- Five Ideas You Could Actually Build on COTI
For years, Web3 has told people to "just build." But behind that simple advice is a hard truth that building in crypto has never been easy. New builders face a lot of things like first, there's the technical barrier. You need to understand Solidity, smart contracts, deployment frameworks, wallet integrations, tokenomics, backend logic, frontend UX, and security best practices. That alone filters out 90% of creative people who might otherwise have strong ideas. Then there's funding. Even if someone manages to build something functional, launching requires liquidity, marketing exposure, and community traction. Without these, projects die quietly. Many good ideas never see daylight simply because the founders lack capital or visibility.
And even if you overcome those two obstacles, there's privacy. Traditional blockchains expose everything by default. User balances, transaction amounts, smart contract logic - all visible. For many real-world use cases, that transparency becomes a barrier rather than a benefit. So the ecosystem ends up with what's easiest to build: forks, clones, speculative tokens, and meme-based experiments. What we don't get enough of are serious privacy-first applications that solve real problems. That's exactly the gap COTI is addressing.
The Stay.COTI program attempts to remove the friction that has kept builders on the sidelines and to prove that privacy-first applications can be launched fast, even by non-developers. COTI is essentially saying that you don't need a dev team, you don't need VC funding, and you don't need years of blockchain experience. If you have an idea and the willingness to execute, you can ship something real. And if you do it well, you can earn up to 50,000 COTI - plus ecosystem support that most early builders can only dream of.
What Is Stay.coti and Vibe Coding
Stay.COTI is a no-code, AI-assisted platform purpose-built for creating dApps on COTI V2, a privacy-centric, Ethereum-compatible Layer 2. It is designed to empower builders of all backgrounds, enabling them to deploy decentralized applications without the steep learning curve of traditional blockchain development. "Vibe coding" sounds intaresting? It's a program under stay.coti . With stay.coti, instead of writing complex smart contract code line by line, builders use structured AI-powered prompt packs and guided workflows to generate and deploy applications. Think of it as an AI-assisted building, where the heavy lifting of code scaffolding and deployment is vanished or simplified. Projects can include:
- Private backends or databases
- Games with private logic or state
- User-centric apps with confidential data
- Privacy-aware smart contracts
- AI + privacy use cases
But you still need a real concept and need to think about how your app works, how your token functions, and how users interact with it. But you don’t need to fight with every technical detail just to get started. A well known COTI's ambassador Soeren Jensen put it perfectly,
In the current COTI Vibe Coding Challenge program, the process follows three clear stages: build your app or game, mint your private token, and connect the token to your project. By the end, you don’t just have a prototype. You have something live, functional, and usable. Instead of spending months preparing to build, you can start building immediately. Instead of stopping at an idea, you can launch.
Submission Procedure
Every participant must mint and connect a privacy token to their app. That means the build becomes a complete economic system, The submission requirements are below:
- Vibe Code an app or game using COTI privacy features
- Mint & connect a privacy token to your app
- Share a demo on X and include a link
- Fill out the submission form
- The deadline is March 13th, 2026.
But beyond prizes, this is about ecosystem growth. It's about onboarding creators who previously felt locked out.
The Rewards: More Than Just 50,000 COTI
Yes, 50,000 COTI is a serious prize. For many builders, that alone is enough reason to participate. But the real value goes beyond the number. The first-place winner doesn’t just walk away with tokens. The project gets support to actually grow inside the COTI ecosystem. That includes a Liquidity Kickstart on Bancor, placement in the COTI ecosystem, a feature on the COTI Privacy Paradigm livestream, and ongoing marketing support from the team.
For early-stage builders, that kind of backing can matter more than the reward itself. Launching is hard and on the other hand getting attention is harder. Many projects fail not because the idea is weak, but because no one hears about it. COTI is offering visibility, structure, and continued support. That gives the winning project a real chance to move forward instead of fading after the competition ends.
