A Stellar-native freelance marketplace where work, escrow, and reputation are verifiable by default.
Live App | Demo Assets | Pitch Deck
Freelancers and clients still depend on traditional freelance platforms that keep payments, reputation, and dispute workflows inside private systems. This creates several trust gaps:
- Clients and freelancers rely on platform promises instead of verifiable settlement rules.
- Funds can be held in opaque internal ledgers instead of transparent escrow logic.
- Reputation is usually platform-owned, editable, and difficult to verify outside one marketplace.
- Cross-border payouts can be slow, expensive, or inaccessible for global talent.
- Proof of work, cancellations, revisions, and disputes are often scattered across off-platform tools.
Highrable is built for freelancers, clients, and marketplace operators who need payment protection, transparent work history, and safer collaboration across borders.
Highrable aims to make remote work more trustworthy by turning freelance agreements into verifiable workflows. The long-term vision is a global marketplace where:
- Clients can fund work with transparent escrow instead of relying only on platform custody.
- Freelancers can build portable, wallet-linked proof of completed work.
- Reputation can follow the worker across future marketplaces and applications.
- Cross-border payments settle through Stellar assets with lower friction.
- Disputes and edge cases remain auditable without hiding the core payment logic.
The team built Highrable to demonstrate how Stellar and Soroban can improve freelance marketplace trust. The project combines:
- Soroban smart contracts for escrow and reputation.
- Convex for fast product state, collaboration records, and admin operations.
- A Next.js web app for wallet onboarding, marketplace workflows, dashboards, profiles, disputes, and proof pages.
- Passkey smart-account support through
kalepail/smart-account-kit, making Stellar account flows easier for users who do not want to manage seed phrases directly.
- Freelancers who want faster cross-border payouts, stronger payment assurance, and verifiable work history.
- Clients who want to hire with escrow-backed confidence, milestone tracking, and better trust signals.
- Marketplace operators who need moderation, dispute review, admin controls, and contract-backed settlement workflows.
- Web3 builders and judges who want to inspect a full Stellar freelance marketplace implementation rather than only a smart contract demo.
- Escrow-backed marketplace: Clients can post jobs, review applicants, select freelancers, create escrows, fund escrows, and release payments after submitted work is approved.
- Soroban escrow contract: The escrow contract supports direct escrow creation, open escrow creation, create-and-fund flows, funding, freelancer assignment, proof submission, release, cancellation, dispute marking, dispute resolution, and asset allowlisting.
- On-chain reputation contract: Approved escrow releases can record immutable completion data, including escrow id, client, freelancer, asset, amount, job hash, rating, review hash, and freelancer aggregate stats.
- Passkey smart accounts: Highrable integrates
kalepail/smart-account-kitfor Stellar/Soroban smart-account wallet flows secured by WebAuthn passkeys, including creation, restoration, contract discovery, and smart-account mediated escrow actions. - Stellar wallet authentication: The app includes Stellar challenge/verify auth, wallet persistence, wallet session handling, and route guards for wallet-required flows.
- Stablecoin and asset support: Highrable supports USDC-style Stellar asset configuration, Stellar Asset Contract usage, trustline readiness, stablecoin balance panels, optional XLM escrow support, and XLM-to-USDC top-up flows.
- Stellar Path Payments: Highrable uses Stellar path payments so users can top up or convert from XLM into the configured USDC-style escrow asset before funding work, reducing friction for users who hold XLM but need stablecoin liquidity for marketplace payments.
- Marketplace safety tools: Listings can be sorted by safety, filtered by funded status, checked for scam signals, reported by users, and shown with trust/safety warnings before freelancers apply.
- Applications and milestone projects: Freelancers can submit proposals, showcase previous verified work, and apply to micro-gig or milestone-based jobs.
- Dashboards: Freelancer and client dashboard modes summarize income, pending balances, recent payouts, applied jobs, ongoing jobs, posted jobs, and deadline notifications.
- Public profiles: Freelancer profiles show wallet-linked identity and reputation. Client trust profiles show reliability indicators, recent jobs, completed payments, funded escrows, and reported jobs.
- Work agreements and submissions: Work agreements, agreement versions, work submissions, proof hashes, revision requests, deadline reminders, and notifications support the delivery lifecycle.
- Attachments and chat: Protected attachments, access logs, conversations, messages, read tracking, and evidence records keep collaboration inside the platform.
- Disputes and cancellations: Users can request cancellations, open disputes, attach evidence, respond in dispute threads, retry on-chain dispute marking, and inspect dispute timelines.
- Admin operations: Admin wallets can access metrics, dispute queues, dispute detail pages, moderation notes, status updates, and settlement recording APIs.
- Public proof pages: Escrow proof pages expose completed work details, proof status, reputation context, timeline entries, and share actions.
