Frequently asked questions

How can Harpie "outbid a transaction?"

Every transaction on Ethereum takes a small amount of time to process. In that time, another party can "outbid" the transaction, meaning that they can have their transaction execute first. Our technology outbids malicious transactions and transfers balances to a user-owned "safe haven" wallet before a theft happens.

What is the definition of a malicious transaction?

By default, we define all transactions as malicious. Users have an address book where they can approve addresses as safe addresses. Transactions to safe addresses are not detected as malicious.

How does Harpie detect malicious transactions?

We have multiple nodes and providers querying the blockchain hundreds of times a second. Malicious transactions are detected and eliminated before they are confirmed on the blockchain.

Is Harpie a wallet?

No, Harpie is not a wallet. We're a smart contract-based protocol that is designed to work with users no matter what wallet they're on.

Do I have to give you my seed phrase?

NO. We never ask for your seed phrase or store your private keys. All of our services are provided securely through smart contracts.
