Create fully signed shielded TRX transactions client-side. Public TRON nodes generally do not expose an RPC for wallet/createshieldedtransaction; attempting to POST to that route returns HTTP 405. Build shielded transactions locally using TRON shielded transaction libraries.

​
Parameters

  • transparent_from_address — the transparent TRX address sending funds (optional)
  • from_amount — the amount to send from transparent address (in sun)
  • spend_authority_signature — array of spending authority signatures for shielded inputs
  • ask — authentication secret key for transaction signing
  • nsk — nullifier secret key for creating nullifiers
  • ovk — outgoing viewing key for transaction encryption
  • to_address — recipient shielded address
  • to_amount — amount to send to shielded address (in sun)

​
Response

  • txID — the transaction ID hash
  • raw_data_hex — the raw transaction data in hexadecimal format
  • raw_data — the structured raw transaction data

​
Use case

The wallet/createshieldedtransaction method is used for:
  • Creating fully signed shielded TRX transactions for immediate broadcast
  • Transferring TRX between transparent and shielded addresses
  • Supporting complete privacy-preserving TRX transactions
  • Enabling applications to create ready-to-broadcast shielded transactions

​
Client-side implementation

Public nodes typically return HTTP 405 for this route. Build shielded transactions client-side using TRON privacy libraries (e.g., tronweb with shielded support) or Sapling-compatible implementations. Generate and sign the transaction locally, then broadcast via wallet/broadcasttransaction.
Use TRON’s shielded transaction libraries to:
  1. Construct the shielded inputs (spends) and outputs (receives) using your key material (ask, nsk, ovk)
  2. Generate the zero-knowledge proof parameters offline
  3. Sign the transaction with spending authority signatures
  4. Build the complete signed raw transaction structure
  5. Broadcast the transaction via wallet/broadcasttransaction
