DSGroup

Multisig with a command-line interface

The ds-group library is DSGroup with a command-line interface. A list of members, the required quorum and the window of time in which actions must be approved are fixed when the DSGroup contract is created. Actions can then be proposed, confirmed and triggered once a group quorum has been reached.

Installation & deployment

The DSGroup contract takes three parameters:

function DSGroup(address[] members, uint quorum, uint window)

address[] members

The list of group members. They will be able to create new proposals, accept them and trigger their execution.

uint quorum

The minimum number of members who have to accept a proposal before it can be triggered.

uint window

The proposal validity time in seconds.

Install Dapp to build and deploy the contract:

dapp build
dapp create DSGroup '[
  0011111111111111111111111111111111111111,
  0022222222222222222222222222222222222222,
  0033333333333333333333333333333333333333
