Solana Print-on-Demand Platform

Job ID: 40098175

Budget: €250 – €750 EUR

Project Overview – On-Chain Print-On-Demand (Solana / USDC)
I’m building a fully on-chain, crypto-native print-on-demand platform where the entire checkout and settlement layer runs on USDC over the Solana network.
The core business flow mirrors classic POD—product customisation, order placement, automated fulfilment—but all monetary logic, incentives, and records live on-chain.
This is not just a Web2 store with a crypto payment button. The goal is a decentralised commerce layer where ownership, payments, rewards, and royalties are transparent, programmable, and composable.
Core User Flow
User selects a product (t-shirt, hoodie, cap, mug, etc.).
User customises it in real time (text, colours, image upload, positioning).
Wallet is connected (Phantom + Solana-compatible wallets).
Checkout happens exclusively in USDC (SPL token).
Funds are escrowed via a smart contract.
Order is pushed automatically to the fulfilment provider.
Order status updates are synced back on-chain.
Upon fulfilment confirmation, funds are released programmatically to suppliers and other stakeholders.
Web3-Native Features (Added & Important)
Token-Based Benefits
Free shipping for token holders (based on NFT ownership or SPL token balance).
Automatic discounts for verified holders (tiered by balance or NFT traits).
Token-gated products (exclusive designs only visible / purchasable to holders).
Optional loyalty rewards paid back in USDC or a project token.
Shipping & Pricing Logic
Shipping cost calculated off-chain but validated and finalised on-chain.
Shipping fee waived automatically if wallet meets holder criteria.
Transparent breakdown: base price, shipping, royalties, supplier cut.
Escrow & Royalties
Smart contract escrow holds funds until fulfilment state is confirmed.
Automatic payout split:
Supplier / fulfiller
Platform fee
Optional creator royalty (per design or collection)
Immutable on-chain record of:
Order ID
Product metadata hash
Wallet address
Payment amount
Royalty recipients
Technical Stack (Preferred)
Smart Contracts
Solana + Anchor (Rust)
SPL Token support (USDC now, extensible later)
Upgradeable program architecture
Events emitted for:
Order created
Payment received
Order fulfilled
Funds released
Dispute opened / resolved
Front-End
React / Next.js (TypeScript)
In-browser product personaliser (canvas/WebGL or similar)
Solana wallet adapter (Phantom + WalletConnect)
Real-time order & payment feedback
Mobile-first, responsive UI
Back-End / Bridge Layer
REST or GraphQL API
Listens to on-chain events
Syncs order data with fulfilment provider (POD API)
Pushes fulfilment status updates back on-chain
Minimal trust assumptions (stateless where possible)
Admin & Ops Dashboard
Order queue overview
Payment & escrow status
Fulfilment state tracking
Manual override tools (edge cases)
Dispute resolution interface (on-chain flags + admin actions)
Ability to:
Pause fulfilment
Refund orders
Resolve disputes
Milestone Deliverables (MVP)
Reviewed smart contract(s) deployed on:
Solana Devnet
Solana Mainnet-Beta
Event-driven bridge layer syncing blockchain ↔ fulfilment provider.
Production-ready front-end with:
Product personaliser
Wallet connection
USDC checkout
Admin dashboard for order & payment management.
Clear documentation, including:
Local development setup
Contract upgrade path
How to add additional SPL tokens later
How token-gated perks (free shipping, discounts) are configured
Development Style & Expectations
MVP deployed to devnet ASAP for supplier onboarding.
Clean commits, iterative pushes, and clear separation of concerns.
Security-first mindset (escrow, replays, fulfilment confirmations).
TypeScript-friendly tooling throughout.
If anything above needs clarification, I’m happy to refine the scope.
Please also share links to previous Solana / crypto-commerce projects you’ve worked on so I can review your code quality and architectural approach.
