The platform
Everything you need to capture, anchor, and verify proof
One network, from the phone in someone's hand to the record on-chain.
Free Capture App
Anyone can capture a photo or document. Each capture is signed on device and queued in an offline-first ledger — at no cost, forever.
Learn moreAnchored on Solana
Proofs are written to a Solana program, so verification does not depend on Kist being online, honest, or even in existence.
Learn moreCLI & SDK
Install the CLI, log in, and anchor or verify from any terminal. Or wire the JavaScript SDK into your own backend and CI.
Learn moreHTTP API
A clean JSON API with signed anchors, batch sync, and verification that reads the chain directly. Keys are metered, postpaid.
Learn morePay as you go
Pay-as-you-go beta access is manually approved after UPI payment review. Credits are consumed as you anchor and verify.
Learn moreVerify anything
Upload an image and Kist hashes it, looks it up on-chain, and returns the original record — timestamp, device, and owner.
Learn more Capture App
Sign on device. Anchor on-chain.
The free Flutter app generates a device key on first launch, signs every capture locally, and queues it in an offline-first ledger. Sync happens whenever there is a network — the proof is already valid.
- Ed25519 signature generated on the device — the key never leaves it
- Works fully offline; batch syncs later without losing timestamps
- Free for Android and iOS, with no account required to capture
For developers
Install, log in, verify.
The CLI and JavaScript SDK speak the same API. Anchor signed captures from your backend, sync a fleet of devices, or verify a hash in a single call.
