# MCH Verse Chain API
> Live on-chain data for MCH Verse mainnet (the My Crypto Heroes gaming Verse-Layer L2 on Oasys, native OAS) 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/game-token detail by contract, and a universal search across addresses, tokens, blocks and transactions. Real Layer-2 chain data with the rotating proxy as automatic fallback — 9 endpoints. Ideal for wallets, explorers, game and NFT tooling, portfolio trackers and on-chain monitoring on MCH Verse.
