What Is Helius?
Helius is a developer infrastructure platform built exclusively for Solana. It simplifies blockchain development by offering ready-to-use APIs, fast RPC endpoints, and real-time data streaming, removing the need for teams to run or maintain their own nodes.
Think of Helius as the bridge between Solana’s raw blockchain data and your application’s backend. Instead of managing nodes, indexing data, or decoding transactions, developers connect to Helius’s APIs and start building immediately.
Core services include:
- RPC & API Access: High-performance, globally distributed endpoints for Solana mainnet and devnet.
- Data Streaming & Webhooks: Real-time tracking of transactions, NFT events, and account updates, powered by LaserStream, Helius’s low-latency gRPC data feed.
- On-Chain Indexing: Pre-decoded, developer-friendly APIs for quick access to Solana state and transaction data.
- Compression & Optimization Tools: Reduce data size and network overhead for faster throughput and lower costs.
- Validator & Staking Integration: Helius operates one of Solana’s most active validators with 0% commission, passing all staking rewards directly to delegators.
Because it’s purpose-built for Solana, Helius delivers unmatched speed, reliability, and data precision compared to generic multi-chain infrastructure providers.
How Helius Works
Helius operates a globally distributed network of Solana RPC nodes optimized for low latency, reliability, and scalability.
These nodes handle billions of requests per month, letting developers read and write Solana data through simple REST, RPC, or gRPC calls without managing infrastructure themselves.
RPC Infrastructure
- 99.99% uptime with automatic failover and geo-routing.
- Sub-100 ms latency for transaction and state queries.
- Dedicated or shared nodes available for different workloads.
- Integration with Solana’s Geyser plugin for real-time updates before block confirmation.
This setup lets developers build responsive applications that can stream or analyze live Solana data instantly.
Real-Time Webhooks & Event Streaming
Rather than polling the blockchain, Helius provides push-based updates via webhooks or LaserStream gRPC feeds.
Developers can subscribe to real-time notifications for:
- Token transfers and swaps
- NFT mints and burns
- Account or balance changes
- Program (smart-contract) invocations
This event-driven model is essential for DeFi dashboards, wallets, games, and bots that depend on instant blockchain awareness.
Compression & Performance Layers
Helius implements advanced data compression and indexing to minimize payload size and speed up delivery.
These optimizations reduce network overhead and storage costs, especially for large collections, historical queries, or state-heavy apps.
Validator & Staking Services
Helius operates one of the most active validators on Solana, providing:
- 0 % staking commission, with all rewards (including MEV) passed directly to delegators.
- SOC 2 Type II compliance and enterprise-grade uptime.
- Validator-as-a-Service options for institutions needing private, managed infrastructure.
This validator alignment gives Helius deep operational insight and a strong incentive to maintain Solana’s performance and security.
Why Developers Choose Helius

Real-Time Precision: Helius combines fast data ingestion and optimized transaction routing through services like LaserStream and Sender, enabling developers to react instantly to on-chain signals and achieve near-zero latency execution.
Ecosystem-Trusted: From wallets to trading platforms, Helius powers many of Solana’s leading projects, the invisible backbone behind real-time performance across the ecosystem.
Helius Ecosystem & Partnerships
Helius powers many of the flagship projects and tooling providers across the Solana ecosystem, from NFT marketplaces and wallets to DeFi protocols and analytics platforms.
It’s trusted by top builders such as Tensor, Backpack, Helium, and Jupiter, all of which leverage Helius’s RPC, APIs, or webhooks for fast, reliable access to real-time on-chain data.
- NFTs: Marketplaces like Tensor and Magic Eden use Helius endpoints for metadata indexing and mint event tracking, and compressed NFT support.
- Wallets: Backpack integrates Helius RPCs low-latency connectivity and smooth in-wallet user experiences.
- DeFi: Jupiter and Drift utilize Helius for real-time transaction data and liquidity routing.
- DePIN: Helium’s Solana migration uses Helius for block sync and event feeds.
By unifying RPC, data, and validator infrastructure, Helius serves as the AWS of Solana, a plug-and-play backend for scalable apps.
