RWAvenue is a Web3 marketplace focused on tokenizing Real-World Assets (RWAs). Our mission is to connect traditional assets such as real estate, art, precious metals, and financial assets with blockchain technology. We have completed our initial MVP and are now expanding the platform into a scalable marketplace that enables secure digital ownership and management of real-world assets.

Description: APAX is a platform for tokenizing physical precious metals on EVM with a strong compliance focus. The Next.js UI is mostly built, but much of it still runs on mocked data. We need a full stack developer to finish the Node.js and Express backend, connect MongoDB, implement JWT authentication, and wire the frontend to live APIs so login and the dashboard use real data. Web3 and Solidity are out of scope for this phase. Timeline is about four to six weeks. Whitepaper: https://docs.google.com/document/d/17EIeQJWhz4Lt10gEVmWsEiRhKf8u-cfR/edit

# Project Overview Premium Haztrak is a modern environmental compliance platform designed to help organizations manage hazardous-waste tracking, electronic manifest workflows, and regulatory compliance records in a more secure, transparent, and legally defensible way, specifially designed for Office of Chief Counsel, PA Department of Environmental Protection, USA. The platform is built around hazardous-waste cradle-to-grave tracking, allowing generators, transporters, facilities, compliance teams, and legal professionals to manage key records, shipment events, supporting documents, signatures, corrections, and audit history in one structured system. The next phase of the project will introduce blockchain-based verification to strengthen record integrity, chain of custody, and regulatory audit readiness without exposing sensitive compliance data on-chain. # Current Version Status The current version provides the foundation for electronic hazardous-waste tracking and demonstrates how a digital system can support EPA e-Manifest and RCRAInfo-related workflows. At this stage, the platform focuses on core hazardous-waste record management, including manifest-related workflows, shipment tracking concepts, compliance documentation, and integration patterns for working with official environmental systems. The current system should be treated as the base layer for a more advanced compliance product. The goal now is to expand it into a premium version with stronger legal, audit, and verification capabilities. # New Integration Goals The main enhancement will be a blockchain-powered compliance verification layer. This blockchain layer will not store private hazardous-waste records directly on-chain. Instead, the system will generate cryptographic proofs for important documents and events, then anchor those proofs to blockchain so records can be independently verified later. # Key integration points include: Blockchain-based proof of manifest records Tamper-evident chain-of-custody tracking Hashing of documents, signatures, corrections, and shipment events Verifiable audit logs for regulatory and legal review Evidence packet generation for disputes, audits, or investigations Secure off-chain storage for sensitive data On-chain proof references for record integrity verification Compliance dashboard for high-risk, incomplete, or disputed records Core Product Features Premium Haztrak should include: Manifest and shipment management Organization and user role management Document upload and record storage Signature and approval tracking Correction and dispute history Chain-of-custody timeline Blockchain proof generation Verification page for documents and records Audit-ready PDF export Legal evidence packet generation Compliance activity dashboard Blockchain Integration Concept The blockchain component will work as a proof layer. When a critical event happens, such as a manifest being created, signed, corrected, received, or finalized, the system will generate a hash of that event or document. These hashes can be grouped and anchored to blockchain through a smart contract or verification registry. This allows a user, auditor, attorney, or regulator to later confirm whether a record matches the original verified version. The private data stays protected in the application database or secure storage. The blockchain only stores verification proofs. #Product Value Premium Haztrak improves environmental compliance by making records: More traceable More trustworthy Easier to audit Easier to verify Better prepared for legal review More resistant to tampering or undocumented changes The product is especially useful for organizations that need strong documentation, reliable compliance history, and defensible records in case of audits, enforcement questions, disputes, or litigation. #Long-Term Vision The long-term vision of Premium Haztrak is to become a trusted digital compliance layer for environmental records. Starting with hazardous-waste tracking and electronic manifest workflows, the platform can later expand into broader environmental compliance areas such as permits, inspections, remediation records, enforcement documentation, ESG reporting, and carbon-credit verification. Premium Haztrak’s goal is simple: To make environmental compliance records secure, traceable, verifiable, and legally defensible.

We're building a regulated real estate tokenization platform that converts institutional-grade properties into ERC-3643 security tokens with built-in ONCHAINID compliance. Our platform enables fractional ownership, secondary trading, and DeFi integration—making premium real estate investment accessible to everyone. I am looking for a talented blockchain $ smart contract developer. Tech Stack: - Blockchain: Solidity (ERC-3643 with ONCHAINID) on Arbitrum One, Hardhat - Backend: Node.js/TypeScript, Express, PostgreSQL, Redis - Frontend: React/TypeScript, ethers.js/wagmi, Tailwind - Infrastructure: AWS, Docker, GitHub Actions Blockchain Developer Responsibilities: - Design and deploy ERC-3643 smart contracts with compliance logic - Implement ONCHAINID identity and KYC whitelist integration - Coordinate external security audits and optimize gas usage - Build DeFi lending integrations (staking, yield, collateralization)

We need to connect a payment system to a high-risk site. The main requirements are the acceptance of fiat funds and the withdrawal of funds in cryptocurrency. Preferably no KYC. Only those who have had similar experience. Price is negotiable.
