SafeX

Mostly everyone have used Safe's Multisig in Web3 but one issue with it is that it can only be deployed on Single chain. -> Let's say one user has funds on Optimism and one on Polygon so in this case they can't create a multisig in which widthrawl requires permission of both parties. -> Safe-X solves this issue using Hyperlane's Queries API.

How it is made : ->So firstly a user will create a safe with two signers,one himself(by default) and one from another chain(Avax,Mumbai,Sepolia). A unique safe Id will be assigned to this safe . Eg(10). -> The second user can sign a transaction of Approval from his chain with the Safe Id provided and that approval will be recorded on the base contract using Hyperlane's Query Api. -> For widthrawl we are checking if both the owners of the safe have accepted transaction or not. -> The user can store USDCs in the contract and further for widthrawl it can provide the address,safeId and ChainId to which the USDCs needs to be transfered. -> Using Circle's CCTP we are burning USDC on base chain and minting USDC to the specified address and Chain . -> After the widthrawl we are resetting the signing status of the safe,for new widthrawl,both users needs to sign again .
