Find Blockchain Projects with Vollna

I’m ready to add blockchain utility to my existing PC game by giving players a real, on-chain trading marketplace for collectible items. The core requirement is straightforward: connect the game client to a smart-contract–powered backend so every collectible can be minted, listed, bought, and sold seamlessly without leaving the game interface.

Here’s what I need from you:
• Smart contract(s) that mint and manage the collectible items, enforce royalties, and handle secure peer-to-peer trades.
• An in-game UI module (Unity or Unreal are both acceptable) that lets players connect a wallet, browse listings, and complete purchases or sales in just a few clicks.
• A lightweight web dashboard for off-game item management and secondary sales—think OpenSea-style basics, but branded for this title.
• Full integration with the existing game logic so ownership checks, item transfers, and inventory updates happen in real time.
• Step-by-step deployment documentation and short video walk-through, ensuring my team can reproduce the setup on staging and mainnet.

Acceptance criteria:
• A player can mint a new collectible directly from the game and see it appear in their connected wallet.
• Two test accounts can list, buy, and transfer an item; the change is reflected instantly in both wallets and in-game inventories.
• All transactions show on a public block explorer with correct metadata.
• No critical contract or UI errors in a 100-trade stress test.

If you’re comfortable working with Solidity (or a comparable chain’s language), wallet APIs, and game-engine scripting, I’d love to see how you’d tackle this.

My Windows 11 desktop app includes a cryptocurrency-payment module, and that module keeps crashing the moment a user tries to pay. The crash happens every time, so no transaction ever reaches the network. The payment layer is part of a custom integration (it isn’t a browser flow or web checkout) and runs natively inside the app.

I need someone who can:
• Analyse the crash logs, reproduce the fault, and isolate the root cause
• Patch or refactor the code so the payment process completes without exceptions
• Verify that the repaired build handles successive transactions safely on Windows 11

Please be comfortable working with wallet APIs, desktop-application debugging tools, and the usual blockchain libraries so we can move quickly from diagnosis to a stable release.

I run a Unity-based crypto game that mints and trades NFTs directly from the client. Two issues are hurting player retention and revenue:

• Initial load time is far too long. Players abandon the splash screen before the lobby even appears. I suspect bloated asset bundles and un-streamed textures, but I need an expert audit and concrete fixes—Addressables, CDN configuration, compression, whatever will get players in fast.
• Blockchain payments occasionally fail. A user clicks “Buy”, gas is deducted, yet the transaction never finalises and no NFT is assigned. The failure seems to happen around the signing / callback cycle with our smart-contract gateway. I need rock-solid transaction handling and clear user feedback so we never lose a sale.

Deliverables
1. A profiled report pinpointing the current load-time bottlenecks plus implemented code and project-settings changes that cut the initial load to an acceptable target (we’ll agree the exact second count together).
2. A refactored payment flow that retries gracefully, confirms on-chain success, and reconciles item delivery or refund without leaving the player in limbo.
3. Brief hand-off notes outlining what was changed and how to keep things optimised going forward.

If you’re comfortable with Unity performance tooling, Addressables, async scene loading, ERC-721 / ERC-1155 interaction and Web3 wallets, I’d like to get started right away.

VTS Labs is not a typical dev shop.
We build next-generation software — Web3/blockchain platforms, AI systems, and high-complexity custom software for companies who need world-class engineering, not amateurs.
We want a marketer who can match that level.
We’re looking for a battle-tested, sharp-thinking, high-signal content strategist who can turn technical insights into authority-driving, founder-level thought leadership — primarily for LinkedIn.
If your idea of “content marketing” is Canva quotes, generic tips, or posting memes… this is not your job.
We want someone who understands tech, understands founders, and knows how to write content that punches through the noise and positions VTS Labs as the experts we are.


𝐘𝐨𝐮𝐫 𝐌𝐢𝐬𝐬𝐢𝐨𝐧
Create content that:
- Educates high-level buyers (founders, CTOs, VPs of Product)
- Positions VTS Labs as a premium AI & Web3 engineering partner
- Generates real inbound demand — not vanity likes
- Shows our technical depth without dumbing it down
You’ll publish 3–5 high-impact LinkedIn posts per week, sourced from conversations with the founder.
You will extract ideas, refine positioning, and build a consistent narrative around our strengths.
This role is about 𝐢𝐧𝐭𝐞𝐥𝐥𝐞𝐜𝐭𝐮𝐚𝐥 𝐟𝐢𝐫𝐞𝐩𝐨𝐰𝐞𝐫— not pretty graphics.

𝐖𝐡𝐚𝐭 𝐘𝐨𝐮 𝐖𝐢𝐥𝐥 𝐂𝐫𝐞𝐚𝐭𝐞
Expect to write content like:

This content should be 𝐩𝐮𝐧𝐜𝐡𝐲, 𝐩𝐫𝐚𝐜𝐭𝐢𝐜𝐚𝐥, 𝐨𝐩𝐢𝐧𝐢𝐨𝐧𝐚𝐭𝐞𝐝— and clearly coming from a company that knows what it’s doing.

