You secured your property address on the blockchain. Now, a few years later, you are ready to sell. What happens to your Tier 1 NFT? Does it complicate the sale? Do you need to do anything before closing? Here is exactly what happens — and what it means for the buyer.
You made a smart decision. A few years ago, you secured your property address on the blockchain through PropyKeys Tier 1 — establishing a timestamped, permanent onchain record that your address existed in your wallet as of that date. Now you are ready to sell. And you have one very reasonable question: what happens to that blockchain record?
The short answer is this: your Tier 1 address NFT does not block, complicate, or delay your home sale in any way. The traditional real estate closing process proceeds exactly as it always has — the county records the new deed, funds are disbursed, keys are exchanged. The blockchain record is a separate, parallel layer that operates independently of the legal transfer of ownership.
What Tier 1 Is — and Is Not
It is worth being precise about what a Tier 1 PropyKeys mint actually represents before discussing what happens at sale. A Tier 1 mint registers your property address on the Base blockchain. It creates a timestamped, immutable record that this address was associated with your wallet on a specific date. It is a digital marker — an early stake in the blockchain property recording infrastructure that is being built right now.
A Tier 1 mint is not a legal deed. It does not replace or interact with the county recording system. Legal ownership of a property in the United States is still determined by what is on file at the county recorder's office. Your Tier 1 NFT is a parallel onchain record, not a substitute for the traditional chain of title.
This distinction matters at sale. Because the Tier 1 NFT is not part of the legal title chain, it does not need to be transferred, burned, or otherwise dealt with as a condition of closing. Your title company does not need to know about it. Your buyer's lender does not need to know about it. The closing proceeds on the traditional track.
What Actually Happens at Sale
Step 1: List and Close Normally
Work with your real estate agent to list and market your property exactly as you would in any traditional sale. Your Tier 1 blockchain record does not appear on the MLS, does not affect your listing price, and does not change any aspect of the marketing or closing process. The county records the new deed in the buyer's name. That is the legal transfer of ownership. Your Tier 1 NFT is unaffected by this.
Step 2: Decide What to Do With Your NFT
After closing, you have two options for your Tier 1 NFT. You can keep it in your wallet as a historical record — it simply sits there as a timestamped artifact of your ownership of that address. It has no ongoing legal significance once you no longer own the property, but it is a permanent record of the fact that you were the first person to establish an onchain presence for that address. Alternatively, you can transfer it to the new owner via any Base-compatible NFT marketplace such as OpenSea. This is a courtesy gesture — it gives the new owner the address registration in their own wallet, which may be meaningful to them if they choose to build on that onchain foundation in the future.
Neither option is legally required. There is no obligation to transfer or burn the Tier 1 NFT at sale. It is simply a question of what you and the buyer prefer.
Step 3: The New Owner Starts Their Own Journey
Whether you transfer the Tier 1 NFT or keep it, the new buyer inherits a home with a verifiable onchain history. If they want to establish their own Tier 1 record — or pursue higher tiers as the PropyKeys infrastructure matures — they can do so independently. The onchain record you created does not expire, does not transfer any rights, and does not create any obligations for the new owner.
Does the Blockchain Record Affect My Property Taxes or Title Insurance?
No, on both counts. Property taxes are assessed by your county based on the official recorded deed — the blockchain record has no bearing on this calculation. Title insurance is issued based on the traditional title search conducted by a licensed title company. The Tier 1 blockchain record is a separate layer that does not interact with any existing legal or financial instrument.
What About the PropyKeys Tier System at Sale?
PropyKeys operates on a three-tier system, and what happens at sale depends entirely on which tier you hold. Mint My Property currently offers Tier 1 minting — the foundational address registration. Tier 2 (Deed Onchain) and Tier 3 (Asset Onchain / RWA) involve deeper integration with the legal ownership record and are handled differently. If you hold a higher tier, the process at sale is more involved and should be coordinated with Propy directly.
| Tier | What It Is | What Happens at Sale |
|---|---|---|
| Tier 1 — Address Onchain | Property address registered on Base blockchain | Traditional sale proceeds normally. NFT stays in seller's wallet or can be transferred to buyer. No action required. |
| Tier 2 — Deed Onchain | Deed encrypted on IPFS, minted as onchain title record | Traditional sale proceeds normally. NFT is burned by Propy after closing. Coordinate with Propy. |
| Tier 3 — Asset Onchain (RWA) | Property fully tokenized as a Real World Asset NFT | The NFT IS the legal ownership vehicle. Transferring the NFT transfers the property. Coordinate with Propy. |
The Bigger Picture
The most important thing to understand about your Tier 1 mint is what it represents in the long arc of property recording history. Most US counties are still operating on paper-based recording systems. The transition to digital — and eventually blockchain-based — land registries is underway, but it will take years to reach full adoption. Your Tier 1 mint is an early position in that future infrastructure.
When you sell your home, that early position does not disappear. The onchain record of your ownership exists permanently on the Base blockchain. The new owner inherits a property with a documented onchain history — a foundation they can build on as the PropyKeys ecosystem grows. That is the value of being early.
Summary
- Your Tier 1 NFT does NOT block, complicate, or delay a traditional home sale.
- The traditional closing process — county recording, title insurance, escrow — proceeds exactly as normal.
- After closing, you can keep the NFT as a historical record or transfer it to the new owner.
- Neither option is legally required.
- Property taxes and title insurance are completely unaffected by the blockchain record.
- The new buyer inherits a property with a documented onchain history.
- If you hold Tier 2 or Tier 3, coordinate with Propy directly — the process is different.
