NXTChain Multisignature Wallet

The purpose of multisig wallets is to increase security by requiring multiple parties to agree on transactions before execution. Transactions can be executed only when confirmed by a predefined number of owners. A web user interface can be found here.

NOTE: Not compatible with current NodeJS LTS. Recommended NodeJS version is v6.17.1 (last LTS for v6).

Features

• Can hold NXT and all kind of tokens with multisig support
• Easy to use offline signing (cold wallet) support
• Integration with web3 wallets (NXTWallet, Metamask, Mist, Parity, etc)
• Transaction data and log decoding, makes transactions more readable
• Interacting with any contracts with UI support
• Optional email notifications when an event is triggered or you are required to sign a transaction

Install

# For Ubuntu/Debian you need to install libusb development headers
apt install -y libusb-1.0-0-dev

git clone https://github.com/gnosis/MultiSigWallet.git
cd MultiSigWallet

# Latest NodeJS (v12.13.0) does NOT appear to work correctly.
# You should use NVM and install Node v6.17.1 for best results: https://github.com/nvm-sh/nvm
# Tested by @Privex on 2019-Nov-06 with v6.17.1 with success
nvm install v6.17.1

# node-gyp is required for 'npm install' to work correctly
npm install node-gyp

npm install

Test

Run contract tests:

npm test

Run interface tests:

npm run test-dapp

Deploy Contracts

Deploy multisig wallet:

truffle migrate <account1,account2,...,accountN> <requiredConfirmations>

Deploy multisig wallet with daily limit:

truffle migrate <account1,account2,...,accountN> <requiredConfirmations> <dailyLimit>

Limitations

This implementation does not allow the creation of smart contracts via multisignature transactions. Transactions to address 0 cannot be done. Any other transaction can be done.
