Your rent deposit, held by a contract instead of your landlord.
A security deposit is often two months of rent. Today the landlord holds it, decides the deductions alone, and returns it when it suits them. Disputing a charge means small-claims court, months later.
Four moves, three people, one contract. Follow a 1,500 tUSDC deposit from move-in to payout.
The landlord sets the amount, picks a neutral arbiter and the deadlines. The tenant sends the deposit in tUSDC or NEAR and receives an NFT that is the deposit position. From here, neither of them can move the money alone.
Landlord, then tenantEach line gets a reason, an amount and an evidence link. The photo or invoice is fingerprinted in the browser, so it cannot be swapped after the fact.
LandlordDisputing the carpet does not freeze the paint. Every line left undisputed, and the rest of the deposit, is paid out the moment the tenant answers.
TenantThe arbiter splits only the amount in dispute. Both sides withdraw their share when they like, and every step stays on the public record.
ArbiterEvery stage has a deadline set when the lease is created. When one passes, anyone can press the button that applies it.
When the tenant locks the deposit, the contract mints a NEP-171 token. Whoever holds it is the tenant: owed the refund, the only one who can answer a claim, the only tenant who can open the vault. Its image changes as the lease moves on.
The landlord approves a replacement tenant, and the NFT moves to them with the deposit, the refund rights and every tenant action. The old tenant keeps nothing.
Move-in photos and notes stay off-chain. Only the current NFT holder and the landlord can open them, checked against the chain on every request.
Get the whole deposit back and you earn a clean move-out badge. Share your rental record with the next landlord instead of a reference letter.
Lease #0 ran the full flow on the real contract: the first tenant handed the lease NFT to a replacement, who then disputed a deduction. These numbers are read from the chain as this page loads.
Hold the deposit in a dollar stablecoin so its value does not swing, or in NEAR. The demo uses tUSDC, a test token with a free faucet.
Each deduction stores the sha256 fingerprint of its photo or invoice. If the file is edited later, the fingerprint no longer matches.
Settlement credits a balance; you pull it to your wallet when you like. A failed transfer puts the balance back, so funds never get stuck.
