Shield
Tamper-proof evidence for every deal before it's signed
Most contract disputes don't start at the contract. They start before it, in the negotiation, the promises, the documents exchanged. Shield captures everything before a contract is signed and seals it with SHA-256 hashing and RFC 3161 timestamping. Every message, document view, negotiation step, and approval becomes tamper-proof and court-admissible. When someone says "that's not what we agreed," you have proof. Built for B2B SaaS, FinTech, and Real Estate platforms via REST API and SDK.
"The deal was fine. The problem started before we got to the contract."
Verbal terms. Changed documents. Promises nobody could prove.
That gap became Shield. Every interaction before a contract is signed gets sealed with SHA-256 hashing and RFC 3161 timestamping. Tamper-proof. Legally verifiable.
Looking for 3 pilot users I'll upgrade you to Business and work with you directly to make sure it fits your workflow.
Happy to answer any questions about the technical implementation or use cases.
