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 The Graph, and other cryptocurrencies.
Unlike software wallets that expose your private keys to online threats, Burner uses a secure chip with PIN protection. No seed phrases to write down, lose, or have stolen by phishing attacks.

Gifting The Graph is surprisingly difficult with traditional methods—recipients need to set up wallets, manage seed phrases, and navigate complex interfaces. Burner makes it simple: load and hand over the card.
The simple, secure hardware walletfor storing GRT and all your crypto.

The Graph is an indexing protocol and global API for organizing blockchain data and making it easily accessible with GraphQL. Developers can use Graph Explorer to search, find, and publish all the public data they need to build decentralized applications. The Graph Network makes it possible to build serverless dApps that run entirely on public infrastructure. GRT is the native token of the network that’s used to coordinate work. GRT is an ERC20 token. Node operators, called Indexers, stake and earn GRT for processing queries. Anyone can delegate GRT to Indexers to secure the network and ear...
Burner is a complete The Graph hardware wallet that works with your smartphone's NFC connection and web browser through the BurnerOS web app—no installation required. BurnerOS allows you to generate private keys, sign transactions, and check your GRT balances. To send GRT, just use BurnerOS to prepare the transaction and tap your Burner when prompted.
Burner uses the same secure element chip technology found in more expensive hardware wallets. It generates keys from hardware-based randomness and extra entropy that you provide. Requests to sign transactions are PIN-code protected, and Burner will permanently lock after 20 failed attempts. If you receive a Burner as a gift, you can verify whether or not its key has ever been used to sign a message.
Yes, we offer open source libraries to interact with Burner at a low level. These libraries can be used with smartphone web apps, dedicated apps and command line interfaces. They also work with desktop PCs and hardwired NFC readers meaning you can use a fully offline desktop computer to interface with Burner for the highest security.
Burner was created by the team behind Offline Cash, a physical Bitcoin banknote that used secure NFC chips linked to physical paper notes for storing and gifting crypto. Unlike Offline Cash, Burner is more resilient and capable, allowing the gifter to send any amount of GRT without the need for a dedicated app or backend services.
BurnerOS includes a Card Duplicator tool that can be used to backup one Burner to another. You can also verify whether a gifted Burner has been duplicated or is itself a duplicate.
Burner is designed to make gifting GRT easy without sacrificing simplicity or security. Unlike QR codes or seed phrases that require technical knowledge and external apps, Burner is immediately usable by the recipient through our simple BurnerOS web app. Compared to traditional hardware wallets, Burner has no steep learning curve; simply tap it to your phone and you're ready to go.
Yes, Burner supports The Graph (GRT) on the arbitrum network. You can store, send, and gift GRT securely using Burner's NFC hardware wallet.
If for any reason BurnerOS stops working or is blocked in certain jurisdictions you can always interface with Burner through our open source libraries.
