​
Parameters

  • output_point — the output point for the merkle tree voucher
  • ak — the authentication key for the voucher
  • nk — the nullifier key for the voucher
  • position — position in the merkle tree

​
Response

Returns merkle tree voucher information containing:
  • voucher_info — the voucher information object
  • paths — array of merkle tree path elements for cryptographic verification
  • anchors — array of anchor values for the merkle tree
  • rt — merkle tree root
  • output_point_info — detailed information about the output point

​
Use case

The wallet/getmerkletreevoucherinfo method is used for:
  • Generating cryptographic proofs for shielded transactions in TRON privacy features.
  • Verifying transaction authenticity using merkle tree structures.
  • Building privacy-preserving applications that require zero-knowledge proofs.
  • Implementing advanced cryptographic verification systems on TRON network.
