Harpie: The On-Chain Firewall

With the rise of memecoins and resurgence of DeFi, security on the blockchain is as important as it has ever been, however, most security solutions can be difficult to use or require a subscription.

Harpie presents a free-to-use, wallet agnostic security center that is currently available on Ethereum, Base, Arbitrum, and Polygon.

As the pace of the bull market continues to pick up, users often find themselves further out on the risk curve than before, and with increased activity comes increased risk. Monitoring wallet health and activity through a security solution like Harpie is one of the best steps you can take to protect yourself through exciting times in DeFi.

What Does Harpie Offer?

Harpie’s four primary features include comprehensive security overviews, 2-factor authentication, token protection, and approval revokes.

The security overview offers users a detailed evaluation of their wallet’s security status, providing a score based on potential vulnerabilities, and a breakdown of how to address them. This is similar to traditional web security software’s like Norton.

2-factor authentication, or 2FA, is one of the most important security measures to be taken in the crypto space. Harpie’s active security module allows users to route transactions through their “know your transaction” (KYT) engine. This system sends a 2FA request to users’ designated emails that includes detailed information on the transaction and its destination address.

Through Harpie’s token protection, their security module allows users to create custom whitelists of addresses and protocols that they trust, which can help prevent loss of funds through malicious redirects to spoofed websites.

Approval revoking, which is normally done through websites such as Revoke Cash, is made easier through Harpie’s interface, where users can get a complete view of any open contract approvals. These approvals can then be revoked directly in Harpie’s app.

Why Use Harpie?

Unlike independent, decentralized security solutions, Harpie is a US-based company that is required to abide by laws and regulations in the United States, and is backed by some of the most regulatory-friendly crypto investors in the world.

By working with Harpie’s app firsthand, users are able to go straight to the source for their security needs and evaluations. The security solution also uses traditional contact methods such as email to contact users whose assets may be under threat.
