Frequently Asked Questions
Burner is an affordable, credit-card-sized hardware wallet built for gifting and everyday crypto use. It uses the same secure chip technology found in traditional hardware wallets like Ledger or Trezor, but reimagines the hardware wallet experience with a seedless design, web-based interface, and NFC connectivity. Burner combines the security of cold storage with the convenience of a software wallet, offering an accessible self-custody solution for spending, saving, and gifting crypto securely.

OpenBurner is an open-source Web3 wallet designed specifically for Burner Ethereum hardware wallets. Use your Burner across Ethereum, Base, BNB Chain, Arbitrum, Avalanche, Blast, Linea, Mantle, Mode, Optimism, Polygon, Scroll, Unichain, and any custom EVM chain you configure.
Yes! The hosted version at app.openburner.xyz works on mobile devices. You can use your smartphone as the NFC reader directly - no USB reader required. The local version also supports using your smartphone as an NFC reader, or you can use a USB NFC reader with a desktop browser.
Yes, OpenBurner requires a Burner hardware wallet. The card contains a secure element that stores your private keys, which never leave the hardware. You can get a Burner Ethereum here.
You'll need a USB NFC reader. I recommend the ACS ACR122U, which works well with both Windows and macOS. Other NFC readers might work, but this one is tested and reliable.
BurnerOS is the official wallet app from Burner. It supports Ethereum, Base, Arbitrum, and Optimism. OpenBurner supports those same chains plus many more (including BNB Chain, Avalanche, Blast, Linea, Mantle, Mode, Polygon, Scroll, and Unichain), and lets you add any custom EVM-compatible chain. It runs locally on your machine and gives you full control over which RPC endpoints you use.
Yes. Your private keys never leave the Burner card's secure element. All signing happens on the hardware. OpenBurner uses the same LibBurner and LibHalo libraries as BurnerOS and simply requests signatures when needed. The code is open source and can be audited by anyone.
No. Neither the hosted nor local version of OpenBurner collects, stores, or transmits any personal data, wallet addresses, or transaction information. When using gateway connection, OpenBurner uses the same hosted gateway that Burner uses, which uses a secure WebSocket with end-to-end encryption and stores no data on the gateway server. All blockchain interactions happen directly between your browser and the RPC endpoints you configure.
No. OpenBurner focuses on managing fungible tokens like ERC-20s and native chain tokens for DeFi and everyday transactions.
OpenBurner doesn't use a token list service, so you'll need to manually add any tokens you want to see. Any tokens you add are stored in your browser's local storage.
Absolutely. If you already have a Burner card set up with BurnerOS, you can use the same card with OpenBurner. Your addresses and keys remain the same across both applications.
It's pretty straightforward. Check the docs for instructions on adding custom networks.
Yes. OpenBurner is MIT licensed. You can view the code, modify it, and fork it for your own use on GitHub.
OpenBurner uses ethers.js for blockchain interactions, LibBurner and LibHalo for hardware wallet communication, Multicall3 for efficient batch RPC calls, and the CoinGecko API for real-time token prices.
You have two options: Hosted version - Visit app.openburner.xyz in your browser (works on mobile and desktop, uses your smartphone as NFC reader). Local version - Run it on your machine with a desktop browser, using either your smartphone as NFC reader or a USB NFC reader.
Yes! OpenBurner is now available online at app.openburner.xyz. No installation required - just visit the site in your browser and use your smartphone as the NFC reader.
