Connecting to a DeFi wallet

We usually need a DeFi wallet to access blockchain when we perform transactions, such as transferring cryptocurrencies, approving an operation, and performing all privileged operations. In Chapter 2, Getting Started with DeFi Application Development we have gone through how we can use Hardhat to deploy smart contracts and call smart contract functions using the DeFi wallet. In this section, we will explore how we can integrate the DeFi wallet with DeFi applications.

The architecture of DeFi wallet connectivity with blockchain

We need to understand a few concepts and DeFi wallet architecture before implementing the wallet connections. When designing a DeFi application, it requires the multi-layer architecture shown in Figure 3.2 when an application wants to access blockchain with DeFi wallets.
