# PoS mainnet multi-signatures

> Reference for active multi-signature wallets on the Polygon PoS mainnet and commitchain.

Multi-signature wallets (multisigs) control contract upgrades on Polygon PoS.

<Note title="Censorship">
  The existing multisigs do not have the capability to censor transactions, including bridge transactions.

## Active multi-signature wallets

### Ethereum chain multisigs

| Multisig Address | **$5/9$ Multisig**<br />`0xFa7D2a996aC6350f4b56C043112Da0366a59b74c`                                        |
| :--------------: | ----------------------------------------------------------------------------------------------------------- |
|      Purpose     | To upgrade PoS and staking contracts on Ethereum.                                                           |
|       Chain      | Ethereum                                                                                                    |
