Enhanced Streams

Enhanced Streams publish selected Solana events through a server-streaming gRPC service.

Download the service proto

bash
curl -O https://cubestech.online/protos/enhanced-streams.proto

The service endpoint is:

text
streams.sol.cubestech.online:443:443

List your topics

Topic access depends on your plan.

bash
grpcurl \
  -H "x-api-key: YOUR_API_KEY" \
  -import-path . \
  -proto enhanced-streams.proto \
  -d '{}' \
  streams.sol.cubestech.online:443:443 \
  nln.stream.v1.StreamService/ListTopics

Subscribe to swaps

bash
grpcurl \
  -H "x-api-key: YOUR_API_KEY" \
  -import-path . \
  -proto enhanced-streams.proto \
  -d '{"topic":"prod.rpc.solana.program.swaps-partitionless","format":"JSON"}' \
  streams.sol.cubestech.online:443:443 \
  nln.stream.v1.StreamService/Subscribe

Each response carries:

  • topic
  • partition
  • offset
  • timestampMs
  • payload

For JSON output, payload holds UTF-8 JSON bytes. Decode the bytes once.

Do not base64-decode payload after your protobuf library returns a byte array. Convert the byte array to UTF-8 text, then parse JSON.

Solana Enhanced Streams

Choose decoded real-time feeds for swaps, lifecycle events, transfers, and system activity.
