The Starknet Foundation has released Bramble, a browser wallet that runs only on Chrome and bundles private balances with Ledger hardware signing and multisig accounts. The wallet also supports STRK20 shielding, which lets users move STRK20 tokens into a private balance.
Bramble ships with a recovery phrase for backup. That's the standard seed-phrase model, not a social-recovery or MPC setup, so losing the phrase means losing access to the wallet.
What Bramble actually does
Bramble isn't a general-purpose wallet. It's a Chrome extension, and the foundation hasn't announced versions for Firefox, Safari, Brave, or mobile browsers. If you're on anything other than Chrome, you can't install it.
The feature set is narrow but specific. Private balances let users hold and transact without exposing amounts or counterparties on-chain in the same way public balances do. Ledger signing means transactions can be approved on a hardware device rather than in the browser alone. Multisig accounts let more than one key approve a transaction before it goes through.
STRK20 shielding is the piece tied most directly to Starknet's own token work. Shielding moves STRK20 into a private state, and Bramble is the first wallet from the foundation to support it directly.
The Chrome-only trade-off
Limiting Bramble to Chrome keeps the build small and the testing surface tight. It also narrows the audience. Chrome is the most widely used desktop browser, but wallet users are a fragmented group, and a meaningful share of them run Firefox or use mobile devices as their primary wallet environment.
The foundation hasn't said whether other browsers are on the roadmap. For now, the Chrome restriction is the first thing users will hit when they try to install it.
Recovery phrase and key management
Bramble's backup model is a recovery phrase, the same 12- or 24-word format used across most self-custody wallets. That's familiar to experienced users and risky for newcomers, who are the group most likely to store the phrase in a screenshot or a notes app.
Pairing the phrase with Ledger signing gives users a second path: keys can stay on the hardware device, and the browser wallet approves what the device signs. Multisig adds a third layer for accounts that need more than one approver.
The combination is unusual for a foundation-built wallet. Most wallet releases from protocol foundations lean toward simplicity. Bramble leans toward configurability, which fits accounts managing treasury or shared funds more than it fits a first-time user buying a small amount of STRK20.
What's missing from the launch
The foundation hasn't published a support timeline for other browsers, a mobile app, or a hardware wallet other than Ledger. There's also no word on whether Bramble will support tokens beyond STRK20, or whether shielding will extend to other assets on Starknet.
For developers and multisig signers already on Starknet, Bramble is available now through Chrome. For everyone else, the install page is the place to watch.
