Inspiration:

All of us have made commitments we didn’t keep. New Year's resolutions, a promise to not procrastinate next time, a gym pass we just couldn’t find the time to use. But, at the same time, we noticed that when money is on the line, especially money we put up for a challenge with friends, the task is definitely getting done.

So, what if sticking to your goals wasn't just a word-based promise, but you had real stake in it?

Most accountability tools rely on willpower, reminders, checklists, and streaks. They’re easy to ignore and anyways, what's the harm if you lose. Behavioral psychology research shows that the strongest motivator isn't hope, or even reward, its loss aversion. People work harder to avoid losing $50 than to earn $50.

Crypto gives us the perfect tool for this. A trustless, on-chain contract that enforces your commitments automatically, turning personal goals into social, stake-based challenges where success pays and failure costs.

To maximize motivation, we added social accountability. Public challenges make people want to show up even more, so we integrated Twitter/X into the flow: new public challenges are automatically shared with the community, challenge updates are posted regularly, and winners get a shout out. Pools can also be private, created for just a group of friends who want to better themselves together.

This project was born out of the universal feeling of wanting to become better and the frustration of knowing how easy it is to fall off. We wanted to build something that makes following through not just easier, but inevitable.

What It Does:

Our platform turns goals into stake-backed, on-chain accountability pools. Users can join and create lifestyle and crypto challenges (e.g., daily workout, learning streak, DCA investing), stake tokens, and commit to sharing their progress. Our autonomous AI agent monitors updates 24/7 and verifies proof using chain transactions for crypto challenges and XXX for lifestyle challenges. At the end of the challenge, smart contracts distribute the pool: those who stayed consistent share the rewards; those who didn’t lose their stake.

The result is a game-like system where accountability becomes

Public (your progress is visible)
Objective (the rules are clear)
Automated (no manual review, no middle man, no opting out)

A Use Case Everyone:

One of CommitMint’s goals is to bring in new people to the crypto space. Since everyone, not just those already in the crypto space, can benefit from accountability, we prioritized making the UX simple and with those who are not already in the crypto world in mind. The UI features simple and plain text with instructions and tutorials embedded throughout. The UX is structured in a way to abstract away blockchain complexity. For the users new to the space who don’t want to understand wallets, transactions, or smart contracts, they don’t need to; they can just focus on participating and seeing results.

For the crypto natives, CommitMint adds a layer of financial gamification. Users can create DCA or staking challenges where success grows their holdings and failures risk their stake. Crypto-forward friend groups can also create challenges around maintaining risk limits or diversifying investments. The on-chain verification ensures no manual intervention is needed. Crypto users will enjoy seeing measurable outcomes in the form of token redistribution, which turns abstract goals into tangible, tradable rewards.

App Expansion

The public nature of the app helps it naturally spread, creating a socially self-propagating advertisement strategy. Each user, regardless of prior crypto knowledge, acts as a brand ambassador simply by creating and participating in challenges. This self-propagating loop allows CommitMint to reach users who may have never interacted with blockchain before, introducing them to Solana in a natural, engaging way.

How We Built CommitMint:

On-Chain Layer:

We wrote a custom Anchor program on Solana that manages the full commitment lifecycle:

Pool creation: Dynamic instantiation of PDAs uniquely derived from challenge parameters
Stake locking: Secure token transfers using SPL Associated Token Accounts + CPI calls
Progress tracking: On-chain state tracks “verified days,” streak violations, and eligibility
Deterministic payout: Fair-share redistribution using a weighted reward mechanism, validated with time-window logic _ This ensures that the protocol is trustless and transparent, with no manual intervention required. _

Verification Engine:

We wrote a system that ensures goals are tracked objectively:

Smart contracts: Anchor + Solana
Backend: FastAPI + Supabase for challenge metadata, user state, and AI integration
AI Agent: Python-based, monitors progress, verifies uploaded evidence or API data
Frontend: Next.js + TypeScript with responsive, beginner-friendly UI _Together, these pieces create an end-to-end loop that prioritizes onboarding users as fast and easily as possible. _

Challenges We Ran Into:

Twitter posting: Rate limit issues, duplicate posts
Designing incentives: Ensuring fairness, preventing cheating, and only supporting challenges that can be objectively verified while keeping it easy for users to create and join challenges
Cross-Platform Integration: Coordinating blockchain, backend, frontend, AI agent, and social APIs in real time
Deployment issues and coordinating all the frontend, backend, agent, and smart contract changes. Implementing blinks to correctly allow users to join challenges directly from Twitter.

What We Learned

UX is critical: Users don’t care about smart contract mechanics; simplicity drives adoption
Social incentives are powerful: Public accountability and recognition dramatically improve participation
Blockchain is reliable but needs orchestration: Synchronizing on-chain data with off-chain logic is tricky but essential

Accomplishments We’re Proud Of

Fully autonomous accountability protocol
Fully autonomous advertising via social sharing
Built for both crypto-native and non-crypto users
Solves a real-world problem that affects virtually everyone
Demonstrates a working stake-based motivation system with measurable outcomes

TL;DR:

CommitMint merges behavioral psychology, on-chain smart contracts, and social incentives to make following through on commitments trustless, stake-based, and rewarding. By automating accountability through smart contracts, integrating AI verification, and leveraging public/private challenge pools, the platform ensures that success is rewarded, failure has tangible consequences, and user engagement is maximized.

We’re excited to continue expanding: more challenge types, improved AI verification, leaderboards, and tokenomics. CommitMint is the first step toward making goal achievement inevitable, social, and fun.
