What is RentLock

Eliminating trust from the
rental equation.

Every month, millions of tenants send rent to landlords with nothing but a handshake and a paper receipt. Security deposits sit in personal bank accounts with no accountability. Disputes drag on for months with no neutral arbiter. RentLock replaces the entire trust layer with math — rent is locked in a smart-contract vault on Solana, and neither party can touch it until the agreed conditions are met.

How It Works

Simple. Secure. On-chain.

Three steps from lease to payout — no middlemen, no paperwork, no chasing.

01

Landlord creates lease

Set rent amount, due date, and tenant wallet. The smart contract deploys to Solana — immutable and tamper-proof.

02

Tenant pays into escrow

Rent goes into a neutral smart-contract vault. The tenant gets instant on-chain proof of payment — forever.

03

Release on due date

The landlord releases funds to their wallet with one click. The smart contract enforces the terms automatically.

Why the Vault is Safe

Locked by math, not people.

Program Derived Address

The vault is a PDA — a Solana account whose address is mathematically derived from the program and lease participants. Nobody holds a private key. No one can move funds without the correct on-chain instruction.

Permission Gating

Every instruction verifies identities on-chain. Only the landlord can release rent. Only the tenant can pay. Only the arbitrator can resolve disputes — enforced at the protocol level.

Open Source & Auditable

The RentLock smart contract is fully open source. Every line of code is publicly verifiable on Solana. You don't have to trust our team — you can read the math yourself.
