Meter

Meter is a high-performance, EVM-compatible Layer-1 blockchain and cross-chain infrastructure network built for the Web3 economy, backed by General Catalyst and Pantera Capital. Its HotStuff-based hybrid PoV consensus delivers thousands of TPS with instant finality, MEV/censorship resistance, and a metastable gas currency (MTR) pegged to energy alongside the MTRG governance token. Developers reach Meter through a standard Ethereum JSON-RPC endpoint (rpc.meter.io) that works with web3.js, ethers.js, Hardhat, Remix and MetaMask, and through a native RESTful node API ("Meterest") covering accounts, blocks, transactions, event/transfer logs, node status, staking and WebSocket subscriptions. The Meter Passport bridge provides generic cross-chain messaging and asset transfer, and the meterify library gives a web3.js-style adaptor to the native API.

Meter publishes 8 APIs on the APIs.io network, including Accounts API, Blocks API, Debug API, and 5 more. Tagged areas include Blockchain, Web3, Cryptocurrency, Layer-1, and EVM.

The Meter catalog on APIs.io includes 1 event-driven AsyncAPI specification.

Meter’s developer surface includes changelog, sandbox, documentation, API reference, getting-started guide, engineering blog, support, and 20 more developer resources.
