# Error Handling
Runtime package errors should use the SDK error hierarchy rooted at
`@alchemy/common` `BaseError`.
## Rules
| Rule | When to read |
| ----------------------------------------- | ----------------------------------------------- |
| [BaseError](rules/base-error.md) | Before adding package runtime errors. |
| [No plain Error](rules/no-plain-error.md) | Before writing throw statements in `packages/`. |
| [Raise footgun](rules/raise-footgun.md) | Before using or modifying `raise`. |
## Evidence
- `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`.
