA.
