How OBOL rates bridges

Bridges have lost more money than any other category in crypto — well over two billion dollars across the sector's history. That is why trust assumptions carry the heaviest weight in this rubric. The question is not whether a bridge is decentralised in its marketing, but exactly whose signature, key or honesty stands between you and your funds.

Exploit history is weighted almost as heavily, and we look at the class of failure. A validator key compromise says something different about an operator than a signature verification bug does, and a protocol that has fixed one specific bug has not necessarily fixed the category of mistake that produced it.

Canonical, native and liquidity bridges are not comparable

A rollup's canonical bridge inherits the security of the chain itself and is slow by design. A message-passing bridge depends on an external validator set. A liquidity network never moves assets across chains at all — it pays you out of a local pool. These are different risk products and we say which one you are using in every review.

Our standing advice

Bridge only what you need, when you need it, and do not treat a bridged position as long-term storage. Where a canonical bridge exists for the route you need and you are not in a hurry, it is almost always the lower-risk choice.

FAQ

Why are bridges attacked so often?
Because they concentrate large balances behind a small number of keys or a single verification routine, and because the code has to be correct across two chains at once. It is the highest value-to-complexity ratio in crypto.
Is a fast bridge less safe?
Not inherently. Intent-based bridges are fast because a relayer fronts you funds and takes the settlement risk themselves. That can be safer for you than a validator-set bridge, and the relayer is compensated for it.
What should I check before bridging a large amount?
Whether a canonical route exists, how long the bridge has operated at the size you are sending, and whether the receiving asset is the native one or a wrapper you will need to unwind later.
