Note:
   I am presently mistrusting the bundler services.
   - I was told in their chat they charge a 30% fee
   - Their server software appears to me to be closed source. It is
   possible that that's network censorship or obtuseness on my end.
   - My data yesterday was held off-chain with my funds and is now still
   beginning seeding in response to me visiting their chat and asking
   about it repeatedly today.
