ShardKeep encrypts your secrets on your device, splits them into shards across a distributed node network, and stores the shard map on the Solana blockchain — encrypted so only your wallet can read it. Not even we know where your shards are.
No master password stored anywhere. No server to hack. Just math and cryptography.
Sign in with any Solana wallet. Your signature derives a unique encryption key — only you can produce it, and it never leaves your device.
Add passwords, seed phrases, or private keys. Each secret is encrypted with AES-256-GCM on your device before anything is transmitted.
Your encrypted secret is split into fragments using Shamir’s Secret Sharing and distributed across Bastion nodes. The map of where your shards live is encrypted with your wallet key and stored on Solana — so only you can locate and reconstruct your data. Not even ShardKeep can.
Every feature is designed around one principle: you own your data.
Your encrypted shards are distributed across Bastion nodes, but the map of which nodes hold which shards is stored on the Solana blockchain — encrypted so only your wallet can read it. Breach our servers and you get nothing: we don't store shard locations. Zero-Trust architecture by design: we literally don't know where your passwords are. No other password manager can say this.
Secrets are split into n shards. Any k can reconstruct the original. Lose a few nodes — your data is still safe.
Everything is encrypted on your device with AES-256-GCM before it touches the network. We never see your plaintext.
Your wallet is your login. Sign a message, derive your key, unlock your vault. No emails, no passwords to remember.
Pawn (3-of-5), Knight (4-of-7), Bishop (5-of-9), Rook (5-of-9), Queen (7-of-12). Choose how many shards protect each secret.
