Ethereum Multisignature Wallet

This repo has been deprecated and replaced by Safe Multisig. Please find the Safe repository here: https://github.com/gnosis/safe-contracts

An instance of Multisig website is available on IPFS at: https://ipfs.infura.io/ipfs/QmfRD4GuqZobNi2NT2C77a3UTQ452ffwstr4fjEJixUgjf

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 Ether and all kind of tokens with multisig support
Easy to use offline signing (cold wallet) support
Integration with web3 wallets (Metamask, Mist, Parity, etc)
Transaction data and log decoding, makes transactions more readable
Interacting with any contracts with UI support
Hardware wallet support (Ledger Wallet)
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

FAQ

How to set a custom Ethereum Node?

You can specify a custom Ethereum Node endpoint by going to settings page. Click on Ethereum Node dropdown menu and select Custom configuration, this would make the Ethereum node's field editable. Please write your new endpoint there. Remember, if Web3 Provider is set to Default (Metamask, Mist, Parity), Multisig will use the Ethereum Node endpoint coming with the Web3 Provider, so in that case go to your injected Web3 Provider (Metamask for instance) and update/switch your Ethereum Node endpoint.

I've imported a Multisig address or a contract address into address book but it gets detected as a EOA

Make sure you're connected to the same network your Multisig/contract was created on, if you created it on Mainnet, you should then connect to Mainnet in order to let the system detect its type correctly.
