How this tool works

Bridges hold or mint assets across networks, which concentrates value and has made them frequent attack targets. Most user losses come from fake bridge sites, wrong networks, wrapped tokens the destination app does not accept, or skipping a test transfer.

Tick each item as you confirm it. The tool tracks progress and flags the critical items you have not done yet.

Limits

  • Checks reduce, but cannot remove, bridge contract risk.
  • Nothing you tick leaves your browser.

Questions people ask

What is a crypto bridge?

A bridge moves value between blockchains, usually by locking an asset on one chain and issuing a representation on another, or by using liquidity on both sides.

Why are bridges risky?

They often hold large pools of locked assets or depend on a small set of signers or validators, so a single bug or key compromise can affect everyone using the bridge.

What is a wrapped token?

A token on one network that represents an asset from another, backed by whatever the bridge or custodian holds. If that backing fails, the wrapped token can lose value.
