Show HN: ForkOff – Live Fork and RPC Desync Monitor for Ethereum and L2s

1 ForkOff 0 6/9/2025, 8:30:12 PM

I built ForkOff https://forkoff.io to monitor block height desyncs across Ethereum and major L2s (Base, Arbitrum, Optimism, etc).

It polls pairs of public RPC endpoints every 30 seconds and flags any divergence that could indicate a fork risk.

Features: - Live status table showing block differences and sync status - Reliability tracking (success/failure counts) - CSV export + simple API (for devs or dashboards) - Covers 8+ major chains, more coming

It's lightweight, anonymous, and free to use. No wallets, no cookies, no BS.

I'm open to feedback, ideas, contributors — and curious if anyone would find this useful for ops, tooling, or infra alerts.
