Not investment advice. Muhabbit scores how much a story may matter, not which way to trade.
Helius has released a beta API for querying historical account state on the Solana mainnet, letting developers request account data as of a specific slot or immediately after a given transaction. The Historical Accounts beta, documented in Helius's official SDK, supports data from mainnet slot 444,959,999 onward, with the getHistoricalAccountInfo endpoint returning account details plus a lastUpdatedAt field pointing to the change that produced that state. A companion method, getHistoricalTokenAccountsByOwner, retrieves the SPL Token and Token-2022 accounts a wallet held at a chosen past point. The tool matters because Solana's standard RPC only exposes current state, forcing indexers and analytics teams to reconstruct balances and positions from raw transaction history. Next, watch for developer adoption and whether Helius expands coverage beyond the beta's slot floor toward full historical depth.
