Push Protocol

Push Protocol (formerly EPNS) is a Web3 communication and Layer 1 blockchain protocol that enables universal applications deployable once and accessible from any chain. Push Chain is the first true Universal Layer 1 blockchain offering 100% EVM compatibility, 4.2k TPS, 1-second native block time, and instant finality. The platform provides a JavaScript/TypeScript SDK (@pushchain/core) that wraps universal signing, cross-chain transaction routing, multichain execution, message signing, smart contract helpers, and utility functions. Developers can send universal transactions from Ethereum, Solana, BNB Chain, Base, and Arbitrum to Push Chain via a single SDK call, with fee abstraction allowing gas payment in any supported token (ETH, SOL, USDC, USDT). Push Chain also offers a testnet faucet (faucet.push.org) delivering 1 PC per address per 6 hours, and a UI Kit for React-based wallet and signer abstraction.

Push Protocol publishes 5 APIs on the APIs.io network. Tagged areas include Web3, Blockchain, Layer 1, Universal Apps, and Cross-Chain.

Push Protocol’s developer surface includes developer portal, documentation, getting-started guide, pricing, GitHub presence, engineering blog, and 10 more developer resources.

Regulatory Posture applies to this provider. Its tags matched the Payments regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

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.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

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/push-protocol: open an issue to ask a question, or submit a pull request to add artifacts.
