Why SecureDrop?

The only file transfer platform with complete Zero-Knowledge anonymization

Cryptographic Privacy

Complete anonymization via ZK proofs. Sender and recipient invisible on blockchain. Privacy guaranteed by Zero-Knowledge cryptography.

Multi-Layer Security

Automatic CSAM detection (HashLookup, PDQ, TMK), abuse protection, IP/wallet blacklisting, and E2E encryption.

100% Decentralized

Decentralized IPFS storage, Base L2 blockchain, no centralized server. Censorship-resistant, fault-tolerant, and attack-resistant.

Features

E2E Encryption

End-to-end encryption with libsodium. Your files are secured before they're even uploaded.

Blockchain Proof

Cryptographic proof on Base L2. Immutable verification while preserving complete anonymity via ZK proofs.

Auto-Destruct

Your files automatically delete if they're not downloaded within the deadline.

IPFS Storage

Files stored on IPFS, a decentralized network. No centralized servers.

PDF Certificate

Download a proof certificate with cryptographic signature for each transfer.

CSAM Protection

Multi-layer automatic detection (HashLookup, PDQ, TMK) to block illegal content. Maximum security.

Complete ZK Anonymization

Sender and recipient 100% anonymous via ZK proofs on Base. Anonymous downloads guaranteed by Zero-Knowledge cryptography.
