 The Filecoin Native [MultisigActor](/basics/the-blockchain/actors#multisigactor) is a built-in actor that does not interact directly with the Filecoin EVM. Like other Filecoin actors, native multisig addresses begin with `f2` and represent a group of transaction signers with a maximum of 256 signers. Signers may be external users or the MultisigActor itself and can include `f1` and `f3` [addresses](https://docs.filecoin.io/basics/the-blockchain/addresses).
 
-A [MultisigActor CLI](https://lotus.filecoin.io/lotus/manage/multisig/) is available from the Lotus CLI, and a web UI for MultisigActors is available at https://www.glif.io/en/multisig/.

 - **Signing a transaction** from an account with no previous activity on the Filecoin blockchain will fail. You can send a transaction to this account with zero funds to initiate its on-chain activity to work around this issue.
 - **Executing a transaction** can produce gas estimation issues for accounts that have a very small amount of funds (that would not or would barely cover the transaction).
 - **Transaction confirmation times** may lead to prolonged "processing" status in the UI.
