Is Mpurse safe?

Low risk

Mpurse lets HTTPS pages invoke selected mpchain.info JSON-RPC proxy calls through its content-script bridge.

Mpurse exposes a page bridge on HTTPS sites that can forward same-page requests for mpchain, CounterBlock, and Counterparty JSON-RPC methods. Those requests are sent through the extension background code to mpchain.info without the origin approval used for address, send, or signing flows.

Part of this rating comes from analysis signals we haven't published as detailed findings yet.

Where it sends data

Destinations our analysis observed Mpurse contacting. Sending data somewhere is not a finding on its own - an extension that syncs your settings has to talk to its own server - but it is where your data can go, and who else it goes to.
