What is new

• ZIP-317 client-side fees (Zebrad has no estimatefee)
• nozy send --priority — opt-in fee ×4 (pilot, off by default)
• ~2-block expiry at build time (~2 minutes at 75s/block)
• nozywallet-api binaries included (HTTP companion on :3000)

Prerequisites (you run separately)

1. zebrad JSON-RPC (default http://127.0.0.1:8232)
2. lightwalletd gRPC for compact sync (default http://127.0.0.1:9067)

Use testnet first before mainnet. Walkthrough: docs/TESTNET_CLI_WALKTHROUGH.md

Quick start (CLI)

# Windows: download nozy-windows.exe, then in PowerShell:
.\nozy-windows.exe new
.\nozy-windows.exe scan --start-height <your_birthday_height>
.\nozy-windows.exe balance

# Standard send
.\nozy-windows.exe send -r <u1_address> -a 0.01 --testnet

# Dynamic-fee pilot: priority ×4
.\nozy-windows.exe send -r <u1_address> -a 0.01 --testnet --priority

Linux/macOS: chmod +x nozy-linux (or nozy-macos-*) and run ./nozy-linux with the same subcommands.

For @ShieldedLabs / pilot testers

Compare two sends with the same amount and shape: one without --priority, one with --priority. On-chain fee on the priority tx should be about 4× the standard ZIP-317 fee. Expiry height should be about chain tip + 2 at build time.

RFC: docs/rfcs/DYNAMIC_FEE_PILOT_PLAN.md

Not in v2.3.0

• Browser extension WASM priority sends (use CLI or build API from this release)
• Automatic Expired status / speed-up rebuild (Phase A1 follow-up on master)

Also in this repo

• Zeaking LWD smoke scripts, desktop app (separate release workflows may attach installers later)
