Examples

• Display available methods: ./toGRPCurl.sh describe

• Display latest block: ./toGRPCurl.sh GetLatestBlock

• Grab a particular block and display available transaction hashes: ./toGRPCurl.sh GetBlock 2986174 | jq .vtx[].hash

  • note: requires jq for nice formatting

• Convert a serialized lightserver transaction hash into its txid (viewable on an explorer )

  • ./base642hex wMSYjN52F1F63UmVaSaZx4GAZgaDRpL1K4pUKlvTfHw=
  • ./byteFlippedHex.sh c0c4988cde7617517add4995692699c781806606834692f52b8a542a5bd37c7c

• Convert a serialized lightserver transaction hash into a useable JSON

  • ./toGRPCurl.sh GetTransaction wMSYjN52F1F63UmVaSaZx4GAZgaDRpL1K4pUKlvTfHw= | jq .data > myBase64txid

-   `cat myBase64txid | xargs ./base642hex > myrawtxid`-   `cat myrawtxid | xargs zcash-cli decoderawtransaction`
