​Even though bridges have been critical in enabling capital to move freely across ecosystems, they’ve also become one of the biggest attack surfaces in crypto. Over the years, billions of dollars have been lost to bridge exploits.

​Why so many bridge exploits? Is it flawed design? Weak implementations? Or deeper structural tradeoffs that we’ve yet to fully understand?

​Let's look into all of this together at our next whitepaper reading in Lagos. To get you ready, we’ve curated a set of resources below.
