Contracts, records and documents that must not vanish
Signed contracts, tax records, compliance documents. When a paper trail must survive for decades, put it somewhere designed to last.
Archive a DocumentImmutable records
Each document gets a transaction ID on a public ledger. Prove what existed, when, and that it was not altered.
Small files, zero cost
Most documents are under 100 KB — stored free forever. Archive hundreds of contracts without spending a cent.
Confidentiality option
Encrypt sensitive documents in your browser so only authorized people can read them.
01The document problem
A company's important records usually live in email attachments, local drives and subscription cloud folders — spread out, and at risk whenever an account closes or a drive dies.
Long Drive gives documents a single, permanent home. Upload the final signed version; the transaction ID and hash let you prove its integrity years later.
02What to archive first
Start with legal documents: signed contracts, non-disclosure agreements, incorporation papers. Then add tax records, invoices and audit evidence.
For contracts that must be provable but not public, enable encryption. You keep the password; nobody else can read the archive.
03The practical case
A small consulting firm archived 400+ signed client contracts — PDFs averaging 60 KB. Total storage cost: zero (free tier). They now have a permanent, tamper-evident record for every engagement.
Auditors can verify each file's transaction ID on the public Arweave ledger without relying on the firm's servers.
Document archive FAQ
Is a stored contract legally meaningful?
Long Drive preserves the file and proves its integrity via transaction ID and hash. Whether that satisfies a particular legal requirement depends on your jurisdiction — consult a professional for compliance matters.
What if I need to update a document?
Arweave files are immutable. Upload a new version as a separate transaction — the old one remains as evidence of what existed before.
Can I grant others access to view?
Yes — each file has a permanent link you can share. For encrypted documents, recipients need the password to decrypt.
