A fully on-chain ICP raffle dApp — transparent, verifiable, no off-chain tricks

Most meme or lottery-style tokens are vague about how things work behind the scenes, so I wanted to try something different, something that’s 100% transparent, verifiable, and actually lives fully on-chain.

That’s how Dvinity started: as a small community project built on the Internet Computer (ICP) using the ICRC-1 token standard, mostly as a learning journey that grew into a real on-chain application.

What makes it interesting (at least in my opinion) is that the entire raffle flow runs inside smart contracts (canisters).

• Randomness is generated on-chain
• All accounting happens on-chain
• Payouts execute after a winner claims the prize, verifiable on-chain
• No servers, cronjobs, or off-chain RNG scripts
• No hidden backend logic at all
Recently I added more features to make it fun and more utility-driven:
• Token-agnostic raffles (any ICRC token can be used)
• Daily + weekly draws
• On-chain burn mechanism tied to usage
• Staking mechanics
• A small “Mini DAO” module
• Completely free tickets for some raffles

This is not meant as a shill, just sharing something I’ve been building and learning from. If anyone has feedback, ideas, or criticism, feel free to drop it.
