This section is dedicated entirely to you building a fullstack Web3 DApp for a multisignature wallet. We have taken an extensive look at a single signature wallet called EtherWallet DApp where we developed the smart contract, built a frontend app and also rebuilt it again but using rainbowkit and wagmi react libraries. In this section, we’re going to be taking it a step further by letting you write an advanced version of the same wallet but this time implementing a multisignature wallet on top. So in principle, the process to deposit to the multisig wallet smart contract is the same however, the process to withdraw is slightly different in that it’ll require multiple signatures(i.e. Multiple wallets) before the transaction is successfully executed and the ETH is able to be withdrawn. Only the wallet owners will be able to create the withdraw transaction and approve the withdraw transaction similar to our EtherWallet smart contract whereby there was a single owner who could only withdraw ETH from the wallet.

Without further ado, let’s dive into this project.
