MMGen Wallet implements Monero 'offline transaction autosigning'

MMGen Wallet¹, the command-line online/offline multi-crypto wallet, has implemented Monero offline transaction autosigning²:

Cold signing of Monero transactions with maximum convenience. [..] A unique security feature is that signing wallets are created afresh in volatile memory for each transacting session and thus disappear when the signing machine is powered down.

Run mmgen-xmrwallet --help for documentation about offline autosigning in MMGen. For general information about Monero offline signing, visit monerodocs.org³.

To support the project, transfer some XMR to the donation address listed at the bottom of the README.md⁴ file on Github.

Consult the previous Monero Observer report⁵ to learn more about MMGen.

Note: inspect the code before using, if you can read Python.
