Ethereum wallet using an ERC-20 smart contract.

A digital wallet app developed in dart and flutter. The idea is to help developers to understand how to build dApps using blockchain and associated technologies. This app can transfer tokens from one wallet to another through an ERC-20 Ethereum contract.

What's being used

• Built in Flutter framework
• QR code scanner to scan addresses
• Web3Dart to interact with Ethereum blockchain
• Flutter hooks to manage widget life-cycle.
• Solidity smart contract

Wallet balance

For those who don't want to play with smart contracts yet, you can claim some test tokens by following links below, or check this repo to understand how to deploy your own contract.

Transfer test TOKENS to your wallet:

After setting up your wallet, you will need some tokens to play with. Use the link below to transfer some tokens to your wallet.

Transfer test Ether to your wallet

To process transactions on the network, you will also need coins to pay the transaction fees (gas). Use one of the following links to claim some coins depending on the network you are working on:

• Goerli: https://goerlifaucet.com/
• Polygon (old MATIC): https://faucet.polygon.technology/
• BSC: https://testnet.binance.org/faucet-smart
