The Problem

If you're using eth-rpc-errors in your project,
you might not have noticed something concerning —
the package hasn't been maintained in over 5 years.

Yet it still gets 850,000+ weekly downloads.

That means hundreds of thousands of Ethereum projects
are depending on an abandoned package. No bug fixes.
No security patches. No responses to issues.

Even MetaMask — the original creators — have moved
away from it to @metamask/rpc-errors.

The Solution

I forked it and have been actively maintaining it as:

👉 eth-rpc-errors-maintained

Migration: One Line

This is genuinely the easiest migration you'll ever do.

Uninstall the old package:

bash
npm uninstall eth-rpc-errors
npm install eth-rpc-errors-maintained
