Helius Labs Expands Solana Developer Power With New History API

Helius Labs rolled out a major upgrade for Solana developers. The company launched getTransactionsForAddress, a new history API. The tool allows developers to query every transaction linked to a wallet address. It supports sorting, filtering, and deep historical analysis. Solana shared the update through an official post. An 83-second demo video accompanied the announcement. The video showed live code examples. It also highlighted flexible query options. This release targets one of Solana’s long-standing pain points. Wallet-level transaction history often required complex workarounds. Helius now simplifies that process with a single endpoint.

One API Call Replaces Multiple RPC Methods

The new API merges two existing Solana RPC calls into one. Developers no longer need to chain requests. They can retrieve clean results with a single query. The API supports both forward and backward sorting. It allows filtering by time, slot, and transaction status. Cursor-based pagination enables smooth navigation through large datasets. The system supports up to 1,000 records per request. This structure reduces query complexity. It also lowers infrastructure costs. Helius rebuilt its archival backend to support the tool. The new system runs 2 to 10 times faster than before. Faster queries improve app performance. They also reduce indexing overhead.

Built for Indexing, Backfills, and Analytics

This API targets serious production use cases. Developers can now handle backfills efficiently. Analytics teams can track wallet behavior with precision. Indexers can avoid fragmented data pipelines. The API supports reliable historical access without manual stitching. That matters for explorers, wallets, and compliance tools. It also benefits DeFi dashboards and on-chain analytics platforms. By reducing RPC friction, Helius enables faster development cycles. Teams can ship features with less infrastructure work. This improves the overall Solana developer experience. It strengthens Solana’s reputation as a high-performance chain.

Part of Solana’s Growing Developer Stack

Helius introduced the API on paid plans in October 2025. The rollout reflects Solana’s broader tooling expansion. Infrastructure providers now compete on performance and usability. Solana benefits directly from this competition. Better tooling attracts more builders. More builders increase network activity. Early developer feedback has been positive. Many praised the clarity and speed of the API. Some called for open-sourcing the feature. Others suggested integrating it into Solana’s core RPC spec. These discussions show growing maturity in the ecosystem.

Why This Matters for Solana’s Future

Developer experience drives blockchain adoption. Solana already leads in throughput and cost efficiency. Tooling upgrades like this close the remaining gaps. Easier data access lowers the barrier to entry. Faster queries improve real-time applications. This API strengthens Solana’s position against competing Layer 1 chains. It also supports enterprise-grade use cases. As Solana scales, clean historical data becomes essential. Helius positions itself as a core infrastructure layer. Solana benefits from that alignment.
