React Native components and hooks for fast building dApps without running own backend
This project is using:
- create-react-native-dapp to bootstrap the project.
- WalletConnect v1 react-native integration for authenthication (we use a slightly modiefied version, located in
./src/WalletConnect
to allow to modify theenable
function of Moralis). - react-moralis for react hooks
There are many components in this boilerplate that do not require an active web3 provider, they use Moralis Web3 API. Moralis supports the most popular blockchains and their test networks. You can find a list of all available networks in Moralis Supported Chains
Please check the official documentation of Moralis for all the functionalities of Moralis.
Check the corresponding docs for additional information and help.
