My favorite chain breaker service has to do with kidney transplants:

Some economists noticed a few cases where would-be kidney donors who weren't compatible with their family member who needed a kidney were able to find another incompatible donor-recipient pair, and were able to swap so that each donor was able to gave to the other donor's loved one.

Of course, this only works if the medical compatibility works out between the pairs. To facilitate more transplants, economists created a donor-matching network that could handle cases where three incompatible donor-recipient pairs (or even thirty!) could work out an exchange allowing all of the recipients to get a suitable kidney. Naturally, laws prevent money from changing hands for kidneys, everywhere on earth except in Iran.
