RustCore Wallet

Self-custodial wallet for the Massa blockchain.

RustCore Wallet is a self-custodial wallet for the Massa blockchain. Your private keys are encrypted on your device with your password and never leave it. WHAT YOU CAN DO • Hold and send MAS and Massa tokens (USDC.e, WETH, DAI, WBTC and more), and add any custom MRC-20 token • Swap tokens through Dusa, with a minimum you'll accept • Buy and sell rolls to stake, with rewards and APR shown • See your .massa domains and register new ones • Several wallets in one place: create, import, rename and back up each one • Connect to Massa dApps and approve every request in the wallet's own window NEW IN 1.6.0: SEVERAL WALLETS PER SITE • When a site asks to connect, tick the wallets it may see — the one you're using comes ticked • The site follows the wallet you switch to, as in MetaMask • Home tells you when the site you're on is connected, but not to the wallet you're using • Settings → Connected sites: add or take away wallets for each site, or disconnect it • Older dApps stay on the wallet they show, so they can never ask you to sign from another one SECURITY & PRIVACY • Self-custodial: keys are encrypted locally (PBKDF2 + AES-GCM) and never sent anywhere • Every transaction has a review step; sites can never move funds without your approval • Auto-lock after 15 minutes; revealing a key, removing a wallet or logging out asks for your password again • No accounts, no analytics, no tracking, no RustCore servers. The wallet talks only to Massa's public nodes and the Massa explorer API • Source-available, with reproducible builds: anyone can check that this package is exactly what the source code says Popup, side panel and full-screen views.
