Summarized Transcript: "5 – How to Use Paymaster on ZKsync Layer 2 with Web3.js"
In this video, a Web3 DeFi tech editor demonstrates the use of PayMaster on ZKsync Layer 2 with Web3.js. PayMaster is a contract that enables approvals of tokens on a layer 2 chain. The editor explains the process of sending Ethereum and tokens using PayMaster, including initialization, wallet creation, token approval, and transaction execution.
The video covers three examples:
- Sending Ethereum: The editor transfers 0.1 Ethereum to a recipient address, using PayMaster to pay for the transaction.
- Sending Tokens: The editor sends 4 DRC20 tokens to the same recipient address, using PayMaster to pay for the transaction.
- Withdrawing Tokens: The editor with draws 0.2 tokens from a previous transaction, using PayMaster to pay for the withdrawal.
Throughout the examples, the editor explains the PayMaster parameters, such as the contract address, approval token, and minimal allowance. They also demonstrate how to use a smart account and wallet to interact with PayMaster, and how to check balances before and after each transaction.
The video aims to provide a comprehensive guide on how to use PayMaster on ZKsync Layer 2 with Web3.js, making it easier for developers to integrate this technology into their projects.
Did you know? ZKsync Layer 2 is a scaling solution that makes it cheaper and faster to deploy and interact with smart contracts on Ethereum. Web3.js is a JavaScript library that provides a simple interface to the Ethereum blockchain, allowing developers to build web3 applications.
