i would say that bridging between top chains isn't that difficult because they have good documentation & many tools- while for the newer ones it's usually more challenging as they tend to have little documentation & no tools, i haven't used blockchains n their testing phase before but it's an interesting subject- what chains do u recommend ? also the youtube video with few views that u mentioned seems interesting- what's the name of the video ?. it's great that u didn't give up & figured out the solution- well done & have a great day
