Manta Pacific RPC Endpoint

Flat-rate Manta Pacific RPC provider and Manta Pacific RPC node access: free tier, no KYC, HTTP & WebSocket. Manta Pacific mainnet chain ID 169.

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

• EVM smart contract deployment
• Low-cost DeFi applications

Manta Pacific Ecosystem

The Manta Pacific ecosystem includes DeFi and infrastructure projects such as iZUMi, LayerBank, and QuickSwap, alongside oracle and bridge integrations from providers like Pyth.

Manta Pacific guides from the blog

• Manta Pacific RPC: An OP Stack L2 on Celestia DAManta Pacific is an EVM OP Stack L2 (chain ID 169) that posts its data availability to Celestia instead of Ethereum — making it a validium, and making it cheap. It's standard EVM (viem/ethers/foundry work), with ETH gas and a ~7-day optimistic withdrawal window. Here's the developer map, including what modular DA changes about how you reason on security.
