Ethereum 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.

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

Being used by

• Aragon
• Bancor
• Brace
• District0x
• Golem
• MysteriumNetwork
• Weifund
• StabL

Install

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.
