Pony Direct is a proof-of-concept Android app developed by Samourai as part of the Mule.Tools research and development initiative exploring alternative means of transaction broadcasting to enhance censorship resistance. Pony Direct can be used for transmitting transactions to the bitcoin network via SMS. Send your own transactions by SMS using a known Pony Relay or allow your own contacts to use your mobile number as an SMS relay.

A github repository called Pony Direct was opened by Samouri wallet coder, Samouridev. It is a proof-of-concept software for Android phones. The Pony Direct system allows a user to execute Bitcoin transactions without being connected to the internet. The transactions occur via SMS. A user texts the transaction to a relay device, which acts as a payment proxy. The purpose of such a tool is to circumvent inevitable censorship in authoritarian regions or to enable those with poor/no internet connectivity to commit to the global market Bitcoin provides.
