# RSS3 Chain API
> Live on-chain data for the RSS3 Value Sublayer (VSL) mainnet (the EVM chain of the RSS3 Open Information Layer, native RSS3) via Blockscout — no key. Read network stats (block height, total transactions, gas), a gas oracle in gwei, the most recent blocks and full block detail by height or hash, any address balance and contract info, full transaction detail, ERC-20 token detail by contract, and a universal search across addresses, tokens, blocks and transactions. Real chain data with the rotating proxy as automatic fallback — 9 endpoints. Ideal for wallets, explorers, data/social-graph tooling, portfolio trackers and on-chain monitoring on RSS3.
