An exchange-operated bridge holding $6.31bn across five chains, moving assets between mainnet and the exchange's Layer 2.
Our assessment
Coinbase Bridge holds $6.31bn across five chains, operated by a US-listed exchange and serving primarily as the route between Ethereum mainnet and its own Layer 2. No audit report was retrievable at a public address at this check.
A listed operator is real evidence, of a specific kind
An exchange filing audited accounts with the SEC is more accountable than an anonymous protocol team, and it has both assets and a reputation at stake. That tells you something about the operator's incentives and nothing about the contract's correctness — and $6.31bn sits in the contract.
Standard rollup bridges have known properties
Where the bridge is the canonical route for an optimistic rollup, withdrawals to mainnet carry a challenge period measured in days. That is a documented characteristic rather than a defect, and it is the thing users are most often surprised by. Faster exits exist through third-party liquidity providers, at a cost and with different risk.
What is missing from the record
No audit report at a public address, with thin transparency results at conventional addresses. For a contract of this size operated by a company with substantial resources, publishing the reviews would be straightforward.
Who it suits
Coinbase Bridge fits users moving assets to and from its Layer 2, where it is the canonical route. Users bridging between other chains should compare Portal or CCIP.

Frequently asked
Does this score mean Coinbase Bridge is safe?
No. It measures what an outsider can verify: linked audits, published methodology and independently recorded data. Contract and custody risk are not tested by us.
Where do these figures come from?
A public analytics dataset queried at the verification date, plus the audit reports it links. Anyone can re-run the query.
Why do some protocols score zero on audits?
Because no audit report is linked in the public record. It records what a user can reach, not a claim that no audit exists.
