What is yearn.finance?
Yearn Finance is a suite of products in Decentralized Finance (DeFi) that provides lending aggregation, yield generation, and insurance on the Ethereum blockchain. The protocol is maintained by various independent developers and is governed by YFI holders. It started out as a passion project by Andre Cronje to automate the process of switching capital between lending platforms in search of the best yield offered, as the lending yield is a floating rate rather than fixed rate. Funds are shifted between dYdX, AAVE, and Compound automatically as interest rates change between these protocols. ...

Frequently Asked Questions
How does Burner Work?
Burner is a complete yearn.finance 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 YFI balances. To send YFI, just use BurnerOS to prepare the transaction and tap your Burner when prompted.
How secure is Burner?
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.
Can I use Burner offline?
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.
Who built Burner?
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 YFI without the need for a dedicated app or backend services.
If there is no seed phrase how can I back up Burner?
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.
How is Burner different from other wallets?
Burner is designed to make gifting YFI 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.
Does Burner support yearn.finance?
Yes, Burner supports yearn.finance (YFI) on the optimism network. You can store, send, and gift YFI securely using Burner's NFC hardware wallet.
What happens if Burner is no longer supported?
If for any reason BurnerOS stops working or is blocked in certain jurisdictions you can always interface with Burner through our open source libraries.
