what's Aqua.fun?

Aqua.fun is a fully on-chain DrawFi and GameFi NFT project built on Soneium, an Ethereum Layer-2 blockchain developed by Sony Block Solutions Labs. Users create hand-sketched doodles of marine creatures, primarily fish, which are evaluated by AI for recognition accuracy. Sketches achieving sufficient confidence scores (e.g., over 60%) qualify for minting as upgradable NFTs, transforming casual drawings into collectible, evolving on-chain assets. These NFTs come with randomized abilities that enable passive generation of in-game GOLD, used for upgrades and enhancements. All mechanics—AI judging, minting, rewards, and evolutions—are transparently calculated on-chain, ensuring merit-based progression without gatekeeping, insider allocations, or opaque systems. Free drawing mode allows casual participation, while minting unlocks ownership and competitive GameFi elements open to everyone.[[1]](https://soneium.org/en/ecosystem)[[2]](https://x.com/i/status/2031262181682229520)
