What is Orb?
Orb is a Solana block explorer built and maintained by Helius that launched on October 29, 2025. It runs on the Helius archival system and adds reverse search, slot and time filters, transaction heatmaps and program IDL lookup.
How Orb works
Orb reads Solana history from Helius's archival system, which runs on bare-metal servers with NVMe storage replicated across regions, and uses the custom getTransactionsForAddress RPC method for faster history queries.
A wallet page shows total value, SOL balance, token accounts, NFTs, SNS domains and a Funded by field that names the wallet or tagged exchange account that funded the address, with the date. Unverified tokens are hidden by default to keep spam out of the balance.
Program pages have History, IDL, Verification, security.txt and Authority tabs. The IDL viewer parses instructions, accounts, types, events and errors; the Verification tab shows the hash, date, signer and repo of a verified build; the Authority tab shows who can upgrade the program, for example a Squads multisig. Directories list 3,000+ tagged programs, active validators, token logos and epochs.
How to start with Orb
- Open orbmarkets.io and search by wallet address, token name, mint address or .sol domain; browsing needs no account.
- Orb also supports devnet and testnet, which helps when you debug programs deployed there.
- To trade, open a token page, click the orange Buy button or press B, connect a Solana wallet and confirm the swap in the wallet.
- Helius takes feature requests and support questions on Telegram and Discord.
Orb fees and limits
- Swaps made through the Orb interface carry a 0.1% fee, according to Helius's Orb documentation, and are routed through DFlow's meta aggregator or Jupiter.
Browsing Orb is free. No account or subscription is needed for the explorer itself.
Risks to know before using Orb
- Orb holds no funds, but the Buy button connects your wallet and asks you to sign a swap routed through third-party aggregators, so a trade carries their routing and smart contract risk.
- Check the mint address on the token page before you confirm.
- Orb hides unverified tokens from wallet totals by default, which filters spam but also hides an unverified token you actually own until you deselect the filter.
- The explorer launched on October 29, 2025, so its track record is short.
