HOW IT WORKS

Cryptographic proof at every handoff.

DNAChain wraps your existing sample workflow in an immutable, regulator-ready audit trail — without changing how your team works day to day.

STEP 1

Submit

A custody event is captured with actor, location, and timestamp through the UI, API, or LIMS integration.

STEP 2

Hash

A SHA-256 digest is computed deterministically from the canonical record — including the previous event hash, forming an unbroken chain.

STEP 3

Anchor

The hash is committed to a Polygon smart contract. Average confirmation time is 2.1 seconds. We absorb the gas fees.

STEP 4

Verify

At any time — or on every export — we re-hash the live record and compare against the on-chain commitment to prove integrity.
