Manta Network

Manta Network is a modular Layer-2 blockchain ecosystem for zero-knowledge (ZK) applications, comprising two complementary networks. Manta Pacific is an EVM-compatible Ethereum Layer-2 rollup built on the Optimism OP Stack that uses Celestia for modular data availability, giving developers low-gas deployment of ZK applications through the standard Ethereum JSON-RPC interface (chain ID 169). Manta Atlantic is a Polkadot parachain (Para ID 2104) focused on on-chain ZK identity and privacy, exposed through Substrate/Polkadot JSON-RPC over WebSocket. Developers build with familiar EVM tooling, deploy against a public Sepolia testnet and faucet, and interact with the network via public RPC endpoints, block explorers, and native bridges. Manta Network is backed by Polychain Capital and other investors.

Manta Network publishes 2 APIs on the APIs.io network. Tagged areas include Company, Layer 2, Blockchain, Ethereum, and EVM.

Manta Network’s developer surface includes documentation, API reference, getting-started guide, engineering blog, sandbox, and 10 more developer resources.

Create-or-Update Ergonomics could not be measured. We hold no machine-readable contract for this provider to read, so there is nothing to measure a write surface against. Excluded rather than scored zero: never-measured and measured-empty are different facts. Publishing an OpenAPI is what makes this facet — and several others — scorable at all.

Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from github.com/api-evangelist/manta-network: open an issue to ask a question, or submit a pull request to add artifacts.
