SECURE YOUR DEVICE

Enter your 15-digit IMEI to generate a cryptographic hash stored on the Soroban ledger. Your actual IMEI never leaves your device.

Dial *#06# on your phone to find your IMEI. Must be exactly 15 digits.

What Gets Stored On-Chain
Enter IMEI to generate SHA-256 hash...

HOW THE PROTOCOL WORKS

A seamless lifecycle that flips the incentives of device theft.

01

Register

Your IMEI is hashed with SHA-256 and stored permanently on the Soroban ledger. Your device becomes a verifiable on-chain asset.

02

Report Stolen

If your device is stolen, trigger the killswitch. The contract locks the device asset and publishes a USDC bounty into escrow.

03

Bounty Posted

The USDC bounty is publicly visible on-chain. The device becomes economically worthless to resell but highly valuable to return.

04

Finder Paid

When the device is returned, the smart contract automatically releases the escrowed USDC to the finder. No trust required.

Economic Design

CHANGE THE INCENTIVES.
COLLAPSE THE MARKET.

In emerging markets, a stolen phone typically sells to a fence for $15–$40. By posting a trustless USDC bounty higher than the fence price, rational actors will choose to return the device rather than sell it.

We don't track devices. We manipulate the microeconomics of theft.

Bounty exceeds black market value — return becomes rational

Smart contract holds USDC in escrow — no counterparty risk

IMEI hash on-chain proves ownership — no dispute possible
