Handshake deals,
upgraded with proof.
Legal-grade evidence for everyday agreements — without lawyers, paperwork, or subscriptions you don't need.
A verbal deal or a scanned PDF
No written proof
The terms live in memory — or an email thread nobody can find six months later.
Risk of fraud
Forged signatures, identity swaps, and back-dated documents are almost impossible to detect.
Disputes with no evidence
If things go sideways, there's nothing you can hand a court or a platform to settle it.
An agreement a judge can verify
Digital signature
Every signature is cryptographically bound to the exact document bytes both parties reviewed.
Timestamped proof
Each step — send, accept, sign — is recorded with a tamper-evident timestamp and hash.
Optional identity verification
Face-matched KYC for high-value deals, so you know who actually signed.
Stored for 5 years
Secure EU custody for half a decade, with an optional permanent blockchain anchor.
Most disputes don't start with bad faith — they start with no record.
Democratizing evidentiary safeguards.
Courts, banks, and big platforms have always had access to proof. Everyone else has been left with a handshake. SACO brings the same evidentiary rigor — hashes, timestamps, identity — to the transactions ordinary people actually make.
