   @josibake Sent you some, using a light client so I hope this worked.

   @setavenger received, 0.00021000! I tried sending it back but it appears your address is invalid PEBCAK. I’d like to keep this issue focused on the integration for Bitcoin Core, but feel free to join the silent payments IRC channel (#silentpayments) or reach out on twitter (@josibake) so we can keep testing!

   • Move base protocol to libsecp as a module (not started)

   FWIW, I’ve started digging a bit deeper into that and started a corresponding discussion in the libsecp256k1 repo: https://github.com/bitcoin-core/secp256k1/issues/1427 (still trying to figure out a sane interface…)
