This is a proof of concept implementation which shows how to set up and use a Gnosis Safe with Infineon Security2Go Smart Cards as owners.
Development was supported by the Gnosis Ecosystem Fund, see the "Multicard" application.
The application consists of a local webserver that connects to a local NFC reader (see requirements).
the Web UI guides you through different steps of the lifetime of a Safe:
- Deploying a new Safe from scratch
- Initializing a set of owners for multisig
- Funding that Safe with 1 unit of native currency
- Getting out 0.1 units of native currency using a Safe transaction with multiple signatures
- A NFC Card reader that is supported by PCSC lite
- In order to install the package you need to have installed in the system the pcsclite libraries. For example, in Debian/Ubuntu:
apt-get install libpcsclite1 libpcsclite-dev - Access to an Ethereum compatible blockchain - we use ARTIS tau1 (testnet) in this example
- At least one Security2Go NFC Card (3 recommended - 1 for setting up and funding the Safe, 2 for multisig)
- with address at index 1 initialised
- with some funding (at least 1.5 ATS for ARTIS)
- Linux OS - tested with Ubuntu 18 LTS - but most other common Linux distros should do as well
- libudev and libusb 1.0.8 or later
- Node.js v10 LTS (tested with v10.15.3)
- NPM (tested with v6.4.1)
npm ci
npm start
This pops up a web server on port 3000.
Navigate to http://localhost:3000 in a browser of your choice and follow the instructions.
