Overview
Burner (opens in a new tab) is a product offered by Arx that is built on top of HaLo technology. It is a full hardware wallet that can store tokens and sign messages. Burner is typically accessed by users via a browser web app called BurnerOS. BurnerOS leverages libHaLo at a low level to interact with Burner cards.
BurnerOS also uses libBurner (opens in a new tab), a higher level library that provides "wallet like" functionality, such as managing expected Burner key slots, signing messages that conform to EIP-712 and EIP-191 specifications and integrating with libraries like viem (opens in a new tab) as a wallet provider.
You can interface with Burners using either libHaLo or libBurner, depending on your needs. If you want to interact with the low-level features of the Burner card, such as reading and writing data, you can use libHaLo. If you want to use the higher-level wallet functionality, such as signing messages and managing keys, we recommend libBurner.
