Perpetual futures on player market value.

Valoris is an on-chain perpetuals protocol where the underlying is a football player's market value (PMV). One liquidity pool per player, a 10× open-interest cap, and a price oracle — Kassandra — built to resist manipulation.

Built in the vocabulary of derivatives desks, not crypto marketing.

About

Honest status. Valoris is a research and proof-of-concept project, deployed on the Polygon Amoy testnet. Settlement on the testnet uses a mock token; production settlement is planned in a regulated, euro-denominated stablecoin (e.g. EURC) to match the EUR-denominated underlying and avoid FX basis. The contracts are not audited, the system is not registered or licensed, and nothing here is open to real capital. It is built simultaneously as an M.Sc. International Finance thesis and an early-stage protocol.
