## Quick answer
A crypto bridge holds the original and issues a claim elsewhere. That claim is credit risk on the operator, and the queue for redemptions decides who loses.

## Summary
Lock-and-mint bridges hold your asset and issue a claim on another chain. This covers both bridge models, why the wrapped token is credit risk, and where backing quietly disappears.

## FAQ
Q: Does a crypto bridge actually move my tokens?
A: No. The original stays on the source chain, held by a contract or an issuer. What crosses is a message authorising a mint or a release on the far side.
Q: Is a wrapped token the same as the original?
A: Only in price while the bridge is solvent and honouring redemptions. Mechanically it is a separate claim on a separate entity, and it can trade below the underlying.
Q: Why do bridges get targeted more than other contracts?
A: Because the value sits in one place and the release paths are complex, spanning two chains and at least one off-chain relaying step. Complexity plus concentrated value is the pattern, not a single bug class.
Q: Can I verify that a bridge is fully backed?
A: Sometimes. If the lock address is public you can compare its balance with the wrapped supply, which is a real check. If the bridge keeps an off-chain ledger, you rely on disclosure rather than verification.
Q: Is it safer to bridge or to hold on the destination chain?
A: It depends on how long you intend to stay. Every crossing adds a contract risk to a position; holding the native asset avoids that risk but may put it where you cannot use it.
Q: Do rules for bridge operators differ by country?
A: Yes, substantially. Treatment of wrapped assets, custody, and transfer reporting varies by jurisdiction and rules change. Check what applies where you live rather than relying on general descriptions.
