RentLock holds your security deposit in a smart contract vault that neither you nor your landlord can touch without both agreeing — or an arbitrator ruling. On-chain proof of every payment. Zero trust required.
Cash, Venmo, and bank transfers were not designed for rental agreements. They leave you with no proof, no protection, and no recourse when things go wrong.
From signing the lease to getting your deposit back — every step is on Solana. Every payment is yours forever.
Your landlord sets the terms — rent amount, security deposit, due date, lease duration — and deploys them to Solana. You receive the lease details linked to your wallet address. The terms are immutable. Neither party can change them after deployment. No verbal agreements, no fine print, no surprises.
Your security deposit goes into a Program Derived Address (PDA) vault on Solana — not into your landlord's bank account. The vault has no private key. It's controlled entirely by the smart contract logic. Your landlord cannot access your deposit unless the contract authorizes it. If the lease ends cleanly, the code returns it to you automatically.
On your due date, you send rent to the escrow vault with a single wallet signature. The transaction is confirmed on Solana in under 400ms. It's permanently recorded with a timestamp, your wallet signature, and the amount. Your landlord cannot claim the payment never arrived — it's on the blockchain. Immutable. Public. Yours.
Every rent payment generates an on-chain record: the transaction signature, block number, timestamp, and amount. Anyone can verify it — your landlord, a court, a future landlord doing a reference check, or your accountant. You can export your full payment history at any time directly from Solana Explorer. No screenshots. No PDFs. Cryptographic proof.
If your landlord violates the lease — refuses to return your deposit after a clean tenancy, claims you missed a payment the blockchain clearly recorded, or tries to change terms — you file a dispute in seconds from the app. The escrow is frozen immediately. A neutral, staked arbitrator reviews the on-chain evidence and rules. You don't need a lawyer. You don't need to go to court. The blockchain has your receipts.
When the lease ends cleanly, your landlord initiates the lease closure with one transaction. If everything checks out, the smart contract returns your deposit to your wallet automatically — no waiting 30 days for a check, no landlord claiming mysterious damages at the last minute without proof. If there's a dispute, the arbitrator decides. Either way, the outcome is enforced by code, not trust.
Your deposit is in a smart contract vault — not in your landlord's savings account where they can spend it, forget it, or lose it. The code holds it. The code returns it. No landlord discretion required.
Every payment is timestamped, signed by your wallet, and stored on Solana permanently. You have cryptographic proof you paid on time, every time — forever. No screenshots, no paper receipts that can be lost or disputed.
Build an on-chain payment history that travels with you. Future landlords can verify your track record directly from Solana — no need for bank statements, reference letters, or calls to your previous landlord. Your record speaks for itself.
If anything goes wrong, you can freeze the escrow and trigger on-chain arbitration in seconds. The blockchain record is your evidence — payment timestamps, signed lease terms, transaction history. A neutral arbitrator rules. The outcome is enforced by code.
“I never received that payment.” Not possible on RentLock. The blockchain records everything. Paid on the 1st at 9:42am? It's there. Paid for 11 straight months? It's there. The ledger doesn't lie, doesn't forget, and can't be altered.
At the end of a clean lease, your deposit is returned to your wallet by the smart contract automatically. No waiting 30 days. No landlord “finding” new damages right before move-out. The code executes the return — no human decision required.
