Developed on Polkadot Substrate.

STONE Index is an open-sourced project with a few dependencies like Polkadot Parachain with Swap, Wrapped Assets, etc.

Thanks to Substrate’s forkless upgrades, the entire network is upgraded over time without fear of splitting the network. STONE index turns the concept of an index fund on its head. Instead of paying fees to portfolio managers to rebalance your portfolio, you collect fees from traders who rebalance your portfolio by following arbitrage opportunities.

Stone Index is a part of the broader development plan for the STONE-V2 product roadmap.
