🌟 StellarTrustEscrow

A decentralized, milestone-based escrow platform with an on-chain reputation system — built on the Stellar blockchain using Soroban smart contracts.

---

📖 Overview

StellarTrustEscrow allows clients and freelancers to create trustless payment agreements secured by Soroban smart contracts. Funds are locked on-chain and released milestone by milestone — no intermediaries, no trust required.

Every completed milestone builds an immutable, on-chain reputation score for freelancers and clients, creating a trustworthy track record that persists across all future engagements.
