HiveLex turns every contract event into a court-grade receipt. Signed twice, anchored once, valid in 2055.

This is a $5B+ contract lifecycle management market. DocuSign, Ironclad, Harvey, and Spellbook give you signatures and clauses. None of them give you a post-quantum durability layer that survives the moment classical Ed25519 gets broken. LEX-Contract sits underneath them. Every clause negotiation, every redline, every signature, every effective-date clock start, every breach notice, and every termination gets captured as a dual-signed (Ed25519 + ML-DSA-65) receipt anchored to Base 8453. Ed25519 alone falls to a quantum computer. NIST FIPS 204 (ML-DSA) does not. Per event, it's $0.0096 per contract lifecycle receipt.

The ROI on a single matter, fifteen years out

LEX-Contract ingests events from any e-signature platform, CLM, or AI contract drafter already in place. Every lifecycle transition becomes a dual-signed receipt with a chain pointer to its predecessor. The numbers a general counsel or head of legal operations presents to the audit committee are these.

An AmLaw 100 firm running roughly 50,000 matter-bearing contract events a year spends on the order of $480 / year at $0.0096 per event. Compare that to a single $40M acquisition where a reps-and-warranties claim turns on a 2031 quantum-break authentication challenge. The math makes the case on its own.

Receipt rail, not a CLM

CLM vendors own the negotiation room, the clause library, and the e-signature wrapper. AI contract drafters generate the redlines. LEX-Contract does neither. It produces the signed, anchored receipt that proves a clause was negotiated, a signature was applied, an effective date started, a breach notice was served, and a termination happened, in that order, by those parties, at those times. Keeping that separate is the whole point.

Every law firm, in-house legal team, M&A diligence room, and litigation discovery vendor produces the same kind of evidence under different vendor names. The evidence doesn't depend on any one platform, which is what makes it hold up to a federal assess under FRE 902(13)/(14) self-authentication, to a regulator under ISO/IEC 27037 digital-evidence handling, or to opposing counsel who has no reason to give you the benefit of the doubt.

How a $40M acquisition’s reps-and-warranties survives 2031 quantum-break

A specific, narrated example. A buyer closes a $40M asset acquisition in 2026 with a five-year reps-and-warranties survival period. In 2031 a cryptanalytically-relevant quantum computer breaks Ed25519. The seller’s CFO disputes a working-capital adjustment claim and challenges the authenticity of the executed SPA. The clock is the only thing that matters now.

Live verification: what a verifier sees

The envelope is CBOR-canonical and checks out offline against the issuer’s published public keys. No Hive call is needed at verification time. The panel below is the same shape every CLM, e-signature gateway, court-admissible inspection tool, or M&A diligence vendor renders.

That panel is the whole product surface a court or a diligence team needs. No demo. No login. The evidence is its own proof, and the proof still works in fifty years on a laptop with no internet.

Standards: what LEX-Contract adds

Every existing contract and digital-evidence standard answers a different question. LEX-Contract doesn't replace any of them. It adds the cryptographic binding that makes each one hold up after the fact, including against a quantum computer.

The contract envelope

Every lex_contract_*_attest call returns an envelope containing contract id, lifecycle state, matter id, party DIDs (buyer, seller, escrow, counsel, witness), executed clause hash array, e-signature envelope id (DocuSign / Adobe Sign / Dropbox Sign / Ironclad), executed-at timestamp, effective-at timestamp, survival-through timestamp, prior-attestation id, anchor txid on Base 8453, and dual signatures (Ed25519 + ML-DSA-65). The signatures bind every field. Any tamper attempt invalidates verification.

The envelope is CBOR-canonical. Verification works offline against the issuer’s published public keys. ML-DSA-65 (NIST FIPS 204) is the post-quantum signature; Ed25519 (RFC 8032) provides classical assurance. Both must verify for the receipt to be valid. Receipts remain valid through key rotation via signed key history, so a 2026 SPA still authenticates cleanly in a 2046 deposition.

What this is not

Calibrated expectations are part of the product. LEX-Contract is narrow on purpose.

Pricing

Per-event pricing means every contract lifecycle receipt is billed at $0.0096 with no baseline commitment. Volume commits from $5,000 / month bundle events at the same $0.0096 rate; overage is billed at the SET rate. Settlement: USDC on Base 8453 via x402. Treasury 0x15184Bf50B3d3F52b60434f8942b7D52F2eB436E exists and is on-chain. Receipts settle in seconds; invoicing is monthly net-30 by default.

Field map

LEX-Contract binds every contract lifecycle transition to a dual-signed receipt that drops cleanly into existing CMI 1.0, Ironclad API, DocuSign API, and LEDES pipelines. Each call accepts the correlation fields below; the envelope round-trips through standard JSON / CBOR transports via the Hive Receipt primitive.

Cross with HiveComply when SOC 2, ISO/IEC 27037, or GDPR audits touch the matter. HiveComply reads LEX-Contract receipts natively. Cross with Atticus when a contract dispute escalates to litigation, and with DeedLock when the contract is a real estate closing.

Hive runs the receipt rail underneath the broader A2A · agent-to-agent commerce category.
