PoS mainnet multi-signatures

Purpose and capabilities

The primary role of multi-signature wallets (multisigs) is to facilitate contract upgrades during the early stages of development. As these contracts become more robust, Polygon plans to:

Transition from multisigs to governance-controlled proxies.
Implement timelocks for added security.
Phase out multisigs entirely in the long term.

Censorship

It's important to note that 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 `0xFa7D2a996aC6350f4b56C043112Da0366a59b74c`
Purpose	To upgrade PoS and staking contracts on Ethereum.
Chain	Ethereum
Rights	- Update staking contracts for optimizations and upgrades. - Address unexpected bugs in PoS contracts.
Signatories	Quickswap, Curve, Polygon, Horizon Games, Cometh

Polygon commitchain multisigs

Multisig Address	$5/8$ Multisig `0x355b8E02e7F5301E6fac9b7cAc1D6D9c86C0343f`
Purpose	To update custom ChildERC20s on Polygon commitchain.

Permissionless mapping

Multisig address	Permissionless mapping of standard ChildERC20 tokens (no multisig required)
Purpose	FxPortal supports permissionless token mapping of standard ChildERC20 for any ERC20 token on Ethereum.
Chain	Permissionless
Rights	Permissionless
Signatories	Permissionless

_{*Plans are underway to transition these functions to governance. We are currently exploring options such as Aave's governance contracts and Compound’s timelock contracts.}
