Usage
import the package:
import TrustWallet, {CoinType} from '@trustwallet/rn-sdk'initialize an instance, e.g. in componentDidMount:
const wallet = new TrustWallet('<your_app_scheme>://');request ETH/BNB accounts:
wallet.requestAccounts([CoinType.ethereum, CoinType.binance])
.then((accounts) => {
Alert.alert('Accounts', accounts.join('\n'))
}).catch(error => {
Alert.alert('Error', JSON.stringify(error))
})sign an Ethereum message:
const message = utils.keccak256(this.ethereumMessage("Some message"))
wallet.signMessage(message, CoinType.ethereum)
.then((result) => {
Alert.alert('Signature', result)
}).catch(error => {
Alert.alert('Error', JSON.stringify(error))
})sign an Ethereum transaction:
// tx should comply TW.Ethereum.Proto.ISigningInput from @trustwallet/wallet-core
const tx = {
toAddress: '0x728B02377230b5df73Aa4E3192E89b6090DD7312',
chainId: Buffer.from('0x01', 'hex'),
nonce: this.serializeBigInt('447'),
gasPrice: this.serializeBigInt('2112000000'),
gasLimit: this.serializeBigInt('21000'),
amount: this.serializeBigInt('100000000000000')
}
wallet.signTransaction(tx, CoinType.ethereum, send)
.then(result =>{
Alert.alert('Transaction', result)
}).catch(error => {
Alert.alert('Error', JSON.stringify(error))
})clean up all resolve handlers, e.g. incomponentWillUnmount:
wallet.cleanup();Contributing
