Why Nautilius
Protect negotiating leverage.
A conventional auction reveals bidders, offer sizes and timing. Nautilius puts sensitive fields onchain only as ECIES ciphertext.
Verify the decision.
The clearing result is bound to the auction, command, chain and expected TEE signer, then checked onchain before it can change deal state.
Settle with safe exits.
Exact-transfer FTestXRP escrow supports funding deadlines, consent evidence, completion, cancellation and buyer refunds.
Privacy boundary
Confidential by design.
Precise about the limits.
Nautilius does not call a hash “privacy” or an HTTPS response “attestation.” The interface separates encrypted negotiation, public evidence, and remaining trust assumptions.
Inside the encrypted instruction
- Buyer wallet identity
- Offer amount
- Replay-protection nonce
- Signed offer expiry
On Coston2 and in receipts
- Parcel and evidence commitments
- Opaque instruction ciphertext
- Selected buyer and clearing amount
- Escrow and lifecycle state
The remaining trust boundary
- TEE registry membership and key
- Fresh Confidential Space attestation
- Approved code hash and platform
- Signed FCC ActionResult
Live Coston2 proof
Receipts, not promises.
Nautilius’s contracts and public FCC extension are deployed and independently readable today. The confidential production path stays disabled until a real active machine is registered.
Current boundaryNo active production TEE
Extension 66252 has no approved production code hash or active machine. No live FCC action, attestation or FTestXRP settlement is claimed.

How it works
One disciplined path from parcel to proceeds.
Each stage produces evidence the next stage must verify. Missing infrastructure or authorization stops the flow visibly.
- 01
Commit
Seller hashes title evidence locally and registers parcel-bound commitments.
- 02
Offer
Buyer signs an expiring offer and encrypts every sensitive field.
- 03
Clear
The TEE clears deterministically without returning losing bids.
- 04
Settle
Verified result gates escrow, evidence milestones and safe exits.
Nigerian legal boundary
Coordination infrastructure—not a land authority.
Nautilius coordinates confidential bidding, escrow and tamper-evident evidence records. It does not issue a Certificate of Occupancy, determine legal ownership, perform professional due diligence, obtain Lagos State Governor’s Consent, or replace official land registration.
Enter the deal workspace.
Inspect the live deployment, prepare real parcel evidence, and follow every prerequisite without simulated success.
