Helius

Solana RPC Nodes

Helius provides enhanced Solana RPC services that include both public and private nodes. These nodes are optimized to deliver high throughput and low latency, ensuring efficient transaction handling on Solana’s high-performance blockchain. Helius also offers private and dedicated RPC nodes for projects that require exclusive access to RPC infrastructure. Additionally, the platform introduces an RPC proxy feature, which allows developers to protect their keys when sending transactions.

Priority Fee API

Helius’ Priority Fee API is designed to optimize transaction fees on Solana. This API ensures that transactions are processed efficiently by dynamically adjusting fees according to network congestion. This service is essential for developers building time-sensitive applications, as it guarantees faster transaction processing in competitive environments.

cNFT Compression and Digital Asset Standards (DAS)

Helius leverages compressed NFTs (cNFTs) to significantly reduce the cost of minting and managing non-fungible tokens (NFTs) on Solana. The platform uses zk-compression, a zero-knowledge compression method that reduces the storage and data transfer costs associated with NFTs. By introducing Digital Asset Standards (DAS), Helius allows for more efficient management of digital assets on Solana, setting the foundation for mass scalability of NFTs and other tokenized assets.

Webhooks and WebSockets

Helius offers enhanced WebSockets and real-time webhook notifications to streamline monitoring blockchain events, such as transactions, balance changes, and token metadata updates. These services allow developers to integrate real-time data feeds into their applications, ensuring up-to-the-second accuracy for dApps that rely on frequent updates. With their gRPC Yellowstone service, Helius ensures fast and reliable data delivery for all types of blockchain events.

APIs for Solana

Helius provides a set of specialized APIs to simplify interactions with the Solana blockchain. These include the Enhanced Transactions API, which allows developers to track detailed transaction data; the Token Metadata API, which provides token-related information; and the Token Balances API, which tracks balances across different Solana wallets. These APIs streamline token management, ensuring that developers have easy access to comprehensive blockchain data.

Usage and Applications

Helius’ infrastructure supports a wide range of blockchain applications, including decentralized finance (DeFi), gaming, and NFT marketplaces. By offering reliable node services, compression technologies, and real-time event tracking, Helius empowers developers to build scalable decentralized applications on Solana. The platform’s focus on cost reduction through compression and efficient fee management makes it particularly attractive for projects handling large-scale digital assets, such as NFT collections and high-frequency trading platforms.

Pricing and Rate Limits

Helius operates on a tiered pricing structure, providing flexibility for developers of different sizes and needs. Pricing plans are based on API usage, with specific rate limits for transactions and API calls. For developers who need higher throughput or private access to infrastructure, dedicated node services are available.

Security and Audits

Helius takes security seriously, offering measures like private dedicated nodes and secure transaction routing through RPC proxies. The platform ensures that all services are regularly audited to maintain the highest standards of security for developers and users. Additionally, Helius encourages security through a bug bounty program, where developers can report vulnerabilities.
