Orb is a full-featured Solana block explorer built and maintained by Helius. Orb officially launched on October 29th, 2025. Orb is powered by Helius’s state-of-the-art archival system, which runs on bare-metal servers with petabyte-scale NVMe storage, replicated across multiple regions for redundancy. Leveraging custom RPC methods such as getTransactionsForAddress, Orb enables faster historical queries, and introduces a suite of advanced explorer features, including reverse search, slot and time-based filtering, transaction heatmaps, and more.
