# Safe Contracts Den is built on the Safe Contracts with no additional smart contract code. ### Safe Contracts Safe is a self-custodial, multi-signature wallet. A multi-signature wallet require multiple parties using individual wallets to sign a transaction before it is executed. The rules of execution are defined in an `n-of-m schema`, where `n` is the minimum number of signers needed for a transaction to execute and `m` is the total number of signers on a wallet. For example, on a `2-of-3` multi-signature wallet there are 3 total signers on the wallet, but only 2 of them need to provide signatures for a transaction to execute. Safe is deployed on Ethereum and a several other EVM (Ethereum Virtual Machine) Chains. It currently stores over 5% of all cryptocurrency. You can find more usage data for Safe here (data only covers Ethereum Mainnet): ### SafeDAO and Governance Delegation The Safe Contracts and infrastructure are stewarded by the SafeDAO, a decentralized autonomous organization consisting of contributors across the Safe ecosystem. Den actively votes in SafeDAO governance proposals as a delegate. If you hold $SAFE tokens, you can delegate your votes to Den on [Snapshot](https://snapshot.org/#/delegate/safe.eth) to either * jgov.onchainden.eth * igov.onchainden.eth Den's voting decisions are shared publicly on [Twitter](https://twitter.com/search?q=from%3A%40onchainden%20SEP\&src=typed_query\&f=top).
