QuickNode: Solana gRPC plus Carbon program decode logoQuickNode: Solana gRPC plus Carbon program decode
gRPC stream in. Carbon decodes the instruction. You write the processor.
devrels.xyz/a/346QuickNode Solana gRPC is Yellowstone-compatible Geyser streaming: accounts, transactions, slots. This guide wires that stream into Carbon, a Rust indexing pipeline (datasource, decoder, processor). Live write-up: Solana gRPC and Carbon (7 Aug 2026). X @QuickNode. LinkedIn company/quicknode. Yellowstone overview stays: Yellowstone gRPC.
Access: Scale or Business, or the Solana gRPC add-on on Build and Accelerate. Local env: GEYSER_URL and X_TOKEN. Never commit the token. Guide crates (0.8.0): carbon-core, carbon-yellowstone-grpc-datasource, carbon-pumpfun-decoder, yellowstone-grpc-proto 5.0.0, tokio 1.43.
[dependencies]
carbon-core = "0.8.0"
carbon-yellowstone-grpc-datasource = "0.8.0"

yellowstone-grpc-proto = "5.0.0"
tokio = { version = "1.43.0", features = ["full"] }Carbon pieces: Pipeline, datasources, pipes, decoders, processors. The worked example filters Pump.fun for new mints and AMM migrations. Same shape for other crates in the guide list (Jupiter, Raydium, Meteora, Orca, Token-2022, MPL Core, and more). Check Carbon docs for the live decoder set.

Point a Yellowstone client at a LaserStream region, pass the API key, subscribe. Helius runs the nodes, replay, and failover.
If you've ever missed a websocket update or polled getProgramAccounts in a loop, this is the fix. Yellowstone gRPC taps Solana's Geyser interface and streams filtered account/tx/slot/block updates over HTTP/2 — lower latency, server-side filtering, real backpressure. The data layer indexers actually use.
