Generate a shielded payment address locally from an incoming viewing key (ivk) and a diversifier (d). TRON nodes typically do not expose an RPC for this; derive on the client using a Sapling library and then use the address to receive shielded TRC20 payments.

​
Inputs

  • ivk — incoming viewing key as a 32‑byte (64‑hex) string, no 0x prefix.
  • d — diversifier as 11 bytes (22 hex), no 0x prefix.

​
Outputs

  • pkd — payment address public key in hexadecimal format (no 0x).
  • payment_address — the complete shielded payment address.

​
Use case

The wallet/getshieldedpaymentaddress method is used for:
  • Generating shielded addresses to receive private TRC20 payments
  • Creating diversified payment addresses from viewing keys and diversifiers
  • Supporting wallet implementations that need to generate receiving addresses
  • Enabling privacy-preserving transaction receiving capabilities

​
How it works (Sapling)

  1. Parse ivk (32 bytes) and d (11 bytes) from hex.
  2. Compute g_d = diversifyHash(d) (Jubjub point derived from the diversifier).
  3. Compute pkd = ivk · g_d (scalar multiplication on Jubjub).
  4. Encode (d, pkd) into a TRON Sapling payment address (Bech32 with HRP ztron).
Use a Sapling implementation (Rust/WASM or native). Do not implement the primitives yourself.

​
Example (JavaScript, WASM Sapling)

// Pseudocode — use a Sapling/Jubjub library that exposes diversifyHash and scalarMul
import { diversifyHash, scalarMul, bech32mEncode } from 'sapling-lib';

const ivkHex = '0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef';
const dHex   = '06a1b2c3d4e5f6789012ab';

const ivk = Buffer.from(ivkHex, 'hex');        // 32 bytes
const d   = Buffer.from(dHex, 'hex');          // 11 bytes

const gd  = diversifyHash(d);                  // Jubjub point
const pkd = scalarMul(ivk, gd);                // 32‑byte compressed point

// payment address = Bech32m("ztron", d || pkd)
const payload = Buffer.concat([d, pkd]);
const paymentAddress = bech32mEncode('ztron', payload);

console.log({ pkd: pkd.toString('hex'), paymentAddress });

​
Example (Python, Rust FFI/WASM)

# Pseudocode — use a Sapling library (e.g., librustzcash bindings) that exposes diversify_hash and scalar multiplication
from sapling import diversify_hash, scalar_mul, bech32m_encode

ivk_hex = '0123456789abcdef0123456789abcdef0123456789abcdef0123456789abcdef'
d_hex   = '06a1b2c3d4e5f6789012ab'

ivk = bytes.fromhex(ivk_hex)
d   = bytes.fromhex(d_hex)

g_d = diversify_hash(d)
pkd = scalar_mul(ivk, g_d)

payload = d + pkd
payment_address = bech32m_encode('ztron', payload)

print({'pkd': pkd.hex(), 'payment_address': payment_address})
  • Exact lengths: ivk = 64 hex (32 bytes), d = 22 hex (11 bytes). No 0x prefix.
  • Use a maintained Sapling library (Rust → WASM/FFI). The node does not provide this derivation.
