The objective of the quest is simple, to create one of these Ethereum wallets, at least to implement the main functions:
Consult his balance the balance of his Tokens; 📈
Send ERC20 tokens;
Some reminders on Web3Js and the equivalents on EthersJs To instantiate a smart contract, ERC20 or another for that matter, on Web3JS, you have to do:
const contract = new Contract (abi, address) The equivalent on EthersJs is this:
const contract = new ethers.Contract (address, abi, signerOrProvider) If you only want to read the data from the smart contract, you have to add a provider. In the case of writing to change the state of a smart contract, it is instantiated with a signer.
Then to send tokens with Web3Js, you must use this instruction
contract.methods.transfer (address, amount) .send ({from: account}) And the EthersJs version:
contract.transfer (address, amount)
This is a Next.js project bootstrapped with create-next-app.
First, run the development server:
npm run dev
# or
yarn devOpen http://localhost:3000 with your browser to see the result.
You can start editing the page by modifying pages/index.js. The page auto-updates as you edit the file.
API routes can be accessed on http://localhost:3000/api/hello. This endpoint can be edited in pages/api/hello.js.
The pages/api directory is mapped to /api/*. Files in this directory are treated as API routes instead of React pages.

- Next.js Documentation - learn about Next.js features and API.
- Learn Next.js - an interactive Next.js tutorial.
You can check out the Next.js GitHub repository - your feedback and contributions are welcome!
The easiest way to deploy your Next.js app is to use the Vercel Platform from the creators of Next.js.
