Ethereum wallet using an ERC-20 smart contract.
A digital wallet app, developed in dart language and flutter framework. 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.
- 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

How to watch/build autogenerated files
$ flutter packages pub run build_runner build # to build
$ flutter packages pub run build_runner watch # to watchHow to run the app
$ flutter pub get packages
$ flutter packages pub run build_runner build
$ flutter runrunning on the browser
$ flutter run -d web-serverHow to run tests
$ flutter testFor those who don't want to play with smart contracts yet, you can claim some test coins (tokens) and ether using the following links or check out 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 ETH to pay transaction fees, called gas. You also can claim some to test your wallet. Each network has its own faucet.
- Ropsten: https://faucet.ropsten.be/
- Polygon (old MATIC): https://faucet.polygon.technology/
- BSC: https://testnet.binance.org/faucet-smart
just be patient, the transaction might take a while to be processed.
