MYMULTISIG — SHARED WALLETS, ENFORCED ONCHAIN

No single key can move the funds.

Create a shared wallet, choose its owners, and set how many must approve. Every transaction waits for that quorum—then anyone on the team can execute it.

A 2-of-3 multisig: once two owners sign, any owner can execute.

How it works

01

Create a multisig

Deploy a shared wallet on your chosen chain. You pick the network and get a new multisig address.

02

Add owners and set the threshold

Define who can sign and how many approvals are required before any transaction can run.

03

Propose and approve transactions

Any owner can propose a transaction. Once enough owners approve, any owner can execute it.

open-source

Open source

Contracts and app code are available for review. No hidden logic—what you see is what runs.

FAQ

What is a multisig?

A multisig (multi-signature) wallet is a shared wallet that requires multiple people to approve a transaction before it can be executed. No single person can move funds alone.

Why would I use one?

Multisigs are useful whenever you want shared control: team treasuries, community funds, protocol reserves, or any situation where you do not want one key to have full control.

Do all owners need to approve every transaction?

No. You set a threshold when creating the multisig (e.g. 2 of 3). Once that many owners have approved a proposal, the transaction can be executed. Not everyone has to sign every time.

Is the project audited?

No. MyMultiSig is an early-stage project. The contracts are open-source and available for review, but they have not been professionally audited. Use at your own risk.

Where can I review the code?

The smart contracts and this web app are both on GitHub. Use the "Review the code" link in the footer or on this page to open the repositories.
