$INDEX Token: Trading Fees Fund Tokenized Stock Distributions

The Index is a Robinhood Chain application and ERC-20 token that converts secondary-market trading activity in $INDEX into automated distributions of tokenized stock instruments for eligible holders. The protocol routes a trade fee into ETH, uses that ETH to purchase an equal-weight basket of tokenized stocks, and sends the resulting assets directly to qualifying wallets.

The project's core problem statement is narrow but unusual: rather than asking users to stake, manually claim, or subscribe to an actively managed vault, The Index has a 3% ETH fee on trades that funds distributions to eligible holders. DefiLlama classifies it as a Robinhood Chain protocol suite that converts trading fees into tokenized stock distributions.

The Index emerged in 2026, shortly after Robinhood Chain moved from the announced and testnet phase into public mainnet production. The project's own official site describes the mechanism, while DefiLlama's adapter describes coverage across four historical $INDEX distributors, Earn-a-Stock V1 and V2 reward vaults, and multiple Index Treasury factories.
