# Alchemy Read-Only Connectivity Proof
## Overview
Build a minimal, reviewable Alchemy EVM read with viem and prove its network, authentication, and failure behavior. This workflow produces a reviewable artifact and negative-path evidence before any live side effect.
## Prerequisites
- Current first-party Alchemy documentation for the selected product, chain, feature, client, authentication method, limit, and lifecycle.
- Named product, application, security, data/privacy, budget, release, and operations owners appropriate to the requested scope.
- Synthetic or approved non-production fixtures, a credential canary, explicit success criteria, and a tested rollback boundary.
## Current Contract
The current Ethereum quickstart uses `viem`. A successful `eth_blockNumber` proves endpoint connectivity only; it does not prove Enhanced API, NFT API, Portfolio, Wallet API, or Admin entitlement. Chain identity must be checked from the response context rather than assumed from an endpoint string.
