Web3 Keys Don't Belong in the Cloud. Here's a Better Way.

Multi-Party Computation (MPC) is a game-changer for Web3 security. It eliminates the single point of failure of a traditional private key by splitting it into multiple pieces, or "shards." But it introduces a new, critical question: where do you back up those shards?

For many Web3 infrastructure companies, the default answer is the cloud. 

It's easy, familiar, and automatic. But convenience can be a dangerous tradeoff when it comes to securing your digital assets.

The Myth of "Secure" Cloud Backups

We’ve all seen the headlines: massive data breaches, accounts hacked, and sensitive documents leaked from the very cloud services we're told to trust. While these platforms use encryption, they share a fundamental vulnerability: they are always online.

These online backups are constantly available remote targets.

It's time for a more secure offline backup solution to your Web3 infrastructure than cloud storage backups for MPC shards.

The Smart Solution: Dumb NFC Tags

The best way to protect your key shards is to take them completely offline. This is where a simple, "dumb" NFC tag becomes the simplest tool for the job.

An NFC tag is a small, passive chip that requires no power and has no internet connection. Think of it as a digital version of a piece of paper. Its simplicity is its greatest strength. An NFC tag can't be hacked remotely because it's not connected to the internet so to access the data on it, you need physical possession of the tag itself(or to be within a few feet of it and a professional hacker).

This creates a true air-gapped backup.

Offline by Default: No Wi-Fi, no cellular radio, and no online account associated with it. It’s a digital island.

Simple & Intuitive: The user experience is dead simple. Tap your phone to the tag to back up the shard. Then, put the tag somewhere safe—a drawer, a safe, or a safety deposit box.

User-Controlled: You, and only you, hold the physical backup. You are not dependent on a third-party corporation's security practices or the integrity of their employees.

While cloud storage is fantastic for vacation photos and work documents, it is fundamentally the wrong security model for the keys to your digital life. For something as critical as an MPC shard, you need to eliminate remote threats entirely. By moving your backup from the ever-present risk of the cloud to the physical security of a physical device, you take back control and give your assets the offline protection they deserve.
