Solana Yellowstone gRPC Streaming on FluxRPC
FluxRPC provides managed Yellowstone gRPC streaming for Solana mainnet. Receive filtered account updates, transactions, blocks and slots for trading applications, wallet monitoring and indexers without operating your own streaming infrastructure.
Mainnet Yellowstone, Solana RPC and WebSockets are included on the regular $38/month Developer plan, with 250 GB of shared bandwidth. Use your included allowance first, then purchase additional bandwidth at $6 per 100 GB or upgrade. There is no separate Yellowstone subscription to add.
What is Yellowstone?
Yellowstone is a Geyser plugin that streams real-time blockchain data from Solana validators. Unlike traditional REST APIs that require polling, Yellowstone establishes persistent bidirectional connections that push data to your application as it happens on-chain.
This streaming approach is ideal for building DEX aggregators, wallet monitoring systems, NFT marketplaces, analytics platforms, and any application requiring immediate access to blockchain state changes.
