This opens the door to using, for example, a https://github.com/gnosis/MultiSigWallet[Gnosis Multisig] or https://safe.gnosis.io[Gnosis Safe], an https://aragon.org[Aragon DAO], an https://www.uport.me[ERC725/uPort] identity contract, or a totally custom contract that _you_ create.

 In this way you can use _composability_ to add additional layers of access control complexity to your contracts. Instead of having a single regular Ethereum account (Externally Owned Account, or EOA) as the owner, you could use a 2-of-3 multisig run by your project leads, for example. Prominent projects in the space, such as https://makerdao.com[MakerDAO], use systems similar to this one.

 For all of these options, the Governor will be compatible with Tally: users will be able to create proposals, visualize voting power and advocates, navigate proposals, and cast votes. For proposal creation in particular, projects can also use Defender Admin as an alternative interface.

 The data signer can be recovered with xref:api:cryptography.adoc#ECDSA-recover-bytes32-bytes-[`ECDSA.recover`], and its address compared to verify the signature. Most wallets will hash the data to sign and add the prefix '\x19Ethereum Signed Message:\n', so when attempting to recover the signer of an Ethereum signed message hash, you'll want to use xref:api:cryptography.adoc#ECDSA-toEthSignedMessageHash-bytes32-[`toEthSignedMessageHash`].
