Unipeg is an on-chain collectible project built around Uniswap v4 hooks, presenting uPEG as a new kind of on-chain object rather than a conventional NFT or token. Its collection features distinctive unicorn images generated entirely on-chain, without external storage or IPFS. Each image is associated with a specific integer amount of uPEG. When a swap occurs, the project’s custom hook produces a hash encoding visual details, including layers, colors, and the original owner. An SVG renderer uses that data to assemble each unique image, making its appearance a product of activity in the market.

The name combines “Uni,” “JPEG,” and “peg.” Unipeg describes a peg as a rule enforced at the point of exchange, reflecting the function its Uniswap v4 hook explores. Through its app, users can explore the collection and swap, while the project also supports peer-to-peer listing, discovery, and trading of uPEGs on Ethereum. Unipeg characterizes these transactions as non-custodial and without middlemen.
