GRAPE DESKTOP 0.4.4 — TESTNET 23 October 2026 Network: Grape testnet Chain ID: 4727386 RPC: https://rpc.grap3.com Genesis: 0x77db4905d3bb493d344c542c79fcf26b2dfd5cf880e624bafa5a42b5cb6e0242 Desktop source: 862fba0ad2c3185554fe8b776bdaeb7b8a0d8884 Bundled Mac/Linux node source: 3195d40c7798aa1bbf21d945f7bb7c41418cd22f WINDOWS — x64, Windows 10 or newer Run grape-desktop-windows-amd64.exe for the per-user installer, or extract the ZIP into a folder and open Grape.exe. This release includes the wallet and bundled Grape apps. It keeps signing keys on the PC and connects to the pinned Grape testnet RPC. A local full node or validator is not included, and opening this wallet does not earn node rewards. Windows node support will be a separate release. This installer is unsigned. Package integrity and the shared wallet core have been verified; native Windows installation and interactive Windows acceptance have not yet been completed. LINUX — x64, Ubuntu 22.04 or compatible newer distribution Allow grape-desktop-linux-amd64.AppImage to execute, then open it. AppImages need FUSE 2 (libfuse2 on Ubuntu 22.04, libfuse2t64 on newer distributions). Alternatively extract the tar.gz and open grape-desktop from its folder. The package contains the wallet, Grape apps, full node and protected validator helper. Grow guides setup; the system asks for administrator approval when installing validator services. A bond requires a separate transaction review and your PIN. Registration alone does not establish activation or rewards. The native package was launched under a Linux virtual display; its bundled full node joined and synchronized with the current testnet. No funded validator bond or production-security acceptance is claimed by these checks. Linux ARM64 is not included in this release. MAC — Apple Silicon, macOS 13 or newer Open the DMG and drag Grape to Applications, or use the ZIP. The wallet, Grape apps, full node and guided validator setup are included. The app is ad-hoc development-signed, not Apple-notarized. Intel Mac is not included. WHAT IS INCLUDED - Private-key import with a device password, or encrypted-backup restore. - New wallets offer a deliberate private-key backup screen. - Six-digit PIN approvals; keys stay in the local signer. - Daxly, Circle, collectibles, explorer, domains, governance, faucet and the testnet liquidity preview through the bundled wallet interface. - The download page describes each platform's current capabilities. - A native asset-route fix keeps the backup screen's module reachable. Online balances, transactions and hosted apps require an internet connection. A Daxly or Circle sign-in does not recover or transfer wallet keys. Existing Daxly accounts retain their login and credit system. Keep wallet backups private and secure. Test GRP has no monetary value. VERIFY SHA256SUMS.txt contains the SHA-256 digest for each downloadable package. Keep operating-system security protections enabled. These are development packages for the current testnet, not a mainnet or funded-use qualification.
