Helios is an ETF-native Layer 1 blockchain designed to secure, automate, and deploy multi-chain portfolios natively on-chain. It enables the creation of on-chain ETFs, index products, and yield baskets backed by diversified assets such as ETH, BTC, BNB, and stablecoins. Through its inter-chain Proof of Smart Reserves consensus, these asset baskets both secure the network and generate yield, while native automation modules handle rebalancing and cross-chain execution without manual management.
