Most bridge transactions go off without a hitch, but there are risks. Centralized bridges or trust-based bridges bring the risks that come with any organization. They’re run by people who might make mistakes or may be dishonest. Decentralized (trustless) bridges run on computer programs, which may have bugs or could be hacked.
In addition, the bridged tokens don’t always track the base coin or token in value. The difference in price can add up if you’re working with large amounts of crypto.
