The Problem It Solves Freelance transactions today rely heavily on centralized platforms to manage payments, file exchanges, and dispute resolution. This creates significant trust and security challenges for both clients and freelancers. Freelancers often face the risk of non-payment after delivering work. Clients hesitate to release funds upfront without assurance of quality delivery. Additionally, centralized platforms charge high commission fees and store sensitive files on centralized servers, increasing the risk of data breaches and unauthorized file usage. There is currently no seamless, decentralized solution that ensures: 🔒 Secure and trustless payment handling 📦 Protection of digital intellectual property before payment ⚖️ Transparent and automated workflow management 🚫 Reduced dependency on intermediaries 💡 How FairDeal Makes It Easier and Safer FairDeal is a decentralized freelance marketplace built on the Stellar blockchain using Soroban smart contracts. It replaces trust in intermediaries with trust in code. 🛡️ 1. Trustless Escrow Payments Funds are locked inside a smart contract at the time of job creation. The platform does not control the funds. Payment is automatically released to the freelancer only when the client approves the work, or refunded if the deal is cancelled. This eliminates payment fraud and ensures fairness for both parties. 🔐 2. Encrypted & Secure File Delivery Files are encrypted before being uploaded to IPFS Clients can only view watermarked previews before approval Original files are accessible only after payment confirmation This prevents unauthorized downloads and protects intellectual property. 🌐 3. Decentralized Storage Work files are stored on IPFS rather than centralized servers, reducing the risk of censorship, data breaches, and single-point failures. ⚡ 4. Reduced Friction Wallet confirmations are required only for fund movements Submissions and revisions happen without unnecessary blockchain popups Seamless UX for both freelancers and clients 🎯 What People Can Use It For FairDeal can be used for: 💻 Freelance development projects 🎨 Graphic design and digital art commissions ✍️ Content writing and media production 🧠 Consulting and technical audits 🪙 NFT and Web3 creative collaborations 🚀 Impact FairDeal makes freelance transactions safer, transparent, and trustless. It protects both money and intellectual property while removing intermediaries and reducing platform fees. By combining decentralized escrow, encrypted file sharing, and automated workflows, FairDeal enables secure peer-to-peer collaboration in the digital economy.

Problem Training AI models requires large amounts of human-labeled data, but current data labeling platforms are centralized, take high commissions, and lack transparency in how tasks are evaluated and paid. Workers often receive low compensation, while companies struggle with trust, fairness, and efficient global participation. Solution SolveMint is a decentralized platform where companies can post AI data labeling tasks and lock rewards in a smart contract. Workers complete these micro-tasks, and once a majority consensus is reached, the smart contract automatically distributes rewards to the correct contributors. This creates a transparent, fair, and global marketplace for AI data labeling powered by Web3.
