TrusToken & Autonomous Vehicle (Seperate)

Inspiration 🌍

TrusToken Many people want to live more sustainable and give back to their community. But often, these actions go unrewarded, hard to track, or easy to fake when rewards do exist. Due to this lack of trust and motivation, this becomes difficult sustainability programs to scale.

TrusToken was created to solve this. By turning real-world actions into AI-verified, on-chain impact credits issued as NFTs, we aim to make sustainable behavior trustworthy, motivating, and scalable.

What it does 🔐

TrusToken Trustoken is a blockchain-powered trust verification platform that allows users to issue, verify, and claim trust-based credentials as NFTs. Instead of relying on centralized databases or screenshots, users can prove achievements, roles, or contributions using cryptographically verifiable tokens. These tokens act as digital trust badges that can be shared, verified, and tracked on-chain.

Trustoken enables:

Issuers to mint verified trust tokens
Users to claim and store their credentials
Verifiers to instantly check authenticity

Which creates a transparent, decentralized network that works across platforms.

27-Glacier Brainstorming: We scoped out the robot course, measured the dimensions needed, and focused on the constraint of being only given 2 wheels Prototype: We used tape and secured most components except for the sensors to the board, giving us to test out the car while not making permanent changes. However, we still have to permanently fix the wheel motors to the chassis as we had to work around missing screws for the first few ours Color sensor: We then attached the colour sensor, giving us a chance to have a working prototype of the path following algorithm before we worked on anything else Ultrasonic sensor & the arm: The installation of these parts came naturally, except for the repositioning of the breadboard, as we had to separate it to accommodate for the orientation of the ultrasonic sensor

How we built it ⚙️

Our web platform allows organizations, communities, and individuals to issue and verify Trustokens. Users can connect their wallet, view credentials, and verify others in seconds. Here’s the tech stack that made it possible:

React – Frontend dashboard for viewing and verifying credentials
Node.js – Backend logic and Solana transaction handling
Solana – Blockchain used to mint and store Trustokens
Gemini API – AI-based analysis of submitted proof and claims
Metaplex – NFT minting and metadata management

Challenges we ran into 🤔

Mandatory billing for Gemini API
Setting up the wallet for Solana
Designing a trust system that prevents fake claims while remaining decentralized
Learning smart contract development and security best practices on Solana
Working with .env was a challenge

Accomplishments that we're proud of 😊

Successfully deployed a Solana-based trust credential system that mints and verifies NFTs on-chain
Built an end-to-end verification pipeline, from AI-based evidence analysis to on-chain credential proof
Turned digital trust into a usable platform
