The decentralized application for secure file sharing and ephemeral messaging. No servers, no tracking. Just you and your data.

Client-side execution. Keys never leave device.
In an age of surveillance capitalism, privacy is no longer a luxury, it's a necessity. Shield is a decentralized application that ensures your files and messages remain yours alone.
We employ client-side Zero-Knowledge architectures to process transactions. Your keys are generated in your browser and never hit a server, ensuring that even we cannot access your data.
Browser-Based Security
"Your data is encrypted before it ever leaves your browser window. The decryption key is generated locally and shared only via the link you control."
Built on decentralized storage layers ensuring redundancy and censorship resistance.
Just connect your web3 wallet.
Shield coordinates a simple, wallet-gated flow between sender and receiver. Every link is bound to a specific EVM-compatible address and time-limited for safety.
Upload
Add the content you want to share — either a file or an encrypted text message — directly in your browser.
Recipient wallet
Provide the receiver’s EVM-compatible wallet address. The link will only decrypt for this exact address.
Access limits
Choose how long the link should stay valid (in seconds) and how many times the content can be opened before it expires.
Generate link
Hit the Generate Link button, sign the transaction in your connected wallet, and let Shield encrypt and register the share.
Once confirmed, copy the share link and send it to the intended receiver through any channel you prefer.
Open & connect
Open the shared link and connect your wallet in the Shield interface using any supported EVM-compatible wallet.
Verify ownership
Click the Verify Wallet Ownership button and approve a gasless signature (followed by a transaction) request in your connected wallet.
Shield checks that the connected wallet matches the address chosen by the sender. If it matches and the link is still valid, the encrypted content is unlocked for you.
Access content
View the decrypted file or message and choose whether to copy, download, or save it — all without exposing anything to any centralized server.
