Why closings break
A residential closing involves at least seven counterparties (buyer, seller, buyer's agent, seller's agent, lender, title, escrow). A commercial closing involves more. Every counterparty runs different systems. Every step has a verbal handoff. Wire fraud against closing agents is now one of the largest single-attack-surface fraud vectors in the US — closing agents lose roughly $400M/year to compromised email instructions.
A2A Real Estate replaces verbal handoffs and email instructions with signed envelopes. Wire instructions become signed messages from the escrow agent's did:hive identity. The buyer's lender signs the funding package, bound by hash to the executed purchase agreement. Title commitment becomes a signed envelope, not a PDF emailed at midnight.
The four-corner closing, signed
1. Signed purchase agreement
Both buyer and seller agents sign the executed contract envelope. Every contingency, every deadline, every escrow term is hash-locked. Amendments become signed deltas.
2. Signed funding package
Lender agent signs the loan commitment + wire instructions, bound to the purchase agreement hash. Wire fraud surface collapses — the escrow agent verifies the signature, not the email sender.
3. Signed title + deed transfer
Title agent signs the commitment. Closing attorney signs the deed. DeedLock records the signed transfer envelope on-chain — Base 8453 anchored, ALCOA+ receipted.
Extends DeedLock. If you're already running DeedLock for title-side attestation, A2A Real Estate is the multi-counterparty wire format that connects all four corners of a closing on the same signed rail.

Frequently asked
Is this for residential or commercial closings?
Both. The envelope schema supports residential (single-family, multi-family up to small commercial), full commercial (office, industrial, retail, multifamily), and land transactions. Commercial closings benefit most because the counterparty count and document complexity are higher.
Does the county recorder accept this?
The on-chain anchor is supplementary — the deed is still filed at the county recorder in the conventional way. What changes is the audit trail before and after recording. The signed envelopes establish the chain of authority that the conventional filing reflects. Some jurisdictions are piloting acceptance of the on-chain receipt as the primary record; most still treat the county filing as primary.
How does this stop wire fraud?
The two attack surfaces are (1) compromised email instructions and (2) impersonation. A2A Real Estate eliminates both. Wire instructions arrive as signed envelopes from the escrow agent's did:hive identity, verifiable offline against a published key. Even if an attacker compromises the email channel, the signature doesn't match. The escrow agent never accepts wire instructions over unsigned email.
Do all four counterparties need to be on Hive?
Best case: yes, native end-to-end. Practical case: a closing-side bridge agent constructs signed envelopes on receipt of legacy artifacts (DocuSign PDFs, lender portal exports). This gets you a signed audit trail even when some counterparties are still on legacy rails. As more brokerages, title companies, and lenders adopt, the bridge work shrinks.
What does DeedLock add on top?
DeedLock is the title-attestation core — it's the contract that records the signed transfer envelope on Base 8453 and produces the on-chain anchor. A2A Real Estate is the multi-counterparty wire format that drives DeedLock and connects the other three corners (buyer/seller, lender, escrow). DeedLock works standalone; A2A Real Estate runs on top.
What's the price for high-volume brokerages?
The Rent tier at $999/month covers unlimited closings — that's the right tier for brokerages doing 50-500 closings/month. Above that, the Lease tier at $9,999/year covers multi-state operations with multiple title underwriters and dedicated integration support.
