L2BEAT Rollup Risk & TVS API

healthy 3,286 Subscribers

Live Ethereum layer-2 / rollup risk and value-secured data from L2BEAT — no key, nothing stored. L2BEAT's signature is its independent risk framework: every rollup is rated by maturity Stage (Stage 0 / 1 / 2) and assessed across the canonical risk dimensions — sequencer failure, state validation, data availability, exit window and proposer failure — each carrying a good / warning / bad sentiment and a plain-language explanation. This is the rollup-risk and total-value-secured (TVS) view, distinct from the L2 economics/fundamentals and the on-chain per-chain APIs in the catalogue. The projects endpoint lists every tracked L2 with its type (Optimistic Rollup, ZK Rollup, Validium, layer3…), category, host chain, maturity Stage, TVS and 7-day change. The project endpoint returns one rollup in full — the TVS breakdown (native / canonical / external, and ether / stablecoin / btc / other), the Stage, providers, purposes and the complete risk assessment. The risks endpoint returns just the risk rosette for a rollup with a sentiment tally. The summary endpoint aggregates the whole ecosystem — total TVS, project count and the distribution by Stage and by type. More than a hundred rollups tracked, updated live. Project lookup is by slug (arbitrum, base, optimism, zksync-era, scroll, linea, starknet).

WEMIX API

Live EVM on-chain data for WEMIX (chain id 1111) — the gaming-focused public Layer-1 built by Wemade, whose native token is WEMIX — served directly from public EVM JSON-RPC nodes with multi-node failover. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size. The gas endpoint returns the current gas price in both wei and gwei. The balance endpoint returns the WEMIX balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole WEMIX with exact big-integer scaling. Every figure is read live from the chain over JSON-RPC — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for explorers, wallet and dashboard tooling, gas trackers, address monitors and game-economy analytics across the WEMIX ecosystem. Live keyless upstream. 5 endpoints.

Monad API

Live EVM on-chain data for Monad (chain id 143) — the high-performance, parallel-execution Layer-1 designed for thousands of transactions per second, whose native token is MON — served directly from public EVM JSON-RPC nodes with multi-node failover. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size. The gas endpoint returns the current gas price in both wei and gwei. The balance endpoint returns the MON balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole MON with exact big-integer scaling. Every figure is read live from the chain over JSON-RPC — nothing bundled or modelled — behind a short server-side cache with keep-warm so the feed stays fast and fresh. Ideal for explorers, wallet and dashboard tooling, gas trackers, address monitors and analytics apps across the Monad ecosystem. Live keyless upstream. 5 endpoints.

Superposition API

Live EVM on-chain data for Superposition (chain id 55244) — an Arbitrum-Orbit DeFi Layer-3 with ETH gas and on-chain yield-bearing Super Assets — served directly from the public Superposition JSON-RPC with server-side resilience. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size. The gas endpoint returns the current gas price in both wei and gwei. The balance endpoint returns the ETH balance and outgoing transaction count for any address, converted from base wei (18 decimals) into whole ETH with exact big-integer scaling.

Live EVM on-chain data for Matchain (chain id 698) — the BNB-Chain-secured Layer-2 focused on decentralised identity and social, where gas is paid in BNB — served directly from the public Matchain JSON-RPC with server-side resilience. The status endpoint returns the chain and network id, the latest block height and the node client version. The block endpoint returns a block by number (or the latest) with its hash, parent hash, timestamp, transaction count, gas used and gas limit, miner and size.