𝐖𝐡𝐚𝐭 𝐘𝐨𝐮 𝐁𝐫𝐢𝐧𝐠
𝑴𝒖𝒔𝒕-𝑯𝒂𝒗𝒆𝒔
(Non-negotiable. Don’t apply without all three.)
- Proven experience writing thought leadership for technical or B2B founders

𝐇𝐮𝐠𝐞 𝐏𝐥𝐮𝐬 𝐈𝐟 𝐘𝐨𝐮 𝐇𝐚𝐯𝐞
- Hands-on familiarity with Web3/blockchain, smart contracts, DeFi, DAOs, L2s
- Experience writing about AI systems, LLM apps, model pipelines, or ML engineering
- Prior work with agencies, consultancies, or elite engineering teams
- Ability to challenge and push founders to articulate stronger ideas

We want someone who thinks like a strategist, writes like a founder, and communicates like an operator.

𝐃𝐞𝐥𝐢𝐯𝐞𝐫𝐚𝐛𝐥𝐞𝐬
- 3–5 high-authority LinkedIn posts per week
- Monthly content themes + narrative arcs
- Occasional long-form pieces (mini case studies, breakdowns, or thought pieces)
- Insight reports focused on quality of engagement (qualified followers, inbound conversations, credibility lift)

𝐖𝐡𝐚𝐭 𝐒𝐮𝐜𝐜𝐞𝐬𝐬 𝐋𝐨𝐨𝐤𝐬 𝐋𝐢𝐤𝐞
In 30–60 days:
- The founder’s LinkedIn becomes a top-of-feed voice on Web3, AI, and next-gen software delivery
- VTS Labs becomes clearly positioned as a premium engineering partner
- We start getting DMs, intros, and inbound leads directly from content
- Our content establishes us as the adult supervision in a market full of amateurs

• A short intro (keep it tight — sell yourself through clarity)
• 5 links to your strongest LinkedIn posts or founder-style content
• Your weekly or monthly rate
• A sample post (5–8 sentences) explaining: “What most founders misunderstand about building Web3, AI, or next-gen software — and how VTS Labs solves it.” If the sample feels generic or soft, we won’t move forward.

I’m finishing up a real-time Web3 game and need an experienced blockchain engineer to slot into our tiny, fast-moving team. The core engine—rendering, networking, and game logic—is already in place; what’s missing is the on-chain layer that turns it into a true metaverse experience.

Here’s what the role looks like day to day: you’ll design, code, and test smart contracts, hook them into our existing Python back-end, and expose everything to the front-end so players can transact seamlessly. Whether we deploy on Ethereum, Binance Smart Chain, Polygon, or a mix is still open for discussion, so your insight on trade-offs, gas optimisation, and security will heavily influence the final architecture.

Because the feature list ranges from NFT minting and trading to in-game item purchases and broader contract execution, I’m interested in someone comfortable jumping between solidity, web3.py, and the occasional Rust snippet when we experiment with sidechains. You’ll also help set up automated testing, basic audits, and deployment pipelines so we can push updates without drama.

Deliverables (all source under MIT licence):
• Production-ready smart contracts, fully unit-tested
• Integration layer for our Python/Django API and existing React front-end
• Simple CLI or script to automate contract deployment and upgrades
• Concise technical docs covering setup, functions, and security assumptions

Acceptance criteria: contracts pass test suite with >95 % coverage, mainnet-ready deployment succeeds on at least one EVM chain, and front-end calls resolve within target latency.

If you thrive on variety, enjoy solving tricky multi-domain problems, and like the idea of shaping a full-stack metaverse platform from the blockchain up, let’s build something awesome together.

Skills: JavaScript, Python, Software Architecture, Node.js, Blockchain, Ethereum, Solidity, Smart Contracts

Project Overview

We are building a next-generation blockchain lottery platform.
All randomness, odds, and payouts are already implemented on-chain and are provably fair.

This role is frontend only.

We are looking for a frontend interactive game or UI developer to turn our existing scratch cards into more engaging, game-style instant win experiences.

Important (please read)

You will NOT work on RNG, odds, payouts, or smart contracts

You will NOT change any backend logic

The win or lose result and prize amount are already decided and passed to the frontend

Your job is to design and build the visual reveal experience only

Think National Lottery instant win games, but built for a modern web platform.

What needs to be built

We currently have an Instant Wins or Scratch Cards page with four tiers:

Bronze

Silver

Gold

Platinum

Each ticket costs ten dollars and uses the same backend logic.

Instead of basic scratch-off UI, we want four different interactive reveal games, for example:

Pick a box

Flip cards

Smash tiles

Open treasure chests

Simple mini reels or wheel spin reveal

Each game:

Uses the same backend result

Is just a different visual way to reveal the outcome

Must feel smooth, modern, and fun

Technical details

Frontend only

HTML5 and JavaScript

React or Next.js compatible

Canvas, Phaser, PixiJS, or GSAP are all acceptable

Must be mobile friendly

Each game will receive a simple result object containing:

Whether the ticket won or lost

The prize amount

The tier

Your task is to animate and reveal that result.

Deliverables

Three to four interactive instant win reveal games

Clean, reusable frontend components

Clear win and lose states

Simple flow:

Select game

Play reveal

Show result

Play again or return to games

Design mockups and working frontend code are preferred.

Who this is for

This project is ideal for someone with experience in:

HTML5 mini games

Interactive web games

Casino, lottery, or instant win style frontends

Game-style UI animations

This project is NOT suitable for:

Backend developers

Blockchain or Solidity developers

Unity, Unreal, or mobile game developers

Pure graphic designers with no interactive work

How to apply

Please include:

Examples of interactive web games or mini games you have built

A short explanation of how you would approach turning scratch cards into game-style reveals

Applications without relevant examples will not be considered.
