RustCore Wallet is now on the Chrome Web Store 🦀
Your Massa wallet as a browser extension: send, swap, stake and connect to dApps, with a review window before every signature.
One click to install, and it keeps itself up to date.

The wallet is free. Want to support our work? Mint a Core Keeper.
1,000 crabs · 700 MAS · 5 per wallet. The mint funds the wallet, the Launchpad and what comes next, and holding one takes 30% off every Launchpad fee.

⚠️ MAIN.5.1: Upgrade locked in!
More than 50% of the stake has now upgraded to MAIN.5.1, and the network upgrade is locked in.
🗓️ Activation: Monday, November 2, at 10:49:05 UTC
All node operators must update before activation. If your node is not updated by then, you risk forking from the rest of the network.
📖 Update guide: docs.massa.net/docs/node/upd…
📦 Massa Station: Update Massa Station first, then update your plugins.
⚙️ Node Manager: MAIN.5.1 is now available.
Please make sure your node is updated before activation to stay in sync with the network.
Thanks for helping keep Massa running smoothly! 🚀

📢 MAIN.5.1: New Node Version Released
A new Massa node version, MAIN.5.1, is now available:
github.com/massalabs/massa/r…
⚠️ Please update your node as soon as possible
This is a breaking update of the Massa node.
All node operators should update ahead of activation to ensure a smooth transition and avoid falling out of sync with the network.
🗓️ How does the upgrade work?
Lock-in: The upgrade is locked in once nodes representing at least 50% of the stake have updated to MAIN.5.1.
Activation: The upgrade activates one week after lock-in.
Please update your node as soon as possible, and no later than November 2, 10:00 UTC, to avoid forking from the rest of the network.
📖 How to update:
Follow the node update documentation :
docs.massa.net/docs/node/upd…
🛠️ For builders:
Some of these changes may affect your applications or integrations. Please review the list of breaking changes (github.com/massalabs/massa/p…) and check whether any updates are needed before activation.
We'll share the full changelog once the upgrade is activated.
Thanks for your cooperation! 🚀
RustCore Wallet 1.6 is out.
Connect several wallets to a site, as in MetaMask: it follows the wallet you switch to. Older dApps stay on the wallet they show.
Forgot your PIN or password? The lock screen now lets you start over.

RustCore Wallet 1.5 and Launchpad 1.3 are out.
Wallet: ready for Massa's MAIN.5.1 release, dApps can set the fee of transfers and rolls.
Launchpad: contract v1.3.1 live on mainnet after a 72-hour delay, with tokenomics and fixes from our internal audit.

RustCore Wallet 1.4.0 is out 🎉
🌐 Register your own .massa name, straight from the wallet.
NFTs → Domains → Register: type a name, see its price, confirm. Your wallet becomes the owner and the name points to your address.
👉 wrustcore.massa.network
Before you confirm, the wallet:
✅ checks on-chain that the name is still free
🧪 runs the registration as a test, so you only confirm one that would go through
💰 shows the exact price
Price (Massa Name System): 6+ chars 1 MAS · 5 → 10 · 4 → 100 · 3 → 1,000 · 2 → 10,000
RustCore takes no fee — you pay the Massa Name System, plus a 0.1 MAS storage deposit (the unused part comes back).
🛡️ Official address: wrustcore.massa. Never type your private key on a site sent to you.

Another project to explore on Massa DeWeb: @RustCoreMassa
The whole experience is served directly through DeWeb, with two main tools: RustCore Wallet and RustCore Launchpad.
The wallet supports staking, NFTs, MNS domains and Dusa swaps. The Launchpad handles MRC20 tokens, MRC721 collections, presales and an NFT marketplace.
We had a look through the code before sharing. It’s still a young project with no independent audit yet, so as always, DYOR.
Take a look around and explore what RustCore is building on Massa 👇

RustCore now lives on Massa's official DeWeb gateway 🎉
🔐 Wallet → wrustcore.massa.network
🚀 Launchpad → lrustcore.massa.network
🌐 Website → rustcore.massa.network
Same apps, still served straight from the Massa blockchain. 🧵
Used the wallet at the old address (wrustcore.deweb.half-red.net)?
Your browser keeps a wallet only where it was created, so it doesn't move by itself. Open the old address: it shows the steps. Back up your private key there, then import it at wrustcore.massa.network.
🛡️ Official addresses only: wrustcore.massa, lrustcore.massa, rustcore.massa.
Never type your private key on a site sent to you — RustCore never asks for it.
Code: github.com/RustCoreMassa
Community: t.me/rustcore_massa
The extension now locks with a password instead of a 6-digit PIN: stored browser data is a malware target, and a good password can't be guessed offline.
Already using it with a PIN? Unlock once and set a password. Your wallets stay as they are.
Stores are still reviewing the extension. Meanwhile, get it from GitHub (Chrome, Edge, Brave, Firefox):
github.com/RustCoreMassa/rus…
Support in Massa's wallet-provider is proposed, so dApps can list RustCore.
#Massa
⚠️ The only official addresses:
Wallet: wrustcore.massa
Launchpad: lrustcore.massa
Website: rustcore.massa
We will never DM you asking for funds, your PIN or your private key. Anyone who does is a scammer.
Next: dApp connection with per-site permissions in the extension, iOS & Android apps, and independent security audits.
