EVM Chains API

healthy 3,400 Subscribers

A live directory of every EVM-compatible blockchain, keyless. Look up any chain by its chain ID or by name and get its native currency, public RPC endpoints, block explorers, info URL, faucets and testnet flag; search the 2,600+ networks; or just get a chain working public RPC URLs. The networks / chain-ID layer for wallets, dapps, RPC routers, block explorers and multi-chain tooling. Live, nothing stored beyond a short cache. Backed by the open chainid.network (ethereum-lists/chains) registry.

Morph Chain API

Real-time on-chain data for Morph (chain-id 2818), a consumer-focused Ethereum Layer-2 built on an optimistic-zkEVM hybrid rollup, where gas is paid in ETH. The status endpoint returns the chain id, network id, latest block height, native symbol and node client version so you can confirm the chain is live and synced. The block endpoint returns a block by decimal or 0x-hex height — or the latest block when no height is given — with its hash, parent hash, timestamp (raw and ISO), transaction count, gas used and limit, base fee and miner. The gas endpoint returns the current gas price in both wei and gwei at the latest block. The balance endpoint returns the native ETH balance (in wei and human-readable units) and the transaction count (nonce) for any 0x address. The meta endpoint documents the chain id, decimals and ecosystem. Reads a live Morph JSON-RPC node directly, so values are current to the latest block. Live, nothing stored. 5 endpoints. This serves native-coin and chain data; for ERC-20 token balances or contract calls use a dedicated token/contract API.

Boba Network Chain API

Real-time on-chain data for Boba Network (chain-id 288), an Optimistic-Rollup Ethereum Layer-2 scaling solution where gas is paid in ETH (the BOBA token is a separate ecosystem ERC-20). The status endpoint returns the chain id, network id, latest block height, native symbol and node client version so you can confirm the chain is live and synced. The block endpoint returns a block by decimal or 0x-hex height — or the latest block when no height is given — with its hash, parent hash, timestamp (raw and ISO), transaction count, gas used and limit, base fee and miner. The gas endpoint returns the current gas price in both wei and gwei at the latest block. The balance endpoint returns the native ETH balance (in wei and human-readable units) and the transaction count (nonce) for any 0x address. The meta endpoint documents the chain id, decimals and ecosystem. Reads a live Boba JSON-RPC node directly, so values are current to the latest block. Live, nothing stored. 5 endpoints. This serves native-coin and chain data; for ERC-20 token balances (including the BOBA token) or contract calls use a dedicated token/contract API.

Canto Chain API

Real-time on-chain data for Canto (chain-id 7700), a permissionless, public-good EVM-compatible Layer-1 built on the Cosmos SDK with Ethermint and focused on free public DeFi infrastructure with CANTO as its native coin. The status endpoint returns the chain id, network id, latest block height, native symbol and node client version so you can confirm the chain is live and synced. The block endpoint returns a block by decimal or 0x-hex height — or the latest block when no height is given — with its hash, parent hash, timestamp (raw and ISO), transaction count, gas used and limit, base fee and miner. The gas endpoint returns the current gas price in both wei and gwei at the latest block. The balance endpoint returns the native CANTO balance (in wei and human-readable units) and the transaction count (nonce) for any 0x address. The meta endpoint documents the chain id, decimals and ecosystem. Reads a live Canto JSON-RPC node directly, so values are current to the latest block. Live, nothing stored. 5 endpoints. This serves native-coin and chain data; for ERC-20 token balances or contract calls use a dedicated token/contract API.

Moonriver API

Real-time on-chain data for Moonriver (chain-id 1285) — the Ethereum-compatible companion network to Moonbeam, deployed on Kusama, with MOVR as its native token. Query live network status (latest block height, network id, client version), fetch any block by height or the latest one (timestamp, transaction count, gas used / limit, base fee, miner), read the current gas price in wei and gwei, and look up the native MOVR balance and transaction count of any address. A keyless, no-account JSON wrapper over the canonical Moonriver JSON-RPC node — decoded from hex into plain decimals and human-readable MOVR so you do not have to. Ideal for explorers, wallets, dashboards, gas estimators and analytics on Moonriver.
