- **Real-time Event Streaming**: Subscribe to live trading events from multiple Solana DEX protocols
- **SDK-backed Parser Core**: Transaction, RPC, account, and ShredStream parsing are backed by `sol-parser-sdk`
- **Yellowstone gRPC Support**: High-performance event subscription using Yellowstone gRPC
- **ShredStream Support**: Alternative event streaming using ShredStream protocol
- **ShredStream Support**: Alternative event streaming using ShredStream protocol; ALT-loaded accounts are parsed best-effort with default account placeholders

### Use crates.io
```toml
# Add to your Cargo.toml
solana-streamer-sdk = "1.5.0"
solana-streamer-sdk = "1.5.1"
```
Parser backend features:
```toml
# Default: sol-parser-sdk parse-borsh backend
solana-streamer-sdk = "1.5.0"
solana-streamer-sdk = "1.5.1"
# Zero-copy parser backend for latency-sensitive bots
solana-streamer-sdk = { version = "1.5.0", default-features = false, features = ["sdk-parse-zero-copy"] }
solana-streamer-sdk = { version = "1.5.1", default-features = false, features = ["sdk-parse-zero-copy"] }
```
If both `sdk-parse-borsh` and `sdk-parse-zero-copy` are enabled, `sol-parser-sdk 0.5.0+` uses the zero-copy backend.
If both `sdk-parse-borsh` and `sdk-parse-zero-copy` are enabled, `sol-parser-sdk 0.5.1+` uses the zero-copy backend.
## 🔄 Migration Guide
### Upgrading to v1.5.1
Version 1.5.1 uses `sol-parser-sdk 0.5.1` from crates.io. It improves ShredStream ALT handling by parsing outer instructions best-effort with default placeholders for ALT-loaded accounts, adds dropped-event queue observability, and keeps CPI/inner-only events documented as a ShredStream limitation.
### Upgrading to v1.5.0
Version 1.5.0 uses `sol-parser-sdk 0.5.0`, wires Raydium CLMM account parsing through the SDK bridge, and reduces ordered-buffer allocation/move overhead in low-latency delivery paths. `sol-parser-sdk 0.4.19` and `solana-streamer-sdk 1.4.14` were superseded because adding public parser event variants belongs in the 0.5 line.
