Crate zecscope_scanner 

zecscope-scanner

High-level Zcash shielded transaction scanner for viewing keys.

This crate provides a simple API to scan Zcash compact blocks using Unified Full Viewing Keys (UFVKs) and discover incoming shielded transactions in both the Sapling and Orchard pools.

Features

• Simple API: Just provide a UFVK and compact blocks, get transactions
• Sapling + Orchard: Scans both shielded pools (Orchard requires orchard feature)
• WASM-compatible: Use in browsers via WebAssembly (enable wasm feature)
• Serde support: All types serialize/deserialize for easy JSON interop

Example

use zecscope_scanner::{Scanner, ScanRequest, Network};

// Create a scanner for mainnet
let scanner = Scanner::new(Network::Mainnet);

// Scan blocks with a viewing key
let request = ScanRequest {
    viewing_key: "uview1...".to_string(),
    key_id: "my-wallet".to_string(),
    compact_blocks: blocks, // Vec<CompactBlock>
};

let transactions = scanner.scan(&request)?;

for tx in transactions {
    println!("{}: {} ZEC ({})", tx.txid, tx.amount_zec(), tx.pool);
}
