In the current global digital economy, B2B service transactions (freelance, consulting, software development) are plagued by a fundamental lack of security:
- Payment Risks: Clients are often forced to pay 50-100% upfront to "lock in" a provider, with no guarantee of quality.
- Delivery Risks: Providers often complete work only to face "scope creep" or clients who vanish without paying the final invoice.
- Complex Disputes: When things go wrong, there is no centralized, evidence-based system to resolve issues fairly.
- Opaque Reliability: General review systems are easily manipulated; there is no data-driven "Trust Score" linked to actual financial outcomes.
TrustLayer redefines how businesses interact by acting as a neutral, automated intermediary. Our platform ensures that trust is built into the protocol, not just the contract.
- Smart Escrow: When a contract starts, the client's funds are moved into a secure "Held" state.
- Verified Delivery: The provider submits their work through the platform.
- Outcome Verification: The client reviews the output. Only upon explicit verification are the funds released.
- Automated Arbitration: If a dispute arises, the funds remain locked until a resolution is reached based on submitted evidence.
- Multi-Factor Authentication: Secure login using JWT and Google OAuth 2.0.
- Role-Based Access Control (RBAC): Distinct interfaces and permissions for 'Clients', 'Freelancers', and 'Admins'.
- Escrow-as-a-Service: Automated holding and releasing of funds based on milestone verification.
- Transaction History: Immutable record of all financial movements for auditing and tax purposes.
- Evidence Vault: Securely upload screenshots, contracts, and documents as proof during a dispute.
- Resolution Tracking: Transparency into the status of active disputes and historical outcomes.
- Trust Scores: A mathematical reliability score calculated from successful project completion rates and dispute history.
- Service Marketplace: A curated directory where providers can list specialized services and clients can initiate secure contracts instantly.
- Sleek UI/UX: A modern, dark-themed interface built for professionals.
- Real-time Notifications: Stay updated on escrow status, new messages, and dispute updates.
