Runtime package errors should use the SDK error hierarchy rooted at
@alchemy/common BaseError.
| Rule | When to read |
|---|---|
| BaseError | Before adding package runtime errors. |
| No plain Error | Before writing throw statements in packages/. |
| Raise footgun | Before using or modifying raise. |
packages/common/src/errors/BaseError.ts extends viem's BaseError..eslintrc forbids throw new Error(...) in packages/**/* except tests..eslintrc forbids import { BaseError } from "viem" to prevent accidentally
using viem's BaseError instead of @alchemy/common's.packages/wallet-apis/src/utils/schema.ts wraps Zod validation failures in
@alchemy/common BaseError.
