The Problem
02
Rental Deposits Are Built on Trust — Creating Friction & Risks for Both Parties
PAIN POINTS IN TODAY'S RENTAL MARKETS
• Tenants pay large security deposits directly to landlords without escrow protection.�• Deposit refunds are frequently delayed for weeks or months after lease completion.�• Disputes arise over property damage, cleaning costs, and repair deductions.�• Unclear lease conditions lead to subjective, unverified claims.�• Limited visibility into how deposits are held or invested during tenancy.�• Manual dispute resolution is slow, expensive, and stressful.�• Centralized platforms introduce additional intermediaries and transaction friction.�• Landlords face challenges recovering legitimate repair expenses fairly.
CORE PROBLEM
There is no neutral, transparent system that automatically enforces agreed deposit rules.
Trust-based deposits convert routine lease completions into friction, financial risk, and unnecessary legal overhead.

Product Workflow
05
How RentSafe Works (End-to-End Lifecycle)
01
Create Agreement
Landlord connects Stellar wallet and defines deposit amount, lease duration, and terms.
02
Lock Deposit
Tenant reviews terms and signs transaction. Deposit moves into Soroban escrow contract.
03
Rental Period
Escrow remains locked on-chain. Both parties monitor status with transparent history.
04
Lease Completion
Landlord submits a request for a full refund or an itemized partial deduction.
05
Tenant Review
Tenant reviews deduction request, accepts, or submits evidence for dispute review.
06
Settlement
Soroban contract automatically distributes funds: refund to tenant & approved deductions to landlord.

Smart Contract & Security Model
07
Soroban Smart Contract Architecture & Security Focus
SOROBAN ESCROW CONTRACT LOGIC
• Creates rental agreements with stored landlord, tenant, deposit amount & timeline parameters.�• Locks deposited assets securely in contract custody during the lease period.�• Restricts state mutations strictly to authorized cryptographic participants.�• Validates escrow state transitions (Created → Locked → Pending → Settled).�• Processes full refunds automatically upon clean lease expiration.�• Executes partial deductions only upon explicit tenant review & approval.�• Prevents unauthorized fund releases, early withdrawals, or locked fund deadlocks.
SECURITY & SAFETY HIGHLIGHTS
• Explicit Access Control:
Strict role-based caller verification for every contract invocation.
• State-Machine Validation:
Ensures contract actions only occur in valid lifecycle states.
• Safe Fund Custody:
Soroban contract sandbox prevents unauthorized external calls or reentrancy.
• Deterministic Settlement:
Rule execution is entirely code-enforced without arbitrary intervention.
• Minimal Off-Chain Dependency:
Escrow funds and core state do not depend on external servers.
• Security Audit Path:
Testnet-first deployment with formal security review prior to mainnet.
