# Alchemy Client and API Routing Patterns

## Overview

Route Alchemy work to viem, direct Data APIs, Wallet APIs v5, or Solana Web3.js without reviving the archived SDK. 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

There is no single current JavaScript Alchemy SDK for every product. EVM Node reads belong behind a `viem` transport adapter, Data APIs behind response-contract adapters, transacting applications behind Wallet APIs v5, and Solana behind Solana Web3.js. The archived `alchemy-sdk` is migration input, not a new architecture choice.
