Why closings break
A typical home closing has at least seven parties involved: buyer, seller, buyer's agent, seller's agent, lender, title company, and escrow. A commercial closing has even more. Every party runs its own systems. Every step involves someone picking up the phone. Wire fraud aimed at closing agents is now one of the biggest fraud problems in the country. Closing agents lose roughly $400 million a year to fake email wire 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
The lender's agent signs the loan commitment and the wire instructions, tied to the purchase agreement's hash. This shuts down the wire fraud problem, because the escrow agent checks the signature, not who sent the email.
3. Signed title + deed transfer
The title agent signs the commitment. The closing attorney signs the deed. DeedLock records the signed transfer on-chain, anchored on Base 8453 with an ALCOA+ receipt.
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 message format handles homes (single-family up through small commercial), full commercial deals (office, industrial, retail, multifamily), and land deals. Commercial closings gain the most because they have more parties and more complicated paperwork.
Does the county recorder accept this?
The on-chain anchor adds to the process, it doesn't replace it. The deed still gets filed at the county recorder the normal way. What changes is the paper trail before and after that filing. The signed messages create a chain of authority that the county filing then reflects. A few places are testing whether they'll accept the on-chain receipt as the main record, but most still treat the county filing as the one that counts.
How does this stop wire fraud?
There are two ways fraud gets in: someone fakes an email, or someone impersonates a party in the deal. A2A Real Estate closes off both. Wire instructions show up as signed messages from the escrow agent's did:hive identity, and you can check that offline against a published key. Even if someone hacks the email account, the signature won't match. The escrow agent never accepts wire instructions sent over plain, unsigned email.
Do all four counterparties need to be on Hive?
In the best case, yes, everyone is on Hive end to end. In practice, a bridge agent on the closing side can build signed messages from older documents, like DocuSign PDFs or lender portal exports. That still gets you a signed audit trail even when some parties are still using older systems. As more brokerages, title companies, and lenders come on board, less bridging is needed.
What does DeedLock add on top?
DeedLock is the core piece that proves title. It's the contract that records the signed transfer on Base 8453 and creates the on-chain anchor. A2A Real Estate is the format that lets many parties send signed messages, and it connects the other three corners of the deal: buyer and seller, lender, and escrow. DeedLock works on its own. A2A Real Estate builds on top of it.
What's the price for high-volume brokerages?
The Rent tier at $999 a month covers unlimited closings, which is the right fit for brokerages doing 50 to 500 closings a month. Above that, the Lease tier at $9,999 a year covers operations running in multiple states with several title underwriters, plus dedicated help getting set up.
