The 9 greatest crypto bridges: Inspecting prime selections for transferring tokens between blockchains
It’s vital to say that blockchain bridges have, sadly, been a extremely popular goal for exploits. In truth, a few of the greatest hacks and exploits that we have now seen so far have focused bridges. Bridging tokens between blockchains continues to be a comparatively new idea, and lots of implementations have been uncovered for having vital vulnerabilities that the builders didn’t catch earlier than deploying their bridging options.
So, when bridging tokens between blockchains, we advocate exercising some warning and by no means committing greater than you may afford to lose. Given the historical past of blockchain bridge hacks, it’s in all probability smarter to err on the facet of warning even when utilizing a preferred and respected bridging answer.
