Safe Vault is a set of open source and trustless Ethereum smart contracts. it can safely "escrow" all your incoming funds (ETH and ERC20 assets), and only lets it's owner withdraw according to a pre-defined ratio .
Each Vault is a contract wallet without private key, so never worry about losing the private key, you can think of it as an on-chain safe, send funds to it, and only owners can withdraw..
In terms of security, Vault really shines. Because each Vault is immutable and has no 3rd party reliance, everything is on IPFS and Ethereum (and Polygon, etc.)
Safe Vault is versatile. you can use it in a variety of situations. You can use it as the smallest module in a DAO, as a recipient of NFT contract royalties, as a way to distribute funds among NFT collaborators, etc., Therefore can treat Vault as low level building blocks and build the addresses into oher contracts, and they will work deterministically forever.
Safe Vault is powered by merkle trees. Normally dealing with merkle trees is complex and requires offchain storage, and often results in some business running it as a centralized service. But not with Safe Vault. You DO NOT need to rely on a 3rd party. Here's how it works::
Therefore Vault does not have any centralized cloud that stores your merkle trees, and has no 3rd party reliance. Everything is on IPFS and Ethereum. Anyone can host Vault on their own.
