Manta Pacific RPC Endpoint

Fast, flat-rate Manta Pacific RPC node provider — free tier, no KYC, HTTP & WebSocket.

Manta Pacific is an EVM-compatible Ethereum Layer 2 built on the OP Stack that uses Celestia for modular data availability, operating as a validium. It uses ETH as its gas token and targets low-cost smart contract execution, with an emphasis on zero-knowledge applications.

About Manta Pacific

Manta Pacific launched its mainnet alpha on September 12, 2023 from Manta Network, a project backed by Polychain and others. It began with Ethereum for data availability and, in December 2023, migrated to Celestia for modular DA, which turns the rollup into a validium and lowers data-posting costs.

The network is an optimistic rollup using the OP Stack and is EVM-compatible, so standard Solidity tooling such as Foundry, Hardhat, ethers.js, and viem works without modification. ETH is the gas token, while MANTA serves as the ecosystem's governance and utility token. Manta Pacific positions itself for zero-knowledge applications via its Universal Circuits work.

Common Use Cases on Manta Pacific
