Subscan Multisig UI is a web Multisignature management tool. It's developed by the Subscan team. Developers are free to use the codebase to extend functionalities and develop unique user experiences for their audiences.
The backend project stores historical calls can be found here, and call data retrieved will be parsed and verified on the frontend.
This is a React-rewrite of previous Vue implementation.
- Create multi-signature account and send extrinsic
- Manage multi-signature wallets and extrinsic
- Support multiple networks that are based on Substrate development
- User-friendly UI
This application will not save your account's private key. All extrinsics initiated will be signed through the polkadot.js extension. Make sure you have installed the polkadot.js extension and created an account in it.
If you have installed the polkadot.js extension, you will be automatically connected when you enter the page. Please authorize SUBSCAN_Multisig access.

Manage multi-sig accounts
1. Click
to enter multi-sig account details
2. In the multi-sig account details, you can either edit the wallet name or delete the wallet by click the correspond icon.
Click "Initiate extrinsic," enter the parameters, choose the submission method you want, click the corresponding button to submit
The member account that initiates the multi-sig transfer needs to hold a few token balance to pay for the network fees. Otherwise, the extrinsic will fail, and an error of "LiquidityRestrictions" will be raised.
-
As shown in the figure,
a red badge on the button indicates there is at least one pending transaction in this wallet.
-
Click to view the multi-signature account details. After confirming that the extrinsic call data is correct, click "Approve" and approve the extrinsic.
*For externally initiated extrinsics, call data may not be stored on the chain or in the database. Therefore, in the last "approved" extrinsic, you need to manually fill in the call data.
-
When the number of approvals reaches the threshold, the extrinsic will be executed.
Only the initiator has the authority to cancel the multi-sig extrinsic. Click "Cancel" and sign the extrinsic to cancel.
All networks are configured in src/config/chains folder, You can take polkadot.json as an exmaple:
{
"name": "polkadot",
"displayName": "Polkadot",
"rpc": "wss://rpc.polkadot.io",
// Optional (Delete this line in PR!)
"api": {
"subql": "https://api.subquery.network/sq/itering/multisig-polkadot"
},
"logo": "/image/polkadot-button-mobile.png",
// Optional (Delete this line in PR!)
"explorerHostName": "polkadot",
"themeColor": "#e6007a"
}
After completing the above json config file, you can place it under src/config/chains, and submit a PR targeting master branch, once it's approved, multisig APP will display your network in the list.
In order to support advanced features such as transaction history, you need to deploy your own subquery endpoint, and add it to the json file above. You can fork from the subscan multisig subquery repo and add support for your network.
