Please read these terms carefully before using RentLock. Last updated: March 2026.
Subject to revision before final publication. This document does not constitute legal advice. Consult a licensed attorney in your jurisdiction for legal guidance specific to your situation.
By accessing or using the RentLock platform — including the web application, smart contracts, API, and any related services — you agree to be bound by these Terms and Conditions. If you do not agree to these terms in full, do not use the platform. Continued use of RentLock after any modification to these terms constitutes acceptance of the revised terms.
RentLock is a decentralized rent escrow platform built on the Solana blockchain, developed and maintained by LBF Labs LLC. RentLock facilitates the creation of on-chain lease agreements, automated escrow vaults, rent payment tracking, and dispute resolution between landlords and tenants. RentLock is not a bank, financial institution, law firm, property management company, or licensed real estate broker. We do not provide legal, financial, tax, or investment advice.
Nothing on this platform constitutes legal counsel or creates an attorney-client relationship.
RentLock is entirely non-custodial. LBF Labs LLC never holds, controls, or has access to user funds at any time. All funds are held in Program Derived Address (PDA) vaults controlled solely by the on-chain smart contract logic. PDA vault accounts have no private key and cannot be accessed by any individual — including RentLock employees, developers, or LBF Labs LLC. Fund release is governed exclusively by the program logic.
The canonical RentLock program is deployed at: Program ID: D2ynTEzqRnvHPV4Ngij4y5S9RJSK2drapqR7NTvPZcVx Users should verify this address before interacting with the platform.
Blockchain technology and smart contracts are experimental. By using RentLock, you acknowledge and accept the following risks:
You are solely responsible for the security of your Solana wallet and private keys. RentLock never requests your seed phrase, private key, or wallet password under any circumstances. Lost wallet access means permanently lost funds — there is no account recovery, password reset, or support escalation path that can restore access to a non-custodial vault. You are responsible for maintaining secure backups of your wallet credentials.
The on-chain lease record created by RentLock is a cryptographic supplement to a rental agreement — it is not a substitute for a legally executed written lease under applicable landlord-tenant law. RentLock strongly recommends that all parties execute a written lease agreement that complies with local law in addition to creating an on-chain record.
The on-chain record provides verifiable proof of payment and deposit terms, but does not replace the legal instrument required in most jurisdictions to establish a landlord-tenant relationship.
The arbitrator for a lease is set at lease creation time by mutual agreement of the parties and is recorded immutably on-chain. Arbitrator decisions are executed directly on-chain and are final with respect to the escrowed funds. RentLock's dispute mechanism does not constitute binding legal arbitration under the Federal Arbitration Act or any equivalent statute. Users retain all rights to pursue legal remedies in courts of competent jurisdiction.
On-chain arbitration affects only the disposition of escrowed funds — not broader legal claims, damages, or remedies that may exist under applicable law.
RentLock charges a platform fee of 0.5% on each rent payment processed through the protocol. This fee is non-refundable under all circumstances, including failed transactions, disputed leases, and early termination. Fee configuration is stored on-chain in the PlatformConfig account and may be updated by the program authority. Updated fee rates apply to new transactions only; existing lease terms are not retroactively affected.
All fees are deducted automatically at the time of payment execution and are recorded on-chain.
To prevent permanent fund lockup, RentLock implements a permissionless release mechanism. After a defined inactivity window expires — during which neither party has acted to resolve a dispute or complete a lease — any party (or any third party) may trigger a release transaction. This mechanism is a safety feature, not an endorsement of any particular outcome.
Users acknowledge that permissionless release is an intentional protocol design choice and agree that LBF Labs LLC bears no liability for fund outcomes resulting from its execution.
RentLock operates on the Solana blockchain and is dependent on third-party infrastructure including Solana validator nodes, RPC providers including Helius, wallet software, and web browsers.
LBF Labs LLC is not responsible for:
We recommend using the platform during periods of normal network activity for time-sensitive transactions.
You are solely responsible for ensuring that your use of RentLock complies with all applicable laws, regulations, and ordinances in your jurisdiction. This includes but is not limited to landlord-tenant law, consumer protection law, securities regulations, anti-money laundering requirements, and tax obligations. RentLock does not represent that the platform is lawful or appropriate in all jurisdictions. If use of this platform is prohibited or restricted in your location, you must not use it.
You must be at least 18 years of age to use RentLock. By using the platform, you represent and warrant that you are 18 or older and have the legal capacity to enter into a binding agreement. Use by minors is strictly prohibited.
The RentLock name, logo, brand, and user interface are the property of LBF Labs LLC. Patent pending. Trademarks pending. The RentLock smart contract program is open source and available for review. Open source availability does not grant rights to deploy competing products using the RentLock name, brand assets, or proprietary UI elements. You may not reproduce, distribute, modify, or create derivative works of RentLock's brand assets or proprietary UI without prior written consent from LBF Labs LLC.
RentLock does not collect personally identifiable information (PII). There is no KYC process, no account registration, and no personal data stored on our servers. All on-chain data — including wallet addresses, payment amounts, lease terms, and dispute records — is publicly visible on the Solana blockchain by design. This is inherent to blockchain technology.
Any nicknames or display labels you set within the RentLock interface are stored locally in your browser only and are never transmitted to RentLock servers or recorded on-chain.
To the maximum extent permitted by applicable law, LBF Labs LLC's total aggregate liability to you for any claims arising from or related to your use of RentLock — regardless of the form of action — shall not exceed the total platform fees you paid in the twelve (12) months preceding the claim.
In no event shall LBF Labs LLC be liable for indirect, incidental, special, consequential, or punitive damages, including loss of profits, loss of data, loss of funds, or business interruption, even if advised of the possibility of such damages.
RentLock is provided “as is” and “as available” without warranty of any kind, express or implied. LBF Labs LLC expressly disclaims all warranties including, but not limited to, implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement. We do not warrant that the platform will be uninterrupted, error-free, secure, or free of viruses or other harmful components.
We do not warrant that any transactions will be processed successfully or within any particular timeframe.
You agree to defend, indemnify, and hold harmless LBF Labs LLC, its officers, directors, employees, contractors, agents, licensors, and successors from and against any and all claims, damages, losses, liabilities, costs, and expenses including reasonable attorneys' fees arising out of or related to:
The RentLock smart contract is deployed on the Solana blockchain and operates independently of LBF Labs LLC's continued existence. In the event that LBF Labs LLC ceases operations, dissolves, or discontinues the web application, the on-chain program will continue to function as long as the Solana network operates.
Users acknowledge that the program authority may be transferred, revoked, or frozen as part of any wind-down process, and that existing vaults will continue to be governed by the program logic already deployed on-chain at the time of any such event.
LBF Labs LLC reserves the right to modify these Terms and Conditions at any time. Changes will be posted at this URL with an updated effective date. We may, but are not obligated to, notify users of material changes via the platform interface. Your continued use of RentLock after the posting of any modified Terms constitutes acceptance of those changes. If you do not agree to the revised terms, you must discontinue use of the platform.
These Terms and Conditions shall be governed by and construed in accordance with the laws of the State of Wyoming, without regard to its conflict of law provisions. Any legal action or proceeding arising out of or related to these terms or your use of RentLock shall be brought exclusively in the state or federal courts located in Wyoming, and you consent to personal jurisdiction in those courts.
