Helius Cuts getTransactionsForAddress Cost by 80 Percent, Raises Limit to 1,000 Transactions
Helius overhauled its exclusive RPC method getTransactionsForAddress: 10 instead of 50 credits per 100 transactions, up to 1,000 full transactions per request per the announcement. Relevant for indexers, wallet apps, and forensic tools.
What happened
Helius announced an improvement to its RPC method getTransactionsForAddress on 15 May 2026 at 18:57 UTC. Per the Helius X post, the method is “5x cheaper and 10x more powerful.”
The two core changes
1. Cost reduced: Instead of the previous 50 credits, the method now costs 10 credits per 100 returned transactions. This is confirmed by the official Helius RPC documentation: “Full transactions cost 10 credits per 100 returned; signatures-only responses cost 10 credits flat.” An 80 percent reduction.
2. Limit raised:
Per the X post, the method now returns up to 1,000 full transactions per request (previously 100). Verification note: the official RPC documentation at research time still shows a limit of 100 for transactionDetails: full (1,000 only for signatures-only). The doc update for the new full limit appears not yet fully live — the X post as primary source is unambiguous.
What getTransactionsForAddress does
The method is a Helius-exclusive RPC method for address transaction history. It overcomes the limitations of standard getSignaturesForAddress through bidirectional sorting, advanced filters (slot range, block time, status, token account changes), and efficient token-based pagination. Use cases: wallet history display, indexer backfills, activity tracking, and forensic transaction analysis.
Context
For Solana builders, getTransactionsForAddress is one of the central methods for wallet-related data. The 80 percent cost reduction lowers operating costs for anyone querying larger address histories — indexers, wallet frontends, analytics tools, and compliance workflows.
The method is available from the Developer plan upward per the documentation. It is Helius-exclusive, so not available via standard Solana RPC providers. Anyone who previously used getSignaturesForAddress plus separate getTransaction calls for cost reasons now has a cheaper path.
Not financial advice. This article describes an RPC infrastructure change. Concrete cost benefits depend on individual query volume.
