About UntilReady

UntilReady is a cryptographic evidence preservation platform. We help individuals, legal professionals, and organizations create tamper-proof records of digital files — with mathematical proof they haven't been altered since the moment they were sealed.

Traditional notarization is slow, expensive, and fundamentally based on trust: you trust the notary, the institution, the paper trail. We replace that trust with math. Every file uploaded to UntilReady is encrypted in your browser before it ever leaves your device. A cryptographic hash — your file's unique fingerprint — is computed and anchored permanently to the Arweave blockchain. No one can alter it. No one can delete it. Not even us.

UntilReady is built on open standards. Arweave for permanent, decentralized storage. Merkle trees for efficient proof aggregation. Client-side encryption so your data stays yours. Every proof we generate is independently verifiable by anyone, anywhere — no account required.
