TRON API method that creates parameters for a shielded TRC20 contract transaction without requiring the authentication secret key (ask). This simplified version is used when the ask is not available or needed for the specific transaction type.

This endpoint requires valid shielded addresses and cryptographic material. All parameters must be properly formatted: shielded addresses must be valid ztron1 addresses, the outgoing viewing key must be a valid 0x-prefixed hex string, and optional transparent addresses must be valid TRON addresses (starting with T). Invalid or placeholder values will result in parsing errors.

​
Parameters

  • ovk — the outgoing viewing key for transaction monitoring (0x-prefixed hex string)
  • from_address — the sender’s shielded address (ztron1 format)
  • to_address — the recipient’s shielded address (ztron1 format)
  • amount — the amount to transfer (in sun, as string)
  • transparent_from_address — optional transparent sender address (T-address format)
  • transparent_to_address — optional transparent recipient address (T-address format)

​
Response

  • receive_description — the receive description for the shielded transaction
  • spend_description — the spend description for the shielded transaction
  • binding_signature — the binding signature that ties the transaction together

​
Use case

The wallet/createshieldedcontractparameterswithoutask method is used for:
  • Creating shielded transaction parameters without access to authentication secret keys
  • Generating transaction data for view-only or monitoring applications
  • Supporting simplified wallet implementations that don’t store sensitive key material
  • Enabling third-party services to prepare shielded transactions with limited key access