Second and third place also receive meaningful rewards ~ 25,000 and 10,000 COTI. That’s enough to fund further development, expand features, or build community incentives. There are also weekly Vibe Builder livestreams during the campaign. These sessions walk participants through demos, explain privacy best practices, and help solve real build challenges. There’s guidance along the way, so while the headline says 50,000 COTI, but behind the scene, COTI is helping builders turn an idea into something real and giving them a platform to grow after launch.
Five Ideas You Could Actually Build on COTI
Below are five practical ideas that fit naturally with COTI’s privacy-focused infrastructure. Each one is realistic, usable, and designed around what COTI does best: confidential logic, private data, and token-powered applications.
1. Private Prediction Market for Sensitive Topics
What It Is:
A prediction platform where users can place stakes on events without exposing their identity, position. This could include industry outcomes, governance decisions, investigative topics, or high-risk discussions where public exposure would discourage participation.
Why COTI Is a Fit:
COTI’s privacy layer allows transaction details and user data to remain confidential while still verifying that outcomes are processed correctly. This means users can participate without broadcasting their activity to the entire network.
How It Could Work:
Users connect a wallet, receive a privacy token, and place predictions through a confidential smart contract. The system calculates outcomes privately and distributes rewards automatically. Only the final result is visible, not individual positions or identities.
2. Quantum-Resistant Escrow for Real-World Contracts
What It Is:
A smart escrow system that protects real-world transactions (real estate, deals, etc.) with quantum-resistant security.
Why COTI Is a Fit:
With future-proofing in mind, COTI can layer quantum-safe computation and keep agreements private. As institutions begin to worry about future cryptographic threats, privacy-preserving and forward-compatible systems will become increasingly valuable.
3. Anonymous Health Support Platform
What It Is:
A support platform where users can access counselors, coaches, or peer support anonymously and pay privately.
Why COTI Is a Fit:
Health-related interactions require discretion. Public blockchain records would discourage users. COTI ensures payment and user data remain confidential.
How It Could Work:
Users book sessions through a private smart contract. Payments are processed using a privacy token. Session confirmations are verified on-chain without revealing personal information or service details.
4. Confidential DAO Voting Platform
What It Is:
A DAO voting tool where members can vote without exposing individual choices or token balances.
Why COTI Is a Fit:
Public voting can create pressure and bias. COTI allows voting logic to remain private while still ensuring the result is verifiable and accurate.
How It Could Work:
Members stake governance tokens and submit encrypted votes. The smart contract tallies results privately and publishes the final outcome. Individual votes remain hidden, reducing manipulation and social pressure.
5. Secret Auction Platform
What It Is:
An auction dApp where bids remain hidden until the auction ends, preventing front-running and overbidding.
Why COTI Is a Fit:
On public chains, auction bids are visible in mempools, giving competitors an unfair advantage. COTI keeps bid amounts confidential while enforcing rules on-chain.
How It Could Work:
Users submit encrypted bids using privacy tokens. The contract records bids confidentially. After the auction closes, the highest bid is decrypted and the winner gets the asset.
Why This Challenge Matters for the Entire Ecosystem
The Vibe Coding Challenge expands what’s possible on COTI and shows the world how accessible privacy-first development can be. Every app, game, or token launched through this challenge adds to the network’s utility, liquidity, and community engagement. For the ecosystem, this means more real use cases. Like, we’re seeing them applied in games, finance, and everyday apps. Each project that goes live becomes a working example of how COTI’s privacy features can be used, which encourages other builders to explore, experiment, and iterate. It also strengthens the COTI community. Builders, developers, and users are all part of the same growing network. When new projects launch, they bring in new users, create new ways for existing users to interact with the network, and provide feedback that helps improve the infrastructure itself.
Finally, it’s about proving that privacy-first applications don’t have to be complex or out of reach. This challenge demonstrates that with the right tools, anyone can build, launch, and deploy apps that respect user privacy while still being functional and engaging. Over time, these incremental additions create a robust ecosystem where ideas can grow, users can trust the network, and the infrastructure becomes a go-to platform for privacy-enabled innovation.
