# Alchemy Archived SDK Migration

## Overview

Migrate archived Alchemy JavaScript SDK integrations to current capability-specific clients with parity, canary, and rollback evidence. 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

`alchemy-sdk` is deprecated and its repository is archived. Current migration targets are capability-specific: `viem` for JavaScript EVM RPC, direct documented Data API adapters, `@alchemy/wallet-apis` for transacting apps and Portfolio support, and Solana Web3.js for Solana. Wallet APIs v5 has a separate first-party migration guide.
