Sahara multisig

Sahara Multisig is a new kind of dynamic-membership multisig for EVM-based blockchains.

The membership is dynamic, new members may join and/or be kicked over the lifetime of the contract. At any time, members can cast a vote (ex: "kick 0xabcdef", "welcome 0xhijklm"), if 66.6% threshold is reached (same vote for 66.6%+ members), the action is executed.

Actions

4 Actions :

• None (0): null/nothing vote.
• Welcome (1): Welcome a user into the multisig, identified by Ethereum address.
• Kick (2): Kick a user out of the multisig.
• Leave (3): Leave the multisig, not subjected to the 66.6% rule, can be executed unilaterally.
• Withdraw (4): Divide the contract's balance by the number of members, transfer equal portion to each.
• WithdrawToken (5): (Coming soon) Same but for ERC20 token (ex: USDC, USDT etc.)
• UdateTheshold (6): (Coming soon) Update threshold to another value (50%, 90%, else).

Contract is protected from replay attacks, anytime an action is executed, majority votes are reset to None (0), minority votes are left unchanged.

Recursiveness

A multisig contract can be member of another multisig.

Deploy

Coming soon

Command Line Interface

Coming soon

We're soon releasing a CLI to deploy, interact with and monitor a Sahara Multisig contract.

History

This repo is a solidity release of a multisig contrct based on RChain/rholang I developed few years ago.
